Bhattacharjee P, Sarkar P, Bhadra K. Evaluation of therapeutic role of harmaline: in vitro cytotoxicity targeting nucleic acids. JOURNAL OF ASIAN NATURAL PRODUCTS RESEARCH 2024; 26:519-533. [PMID: 37656039 DOI: 10.1080/10286020.2023.2251116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 08/17/2023] [Accepted: 08/17/2023] [Indexed: 09/02/2023]
Abstract
Use of small molecules as valuable drugs against diseases is still an indefinable purpose due to the lack of in-detail knowledge regarding proper bio-target identification, specificity aspects, mode-mechanism of binding and proper in vitro study. Harmaline, an important beta-carboline alkaloid, shows effective anti-proliferative action against different types of human cancers and is also found to be a nucleic acid targeting natural molecule. This review sought to address the different signal pathways of apoptosis by harmaline in different cancer cell lines and simultaneously to characterize the structure activity aspects of the alkaloid with different motifs of nucleic acid to show its preference, biological efficacy and genotoxicity. The results open up new insights for the design and development of small molecule-based nucleic acid therapeutic agents.

Abstract
Baobab (Adansonia digitata) fruit pulp has a high nutrient content and has been traditionally used for medicinal purposes (e.g., as an anti-inflammatory and antioxidant agent) that may help protect against chronic diseases. Six different baobab fruit pulp powders were investigated using three different extractants and analyzed by high-performance thin-layer chromatography (HPTLC) hyphenated with antibacterial bioassays and enzyme inhibition assays. The developed non-target effect-directed screening was performed after extraction with pentyl acetate - ethanol 1:1 (V/V) on the HPTLC plate silica gel 60 using toluene - ethyl acetate - methanol 6:3:1 (V/V/V) as mobile phase system and derivatization via the anisaldehyde sulfuric acid reagent for detection. The physico-chemical profiles of the six baobab fruit pulp powder extracts were comparable, although the intensity of some zones was moderately different. The following effect-directed profiling via tyrosinase, α-glucosidase, and acetylcholinesterase inhibition assays as well as antibacterial Aliivibrio fischeri and Bacillus subtilis bioassays revealed one prominent multipotent bioactive compound zone in common, more or less active in all five studied (bio)assays. Via the recording of high-resolution mass spectra, this compound zone was tentatively assigned to coeluting saturated (palmitic acid 16:0 and stearic acid 18:0), monounsaturated (oleic acid 18:1), and polyunsaturated (linoleic acid 18:2 and linolenic acid 18:3) fatty acids. This finding was confirmed by other studies, which already proved individual activities of fatty acids. The first (bio)activity profiling of baobab fruit pulp powders via HPTLC-effect-directed analysis revealed that the baobab fruit could be considered as a functional food, however, further research is needed to study the impact on health and the influences on the bioactivity arising from different climates, years and soils or regions.

Abstract
In current research, two functional components, i.e., hydrazone and bisphenol sulfide were combined to get useful supramolecules in medicinal chemistry. Herein 25 new 4,4'-thiodiphenol bis-acylhydrazones were synthesized in good to excellent yields. Initially ethyl-2-chloroacetate was reacted with 4,4'-thiodiphenol, which was further reacted with excess hydrazine hydrate to produce 2,2'-((thiobis(4,1-phenylene))bis(oxy))di(acetohydrazide), which was then combined with various aromatic and aliphatic aldehydes to get the desired products (hydrazones, 4a-4y). The synthesized supramolecules were characterized by contemporary spectroscopic techniques such as 1H NMR, 13C NMR, and mass spectroscopy. The synthetic compound's cholinesterase blocking activity was tested against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes where compounds 4n, and 4h showed excellent inhibitory potential for AChE, while 4b, and 4h, demonstrated most potent inhibition of BChE. The starting compound (SM3) and compounds 4h and SM3 depicted excellent dual inhibitory capabilities for both enzymes. The chemical basis of anticholinesterase activity was investigated using a structure-based molecular docking approach. The biological significance and the ease of synthesis of this class of compounds should be considered in therapeutic development for Alzheimer's disease treatments.

Abstract
In this study, a fast and precise method for determining three opium alkaloids (morphine, codeine, and thebaine) in different parts of some Papaver species was developed and validated with a low limit of detection (LOD) of 0.05 - 0.20 mg/L. The proposed method was based on three extraction steps by alkaline aqueous solution/chloroform/acidic aqueous solution and analysis by ion mobility spectrometry (IMS) and high-performance liquid chromatography (HPLC). After optimizing IMS parameters based on an experimental design, IMS was applied to analyze the extracts of seeds, stems, leaves, and capsules of seven Papaver species collected from different regions of Iran. All prepared samples were analyzed by HPLC and IMS at the same time. Then, the obtained results of the two instrumental methods were compared. The HPLC did not detect morphine in the prepared samples, while IMS results showed trace amounts of morphine in the capsules and leaves of four Papaver species. Other results were comparable and showed that IMS is more sensitive, affordable, and faster than HPLC for alkaloid analysis.

Abstract
The genus Peganum constitutes one of the perennial groups of plants of semi-arid regions across the world. It produces diverse classes of metabolites with claimed valuable pharmacological applications. Despite the key chemical and biological properties of the genus, its allelopathy or that of one of its species has not been reviewed yet. Thus, the present survey aims to report the agricultural applications of extracts, fractions, and compounds from the genus Peganum. This work was based on the available literature related to both the Peganum genus and agriculture, which were generated from available high-impact scientific engines. The plants in this genus contain a large group of secondary metabolites including phenolic compounds, terpenes, and N-containing compounds. Alkaloids, as the main components of the extracts from plants in the genus, were identified as the major active principles. The toxicity of Peganum isolates against plants and related pest organisms was also reviewed. Extract preparations from species of Peganum were listed among insecticidal and herbicidal allelochemicals used for crop protection. The review also tried to contextualize natural products in agriculture. Peganum plant extracts and fractions have showed significant potential in weed and crops management, soil health, and biopesticide production.

