[PMID: 38693737 DOI: 10.2174/0109298665305131240404072542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 03/17/2024] [Accepted: 03/21/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND Cancer remains a global burden, with increasing mortality rates. Current cancer treatments involve controlling the transcription of malignant DNA genes, either directly or indirectly. DNA exhibits various structural forms, including the G-quadruplex (G4), a secondary structure in guanine-rich regions. G4 plays a crucial role in cellular processes by regulating gene expression and telomerase function. Researchers have recently identified G4-stabilizing binding agents as promising anti-cancer compounds. Additionally, peptides have emerged as effective anticancer pharmaceuticals due to their ability to form multiple hydrogen bonds, electrostatic interactions, and van der Waals forces. These properties enable peptides to bind to specific areas of DNA chains selectively. However, despite these advancements, designing G4-binding peptides remains challenging due to a lack of comprehensive information. OBJECTIVE In our present study, we employed an in silico fragment-based approach to design G4- binding peptides. This innovative method combines machine learning classification, molecular docking, and dynamics simulation. METHODS AutoDock Vina and Gromacs performed molecular docking and MD simulation, respectively. The machine learning algorithm was implemented by Scikit-learn. Peptide synthesis was performed using the SPPS method. The DNA binding affinity was measured by applying spectrophotometric titration. RESULTS As a result of this approach, we identified a high-scoring peptide (p10; sequence: YWRWR). The association constant (Ka) between p10 and the ctDNA double helix chain was 4.45 × 105 M-1. Molecular modeling studies revealed that p10 could form a stable complex with the G4 surface. CONCLUSION The obtained Ka value of 4.45 × 105 M-1 indicates favorable interactions. Our findings highlight the role of machine learning and molecular modeling approaches in designing new G4-binding peptides. Further research in this field could lead to targeted treatments that exploit the unique properties of G4 structures.

[PMID: 38654943 PMCID: PMC11033537 DOI: 10.18502/ijpa.v19i1.15189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 01/25/2024] [Indexed: 04/26/2024]
Abstract
Background Trichomoniasis is one of the most common sexually transmitted infections worldwide. The growing concern of drug resistance of this infection has cautioned the need for new drug development. We evaluated the potential antiproliferative and apoptotic effect of α-pinene and tannic acid (TA) on Trichomonas vaginalis cells. In addition, the cytotoxicity of agents on Vero cells was investigated. Methods Trichomonas cells were axenically cultured in TYI-S-33 medium. In vitro antiproliferative activity of α-pinene, TA, and metronidazole was investigated against Trichomonas cells. The assays were carried out in triplicate using microtiter plate and trypan blue staining method. Annexin V/PI staining with flow cytometry was used to evaluate apoptosis induction. In addition, the cytotoxic effect was measured by MTT assay. Results α-Pinene and TA exhibited significant inhibition of the Trichomonas cells and the lowest IC50 values were 22.9 μg/ml and 140 μg/ml at 48 hours' incubation, respectively. The CC50 was found at 116 μg/ml for α-pinene and 473 μg/ml for TA, after 48 hours of treatment. The flow cytometry study demonstrated that the natural compounds induced apoptosis in Trichomonas cells. After 24 hours of treatment, the induction of apoptosis was 5.2% - 36.6% at concentrations of 3.9 - 62.5 μg/ml for α-pinene and TA induced-apoptosis was 6.1% - 53.8% at concentrations of 125-2000 μg/ml. Conclusion Although the results show the antiproliferative and apoptotic effect of α-pinene and TA on Trichomonas cells, in vivo studies are needed to further clarify the effects of these compounds.

[PMID: 38109132 DOI: 10.1080/07391102.2023.2294176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 11/25/2023] [Indexed: 12/19/2023]
Abstract
Alzheimer's disease (AD) is the most common cause of dementia worldwide and is classified as a neurodegenerative disorder. From a drug design perspective, natural products (NPs) are more drug-like and are highly compatible with biological systems compared to most synthetic libraries. NPs provide a more efficient and cost-effective approach to new drug discovery. However, the complexity of NPs makes their identification a challenging task. Chimgin, a bicyclic monoterpene with three chiral centers, exhibits a wide range of biological activity. Despite this, the exact structure of chimgin has remained unclear until now. In this study, we quantified the amount of chimgin in Ferula haussknechtii using analytical Reversed-phase high-pressure liquid chromatography equipped with photodiode array detector (RP-HPLC-PDA). Furthermore, we determined the absolute configuration of chimgin through electronic circular dichroism (ECD) spectroscopy and time-dependent density functional theory (TDDFT) calculations. Finally, we evaluated its inhibitory effect on AChE through in vitro and in silico studies. The extraction process yielded an output of 2.82 ± 0.10% with an exact amount of 0.62 ± 0.04 mg of chimgin per 100 g of plant. Based on the results of ECD and TDDFT calculation, the absolute configuration of chimgin was determined to be 1S, 2S, 4S. Chimgin exhibited an inhibitory effect on AChE with an IC50 of 37.43 µM and its mechanism of action was found to be competitive. HighlightsChimgin was isolated from the roots of Ferula haussknechtii.The amount of chimgin in the plant was determined by RP-HPLC-PDA.Its absolute configuration of chimgin was determined using ECD.In vitro acetylcholinesterase activity of the chimgin was evaluated.The docking and molecular dynamic simulation of chimgin was done.Communicated by Ramaswamy H.

