Abstract
Herein, we isolated five natural alkaloids, iso-corydine (iso-CORY), corydine (CORY), sanguinarine (SAN), chelerythrine (CHE) and magnoflorine (MAG), from traditional medicinal herb Dicranostigma leptopodum (Maxim.) Fedde (whole herb) and elucidated their structures. Then we synthesised G5. NHAc-PBA as targeting dendrimer platform to encapsulate the alkaloids into G5. NHAc-PBA-alkaloid complexes, which demonstrated alkaloid-dependent positive zeta potential and hydrodynamic particle size. G5. NHAc-PBA-alkaloid complexes demonstrated obvious breast cancer MCF-7 cell targeting effect. Among the G5. NHAc-PBA-alkaloid complexes, G5.NHAc-PBA-CHE (IC50=13.66 μM) demonstrated the highest MCF-7 cell inhibition capability and G5.NHAc-PBA-MAG (IC50=24.63 μM) had equivalent inhibitory effects on cell proliferation that comparable to the level of free MAG (IC50=23.74 μM), which made them the potential breast cancer targeting formulation for chemotherapeutic application. This work successfully demonstrated a pharmaceutical research model of 'natural bioactive product isolation-drug formulation preparation-breast cancer cell targeting inhibition'.

Abstract
This article reviews the geographical distribution, ethnomedicinal applications, and phytochemistry of the genus Monanthotaxis Baill, tribe Uvariae of the family Annonaceae. The reviewed works of literature were collected from various electronic databases including Google Scholar, PubMed, Science Direct, The International Plant Names Index (IPNI), and Research Gate. During this review, ninety-eight species of the genus Monanthotaxis were found to be widely distributed in tropical Africa. Some of those species are used in folkloric medicine by various communities to manage diseases and disease conditions such as fever, vomiting, headache, stomach-ache, malaria, helminthiasis, and hysteria. In the past 44 years (1979 to 2023), one hundred and nineteen secondary metabolites with different biomedical potentials have been reported from this genus. The reported compounds are categorised into flavonoids, alkaloids, terpenoids, polyoxygenated cyclohexane, and cyclohexene derivatives, benzyl derivatives, cinnamic acid derivatives, and stilbenoids. Most of the reported compounds showed an array of bioactivities corroborating the use of some members of the genus in folkloric medicine.

Abstract
Nuciferine aporphine alkaloid mainly exists in Nelumbo nucifera Gaertn and is a beneficial to human health, such as anti-obesity, lowering blood lipid, prevention of diabetes and cancer, closely associated with inflammation. Importantly, nuciferine may contribute to its bioactivities by exerting intense anti-inflammatory activities in multiple models. However, no review has summarized the anti-inflammatory effect of nuciferine. This review critically summarized the information regarding the structure-activity relationships of dietary nuciferine. Moreover, biological activities and clinical application on inflammation-related diseases, such as obesity, diabetes, liver, cardiovascular diseases, and cancer, as well as their potential mechanisms, involving oxidative stress, metabolic signaling, and gut microbiota has been reviewed. The current work provides a better understanding of the anti-inflammation properties of nuciferine against multiple diseases, thereby improving the utilization and application of nuciferine-containing plants across functional food and medicine.

Abstract
Alkaloids are a diverse group of natural phytochemicals. These phytochemicals in plants provide them protection against pests, and herbivorous organisms and also control their development. Numerous of these alkaloids have a variety of biological effects, and some have even been developed into medications with different medicinal properties. This review aims to provide a broad overview of the numerous naturally occurring alkaloids (isolated from both terrestrial and aquatic species) along with synthetically produced alkaloid compounds having prominent antiviral properties. Previous reviews on this subject have focused on the biological actions of both natural and synthetic alkaloids, but they have not gone into comprehensive detail about their antiviral properties. We reviewed here several antiviral alkaloids that have been described in the literature in different investigational environments i.e. (in-vivo, in-ovo, in-vitro, and in-silico), and found that these alkaloid compounds have significant antiviral properties against several infectious viruses. These alkaloids repressed and targeted various important stages of viral infection at non-toxic doses while some of the alkaloids reported here also exhibited comparable inhibitory activities to commercially used drugs. Overall, these anti-viral effects of alkaloids point to a high degree of specificity, implying that they could serve as effective and safe antiviral medicines if further pursued in medicinal and pharmacological investigations.

