ABSTRACT

The genus Actaea plants are widely distributed in China, and the cycloartane triterpenoids are the characteristic constituents of this genus. They are divided into types of cimigenol, hydroshengmanol, shengmanol, cimiacerogenin, acteol, 16, 23-diketo, foetidonol, dahurinol, etc. Cycloartane triterpenoids show many biological activities, such as cytotoxicity, anti-osteoporosis, antiviral, anti-inflammatory, anti-nucleoside transport, neuroprotective, anti-oxidant, antibacterial activities. The present paper reviewed the distribution of the plant resources of Actaea, chemical structures and biological activities of cycloartane triterpenoids, aiming to provide a reference for the further research in the future.

ABSTRACT

Aim To investigate the antitumor effects of cimigenol ( KY17 ) , a novel cycloartane triterpenoid from Cimicifuga , in human colon cancer cells (HCT116).Methods MTT assay was used to deter-mine the effect of KY17 on the proliferation of mouse embryonic fibroblasts ( MEF) and human colon cancer HCT116 cell line.Flow cytometry was employed to de-tect the effect of KY17 on HCT116 cell cycle.Fluores-cence microscopy and flow cytometry were used to ana-lyze the apoptosis .Western blot was used to detect the expression of apoptotic protein (PARP).q-PCR ana-lyzed the expression of miRNA-34a.Results The IC50 of KY17 in MEF and HCT116 cells was 27.28 μmol· L-1 and 9.31μmol· L-1 , respectively.KY17 induced HCT116 cell cycle arrest in G2/M phase and the apoptotic protein PARP cleavage . In addition, KY17 up-regulated the expression of p 53 protein and miRNA-34a.Conclusions KY17 inhibits the prolifera-tion and the cell cycle is arrested in G 2/M, inducing the apoptosis of HCT116 cells. The mechanism is probably related to miRNA-34a up-regulation and p53 activation .

ABSTRACT

The Phytochemical study of Methanol/dichloromethane extract of root of Leplaea mayombenis led to the isolation and identification four limonoids: (8S,9R,10R,11S,13R,17R)-6,11-dihydroxy-14,15-epoxy-4,4,8,10,13-pentamethyl-17-(2-oxo-2,5-dihydrofuran-3-yl-)-11,12,13,15,16,17-hexahydro-4H-cyclopent[α] phenanthrene-3,7(8H,9H,10H,14H)-dione (1), (8S,9R,10R,11S,13R,17R)-6,11-dihydroxy-14,15-epoxy-4,4,8,10,13-pentamethyl -17-(23-methoxy-2-oxo-2,5-dihydrofuran-3-yl-)-11,12,13,15,16,17-hexahydro-4H-cyclopent [α] phenanthrene 3,7(8H,9H,10H,14H)-dione (2), (8S,9R,10R,11S,13R,17R)-6,11-dihydroxy-14,15-epoxy-17- ((s)-2-hydroxy-5-oxo-2,5-dihydrofurano-3-yl)-4,4,8,10,13-pentamethy-l,10,11,12,13,15,16,17-octahydro-4H-cyclopent [α] phenanthrene-3,7(8H,9H,10H,14H)-dione (3), 8S,9R,10R,11S,13R,17R)-1,6,11-trihydroxy-14,15-epoxy-17- [((2s)-2-hydroxy-5-oxo-2,5-dihydrofurano-3-yl)]-4,4,8,10,13-pentamethyl-l,10,11,12,13,15,16,17-octahydro-4H-cyclopent[α]phenanthrene-3,7(8H,9H,10H,14H)-dione (4), one cycloartane : 9,10-cyclopropyl-(3S,5R,8R,13R,14S,17R))-4,4,13,14,17-pentamethyl-l7-((2R,5S,6R)-5,6,7-trihydroxy-6-methylheptan-2-yl)-hexadecahydro-1H-cyclopentane[α]phenanthrèn-3-ol (5) and three steroids: β-sitosterol (6), stigmasterol (7) and stigmasterol 3-O-β-D-glucopyranoside (8). Their structures were elucidated on the basis of spectroscopic analysis and by comparison of their spectral data with those reported in the literature. To the best of our knowledge, all these compounds were isolated for the first time from the Leplaea mayombensis. The antimicrobial studies showed that isolated compounds exhibit antimicrobial activity with inhibition zone diameters varying from 0.00 ± 0.00 to 29.00 ± 0.00 mm on both bacteria and fungi. 9,10-cyclopropyl-(3S,5R,8R,13R,14S,17R) )-4,4,13,14,17-pentamethyl-l7-((2R,5S,6R)-5,6,7-trihydroxy-6-methylheptan-2-yl)-hexadecahydro-1 H-cyclopentane[α] phenanthrèn-3-ol (5) was the most active against Escherichia coli (28.00±0.00 mm), Pseudomonas sp (27.00±0.00 mm), Lactobacillus acidophilus (29.00±0.00 mm), Streptococcus pneumonia (23.00±0.00 mm) and Serratia entomophili (29.00±0.00 mm), C. albicans (12±0.00 mm), and T. viridae (13±0.00 mm) The results from this study support the conclusion that L. mayombensis contain many classes of antimicrobial compounds and therefore justify their traditional usage in the treatment of infectious diseases.