Abstract
Quinoline and quinazoline alkaloids, two important classes of N-based heterocyclic compounds, have attracted scientific and popular interest worldwide since the 19th century. More than 600 compounds have been isolated from nature to date. To build on our two prior reviews, we reexamined the promising molecules described in previous reports and provided updated literature on novel quinoline and quinazoline alkaloids isolated over the past 5 years. This chapter reviews and discusses 205 molecules with a broad range of bioactivities, including antiparasitic and insecticidal, antibacterial and antifungal, cardioprotective, antiviral, anti-inflammatory, and other effects. This survey should provide new clues or possibilities for the discovery of new and better drugs from the original naturally occurring quinoline and quinazoline alkaloids.

Abstract
Quinazolines are considered as a promising class of bioactive heterocyclic compounds with broad properties. Particularly, the quinazoline scaffold has an impressive role in the design and synthesis of new CNS-active drugs. The drug-like properties and pharmacological characteristics of quinazoline could lead to different drugs with various targets. Among CNS disorders, Alzheimer's disease (AD) is a progressive neurodegenerative disorder with memory loss, cognitive decline and language dysfunction. AD is a complex and multifactorial disease therefore, the need for finding multi-target drugs against this devastative disease is urgent. A literature survey revealed that quinazoline derivatives have diverse therapeutic potential for AD as modulators/inhibitors of β-amyloid, tau protein, cholinesterases, monoamine oxidases, and phosphodiesterases as well as other protective effects. Thus, we describe here the most relevant and recent studies about anti-AD agents with quinazoline structure which can further aid the development and discovery of new anti-AD agents.

Abstract
Peganum harmala L. contains 17 alkaloids of quinazoline and indole structure types. Of these, harmaline, harmine, harmalol and L-peganin (vazicin) are pharmacologically active. It was established that of the alkaloids contained in the seeds, 50-95% is dominated by harmaline, harmine is dominated in the roots (67-74% of the total of extractive substances), and in the aerial part, the main mass is peganin (up to 78% of the total of alkaloids). Beta-carboline alkaloids of Peganum harmala L. inhibit monoamine oxidase, thereby exerting a neuroprotective effect.
This article is devoted to the results of studies of the neurotropic action of harmine hydrochloride, when compared with the activity of the reference drug “Amitriptyline”. It was shown that the use of harmine hydrochloride helps to reduce the level of anxiety in animals under conditions of experimental psychoemotional chronic stress with prolonged administration. In the study of acute and chronic toxicity, it was determined that harmine hydrochloride belongs to the category of moderately toxic substances (hazard class II). According to the results of molecular docking, the presence of strong bonds in harmine hydrochloride with the serotonin 5-HT2C receptor, dopamine D2 receptor, as well as monoamine oxidase A and B was revealed, which indicates the implementation of the mechanism of neurotropic action of harmine hydrochloride at the level of synaptic neurotransmission of monoamines (dopamine, serotonin and others). It was also established that harmine hydrochloride eliminates haloperidol-induced catalepsy in rats, reduces oligokinesia and rigidity in the Parkinson’s test, has antihypoxic activity in the hypobaric hypoxia test, and exhibits pronounced antidepressant activity in the Porsolt’s test. In the course of the study of pharmacokinetics and bioavailability, it was revealed that with the administration of harmine hydrochloride, the quantitative content is quickly achieved and the concentration of the active substance in the blood significantly increases. The relative bioavailability of harmine hydrochloride is 112.7%.

Abstract
The genus Peganum includes four species widely distributed in warm temperate to subtropical regions from the Mediterranean to Mongolia as well as certain regions in America. Among these species, Peganum harmala L., distributed from the Mediterranean region to Central Asia, has been studied and its phytochemical profile, traditional folk use, and application in pharmacological and clinical trials are well known. The review is aimed at presenting an insight into the botanical features and geographical distribution of Peganum spp. along with traditional folk uses. This manuscript also reviews the phytochemical profile of Peganum spp. and its correlation with biological activities evidenced by the in vitro and in vivo investigations. Moreover, this review gives us an understanding of the bioactive compounds from Peganum as health promoters followed by the safety and adverse effects on human health. In relation to their multipurpose therapeutic properties, various parts of this plant such as seeds, bark, and roots present bioactive compounds promoting health benefits. An updated search (until December 2020) was carried out in databases such as PubMed and ScienceDirect. Chemical studies have presented beta-carboline alkaloids as the most active constituents, with harmalol, harmaline, and harmine being the latest and most studied among these naturally occurring alkaloids. The Peganum spp. extracts have shown neuroprotective, anticancer, antimicrobial, and antiviral effects. The extracts are also found effective in improving respiratory disorders (asthma and cough conditions), dermatoses, and knee osteoarthritis. Bioactivities and health-enhancing effects of Peganum spp. make it a potential candidate for the formulation of functional foods and pharmaceutical drugs. Nevertheless, adverse effects of this plant have also been described, and therefore new bioproducts need to be studied in depth. In fact, the design of new formulations and nanoformulations to control the release of active compounds will be necessary to achieve successful pharmacological and therapeutic treatments.

Abstract
Alzheimer's disease (AD), is the most common type of dementia primarily affecting the later years of life. Its prevalence is likely to increase in any aging population and will be a major burden on healthcare system by the mid of the century. Despite scientific and technological breakthroughs in the last 50 years, that have expanded our understanding of the disease on a system, cellular and molecular level, therapies that could stop or slow the progression of the disease are still unavailable. The Food and Drug Administration (FDA), has approved acetylcholinesterase (AChE) inhibitors (donepezil, galantamine, tacrine and rivastigmine) and glutamate receptor antagonist (memantine) for the treatment of AD. In this review we summarize the studies reporting phytocompounds and extracts from medicinal plants that show AChE inhibitory activities and could be of potential benefit in AD. Future research directions are suggested and recommendations made to expand the use of medicinal plants and their formulations to prevent, mitigate and treat AD.

An artificial series of macrocycles based on 4,4'-sulfonyldiphenol intermediate was synthesized using a multistep procedure involving oxidation of bisphenol sulfide, etherification of phenolic hydroxyl groups, and final ring closure with different diamines. Different chemical species having aromatic, heteroaromatic, and aliphatic characters were incorporated into macrocyclic frameworks in the final step of ring closure. This simple and easily executable synthetic strategy was applied to synthesize 15 macrocycles (5a-o) in excellent yields. Characterization of the synthesized products was achieved through well-known modern spectroscopic techniques such as IR, NMR, and Mass. Macrocycles 5m and 5n were found to show significant AChE inhibition with IC50 values of 76.9 ± 0.24 and 71.2 ± 0.77 μM, respectively. Macrocycle 5n was also found to be an active inhibitor of butyrylcholinesterase (BChE) with IC50 score of 55.3 ± 0.54 μM. Among others, macrocycle 5l cyclized with o-phenylenediamine demonstrated moderate inhibition with IC50 value of 81.1 ± 0.54 μM. Increasing interest in studying interactions of macrocycles with different enzymatic targets compelled us to design and synthesize sulfone-based macrocycles that might prove as highly potent class of biologically active compounds.