Abstract
Viruses are widely recognized as the primary cause of infectious diseases around the world. The ongoing global pandemic due to the emergence of SARS-CoV-2 further added fuel to the fire. The development of therapeutics becomes very difficult as viruses can mutate their genome to become more complex and resistant. Medicinal plants and phytocompounds could be alternative options. Isoquinoline and their related alkaloids are naturally occurring compounds that interfere with multiple pathways including nuclear factor-κB, mitogen-activated protein kinase/extracellular-signal-regulated kinase, and inhibition of Ca2+-mediated fusion. These pathways play a crucial role in viral replication. Thus, the major goal of this study is to comprehend the function of various isoquinoline and related alkaloids in viral infections by examining their potential mechanisms of action, structure-activity relationships (SAR), in silico (particularly for SARS-CoV-2), in vitro and in vivo studies. The current advancements in isoquinoline and related alkaloids as discussed in the present review could facilitate an in-depth understanding of their role in the drug discovery process.

Abstract
Background Viral infections have a history of abrupt and severe eruptions through the years in the form of pandemics. And yet, definitive therapies or preventive measures are not present. Herbal medicines have been a source of various antiviral compounds such as Oseltamivir, extracted using shikimic acid from star anise (Illicium verum) and Acyclovir from Carissa edulis are FDA (Food and Drug Administration) approved antiviral drugs. In this study, we dissect the anti-coronavirus infection activity of Cissampelos pareira L (Cipa) extract using an integrative approach. Methods We analysed the signature similarities between predicted antiviral agents and Cipa using the connectivity map (https://clue.io/). Next, we tested the anti-SARS-COV-2 activity of Cipa in vitro. Molecular docking analyses of constituents of with key targets of SARS-CoV2 protein viz. spike protein, RNA‑dependent RNA‑polymerase (RdRp) and 3C‑like proteinase. was also performed. A three-way comparative analysis of Cipa transcriptome, COVID-19 BALF transcriptome and CMAP signatures of small compounds was also performed. Results Several predicted antivirals showed a high positive connectivity score with Cipa such as apcidin, emetine, homoharringtonine etc. We also observed 98% inhibition of SARS-COV-2 replication in infected Vero cell cultures with the whole extract. Some of its prominent pure constituents e.g. pareirarine, cissamine, magnoflorine exhibited 40–80% inhibition. Comparison of genes between BALF and Cipa showed an enrichment of biological processes like transcription regulation and response to lipids, to be downregulated in Cipa while being upregulated in COVID-19. CMAP also showed that Triciribine, torin-1 and VU-0365114–2 had positive connectivity with BALF 1 and 2, and negative connectivity with Cipa. Amongst all the tested compounds, Magnoflorine and Salutaridine exhibited the most potent and consistent strong in silico binding profiles with SARS-CoV2 therapeutic targets.

Abstract
Breast cancer is the leading cause of cancer mortality in women. In this study, liriodenine and lysicamine from Goniothalamus elegans Ast. were investigated for their anti-breast cancer activity based on their molecular interactions with three proteins related to breast cancer. Liriodenine had predicted binding affinities for BRCA1, BRCA2, and estrogen receptor alpha of −6.2, −7.9, and −8.3 kcal/mol, respectively. Lysicamine had predicted binding affinities of −5.8, −7.2, and 7.6 kcal/mol. To evaluate the biological activity of liriodenine and lysicamine, we studied their in vitro cytotoxic effects on MCF-7 cells. These alkaloids showed significant inhibitory effects with IC50 values of 33.31 and 70.03 µM. These results suggest that Goniothalamus elegans could be a promising medical plant for breast cancer treatment. Further studies are needed to understand the molecular mechanisms and improve the toxicity of liriodenine and lysicamine for clinical use.