[PMID: 37906119 DOI: 10.1002/cbdv.202301302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 10/26/2023] [Accepted: 10/29/2023] [Indexed: 11/02/2023]
Abstract
Ferulago bernardii Tomk & M. Pimen belongs to Apiaceae family. Various species of the Ferulago genus have antioxidant, anticholinesterase, cytotoxic, and antiproliferative effects. In this study, the essential oil of F. bernardii was extracted using the Clevenger apparatus. The essential oil compounds were identified using GC-MS/FID. The interaction between the essential oil and DNA strands was evaluated through spectrophotometric titration. The molecular mechanism of the interaction between the main components of the essential oil and different DNA strands was assessed using molecular dynamics simulation. Based on the results, 92.03±1.20 % of the essential oil consisted of α-pinene. Therefore, the essential oil could serve as a suitable source of α-pinene. α-pinene is a monoterpene hydrocarbon that has various effects, including anti-inflammatory, antioxidant, antimicrobial, and antitumor properties. The binding constant of the essential oil to DNA strands (Ka ) was determined to be 5.40±0.47×10-3 M-1 . Molecular dynamics simulation demonstrated that α-pinene could interact with AT and CG rich DNA strands and indirectly stabilize G-Quadruplex. Given the different applications for α-pinene and its high percentage in the essential oil, it is suggested that researchers pay more attention to F. bernardii in the pharmaceutical, cosmetic, and food industries.

Abstract
Background Ionizing radiation (IR) is widely used in the treatment of cancer in radiotherapy. One of the main concerns of patients with gastrointestinal cancers undergoing radiotherapy is the harmful side effects of IR on normal tissues. The liver, kidney, and duodenum are usually exposed to high doses of radiation in the treatment of some cancers in abdominal region radiotherapy. We aimed to assess the radioprotective effects of Malva sylvestris L. against IR damages to the abdominal region. Materials and methods This current study was conducted on 45 rats divided randomly into nine groups of five: A) negative control group, B) sham group, C) irradiation group, D) mallow treatment-1(200gr/kg), E) mallow treatment-2(400gr/kg), F) mallow treatment-3(600gr/kg), G) mallow treatment-4(200gr/kg) plus irradiation, H) mallow treatment-5(400gr/kg) plus irradiation, I) mallow treatment-6(600gr/kg) plus irradiation. Irradiation was performed with a 6Gy x-ray. Histopathological evaluations were performed 10 days after irradiation. Results The histopathological examination results confirmed that preventive therapy with the effective dose of mallow reduced the liver, kidney, and intestine damage induced by radiation. The dose of 400 mg/kg was more effective than other selected dose in improving the damage caused by irradiation in the studied tissues. Conclusion This study concludes that Malva sylvestris L. contributed to significant improvements in radiation-induced histological parameters of the liver and kidney and, to a lesser extent, in the intestine. These results collectively indicate that mallow is an effective radioprotective agent.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ferula gummosa Boiss., known in Persian as "Baridje," belongs to the Apiaceae family. All parts of this plant, especially the root, contain galbanum. Galbanum, the oleo-gum resin of F. gummosa, is one of the essential traditional herbal medicines in Iran, which is used as a tonic for epilepsy and chorea, memory enhancement, gastrointestinal diseases, and wound healing. AIM OF THE STUDY We investigated the toxicity, anticonvulsant effects, and molecular modeling of the essential oil (EO) distilled from the oleo-gum resin of F. gummosa. MATERIALS AND METHODS Gas chromatography-mass spectrometry was used to identify the EO components. The cytotoxicity of EO on HepG2 cell lines was assessed by the MTT method. Male mice were arranged as follows: negative control groups (sunflower oil (10 ml/kg, i.p.) or saline (10 ml/kg, p.o.)), EO groups (0.5, 1, 1.5, and 2.5 ml/kg, p.o.), and positive control groups (ethosuximide (150 mg/kg, p.o.) or diazepam (1.0 or 2 mg/kg, i.p.)). The motor coordination and neurotoxicity of EO were studied using the rota-rod test. Open-field, novel object recognition, and passive avoidance learning tests were used to investigate the effect of EO on locomotor activity and memory function. An acute pentylenetetrazole-induced seizure model was utilized to evaluate the anticonvulsant properties of the EO. The interaction of the EO main components with the GABAA receptor was investigated by coarse-grained molecular dynamics simulations. RESULTS β-pinene, sabinene, α-pinene, and ρ-cymene were the main components of EO. The IC50 of the EO at 24, 48, and 72 h was found to be 59.90, 12.96, and 3.93 μl/ml, respectively. No adverse effects were observed in memory, motor coordination, and locomotor activity in mice treated with EO. Administration of EO (1, 1.5, and 2.5 ml/kg) improved survival rates in mice receiving pentylenetetrazole (PTZ; to induce an epileptic seizure). Sabinene was able to bind to the binding site of benzodiazepines at the GABAA receptor. CONCLUSIONS Acute treatment with the EO of F. gummosa caused antiepileptic effects and could effectively increase the survival rate in PTZ-treated mice with no significant toxicity.