Same analytical method for both (bio)assay and zone isolation to identify/quantify bioactive compounds by quantitative nuclear magnetic resonance spectroscopy. J Chromatogr A 2020; 1628:461434. [PMID: 32822974 DOI: 10.1016/j.chroma.2020.461434] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 07/23/2020] [Accepted: 07/24/2020] [Indexed: 12/27/2022]
Abstract
Differing sensitivity is the main obstacle for a direct combination of HPTLC with NMR spectroscopy. A sufficient amount of the isolated compound zone must be provided by HPTLC for subsequent offline NMR detection (HPTLC//NMR). To fill the gap, a straightforward procedure was developed using the same analytical HPTLC system for both bioprofiling and isolation of bioactive zones from multicomponent mixtures. The HPTLC-effect-directed analysis (EDA) revealed several bioactive compounds in five botanical extracts, i.e. Salvia officinalis, Thymus vulgaris and Origanum vulgare, all Lamiaceae, and peels of red and green apples (Jonagored and Granny Smith, respectively), both Rosaceae. A tricky case study was designed to show how to deal with potentially coeluting bioactive structural isomers, e.g., ursolic (UA), oleanolic (OA) and betulinic acids (all C30H48O3), which are most difficult to identify and assign. A multipotent bioactive HPTLC zone showed the same hRF value and mass signal in HPTLCHRMS, though containing the coeluting structural isomers UA and OA. After zone isolation from the HPTLC plate, first the 1H NMR spectrum allowed to distinguish distinct allylic H-18 protons, i.e. 2.20 ppm for UA and 2.85 ppm for OA, and at the same time, to quantify the two isomers by using the PUlse Length-based CONcentration methodology (HPTLC//1H qNMR-PULCON). In case of a partial overlap of the diagnostic signal with that of the matrix, results were corroborated with those obtained by using the 1H deconvoluted or 2D 1H-13C Heteronuclear Single Quantum Coherence spectra. The comparison of the quantitative results showed a good correlation (R2 = 0.9718) between the two orthogonal methods HPTLC-Vis and HPTLC//1H qNMR-PULCON. A sufficient zone isolation from the HPTLC plate (mean isolation rate of 82%) for both UA and OA (0.27 - 4.67 mM) was achieved for HPTLC//qNMR, comparing the isolated bioactive compound zone with the respective zone in the botanical extract via HPTLC-Vis densitometry. The HPTLC-EDA-Vis//1H qNMR-PULCON procedure for bioprofiling and quantification/identification/confirmation of bioactive compounds in botanical extracts is considered as straightforward, eco-friendly (only 16 mL solvent required), simple (NMR calibration used over weeks) and reliable new alternative to the status quo of bioactivity-guided fractionation.

Abstract
BACKGROUND Peganum harmala L. is a medicinal herb extensively used in traditional Chinese medicine (TCM). So far, relevant reports on the toxicity of Peganum harmala L. seeds (PHS) are hardly available. Especially, we still know little about the in vivo mechanism for PHS toxicity. This study aims to evaluate the toxicity effects of PHS in Caenorhabditis elegans (C. elegans), investigate the possible mechanism of the toxicity effects of PHS, and provide reference for the pharmacological research of PHS. METHODS In the present study, the C. elegans was exposed to 0.25, 0.50, 1.00 mg/mL of PHS in nematode growth medium (NGM) at 22 °C in the presence of food. Lethality, lifespan, growth, reproduction, and locomotion behavior assays were performed to evaluate the toxicity effects of PHS in C. elegans. We then determined the mechanism of the toxicity effect of PHS by quantitative real-time polymerase chain reaction (qRT-PCR), acetylcholinesterase (AChE) activity assay, and oxidative stress resistance assays. The main components of PHS were detected by high performance liquid chromatography (HPLC). RESULTS Compared with the control group, the lethality of C. elegans was significantly increased when they were exposed to the ethanol extract of PHS at 0.25, 0.50 and 1.00 mg/mL (P < 0.01), and the mean lifespan was significantly decreased (P < 0.01). We also observed that PHS exposure could induce the toxicity on body length, brood size, and locomotion behavior. CONCLUSION Our study shows that the ethanol extract of PHS exerts obvious toxic effects on C. elegans, which would provide new ideas and methods for the biological evaluation of the toxicity of Chinese medicinal materials.

Abstract
Microorganisms and plants can be important sources of many compounds with potential pharmaceutical applications. Extraction of these matrices is one of the ways of identifying the presence of inhibitory active substances against enzymes whose high activity leads to serious human diseases including cancer, Parkinson's or Crohn's diseases. The isolation and purification of inhibitors are time-consuming and expensive steps in the analysis of the crude extract and therefore, it is necessary to find a fast, efficient, and inexpensive method for screening extracts of interest. TLC-Bioautography combines the separation of the extract on a thin layer with its subsequent biological analysis. TLC-Bioautography methods have been developed for several classes of enzymes including oxidoreductases, hydrolases and isomerases, and there is a potential for developing functional methods for other classes of enzymes. This review summarizes known TLC-Bioautography methods and their applications for determining the presence of enzyme inhibitors in extracts and compares the effectiveness of different methodological approaches. It also indicates the current state and perspective of the development of TLC-Bioautography and its possible future applications.