Abstract
In the current scenario, the increasing prevalence of diverse microbial infections as well as emergence and re-emergence of viral epidemics with high morbidity and mortality rates are major public health threat. Despite the persistent production of antiviral drugs and vaccines in the global market, viruses still remain as one of the leading causes of deadly human diseases. Effective control of viral diseases, particularly Zika virus disease, Nipah virus disease, Severe acute respiratory syndrome, Coronavirus disease, Herpes simplex virus infection, Acquired immunodeficiency syndrome, and Ebola virus disease remain promising goal amidst the mutating viral strains. Current trends in the development of antiviral drugs focus solely on testing novel drugs or repurposing drugs against potential targets of the viruses. Compared to synthetic drugs, medicines from natural resources offer less side-effect to humans and are often cost-effective in the productivity approaches. This review intends not only to emphasize on the major viral disease outbreaks in the past few decades and but also explores the potentialities of natural substances as antiviral traits to combat viral pathogens. Here, we spotlighted a comprehensive overview of antiviral components present in varied natural sources, including plants, fungi, and microorganisms in order to identify potent antiviral agents for developing alternative therapy in future.

Abstract
In order to explore a new method to detect the freshness of lotus seeds, the lotus seeds stored for 0, 1, 2, and 3 years, respectively, were used as experimental materials and analyzed by DAPCI-MS (desorption atmospheric pressure chemical ionization-mass spectrometry). The obtained data were processed by principal component analysis (PCA) and backpropagation artificial neural networks (BP-ANNs). The result showed that DAPCI-MS could obtain abundant chemical material information from the slice surface of lotus seeds. The BP-ANNs model could be applied not only to distinguish fresh and aged lotus seeds with the testing set accuracies of 95.0% and 91.7%, respectively, but also to classify lotus seeds with different storage times with the testing set accuracies of 90.0%, 85.0%, 85.0%, and 90.0%, respectively. The paper developed a fast, convenient, and accurate method for the freshness detection of lotus seed and would provide reliable reference value for rapid authentication of food freshness by the rapid mass spectrometry technique.

Abstract
To explore the potential of aporphine alkaloids, a novel series of functionalized aporphine analogues with alkoxy (OCH3 , OC2 H5 , OC3 H7 ) functional groups at C1/C2 of ring A and an acyl (COCH3 and COPh) or phenylsulfonyl (SO2 Ph and SO2 C6 H4 -3-CH3 ) functionality at the N6 position of ring B of the aporphine scaffold were synthesized and evaluated for their arachidonic acid (AA)-induced antiplatelet aggregation inhibitory activity and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical-scavenging antioxidant activity, with acetylsalicylic acid and ascorbic acid as standard references, respectively. The preliminary structure-activity relationship related to AA-induced platelet aggregation inhibitory activity results showed that the aporphine analogues 1-[1,2,9,10-tetramethoxy-6a,7-dihydro-4H-dibenzo[de,g]quinolin-6(5H)-yl]ethanone and 1-[2-(benzyloxy)-1,9,10-trimethoxy-6a,7-dihydro-4H-dibenzo[de,g]quinolin-6(5H)-yl]ethanone to be the best compounds of the series. Moreover, the DPPH free-radical-scavenging antioxidant activity results demonstrated that the aporphine analogues 1,2,9,10-tetramethoxy-6-(methylsulfonyl)-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinoline, 2-ethoxy-1,9,10-trimethoxy-6-(methylsulfonyl)-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinoline, 1-ethoxy-2,9,10-trimethoxy-6-(methylsulfonyl)-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinoline, 2,9,10-trimethoxy-6-(methylsulfonyl)-1-propoxy-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinoline, and 1-(benzyloxy)-2,9,10-trimethoxy-6-(methylsulfonyl)-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinoline were the best compounds of the series. Moreover, in silico molecular docking simulation studies of the active analogues were also performed.

Abstract
Traditional Chinese herbal drugs have been used for thousands of years in Chinese pharmacopoeia. The bark of Magnolia officinalis Rehder & E. Wilson, known under the pinyin name "Houpo", has been traditionally used in Chinese and Japanese medicines for the treatment of anxiety, asthma, depression, gastrointestinal disorders, headache, and more. Moreover, Magnolia bark extract is a major constituent of currently marketed dietary supplements and cosmetic products. Much pharmacological activity has been reported for this herb and its major compounds, notably antioxidant, anti-inflammatory, antibiotic and antispasmodic effects. However, the mechanisms underlying this have not been elucidated and only a very few clinical trials have been published. In vitro and in vivo toxicity studies have also been published and indicate some intriguing features. The present review aims to summarize the literature on M. officinalis bark composition, utilisation, pharmacology, and safety.