Abstract
Objectives Dental caries is one of the most prevalent human diseases worldwide. The disease initiates with bacterial adherence to the tooth surface followed by the formation of dental plaques. Mutans streptococci and Candida albicans are principal oral microorganisms involved in the initiation and development of dental caries. Phytochemicals have been shown to possess promising antimicrobial properties against a wide range of microorganisms and can be used for the prevention and treatment of dental caries. Herein, we reviewed literature on plants that are traditionally used for their antimicrobial properties or possess promising anticariogenic activity. We selected aerial parts of Scrophularia striata (S. striata) and galls of Quercus infectoria (Q. infectoria) and investigated their antimicrobial activity against cariogenic microorganisms. Methods Water soluble fractions were obtained from hydroalcoholic extracts of S. striata and Q. infectoria and their antimicrobial activity against Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), and Candida albicans (C. albicans) was evaluated separately and in combination. The extracts were then used for preparing an herbal mouthwash whose stability and tannic acid content were evaluated over 60 days. Results Q. infectoria gall extract possesses efficient antimicrobial activity that was synergistically enhanced in the presence of S. striata extract. Mouthwash prepared using these extracts showed desirable organoleptic characteristics, antimicrobial activity, and stability. Conclusion Extracts of S. striata and Q. infectoria galls can be used together for preparing dental products with effective anticariogenic properties. Our study highlights the importance of extensive pharmacological investigations when using herbal products alone or in combination with other chemical substances.

Abstract
Cancer disease is developing all over the world mainly in developing countries. We should learn more about DNA–ligand interactions to design new drugs that target biological activities like transcription, replication and translation of particular genes. To understand the mechanism of action and design-specific DNA binders, the evaluation of DNA–ligand interactions is critical. Novel barbituric acid derivatives based on (benzyloxy)benzaldehydes were synthesized and evaluated as DNA-binding agents. Among products, molecular docking studies revealed that 4j and 4m have the best interactions with the ctDNA via the minor groove binding. These results were approved by the quantum mechanics calculations. The interaction profiles of the selected compound (4j and 4m) with DNA were evaluated by UV–Visible titration. UV–Visible titration data confirm this interaction. According to the molecular modeling results, the Structure–Activity relationships for all synthesized barbituric acid derivatives were proposed. It was observed that N,N-dimethyl barbituric acid/4-hydroxybenzaldehyde derivatives have better DNA interactions than barbituric acid/vanillin and barbituric acid/3-hydroxybenzaldehyde derivatives.

Abstract
The roots of F. haussknechtii are used by local people in order to treat wounds and urinary infections. Ferula species are rich in bioactive compounds with biological effects. In line with our previous studies about screening antibacterial natural products, five terpenoid derivatives were purified from Ferula haussknechtii. The separation and purification were performed by column chromatography. Their structures were determined by 1 D and 2 D NMR as hawraman 8-p-hydroxybenzoyl-tovarol (1), ferutinin (2), lancerotriol 6-(p-hydroxybenzoate) (3), chimganin (4), and chimgin (5). Then, the antibacterial effects of the purified compounds were evaluated by measuring their MIC values against Gram-positive and Gram-negative bacteria. The results showed that compound (1) had the most antibacterial effect on Bacillus cereus (MIC = 16 µg/mL). The antibacterial effects of F. haussknechtii compounds are in line with their local application and it is suggested that further studies should be conducted to determine their mechanism of action.