Neuroprotective potential of Ayahuasca and untargeted metabolomics analyses: applicability to Parkinson's disease. JOURNAL OF ETHNOPHARMACOLOGY 2020; 255:112743.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Ayahuasca is a tea produced through decoction of Amazonian plants. It has been used for centuries by indigenous people of South America. The beverage is considered to be an ethnomedicine, and it is traditionally used for the treatment of a wide range of diseases, including neurological illness. Besides, some scientific evidence suggests it may be applicable to Parkinson's disease (PD) treatment. Thus, Ayahuasca deserves in depth studies to clarify its potential role in this disease. AIM OF THE STUDY This study aimed to use an untargeted metabolomics approach to evaluate the neuroprotective potential of the Ayahuasca beverage, the extracts from its matrix plants (Banisteriopsis caapi and Psychotria viridis), its fractions and its main alkaloids on the viability of SH-SY5Y neuroblastoma cells in an in vitro PD model. MATERIAL AND METHODS The cytotoxicity of Ayahuasca, crude extracts, and fractions of B. caapi and P. viridis, as well as neuroprotection promoted by these samples in a 6-hydroxydopamine (6-OHDA)-induced neurodegeneration model, were evaluated by the MTT assay at two time-points: 48 h (T1) and 72 h (T2). The main alkaloids from Ayahuasca matrix plants, harmine (HRE) and N,N-dimethyltryptamine (DMT), were also isolated and evaluated. An untargeted metabolomics approach was developed to explore the chemical composition of samples with neuroprotective activity. Ultra-Performance Liquid Chromatography coupled to Electrospray Ionisation and Time-of-Flight (UPLC-ESI-TOF) metabolome data was treated and further analysed using multivariate statistical analyses (MSA): principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). The metabolites were dereplicated using the Dictionary of Natural Products and an in house database. The main alkaloids were also quantified by UPLC-MS/MS. RESULTS The samples did not cause cytotoxicity in vitro and three of samples intensely increased cell viability at T1. The crude extracts, alkaloid fractions and HRE demonstrated remarkable neuroprotective effect at T2 while the hydroalcoholic fractions demonstrated this neuroprotective effect at T1 and T2. Several compounds from different classes, such as β-carbolines and monoterpene indole alkaloids (MIAs) were revealed correlated with this property by MSA. Additionally, a total of 2419 compounds were detected in both ionisation modes. HRE showed potent neuroprotective action at 72 h, but it was not among the metabolites positively correlated with the most efficacious neuroprotective profile at either time (T1 and T2). Furthermore, DMT was statistically important to differentiate the dataset (VIP value > 1), although it did not exhibit sufficient neuroprotective activity by in vitro assay, neither a positive correlation with T1 and T2 neuroprotective profile, which corroborated the MSA results. CONCLUSION The lower doses of the active samples stimulated neuronal cell proliferation and/or displayed the most efficacious neuroprotection profile, namely by preventing neuronal damage and improving cell viability against 6-OHDA-induced toxicity. Intriguingly, the hydroalcoholic fractions exhibited enhanced neuroprotective effects when compared to other samples and isolated alkaloids. This finding corroborates the significance of a holistic approach. The results demonstrate that Ayahuasca and its base plants have potential applicability for PD treatment and to prevent its progression differently from current drugs to treat PD.

Abstract
Natural products have extensively contributed toward the discovery of new leads for Alzheimer's disease. During our search for new inhibitors of cholinesterase enzymes from natural sources, the ethyl acetate (EtOAc) extract of Rumex abyssinicus Jacq was identified as a dual cholinesterase inhibitor with IC50 values of 2.7 and 11.4 μg/mL against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), respectively. The phytochemical investigation of the EtOAc extract has resulted in isolation of four anthraquinones, namely, helminthosporin, emodin, chrysophanol, and physcion, amongst which the helminthosporin has been isolated for the first time from Rumex sp. All isolated secondary metabolites have displayed significant inhibition of EeAChE with IC50 values of 2.63, 15.21, 33.7, and 12.16 μM, respectively. In addition, the helminthosporin was also found to inhibit BChE with an IC50 value of 2.99 μM. The enzyme kinetic study has indicated that helminthosporin inhibits AChE and BChE in a noncompetitive manner with k i values of 10.3 and 12.3 μM, respectively. The results of molecular modeling and propidium iodide displacement assay have revealed that helminthosporin occupies the peripheral anionic site of the active site gorge of AChE. In the PAMPA-BBB permeability assay, helminthosporin was found to possess high BBB permeability (P e = 6.16 × 10-6 cm/s). In a nutshell, helminthosporin has been identified as a brain permeable dual cholinesterase inhibitor, and thus its further synthetic exploration is warranted for optimization of its potency.

Subchronic toxicity and concomitant toxicokinetics of long-term oral administration of total alkaloid extracts from seeds of Peganum harmala Linn: A 28-day study in rats. JOURNAL OF ETHNOPHARMACOLOGY 2019; 238:111866.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Peganum harmala Linn, in which the most abundant active compounds are harmaline and harmine, have been widely used as a traditional medicine in various countries to treat a broad spectrum of diseases including asthma, cough, depression, Parkinson's and Alzheimer's diseases. However, few studies on long-term or subchronic toxicity of seeds of P. harmala were reported after overdose. AIM OF THE STUDY To investigate the subchronic toxicity and concomitant toxicokinetics of total alkaloid extracts from seeds of P. harmala (TAEP) after oral administration for four weeks in rats. MATERIALS AND METHODS The subchronic toxicity and concomitant toxicokinetics of TAEP were evaluated after 28-day oral administration in rats at daily dose levels of 15, 45, and 150 mg/kg. The signs of toxicity and mortality were monitored and recorded daily. The body weight and average food consumption were measured weekly. The analyses of hematology, biochemistry, urine, relative organ weights and histopathology were conducted at the termination of treatment and recovery phase. For concomitant toxicokinetics study, the plasma toxicokinetic parameters, tissue distribution, and excretion of predominant ingredients harmaline and harmine in TAEP and metabolites harmalol and harmol were tested. RESULTS Following initial repeated exposure to high-dose (150 mg/kg/day) of TAEP excitotoxic reaction, such as tremor, was observed, but tolerated on the fourth day after multiple dosing. The significant alterations in blood glucose and lipid metabolism in liver were observed, but recovered after four weeks of drug withdrawal. The no-observed-adverse-effect level (NOAEL) of TAEP was considered to be 45 mg/kg/day under the present study conditions. There were no significant gender differences in most indexes of subchronic toxicity throughout the experimental period with the exception of food consumption and body weight. In concomitant toxicokinetics study, the alterations of dynamic characteristic for harmaline, harmine and metabolite harmol after multiple oral administration at three doses had been observed. Harmaline, harmine and metabolites harmalol and harmol were widely distributed in organs and there was no accumulation in the tissues examined. The reduction of harmaline and metabolite harmalol in brain after multiple dosing at dose of 150 mg/kg might be closely related to the tremor tolerance. The main excretory pathway for metabolites harmalol and harmol was urinary excretion via kidney. CONCLUSIONS The results revealed that TAEP at doses of 15 and 45 mg/kg/day in rats might be safe. Excitotoxic reaction such as tremor occurred initially at dose of 150 mg/kg/day, however, the toxicity was tolerant and reversible. In addition, harmaline and harmine in TAEP had a quick absorption into blood and metabolized to harmalol and harmol, and there was no drug accumulation in the detected tissues. Further studies should be investigated to clarify the mechanisms of tremor tolerance and neurotoxicity of TAEP.