Abstract
Background Acquired Immune Deficiency Syndrome (AIDS) is the advanced stage of infection caused by Human Immunodeficiency Virus (HIV). HIV/AIDS had a great impact on society, both as an illness and as a source of discrimination. Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) are structurally diverse group of compounds which binds to Reverse Transcriptase (RT) enzyme of HIV. Like other anti-HIV drugs, long-term clinical effectiveness of approved NNRTIs has been hampered due to the rapid development of drug resistance. So, there is an urgent need to discover the NNRTIs, which can be effective against the drug sensitive as well as drug resistant strains of HIV-1 RT. Results Two series of novel thirty, 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline analogues (5a-o) and (8a-o) were designed and synthesized as inhibitor of HIV-1 reverse transcriptase. All the synthesized compounds were characterized by infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, mass spectroscopy and evaluated for in-vitro RT inhibitory activity. Among the tested compounds, eighteen compounds exhibited more than 50 % inhibition at tested 100 μM concentration, in which two compounds 8h and 8l showed promising inhibition (74.82 and 72.58 %) respectively. The preliminary structure–activity relationship (SAR) of the test compounds and docking studies of the two significantly active compounds 8h and 8l were performed to examine their putative binding with HIV-RT. Predicted physiochemical parameters of the synthesized compounds were within the acceptable range of drugable properties. Conclusion The results obtained from this investigation revealed that, the synthesized compounds (5a-o) and (8a-o) showed moderate to promising HIV-1 RT inhibition activity. The overall SAR studies can help in identification of further lead as well as in designing of newer potential inhibitor of HIV-1 RT. Best docked pose of compound 8h inside the non-nucleoside inhibitory binding pocket of 3MEE enzyme. ![]()

Abstract
N-Methyllaurotetanine (1) has been reported to display good affinity for the 5-HT1A receptor, but no structure-affinity studies have been performed to date. The commercially available alkaloid boldine (2) was used as the starting material for synthesis of various C-9 alkoxy analogues of N-methyllaurotetanine in order to gauge the effect of C-9 alkylation on affinity and selectivity at 5-HT1A, 5-HT2A, and 5-HT7 receptors. Mitsunobu reactions were implemented in the alkylation steps leading to the analogues. Modest improvement in 5-HT1A affinity was observed upon alkylation for most analogues. Thus, the C-9 hydroxy group of 1 is not critical for affinity to the 5-HT1A receptor. Some analogues displayed high affinity for the 5-HT7 receptor, comparable to N-methyllaurotetanine, with moderate selectivity vs 5-HT1A and 5-HT2A receptors.

Abstract
The continued burden of HIV in resource-limited regions such as parts of sub-Saharan Africa, combined with adverse effects and potential risks of resistance to existing antiretroviral therapies, emphasize the need to identify new HIV inhibitors. Here we performed a virtual screen of molecules from the pan-African Natural Product Library, the largest collection of medicinal plant-derived pure compounds on the African continent. We identified eight molecules with structural similarity to reported interactors of Vpu, an HIV-1 accessory protein with reported ion channel activity. Using in vitro HIV-1 replication assays with a CD4+ T cell line and peripheral blood mononuclear cells, we confirmed antiviral activity and minimal cytotoxicity for two compounds, ixoratannin A-2 and boldine. Notably, ixoratannin A-2 retained inhibitory activity against recombinant HIV-1 strains encoding patient-derived mutations that confer resistance to protease, non-nucleoside reverse transcriptase, or integrase inhibitors. Moreover, ixoratannin A-2 was less effective at inhibiting replication of HIV-1 lacking Vpu, supporting this protein as a possible direct or indirect target. In contrast, boldine was less effective against a protease inhibitor-resistant HIV-1 strain. Both ixoratannin A-2 and boldine also inhibited in vitro replication of hepatitis C virus (HCV). However, BIT-225, a previously-reported Vpu inhibitor, demonstrated antiviral activity but also cytotoxicity in HIV-1 and HCV replication assays. Our work identifies pure compounds derived from African plants with potential novel activities against viruses that disproportionately afflict resource-limited regions of the world.