Abstract
Life expectancy is growing especially in developed countries. In this regard, aging-associated diseases such as Alzheimer's disease (AD) are more common. Multi interconnected pathological factors involved in AD demand multi-target therapeutics. AChE, as a well-known target in AD, decreases the acetylcholine (ACh) in cholinergic synapse and, besides, increases the rate of amyloid-beta (Aβ) aggregation. To block the destructive effects of AChE on cholinergic neurons in AD, we designed a peptidic inhibitor of the peripheral anionic site (PAS). The PAS plays a crucial role to attract and direct the ACh to the enzyme active site and increase the rate of Aβ aggregation by changing the folding state. We utilized the template-based approach in combination with molecular docking, molecular dynamic simulation, and data mining to design a peptide library. Scoring was performed according to binding energy and the interaction profile of AChE inhibitors. The best candidate (p8, RMLRTTRY) was synthesized using solid-phase peptide synthesis, purified by RP-HPLC, and identified by ESI-MS. The inhibitory effect of p8 on AChE was 102.2 ± 15.2 μM. The kinetic and molecular modeling studies indicated the mixed inhibition mechanism for p8. The Arg residues in p8 had an essential role in binding to PAS.

Abstract
PURPOSE The therapeutic use of herbal medicines for the diseases, including cancer, is increasing due to their lower side effects. The present research evaluated the effect of Peucedanum chenur chloroformic extract (PCCE) on cell proliferation against HCT-116 human colorectal cancer cell line. METHODS The cytotoxic effect of PCCE was evaluated by MTT assay. The activity of the Wnt/B-catenin pathway was assayed through measuring the expression of miR-135b, miR-21, and APC genes by real-time PCR. The flow cytometry and scratch tests were used to study the cell cycle and cell migration, respectively. Also, the antioxidant activity of PCCE was measured by DPPH and iron-chelating tests. RESULTS The results showed the downregulation of miR-135b and miR-21 and overexpression of the APC gene. Furthermore, PCCE decreased the free radicals, cell migration, and cell proliferation. The antioxidant activity of PCCE was confirmed by standard tests. CONCLUSION Altogether, our findings suggest that purified compounds of PCCE could be developed as a potent chemo-preventive drug for the treatment of CRC.

Abstract
Context: Satureja khuzistanica Jamzad. (Lamiaceae), is known for its antifungal and antioxidant compounds, especially rosmarinic acid (RA).Objective: The study examines the effect of elicitors on RA production and phytochemical properties of S. khuzistanica.Materials and methods: In vitro plants were treated with methyl jasmonate (MeJA) and multi-walled carbon nanotubes (MWCNTs). In vivo plants were treated with MWCNTs and salicylic acid (SA). RA was measured by HPLC. Catalase (CAT), guaiacol peroxidase (POD) and ascorbate peroxidase (APX) were quantified. DPPH and β-carotene were assayed in in vivo extracts. The antifungal effects of extracts were evaluated against Fusarium solani K (FsK).Results: The highest RA contents of in vitro plants were 50 mg/L MeJA (140.99 mg/g DW) and 250 mg/L MWCNTs (140.49 mg/g DW). The highest in vivo were 24 h MWCNTs (7.13 mg/g DW) and 72 h SA (9.12 mg/g DW). The maximum POD and APX activities were at 100 mg/L MeJA (5 and 4 mg protein, respectively). CAT had the highest activities at 50 mg/L MeJA (2 mg protein). DPPH and β-carotene showed 50% and 80% inhibition, respectively. The FsK aggregation was the lowest for in vitro extract in number of conidia [1.82 × 1010], fresh weight (6.51 g) and dry weight (0.21 g) that proved RA inhibitory effects. The callus reduces FsK growth diameter to 2.75 on the 5th day.Discussion and conclusions: Application of MeJA, SA, and MWCNTSs could increase RA in S. khuzistanica and highlighted potential characteristics in pharmaceutical and antifungal effects.

Abstract
Introduction: Diabetes mellitus (DM) is one of the most frequent metabolic diseases that affect various body systems. Cognitive impairment caused by diabetes is gaining more acceptance and attention. In this study, we have investigated the effects of a traditionally herbal formulation (THF) on oxidative stress (OS) and cognitive deficits in type 2 diabetic rats. Methods: Thirty-six male Wistar rats were divided into six groups: control group, diabetic group, diabetic+100, 200 or 300mg/kg THF, diabetic+glibenclamide (G) 5mg/kg. Streptozotocin-nicotinamide was used to induce type-II diabetes mellitus. Spatial and passive avoidance learning and memory function were evaluated by Morris Water Maze (MWM), novel object recognition test (NORT) and open field test (OFT). The OS biomarkers were also analyzed. The THF was standardized using RP-HPLC according to phenolic and flavonoids compounds. Results: Indicated that in the diabetic treated (300mg/kg THF and G) vs. diabetic groups, body weight and insulin were significantly increased and the levels of fasting blood glucose significantly reduced. OS was improved in the treated (300mg/kg THF) groups. Furthermore, we noticed that diabetic treated groups (300mg/kg THF) vs. diabetes caused in significant decreases of the travelled distance and escape latency to find the hidden platform, also increased in the time spent and travelled distance in the target quadrant in MWM test, exploration time in NORT and total distance moved in OFT. Conclusion: These findings suggest that THF ameliorated learning and memory deficits in type 2 diabetic rats via reducing OS. THF can be used with a caution against human DM.