ABSTRACT

Aim: The role of Kinases in cancer onset and progression has made kinases a target for the control of some cancers. Recent discoveries that kinases are most effectively inhibited by small molecules have also resulted in an increased search for small molecule kinase inhibitors. Cycloartanes are small molecules found in many medicinal plants including the Jamaican Ball Moss (Tillandsia recurvata). Recent studies on T. recurvata have demonstrated that it possesses anticancer activity. Cycloartane-3,24,25- triol, an analog of a cycloartane identified in Ball moss was also shown to have inhibitory activity against MRCKα kinase. This study was as such set up to determine the MRCKα/β kinase inhibition activity of other cycloartanes in Ball Moss and their analogs. MRCKα/β kinases has been identified as an important kinase implicated in cancer onset and progression and as such a potential drug target. Methodology: Kinase inhibition activity of 6 cycloartanes was investigated using the ligand-kinase binding assay. The WST-1 reagent assay was also used to determine the antiproliferation activity of the cycloartanes against some prostate and breast cancer cell lines. Results: Cycloart-23-ene-3,25-diol (1), Cycloartane-3,24,25-triol (2), Cycloart-25-ene- 3,24-diol (3), 3,23-Dioxo-9,19-cyclolanost-24-en-26-oic acid (4), 24,25- Dihydroxycycloartan-3-one (5) inhibited the MRCKα kinase with Kd of 0.21 μM, 0.25μM, 0.36 μM, 3.0 μM and 2.1 μM respectively. Hydroxycycloart-23-en-3-one,25, (6) showed no inhibition against the MRCKα kinase. Compounds 1, 3, 4, 5 inhibited the MRCKβ kinase with Kd of 4.7 μM, 1.10 μM, 3.2 μM and 9.8 μM, respectively. Three of the six cycloartanes exhibited antiproliferation activity against two prostate and breast cancer cell lines each. Conclusion: Cycloart-23-ene-3,25-diol (1) showed the most promising activity against the MRCKα/β kinase out of the 6 cycloartanes screened demonstrating an interesting structure activity relationship profile when compared with the other molecules. Cycloart- 23-ene-3,25-diol (1) deserves further studies to determine its in vivo activity as well.

ABSTRACT

The hepatoprotective activity of the ethanol extract of Astragalus kahiricus (Fabaceae) roots against ethanol-induced liver apoptosis was evaluated and it showed very promising hepatoprotective actions through different mechanisms. The extract counteracted the ethanol-induced liver enzymes leakage and glutathione depletion. In addition, it demonstrated anti-apoptotic effects against caspase-3 activation and DNA fragmentation that were confirmed by liver histopathological examination. Moreover, the phytochemical study of this extract led to the isolation of four cycloartane-type triterpenes identified as astrasieversianin II (1), astramembrannin II (2), astrasieversianin XIV (3), and cycloastragenol (4). The structures of these isolates were established by HRESI-MS and 1D and 2D NMR experiments. The antimicrobial, antimalarial, and cytotoxic activities of the isolates were further evaluated, but none of them showed any activity.

ABSTRACT

The biological activitites of Dikamaliartane-A, a cycloartane isolated from gum resin Dikamali of Gardenia gummifera/Gardenia lucida was screened for some pharmacological actions. The study was carried out using albino mice (20-25gr). It reduced locomotor activity and potentiated pentobarbitone-induced sleeping time in mice indicating Central Nervous System depressant activity. It protected mice from strychnine and electro shock–induced convulsions indicating that it has anti-convulsant activity. All these activities were statistically significant. The LD50 (Lethal Dose) was carried out in mice according to Organization for Environmental Cooperation and Development (OECD) Guidelines 423. The LD50 was tested in three mices for each dose with doses from 5mg/kg, 50mg/kg, 300mg/kg and 2000mg/kg. The LD50 was found to be 500mg/kg.