Azadniya E, Morlock GE. Automated piezoelectric spraying of biological and enzymatic assays for effect-directed analysis of planar chromatograms. J Chromatogr A 2019; 1602:458-466. [PMID: 31153601 DOI: 10.1016/j.chroma.2019.05.043] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2019] [Revised: 05/22/2019] [Accepted: 05/23/2019] [Indexed: 12/14/2022]
Abstract
Bioanalytical questions are more and more solved by bioassays directly in situ the planar separation. If compared to chemical derivatization in situ, several reagent applications on the same chromatogram make the workflow for enzymatic and biological assays more complex. Hence, if compared to piezoelectric spraying of chemical derivatization reagents, an assay transfer to the piezoelectric spraying technique was much more challenging. Important aspects were investigated, i.e., plate pre-wetting, spraying nozzle type and applied volumes for microorganism suspension as well as enzyme and substrate-chromogenic solutions. Finally, with the newly developed piezoelectric spraying procedures for the application of biological (Aliivibrio fischeri) and enzymatic (acetyl- and butyrylcholinesterase) assays, several obstacles of the state-of-the-art automated immersion were avoided such as the (1) required high volumes of solutions, (2) tailing of highly water-soluble zones upon slow plate withdrawal, (3) zone distortion or shift observed after previous buffer salt applications or long/slow immersion times/speeds, (4) gradual inactivation of the enzyme solution along with its ongoing re-use, and (5) lack of covering the whole plate surface. The benchmarking of both techniques also showed that simplicity remains the key argument for immersion. As proof of concept, piezoelectrically sprayed autograms were compared with those of immersion, by taking the example of Peganum harmala (P. h.) seed extract. The plate background and thus homogeneity of the applied solutions were found to be almost comparable. Three bands among the pronounced fluorescent bands were responsible for the most antibacterial activity of P. h. seed extract in the A. fischeri bioassay and were also inhibiting the AChE. These AChE and three further BChE inhibitors were detected, whereby the AChE inhibition was twice as strong as the BChE inhibition. By their in situ HRMS spectra, the active zones in the P. h. seed extract were assigned to be the AChE-inhibiting β-carboline alkaloids, harmine, harmaline and ruine, as well as the BChE-inhibiting quinazoline alkaloids, vasicine and deoxyvasicine, and the β-carboline alkaloid harmol. For the first time, the found inhibitors were calculated equivalently to the well-known ChE-inhibitor physostigmine, and thus, piezoelectric spraying was proven to be suited for quantifications.

Abstract
An orthogonal two dimensional analysis method based on high performance liquid chromatography (HPLC) separation and electrospray ionization-ion mobility spectrometry (ESI-IMS) detection was developed for the analysis of alkaloid compounds from Peganum harmala L. seeds. Reverse phase (RP) and hydrophilic interaction chromatography (HILIC) were compared for the most optimal performance using three different chromatographic columns. The experimental results suggest that HILIC mode is a better option for combining with the ESI-IMS system for higher sensitivity and ease in hyphenating. Under optimized conditions, alkaloids from different extraction phases were determined by means of the established HPLC-IMS method. More compounds from Peganum harmala L. seed extracts were differentiated on the HPLC-ESI-IMS system by their retention time and drift time than by HPLC or ESI-IMS alone, and thirteen alkaloids were tentatively identified based on m/z and fragment ions using ultra-high-performance liquid chromatography tandem mass-spectrometry (UPLC-MS/MS). Hence, our results indicate that this method can be considered to be advantageous over traditional absorbance detection methods for resolving complex mixtures because of complementary separation steps, elevated peak capacity, and higher sensitivity.

Abstract
A rare walnut variant with a red seed coat (pellicle) was examined for alterations in its phenolic profile during development. The red-walnut (RW) pellicle was compared with two commonly colored walnut varieties: 'Lara' (brown) and 'Fernor' (light brown). Furthermore, the activities of selected enzymes of the phenylpropanoid- and flavonoid-related pathways and the relative expressions of the structural genes phenylalanine ammonia lyase ( PAL) and anthocyanidin synthase ( ANS) were examined in the pellicles of the three varieties. In the pellicles of the RWs, phenylalanine ammonia lyase (PAL) activity and related PAL expression was most pronounced in August, about one month before commercial maturity, suggesting a high synthesis rate of phenolic compounds at this development stage. The most pronounced differences between the red and light- and dark-brown varieties were the increased PAL activity, PAL expression, and ANS expression in RWs in August. The vibrant color of the RW pellicle is based on the presence of four derivatives of cyanidin- and delphinidin-hexosides.

Abstract
A nuclear magnetic resonance- (NMR-) based metabolomics method was used to identify differential metabolites of methanol extracts obtained from six parts of Peganum harmala L. (P. harmala), namely, the root, stem, leaf, flower, testa, and seed. Two multivariate statistical analysis methods, principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA), were combined to clearly distinguish among the P. harmala samples from the six different parts. Eleven differential components were screened by the PLS-DA loading plot, and the relative contents were calculated by univariate analysis of variance. Chemometric results showed significant differences in the metabolites of the different parts of P. harmala. The seeds contained large amounts of harmaline, harmine, and vasicine compared to other organs. The acetic acid, proline, lysine, and sucrose contents of the roots were significantly higher than those of the other parts. In the testa, the vasicine, asparagine, choline, and 4-hydroxyisoleucine contents were clearly dominant. The obtained data revealed the distribution characteristics of the metabolomes of the different P. harmala parts and provided fundamental knowledge for the rational development of its medicinal parts.