Abstract
Background: Studies have shown that organophosphorus pesticides such as malathion induces oxidative stress injury and tissue damage.
Objectives: This research aimed to determine the effects of the hydroalcoholic extracts of Satureja Avromanica (SA) on the liver function of malathion-poisoned animals.
Methods: Twenty-eight rats were divided into four groups of the control, SA (20 mg/kg), malathion+SA, and malathion. Animals received malathion 150 mg/kg and SA 20 mg/kg for one week through intraperitoneal injection. Then, their liver and blood samples were extracted, and alanine aminotransferase, aspartate aminotransferase concentrations in serum as well as biomarkers of oxidative stress such as Lipid Peroxidation (LPO), Total Antioxidant Capacity (TAC) and Total Thiol Groups (TTG) in the liver tissue were measured.
Results: The results showed that the SA administration reduced the level of liver LPO compared with that in the malathion group. Also, receiving SA increased liver TAC and TTG levels in rats, which this difference was significant compared with the malathion group. Besides, the SA group showed a significant decrease in liver enzyme levels, compared with the malathion-treated group.
Conclusion: According to the results, SA exerted protective effects against malathion poisoning, through reduction of oxidative stress. Therefore, SA may be an antioxidant to counteract the harmful effects of malathion poising in liver tissue.

Biochemical and Histological Evidence on the Protective Effects of Allium hirtifolium Boiss (Persian Shallot) as an Herbal Supplement in Cadmium-Induced Hepatotoxicity. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2020; 2020:7457504. [PMID: 32655668 PMCID: PMC7317314 DOI: 10.1155/2020/7457504] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Revised: 05/22/2020] [Accepted: 05/29/2020] [Indexed: 01/03/2023]
Abstract
MATERIALS AND METHODS Thirty-six male Wistar rats were divided into six groups: groups 1, 2, and 3 received vehicle, Cd (100 mg/L/day by drinking water), and A. hirtifolium extract (200 mg/kg/day; orally), respectively. Groups 4, 5, and 6 were Cd groups which were treated with A. hirtifolium extract (50, 100, and 200 mg/kg/day, respectively). After 2 weeks, liver enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) and also oxidative stress biomarkers including lipid peroxidation (LPO), total antioxidant capacity (TAC), total thiol molecule (TTM), and the histopathological changes were determined using standard procedure. RESULTS The findings showed that Cd caused a remarkable rise in levels of serum hepatic enzymes such as ALT (P < 0.001), AST (P < 0.01) and ALP (P < 0.001) compared with the control group. In addition, Cd led to the decreasing of the levels of TTM (P < 0.001) and TAC (P < 0.001) and increasing of LPO (P < 0.001) in liver tissue in comparison with the control group. In this regard, remarkable vascular congestion, hepatocellular degeneration, and vacuolization were observed in hepatic tissue of Cd-treated rats. Following the administration of A. hirtifolium extract, a significant improvement was observed in the functional and oxidative stress indices of hepatic tissue alongside histopathologic changes. CONCLUSION The current study indicated that the A. hirtifolium extract might prevent hepatic oxidative injury by improving oxidant/antioxidant balance in rats exposed to Cd.

Abstract
Capparis spinosa is an edible medicinal plant which is considered as an excellent source of rutin. Rutin is a glycoside of the flavonoid quercetin that has been reported to have a beneficial role in controlling various diseases such as hypertension, arteriosclerosis, diabetes, and obesity. In this study, the partial cDNA of four genes involved in the rutin biosynthetic pathway including 4-coumaroyl CoA ligase (4CL), flavonoid 3′-hydroxylase (F3′H), flavonol synthase (FLS) and flavonol-3-O-glucoside L-rhamnosyltransferase (RT) were identified in C.spinosa plants for the first time. The protein sequences of these genes shared high similarity with the same proteins in other plant species. Subsequently, the expression patterns of these genes as well as rutin accumulation in C.spinosa leaves treated with different concentrations of salicylic acid (SA) and methyl jasmonate (MeJA) and also in different tissues of Caper plants treated with 100 mgL−1 SA and 150 μM MeJA were evaluated. The expression of all four genes was clearly up-regulated and rutin contents increased in response to MeJA and SA treatments after 24 h. The highest rutin contents (5.30 mgg−1 DW and 13.27 mgg−1 DW), as well as the highest expression levels of all four genes, were obtained using 100 mgL−1 SA and 150 μM MeJA, respectively. Among the different tissues, the highest rutin content was observed in young leaves treated with 150 μM MeJA, which corresponded to the expression of related genes, especially RT, as a key gene in the rutin biosynthetic pathway. These results suggest that rutin content in various tissues of C. spinosa can be enhanced to a significant extent by MeJA and SA treatments and the gene expression patterns of rutin-biosynthesis-related genes are regulated by these elicitors.