Abstract
Nuciferine is an important drug candidate for the treatment of obesity-related diseases. However, few investigations have been conducted about the pharmacokinetics and tissue distribution of nuciferine to better understand its behavior and action mechanism in vivo. Thus, a sensitive and reliable liquid chromatography with tandem mass spectrometry (HPLC-MS/MS) method was established and validated for the quantification of nuciferine in rat plasma and tissue samples. The validated method was successfully applied to the pharmacokinetic and tissue distribution study of nuciferine in rats. One-compartmental pharmacokinetic parameters indicated that nuciferine had rapid distribution, extensive tissue uptake, and poor absorption into systemic circulation. The values of absolute bioavailability were (3.8±1.4)%, (4.2±1.3)% and (3.9±1.0)% after oral administration of 2.0, 5.0 and 10.0mg/kg nuciferine and intravenous administration of 0.2mg/kg nuciferine in rats. The results of the tissue distribution study suggested that nuciferine was distributed into the brain, liver and adipose tissue after intravenous administration. In conclusion, the present study may provide a material basis for study of the pharmacological action of nuciferine in the treatment of obesity, and meaningful insights into further study on dosage modification.

Abstract
BACKGROUND Herbal medicines played a major role in the treatment of hepatic disorders, and a number of medicinal plants and their compounds were widely used for the treatment of these disorders, and oxidant stress injury was one of the mechanism of liver injury. MATERIALS AND METHODS Antioxidant activity of Nelumbo nucifera leaves (NU) extracts was assayed by the methods of scavenging 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzo-thiazoline-6-sulfonicacid) (ABTS) radical and ferric reducing antioxidant power (FRAP) in vitro. By intraperitoneal injection carbon tetrachloride (CCl4) to establish acute liver injury model in mice, the levels of Glutamic-pyruvic transaminase (GPT), glutamic-oxaloacetic transaminase (GOT), superoxide dismutase (SOD) and the content of and maleicdialdehyde (MDA) were detected to evaluate hepatoprotective effect of NU using corresponding test kit. RESULTS EtOAC (NUEA) and n-BuOH extracts (NUBU) of N. nucifera leaves had good scavenging DPPH and ABTS radical activity and ferric reducing antioxidant power in vitro. DPPH radical scavenging activity and ferric reducing antioxidant power of NUEA (IC50= 6.68±0.29 µg/mL, RACT50=1749.82±67.03 µmol/g) and NUBU (IC50= 4.61±0.01 µg/mL, RACT50=1995.27±135.71 µmol/g ) were higher than that of BHT (IC50=8.76±0.20 µg/mL, RACT50=1581.68±97.41 µmol/g) and Dangfeiliganning (IC50=28.06±0.17 µg/mL, RACT50=1028.55±3.28 µmol/g). ABTS radical scavenging activity of NUEA (IC50= 5.32±0.12 µg/mL) and NUBU (IC50= 8.16±0.27 µg/mL) were higher than that of Dangfeiliganning (IC50= 9.76±0.16 µg/mL). Thus, hepatoprotective effect of NUEA and NUBU was evaluated on CCl4-induced acute liver injury mice. The results showed that the levels of GOT and GPT in each treatment group significantly decreased (p<0.001 and p<0.01, p<0.05, respectively) except for the group of NUEA (130.8 mg/kg) (p>0.05). The contents of malondialdehyde (MDA) in liver in groups of NUEA (523 mg/kg), NUBU (840.5 and 420.5 mg/kg, repectively) had significant decrease (p<0.001 and p<0.05, respectively), and the level of SOD in liver for each treatment group could significantly decrease (p<0.001, p<0.05, respectively). CONCLUSION NUEA and NUBU had significantly hepatoprotective effect for Calcium tetrachloride CCl4-induced liver injury, which might be attributable to its antioxidant activity.