Abstract
With the recent research advances in molecular biology and technology, multiple credible hypotheses about the progress of Alzheimer's disease (AD) have been proposed; multi-target drugs have emerged as an innovative therapeutic approach for AD. Current clinical therapy for AD patients is mainly palliative treatment targeting acetylcholinesterase (AChE). Inhibition of phosphodiesterase 5A (PDE5A) has recently been validated as a potentially novel therapeutic approach for Alzheimer's disease (AD). In this work, series of new compounds were designed, synthesized and evaluated as dual cholinesterase and PDE5A inhibitor. Biological results revealed that some of these compounds display good biological activities against AChE with IC50 values about 44.67-169.80nM (donepezil IC50 50.12nM). Notably, compound 12 presented potent activities against PDE5A with IC50 values about 50μM (sildenafil IC50 12.59μM), and some of these compounds showed low cell toxicity to A549 cells in vitro.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aerial parts of Peganum harmala Linn (APP) is used as traditional medical herb for treatment of forgetfulness in Uighur medicine in China. But, the active ingredients and underlying mechanisms are unclear. AIM OF THE STUDY The present study was undertaken to investigate the improvement effects of extract and alkaloid fraction from APP on scopolamine-induced cognitive dysfunction and to elucidate their underlying mechanisms of action, and to support its folk use with scientific evidence, and lay a foundation for its further researches. MATERIALS AND METHODS The acetylcholinesterase (AChE) inhibitory activities of extract (EXT), alkaloid fraction (ALK) and flavonoid fraction (FLA) from APP were evaluated in normal male C57BL/6 mice. The anti-amnesic effects of EXT and ALK from APP were measured in scopolamine-induced memory deficits mice by the Morris water maze (MWM) tasks. The levels of biomarkers, enzyme activity and protein expression of cholinergic system were determined in brain tissues. RESULTS The AChE activity was significantly decreased and the content of neurotransmitter acetylcholine (ACh) was significantly increased in normal mice cortex and hippocampus by treatment with donepezil at dosage of 8mg/kg, EXT at dosages of 183, 550, 1650mg/kg and ALK at dosages of 10, 30, 90mg/kg (P<0.05), and the AChE activity and the content of ACh were not significantly changed in cortex and hippocampus after treatment with FLA at dosages of 10, 30, 90mg/kg (P>0.05). In the MWM task, scopolamine-induced a decrease in both the swimming time within the target zone and the number of crossings where the platform had been placed were significantly reversed by treatment with EXT at dosages of 550, 1650mg/kg and ALK at dosages of 30, 90mg/kg (P<0.05). Moreover, the activity and protein expression of AChE was significantly decreased and the content of neurotransmitter ACh was significantly increased in cerebral cortex of scopolamine-induced mice by treatment with EXT at dosages of 183, 550, 1650mg/kg and ALK at dosages of 10, 30, 90mg/kg (P<0.05), compared with scopolamine-treated group. CONCLUSIONS EXT and ALK from APP exert beneficial effect on learning and memory processes in mice with scopolamine-induced memory impairment. APP is an effective traditional folk medicine and the ALK fraction is proved to be the main effective components for the treatment of forgetfulness. The ALK may be valuable source for lead compounds discovery and drug development for treatment of memory impairment such as in Alzheimer's disease.

Li S, Cheng X, Wang C. A review on traditional uses, phytochemistry, pharmacology, pharmacokinetics and toxicology of the genus Peganum. JOURNAL OF ETHNOPHARMACOLOGY 2017; 203:127-162. [PMID: 28359849 DOI: 10.1016/j.jep.2017.03.049] [Citation(s) in RCA: 71] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Revised: 03/24/2017] [Accepted: 03/25/2017] [Indexed: 05/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plants of the genus Peganum have a long history as a Chinese traditional medicine for the treatment of cough, hypertension, diabetes, asthma, jaundice, colic, lumbago, and many other human ailments. Additionally, the plants can be used as an amulet against evil-eye, dye and so on, which have become increasingly popular in Asia, Iran, Northwest India, and North Africa. AIM OF THE REVIEW The present paper reviewed the ethnopharmacology, phytochemistry, analytical methods, biological activities, metabolism, pharmacokinetics, toxicology, and drug interaction of the genus Peganum in order to assess the ethnopharmacological use and to explore therapeutic potentials and future opportunities for research. MATERIALS AND METHODS Information on studies of the genus Peganum was gathered via the Internet (using Google Scholar, Baidu Scholar, Elsevier, ACS, Pudmed, Web of Science, CNKI and EMBASE) and libraries. Additionally, information was also obtained from some local books, PhD and MS's dissertations. RESULTS The genus Peganum has played an important role in traditional Chinese medicine. The main bioactive metabolites of the genus include alkaloids, flavonoids, volatile oils, etc. Scientific studies on extracts and formulations revealed a wide range of pharmacological activities, such as cholinesterase and monoamine oxidase inhibitory activities, antitumor, anti-hypertension, anticoagulant, antidiabetic, antimicrobial, insecticidal, antiparasidal, anti-leishmaniasis, antioxidant, and anti-inflammatory. CONCLUSIONS Based on this review, there is some evidence for extracts' pharmacological effects on Alzheimer's and Parkinson's diseases, cancer, diabetes, hypertension. Some indications from ethnomedicine have been confirmed by pharmacological effects, such as the cholinesterase, monoamine oxidase and DNA topoisomerase inhibitory activities, hypoglycemic and vasodilation effects of this genus. The available literature showed that most of the activities of the genus Peganum can be attributed to the active alkaloids. Data regarding many aspects of the genus such as mechanisms of actions, metabolism, pharmacokinetics, toxicology, potential drug interactions with standard-of-care medications is still limited which call for additional studies particularly in humans. Further assessments and clinical trials should be performed before it can be integrated into medicinal practices.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2015; 22:1088-1095. [PMID: 26547531 DOI: 10.1016/j.phymed.2015.08.005] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2015] [Revised: 08/04/2015] [Accepted: 08/12/2015] [Indexed: 06/05/2023]
Abstract
BACKGROUND The aerial parts of Peganum harmala L. (APP) is a well-known and effective herbal medicine in China, and has been commonly used for treating various ailments, including cough and asthma. OBJECTIVES To evaluate the antitussive, expectorant, and bronchodilating effects of the quinazoline alkaloids (±)-vasicine (VAS), deoxyvasicine (DVAS) (both isolated from the alkaloid fraction of APP) and (±)-vasicinone (VAO) (synthesized from VAS). METHODS The three quinazoline alkaloids were tested as antitussive on cough models in mice and guinea pigs. VAO was synthesized from VAS via the oxidation of hydrogen peroxide. VAS, VAO, and DVAS were orally administered at dosages of 5, 15, and 45 mg/kg. Cough in these models was induced by ammonia, capsaicin, and citric acid. Phenol red secretion experiments in mice were performed to evaluate the expectorant activity of the alkaloids. Bronchodilating effects were evaluated by using a bronchoconstrictive induced by acetylcholine chloride and histamine in guinea pigs. RESULTS In antitussive tests, VAS, VAO, and DVAS significantly inhibited coughing frequency and prolonged the cough latency period in animals. At the highest doses tested (45 mg/kg), they showed antitussive activities similar to codeine phosphate (30 mg/kg) in mice and guinea pigs. Expectorant evaluation showed that VAS, VAO, and DVAS could significantly increase phenol red secretion in mice by 0.54-, 0.79- and 0.97-fold, by 0.60-, 0.99-, and 1.06-fold, and by 0.46-, 0.73-, and 0.96-fold, respectively, at dosages of 5, 15, and 45 mg/kg compared with the control (0.5% CMC-Na, 20 ml/kg). Ammonium chloride at 1500 mg/kg increased phenol red secretion in mice by 0.97-fold compared with the control. Bronchodilation tests showed that VAS, VAO, and DVAS prolonged the pre-convulsive time for 28.59%, 57.21%, and 29.66%, respectively, at a dose of 45 mg/kg in guinea pigs, whereas aminophylline prolonged the pre-convulsive time by 46.98% compared with pretreatment. CONCLUSIONS Quinazoline alkaloids VAS, VAO, and DVAS have significant antitussive, expectorant, and bronchodilating activities. VAS, VAO, and DVAS are the active ingredients in APP, which can be used to treat respiratory disease.