Abstract
Alzheimer's disease is a progressive neurodegenerative disorder and patients suffer from memory loss, a decline in language skill and impairment in other cognitive functions. In the cholinergic hypothesis, dysfunction of cholinergic neurons especially in the hippocampus and cerebral cortex contributes to cognitive decline in patients. So agents that enhance acetylcholine concentration could improve cognitive function. AChEIs are among the most studied anti-Alzheimer agents. Galbanic acid as a natural compound with a sesquiterpene coumarin scaffold is a weak inhibitor of AChE. In the present contribution, we discussed the impact of carboxylic group ionization on inhibitory effects. We performed in vitro and in silico studies on galbanic acid, methyl and ethyl galbanates as AChE inhibitors. The order of inhibitory effect on AChE was obtained as ethyl galbanate ∼ methyl galbanate > galbanic acid. Our study highlights the important role of the physicochemical properties of natural lead compounds in each specific assay.Communicated by Ramaswamy H. Sarma.

Abstract
Introduction: Treatment of Helicobacter pylori has various side effects like antibiotic resistance. The purpose of this study was to evaluate the effects of cinnamon extract on complications of treatment and eradication of H. pylori in infected people. Methods: In this randomized clinical trial, a total of 98 eligible healthy and H. pylori-infected patients approved by esophageal endoscopy were selected. The cinnamon group received multi-drug treatment including clarithromycin, amoxicillin and pantoprazole as well as a cinnamon extract capsule. The control group received multi-drug treatment and a 40 mg starch capsule. In order to analyze the cinnamon extract efficacy, the urea breath test (UBT) was performed 3 months after the start of treatment. Clinical symptoms were evaluated by a questionnaire at the beginning (day of 0), 7 days and 14 days after starting treatment. Results: The clinical symptoms such as nausea, vomiting, diarrhea, constipation, blurred vision, headache, metallic flavor, epigastric pain, burp, and appetite were significantly reduced in the cinnamon group (P < 0.05). The odds ratio exhibited a higher eradication rate of H. pylori in the cinnamon group (73.47% in the cinnamon group compared to 53.06% in the control group) (P = 0.036). Conclusion: Cinnamon as assisted therapy is able to alleviate the disease and reduce the complications of H. pylori treatment.

[PMID: 31970021 PMCID: PMC6970575 DOI: 10.3831/kpi.2019.22.032] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 07/18/2019] [Accepted: 11/25/2019] [Indexed: 12/26/2022] Open
Abstract
Objectives Allium jesdianum (Aj) is a medicinal plant that has highlighted pharmacological features. In this study, the effects of Aj extract were examined on acetaminophen (APAP)-induced hepatic failure in rats. Methods Methanolic fraction of hydro-alcoholic extract of Aj was obtained by silica gel column chromatography method. Animals were randomly divided into four groups each containing six rats and treated by gavage as follows: the first and second groups received normal saline, the third and fourth groups were received with 50 and 100 mg/kg of Aj extract, respectively. After two consecutive weeks, the groups 2–4 were given a single dose of APAP (2 g/kg). After 48 hours, blood and liver samples were collected for biochemical and histological examinations. Results The findings of the study demonstrated that APAP caused a significant increase in ALT (P < 0.001), AST (P < 0.001), LDH (P < 0.001), ALP (P < 0.001) serum levels, hepatic lipid peroxidation (LPO; P < 0.001) and nitric oxide (NO; P < 0.001). In this regard, APAP led to the depletion of the total antioxidant capacity (TAC; P < 0.001), glutathione and total thiol groups (TTGs; P < 0.001), and structural change in the liver. In the Aj extract groups, a considerable improvement was found in the hepatic function alongside the histopathologic changes. Conclusion This investigation indicated that the influential effects of Aj extract in APAP-induced hepatic failure might depend on its effect on improving oxidant/antioxidant balance in hepatic tissue.