High-throughput screen of natural product libraries for hsp90 inhibitors. BIOLOGY 2014; 3:101-38.

Abstract
Hsp90 has become the target of intensive investigation, as inhibition of its function has the ability to simultaneously incapacitate proteins that function in pathways that represent the six hallmarks of cancer. While a number of Hsp90 inhibitors have made it into clinical trials, a number of short-comings have been noted, such that the search continues for novel Hsp90 inhibitors with superior pharmacological properties. To identify new potential Hsp90 inhibitors, we have utilized a high-throughput assay based on measuring Hsp90-dependent refolding of thermally denatured luciferase to screen natural compound libraries. Over 4,000 compounds were screen with over 100 hits. Data mining of the literature indicated that 51 compounds had physiological effects that Hsp90 inhibitors also exhibit, and/or the ability to downregulate the expression levels of Hsp90-dependent proteins. Of these 51 compounds, seven were previously characterized as Hsp90 inhibitors. Four compounds, anthothecol, garcinol, piplartine, and rottlerin, were further characterized, and the ability of these compounds to inhibit the refolding of luciferase, and reduce the rate of growth of MCF7 breast cancer cells, correlated with their ability to suppress the Hsp90-dependent maturation of the heme-regulated eIF2α kinase, and deplete cultured cells of Hsp90-dependent client proteins. Thus, this screen has identified an additional 44 compounds with known beneficial pharmacological properties, but with unknown mechanisms of action as possible new inhibitors of the Hsp90 chaperone machine.

Abstract
The identification of tyrosinase inhibitors is important, not only for the treatment of skin hyperpigmentation disorders, such as melasma, but also for the production of cosmetic whitening effects. The aim of this study was the in silico prediction of the naturally occurring lead compounds in three commonly used skin-whitening herbs: Ampelopsis japonica, Lindera aggregata, and Ginkgo biloba. The active ingredients responsible for the whitening effect of these herbs remain largely unknown. The tyrosinase binding affinities and skin permeation, skin irritancy, and corrosive properties of 43 natural constituents of the three herbs were predicted by docking simulations using Surflex-Dock and the QSAR-based Dermal Permeability Coefficient Program (DERMWINTM) and Skin Irritation Corrosion Rules Estimation Tool (SICRET) implemented in Toxtree. Nine constituents of the three herbs were found to have more advanced binding energies than the gold standard whitening agents, arbutin and kojic acid, but 40 were indicative of at least one skin sensitization alert, and many exhibited poor skin permeability. Linderagalactone c and (+)- n-methyllaurotetanine were found to have the strongest prospects for use in topical formulations, as they achieved high predicted tyrosinase binding scores and displayed good skin permeation properties and minimal potential for skin sensitization and irritation.

Abstract
The object of this study was to identify the major active ingredients of the Chinese Traditional Medicine Jiang-Zhi-Ning (JZN) based on the high performance liquid chromatography (HPLC) profiles of plasma samples obtained from beagle dogs at different times after intragastric administration of JZN, crude JZN extracts, different extracted fractions, different subfractions of the active fraction and different isolated ingredients. 2-Hydroxy-1-methoxyaporphin (2H1M), an alkaloid from Nelumbo nucifera, one of the herbs that make up JZN, was identified as the constituent showing the major pharmacodynamic effect. The major metabolites of 2H1M were analyzed and identified as N-demethyl-2-hydroxy-1-methoxyaporphine-2-O-glycuronic acid, 2-hydroxy-1-methoxy-aporphine-2-O-glycuronic acid and 2-hydroxy-1-methoxy-aporphine-2-O-sulphate. This study provided a comprehensive insight into the active components of JZN.

Abstract
A series of synthetic aporphine derivatives structurally related to domesticine and nantenine (ring A, N6 and ring C truncated analogs), was evaluated in MTS cytotoxicity assays against the human colon cancer cell lines, HCT-116 and Caco-2. In general, the C1 position of ring A is tolerant of alkoxy substituents as well as a benzoyl ester functionality. Other modifications evaluated resulted in a decrease in cytotoxic activity. The most potent compounds identified had IC(50) values in the range 23-38 μM, comparable to the known cytotoxic agent, etoposide.