Abstract
Bioactivity-guided fractionation was used to determine the cytotoxic alkaloids from the toxic plant Peganum harmala. Two novel indole alkaloids, together with ten known ones, were isolated and identified. The novel alkaloids were elucidated to be 2-(indol-3-yl)ethyl-α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside (2) and 3-hydroxy-3-(N-acetyl-2-aminoethyl)-6-methoxyindol-2-one (3). The cytotoxicity against human leukemia cells was assayed for the alkaloids and some of them showed potent activity. Harmalacidine (compound 8, HMC) exhibited the highest cytotoxicity against U-937 cells with IC50 value of 3.1 ± 0.2 μmol/L. The cytotoxic mechanism of HMC was targeting the mitochondrial and protein tyrosine kinase signaling pathways (PTKs-Ras/Raf/ERK). The results strongly demonstrated that the alkaloids from Peganum harmala could be a promising candidate for the therapy of leukemia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Seeds of Peganum harmala Linn are traditionally used as folk medical herb in Uighur medicine in China to treat disorders of hemiplegia and amnesia. Previously studies have proved that dominating alkaloids in P. harmala show significant inhibitory activities on the cholinesterase. AIM OF THE STUDY The aim of the present study is to isolate trace ingredients from seeds of P. harmala and evaluate its inhibitory activities on acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). MATERIALS AND METHODS For sake of screening effective cholinesterase inhibitors, trace compounds were isolated from seeds of P. harmala through a bioassay-guided fractionation and their structures were determined via detailed spectral analysis. The inhibitory activities on AChE and BChE were assessed using an improved Ellman method by UPLC-ESI-MS/MS to determine the common final product choline. RESULTS The activity-guided fractionation led to the isolation of two new alkaloids 2-aldehyde-tetrahydroharmine (10), 2-carboxyl-3,4-dihydroquinazoline (19), one syringin structure analog 1-O-β-D-xylopyranose sinapyl alcohol (22), and along with 19 known compounds. Compounds acetylnorharmine (6), harmic acid methy ester (7), harmine N-oxide (13), 6-methoxyindoline (14), syringin (21) were first found from genus Peganum and compounds 3-hydroxylated harmine (4), 1-hydroxy-7-methoxy-β-carboline (5) were new natural products. The results showed that the 2-aldehyde-tetrahydroharmine (10) has a potential inbibitive effect on both AChE and BChE with IC50 values of 12.35 ± 0.24 and 5.51 ± 0.33 µM, respectively. Deoxyvasicine (15) and vasicine (16) showed the strongest BChE inhibitory activity with IC50 values of 0.04 ± 0.01 and 0.1 ± 0.01 µM. The analysis of the structure-activity relationship indicated that the saturation of pyridine ring and the presence of substitution at indole ring, C-1, C-3, C-7 and N-2, for β-carbolines, were essential for effective inhibition of both AChE and BChE and the five-membered ring between C-2 and N-3 as well as the substituent groups sited at C-4 and C-9, for quinazolines, were important to both the AChE/BChE-inhibitory activity. CONCLUSIONS Bioassay-guided fractionation has led to the isolation of AChE and BChE inhibitors from the seeds of P. harmala. These results are in agreement with the traditional uses of the seeds of P. harmala.

Abstract
Intramolecular cyclization of the heteroenyne-allene, 2-((phenylimino)methyleneamino)-benzonitrile (1) in the presence of HCl to produce 2-chloro-3-phenyl-4(3H)-quinazoliniminium chloride (Qz) involves the formation of two new bonds: a C-Cl bond and a C-N bond. We propose five pathways for this reaction. Four of these pathways involve chloride capture to form the C-Cl bond prior to the intramolecular nucleophilic attack to form the C-N bond, while one pathway involves ring closure to form the C-N bond prior to C-Cl bond formation. All calculations were carried out at B3LYP and MP2 levels of theory and employed the 6-311G* basis set. The solvent effects were considered using a Polarized Continuum Model with dichloromethane as the solvent. The calculations at both levels show that the mechanism involves initial protonation of 1, preferentially at Nα to give 2 which rapidly captures the chloride ion to form 5. This intermediate is protonated at the -CN group to form 8ROT, which then tautomerizes to its more stable isomer 9ROT. The latter undergoes intramolecular nucleophilic attack from Nβ to the protonated -CN group to form the cyclized intermediate 12, which tautomerizes to its most stable isomer 13. The coordination of Cl(-) ion present in the solution with 13 gives the final product Qz.