Abstract
Allium tripedale (A. tripedale) is a species of wild Allium native to northwest Iran that its hepatoprotective effects have not yet been confirmed. This study investigated the effect of A. tripedale plant against acetaminophen (APAP)-induced acute liver damage. After preliminary studies, the A. tripedale methanol fraction (ATMF) was selected for in vivo study. Thirty-six rats were divided into six groups of 6 each and treated by gavage as follows: groups 1 and 2 received normal saline; group 3 received 400 mg/kg of ATMF; and groups 4-6 were treated with 100, 200, and 400 mg/kg of ATMF, respectively. After two consecutive weeks, except groups 1 and 3, rats were administered with an oral single dose of APAP (2 g/kg). After 48 h, blood and liver samples were collected for histological and biochemical examinations. The results showed that APAP caused a significant increase in alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase and alkaline phosphatase serum levels, lipid peroxidation (all with P < 0.001) and hepatic nitric oxide (P < 0.01). In addition, APAP led to the depletion of the total antioxidant capacity, total thiol group (both with P < 0.001), and structural alterations in the hepatic tissue. Following administration of ATMF extract, a significant improvement was observed in the functional and oxidative stress markers of hepatic tissue alongside histopathologic changes. In conclusion, the present study showed that the administration of ATMF might prevent hepatic oxidative damage by improving oxidant/antioxidant balance in animals exposed to APAP.

Abstract
Introduction Pesticides are used as essential tools to control vector-borne diseases and agricultural pests and maintain quality and quantity crop production. Scientists attempt to use derived plant natural products due to environmental safety and low mammalian toxicity. Therefore, the cytotoxicity of malathion and Nepeta crispa essential oil against vertebrate L929 and invertebrate Sf9 cell lines were investigated. Methods About 2×103 cells were placed into the wells of a 96-well plate experiments. Then appropriate concentrations of malathion and N. crispa essential oil added to the wells. The cells were allowed to grow for 3-5 days and estimated the cell numbers. Control cell wells contained only cells with DMSO. All treatments and controls repeated at least four replicates. Results About 2×103 cells were placed into the wells of a 96-well plate experiments. Then appropriate concentrations of malathion and N. crispa essential oil added to the wells. The cells were allowed to grow for 3-5 days and estimated the cell numbers. Control cell wells contained only cells with DMSO. All treatments and controls repeated at least four replicates. Conclusion Plant essential oil not only had no negative effects but also had boosting effects on the L929 cell viability. Nepeta crispa essential oil had negative effects on the Sf9 cell viability with the differences that derived plant natural products containing environmentally friendly and readily biodegradable derivatives, hydrolyzing rapidly in nature and nearly having no destructive effects on mammals and environment.

Abstract
The effects of medium, gibberellic acid (GA3) and stratification treatments on the seed germination of Ferula pseudalliacea were evaluated. Filter paper medium, 500 micro molar GA3 and 8 week chilling treatment were resulted in significantly more seed germination than others. F. pseudalliacea was also transformed by Agrobacterium rhizogenes. Explants from young leaves, stems, cotyledon, and embryo were inoculated with A. rhizogenes strains ATCC 15834, 1724, A4, LB9402 and Ar318. Hairy roots were induced only from 10 to 12-days embryo explants using strains ATCC 15824 and 1724. Although, the transformation efficiency of ATCC 15834 (4%) strain was higher than 1724 (2%). Maximum hairy root transformation frequency (25%) was obtained in infection time of 10 min compared to that of 20 (20%) and 30 (5%) min. In addition, the transformation rate was significantly higher at the inoculation time of 72 h (29%) compared to that of 48 h (22%) and 24 h (6%). Transgenic hairy root lines were confirmed by PCR amplification of rolB gene. Hairy root lines were produced higher biomass in half B5 medium compared to that of half MS medium. Hairy roots lines from the strain ATCC 15834 produced more hairy root numbers and fresh and dried biomass compared to that of the strain 1724. Analyses of transgenic hairy root and natural roots extracts using HPLC showed that all the hairy root lines produced farnesiferol B.