Abstract
Lindera angustifolia Chen is a folk medicine used for the treatment of contusions-induced swelling, rheumatic pains and bellyache in south and the middle part of China. Phytochemical studies showed that aporphine and benzyltetrahydroisoquinoline alkaloids are the characteristic constituents of this plant. In this study, we evaluated the antinociceptive and free radical scavenging properties of six aporphine and two benzyltetrahydroisoquinoline alkaloids isolated from the root of Lindera angustifolia. All alkaloids except magnocurarine exhibited remarkable radical scavenging effects (36-90% scavenging at 25-100microg/ml) in DPPH radical scavenging test, among them norisocorydine showed the hightest activity (SC(50): 14.1microg/ml). Antinociceptive activities were tested by using acetic acid-induced writhing and formalin test at dose of 20mg/kg. Norisocorydine exhibited the highest antinociceptive ability with 83.5% writhing inhibition. Boldine, norboldine showed significant antinociceptive activity with 76.3% and 74.6% writhing inhibition respectively. Indomethacin was used as positive control, which showed 67.8% writhing inhibition at dose of 10mg/kg. Most of the compounds, except N-ethoxycarbonyllaurotetanine and magnocurarine, could significantly inhibit the phase I reaction (P<0.01), and all of them inhibited the phase II reaction (P<0.001) in the formalin tests (indomethacin and morphine were used as positive drugs). The antinociceptive effects exhibited a structure-activity relationship similar to that of the free radical scavenging activities. Above results suggested that the alkaloids from the root of Lindera angustifolia possess both free radical scavenging and antinociceptive activities, and the antinociceptive activity seems to be related to the free radical scavenging effect.

Abstract
A series of nine (+/-)-nantenine derivatives were synthesized and assayed for their pharmacological activities by using tension in aorta and binding experiments in rat brain membrane. Replacing a methyl group with a hydrogen ((+/-)-nornantenine) and an ethyl group at a nitrogen atom ((+/-)-ethylnornantenine) or introducing a hydroxyl group at the alpha/beta position of C-4 or displacement of a methoxy moiety at the C-1 position with a hydroxyl ((+/-)-domesticine) of (+/-)-nantenine decreased the affinity. Moreover, changing a methyl group of (+/-)-domesticine to hydrogen at a nitrogen atom ((+/-)-nordomesticine) caused loss of the activities. These results suggest that a methyl group at a nitrogen atom and a methoxy moiety at C-1 play important roles in the development of the antiserotonergic activity. Molecular modeling analysis of the interaction between the 5-HT2A receptor and (+/-)-nantenine suggested that electron lone pairs of N-6 and of the oxygen atom of the methoxy group at C-1 are important in forming a hydrogen bond to Asp155 and Asn343 of the 5-HT2A receptor, respectively.

Abstract
A series of (+/-)-nantenine derivatives of the natural aporphine alkaloids was synthesized and examined for a blocking action on alpha1-adrenoceptors in rat aorta and A10-cells. The potency of these derivatives was compared with that of an aporphine-related compounds (+)-boldine, an alpha1-adrenoceptor antagonist. Among nine (+/-)-nantenine derivatives having different substituents at N-6, C-1, or C-4 of the aporphine skeleton, (+/-)-domesticine had the most powerful alpha1-adrenoceptor-blocking action. The order of pA2 values was (+/-)-domesticine (8.06+/-0.06)>(+/-)-nordomesticine (7.34+/-0.03)>(+/-)-nantenine (7.03+/-0.03)>(+)-boldine (6.91+/-0.02)>other derivatives. Study of the structure-activity relationships showed that the replacement of a methoxy moiety at C-1 position of (plus minus)-nantenine with a hydroxyl group increased affinity for the receptor. In contrast, replacement of a methyl group with a hydrogen atom or an ethyl group at N-6 position in the (+/-)-nantenine structure decreased affinity for the receptor. These results suggest that a hydroxyl group at the C-1 position and a methyl group at the N-6 position in the (+/-)-nantenine structure are essential for the enhancement of affinity for the alpha1-adrenoceptor.