A phytochemical study on the methanol extracts from the seeds of Peganum harmala L. led to a new quizonaline alkaloid (S)-vasicinone-1-O-β-d-glucopyranoside (1) and four known ones, (R)-vasicinone-1-O-β-d-glucopyranoside (2), (S)-vasicinone (3), vasicine (4), and deoxyvasicinone (5). Their structures were elucidated by spectroscopic analysis including IR, HR-ESI-MS, 1D and 2D NMR, and specific rotation as well as by comparison of the data with those in the literature. All of the alkaloids were screened for antiproliferative activity against human gastric cancer cells MCG-803 with MTT method. Compounds 1 and 3 exhibited moderate inhibitory activity.

Abstract
Vasicine (VAS), a potential natural cholinesterase inhibitor, exhibited promising anticholinesterase activity in preclinical models and has been in development for treatment of Alzheimer’s disease. This study systematically investigated the in vitro and in vivo metabolism of VAS in rat using ultra performance liquid chromatography combined with electrospray ionization quadrupole time-of-flight mass spectrometry. A total of 72 metabolites were found based on a detailed analysis of their 1H- NMR and 13C NMR data. Six key metabolites were isolated from rat urine and elucidated as vasicinone, vasicinol, vasicinolone, 1,2,3,9-tetrahydropyrrolo [2,1-b] quinazolin-3-yl hydrogen sulfate, 9-oxo-1,2,3,9-tetrahydropyrrolo [2,1-b] quinazolin-3-yl hydrogen sulfate, and 1,2,3,9-tetrahydropyrrolo [2,1-b] quinazolin-3-β-D-glucuronide. The metabolic pathway of VAS in vivo and in vitro mainly involved monohydroxylation, dihydroxylation, trihydroxylation, oxidation, desaturation, sulfation, and glucuronidation. The main metabolic soft spots in the chemical structure of VAS were the 3-hydroxyl group and the C-9 site. All 72 metabolites were found in the urine sample, and 15, 25, 45, 18, and 11 metabolites were identified from rat feces, plasma, bile, rat liver microsomes, and rat primary hepatocyte incubations, respectively. Results indicated that renal clearance was the major excretion pathway of VAS. The acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of VAS and its main metabolites were also evaluated. The results indicated that although most metabolites maintained potential inhibitory activity against AChE and BChE, but weaker than that of VAS. VAS undergoes metabolic inactivation process in vivo in respect to cholinesterase inhibitory activity.

In vivo evaluation of the antitussive, expectorant and bronchodilating effects of extract and fractions from aerial parts of Peganum harmala linn. JOURNAL OF ETHNOPHARMACOLOGY 2015; 162:79-86. [PMID: 25557031 DOI: 10.1016/j.jep.2014.12.046] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2014] [Revised: 12/02/2014] [Accepted: 12/23/2014] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aerial parts of Peganum harmala Linn (APP) is used as traditional medical herb in Uighur medicine in China, and it is traditionally used for treatment of cough and asthma.The aim of the present study is to evaluate the antitussive, expectorant and bronchodilating effects of extract and fractions (alkaloids and flavonoids) from APP, and to support its folk use with scientific evidence, and lay a foundation for its further researches. MATERIALS AND METHODS APP was extracted with 50% ethanol by reflux, extracts were concentrated in vacuum to afford total extract of APP (EXT). EXT was separated to provide alkaloid fraction (ALK) and flavonoid fraction (FLA) by macroporous resin. Antitussive evaluations were carried out with cough models in mice and guinea pigs induced by ammonia liquor, capsaicin, and citric acid. Phenol red secretion experiments in mice were performed to evaluate the expectorant activity. Bronchodilating activities were evaluated with a bronchoconstrictive challenge induced by acetylcholine chloride and histamine in guinea pigs. RESULTS In all the three antitussive tests, the EXT and ALK could significantly inhibit the frequency of cough, and prolong the cough latent period in animals. High dose of EXT (1650 mg/kg) and ALK (90 mg/kg) in mice and in guinea pigs created therapeutic activities as good as that of codeine phosphate (30 mg/kg). EXT could significantly increase phenol red secretion in mice for 0.64, 1.08 and 1.29 fold averagely at dosages of 183, 550, and 1650 mg/kg, ALK for 0.63, 0.96, 1.06 fold averagely at dosages of 10, 30, and 90 mg/kg, and ammonium chloride (1500 mg/kg, standard expectorant drug) for 0.97 fold, comparing with control group. Aminophylline could dramatically prolong the preconvulsive time for 162.28% in guinea pigs, EXT for 67.34%, 101.96% and 138.00% at dosages of 183, 550, and 1650 mg/kg, ALK for 55.47%, 97.74% and 126.77% at dosages of 10, 30, and 90 mg/kg, and FLA for 84.69%, 95.94% and 154.52% at dosages of 10, 30, and 90 mg/kg, comparing with pretreatment. CONCLUSIONS APP is an effective traditional folk medicine for the treatment of cough with potent antitussive, expectorant and bronchodilating activities. The alkaloid fraction is proved to be the most effective components of APP. The alkaloids from APP may be valuable lead compounds for drug development of respiratory diseases.

Abstract
INTRODUCTION Alzheimer's disease (AD) has increased at an alarming rate and is now a worldwide health problem. Inhibitors of acetylcholinesterase (AChE) leading to inhibition of acetylcholine breakdown constitute the main therapeutic strategy for AD. Psoralen was investigated as inhibitor of AChE enzyme in an attempt to explore its potential for the management of AD. MATERIALS AND METHODS Psoralen was isolated from powdered Psoralea corylifolia fruits. AChE enzyme inhibitory activity of different concentrations of psoralen was investigated by use of in vitro enzymatic and molecular docking studies. Further, the enzyme kinetics were studied using Lineweaver-Burk plot. RESULTS Psoralen was found to inhibit AChE enzyme activity in a concentration-dependent manner. Kinetic studies showed psoralen inhibits AChE in a competitive manner. Molecular docking study revealed that psoralen binds well within the binding site of the enzyme showing interactions such as π-π stacking and hydrogen bonding with residues present therein. CONCLUSION The result of AChE enzyme inhibitory activity of the psoralen in this study is promising. It could be further explored as a potential candidate for further development of new drugs against AD.