Abstract
Yarrow (Achillea millefolium) is a medicinal plant from the Asteracea which biosynthesize different secondary metabolites especially terpenes and phenylpropanoids. To improve our understanding of the regulatory mechanisms behind the biosynthesis of these compounds we analyzed the expression of some genes associated with the biosynthesis of terpenes and phenylpropanoids in different tissues and in response to trans-cinnamic acid (tCA) as an inhibitor of PAL activity. Isolation and expression analysis of DXR, GPPS, PAL and CHS genes together with linalool synthase (LIS) as monoterpene synthase was conducted in different developmental stages of leaves, flowers and in response to trans-cinnamic acid (tCA). Differential expression of these genes observed in different tissues. tCA up-regulated the biosynthetic genes of monterpenes and down-regulated the biosynthetic genes of phenylpropanoids. Gene expression analysis in intact leaves and leaves without glandular trichomes showed that DXR, LIS, PAL and CHS are highly expressed in glandular trichomes while GPPS expressed ubiquitously. Analysis of essential oils composition showed that sesquiterpenes and monoterpenes are main compounds; in which from 57 identified compounds the highest were germacreneD (% 11.5), guaiol (%10.38), spatulenol (%8.73) and caryophyllene oxide (%7.48).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chronic periodontitis is an inflammatory process of the oral cavity that is caused by different reasons. Streptococcus mutans bacteria is the main cause of the disease. Scrophularia striata in Iranian traditional medicine is used to heal inflammation of gum and mouth. Also, In vitro anti-bacterial effect of S. striata in S. mutans have been demonstrated. AIM OF THE STUDY Clinical, in vitro and chemical constituent studies of S. striata on chronic periodontitis disease. MATERIALS AND METHODS This study is a randomized clinical trial that was performed in Dental College, Hamadan University of Medical Sciences. Fifty patients with chronic periodontitis (20-50 years old) were selected and the study was approved and registered in Iranian Registry of Clinical Trials as number IRCT2015081323468N1 prior to the experiment. The 50 patients were divided into two groups. One group used herbal mouthwash that was made from hydro alcoholic extract of S. striata and another group used Irsha mouthwash (Iranian form of Listerine mouthwash). Patients were followed up after two weeks and four weeks of using mouthwash for assessment of plaque index (PI), pocket depth (PD), bleeding on probing (BOP) and counting Streptococcus mutans. The mouthwash was standardized according to gallic acid, quercetin and apigenin reference using the RP-HPLC method. The total phenolic and flavonoids contents were also determined spectrophotometerically. RESULTS S. striata in the short term, improve plaque index, pocket depth and bleeding on probing but the number of Streptococcus mutans changed significantly in the long term and is more potent in comparison to Irsha mouthwash. The mouthwash was standardized according to gallic acid, quercetin and apigenin standard (3, 24, 11 μg, respectively). The total phenolic and flavonoid content of mouthwash were 120.7 μg GAE/100 cc and 78.6 μg QE/100 cc respectively. CONCLUSIONS S. striata mouthwash is effective in the treatment of chronic periodontitis disease and is more potent comparing the Iranian Irsha mouthwash.

Abstract
Ferula species have diverse biological functions. This study set out to investigate the anti-proliferative effects of methanolic extract of F. pseudalliacea against human colon cancer HCT-116 cell line. Cytotoxic effects of F. pseudalliacea on HCT-116 cells was estimated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. Real-time polymerase chain reaction (PCR) and Western blot were employed to analyze BAX and Bcl2 expression. Cell cycle analysis and apoptosis were conducted using flowcytometry and Annexin V/ propidium iodide (PI) staining. Rhodamine 123 staining and enzyme-linked immunosorbent assay (ELISA) assay were employed to quantify the mitochondria membrane potential (MMP) and caspase 3 activity, respectively. F. pseudalliacea markedly decreased HCT-116 cells viability. The gene and protein expression of BAX were increased, whereas Bcl-2 was decreased in F. pseudalliacea treated cells. F. pseudalliacea induced apoptosis via promotion of cell cycle arrest, caspase 3 activation, and destruction of MMP. These results demonstrate that F. pseudalliacea extract is able to induce apoptosis in HCT-116 cells mainly by activation of the mitochondrial pathway.

Abstract
Cadmium (Cd), as a toxic metal, can accumulate in kidneys and induce renal failure. This study was undertaken to evaluate the protective effects of Allium hirtifolium Boiss bulbs against Cd-induced renal failure in rats. Thirty-six rats were divided into 6 groups: group 1, 2, and 3 received vehicle, Cd (100 mg/L/day by drinking water), and AhB extract (200 mg/kg/day; orally), respectively. Groups 4, 5, and 6 were Cd groups which treated AhB extract (50, 100, and 200 mg/kg/day, respectively). After 2 weeks, renal function and oxidative stress markers were determined by using colorimetric methods. Our findings showed that Cd caused a significant increase in creatinine (Cr; p<0.05), uric acid (p<0.01), BUN (p<0.05), serum levels, lipid peroxidation (LPO; p<0.01), and nitric oxide (NO; p<0.01); the depletion of the total antioxidant capacity (TAC; p<0.01) and total thiol molecules (TTM; p<0.001); and structural alterations in the renal tissue. Following AhB extract administration, a remarkable improvement was observed in the functional and oxidative stress markers of renal tissue.This study suggests that AhB may prevent progression of Cd-induced renal failure via improvement of oxidative/antioxidant balance in renal tissue.
