Triterpenoids from Dysoxylum genus and their biological activities
Al Arofatus Naini,Tri Mayant,Unang Supratman 대한약학회 2022 Archives of Pharmacal Research Vol.45 No.2
This study aims to analyze the ethnobotanical,chemical, and biological activities of triterpenoid compoundsisolated from the Dysoxylum genus of the Meliaceaefamily between 1974 and 2021. The species are mainly distributedin Africa, Asia, and Australia, and used as a traditionalmedicine to treat various diseases. Triterpenoid wasfi rst isolated in 1976 and as tetranortriterpenoid or limonoid,it was named dysobinin. Several studies were conducted formore than 40 years on the plants’ stems, bark, and leaves,where approximately 279 triterpenoid compounds fromseveral groups such as dammarane, nortriterpenoid, oleanane,lupane, tirucallane, cyclolanostane, or cycloartane,glabretal, and cycloapoeuphane-types were isolated withsome synthetic products. In addition, the hypothetical routeof triterpenes biosynthesis from this genus was identifi ed,and tirucallane-type were reported to be 37.6% of the totalcompounds. The anti-malarial, anti-feedant, antimicrobial,anti-infl ammatory, antioxidant, vasodilative eff ect, anti-viral,cortisone reductase, and cytotoxic activities of the extractwere also evaluated. The results showed the necessity ofusing the triterpenoid compounds from the Dysoxylum genusin traditional medicine and the discovery of new drugs.

Seven flavonoid compounds, kaempferol (1), quercetin (2), quercetin-3-O-b-D-glucopyranoside (3), kaempferol-3-O-b-D-glucopyranoside (4), kaempferol-3-O-a-L-rhamnoside (5), quercetin-3-O-sophoroside (6) and quercetin-3-O-rutinoside (7), were isolated from the methanolic extract of leaves of Kalanchoe prolifera. Compounds 1-7 were isolated for first time from this plant. These compounds were evaluated their cytotoxic activity against P-388 murine leukimia cells in vitro. Among those compounds kaempferol (1) and quercetin (2) showed strongest cytotoxic activity with IC50 values of 4.45 ? 0.05 and 6.28 ? 0.02 mg/mL, respectively.

Six dammarane-type triterpenoids, dammar-24-en-3b-ol (1), 3b-epicabraleahydroxy lactone (2), (E)-25-hydroperoxydammar-23-en-3b,20-diol (3), dammar-24-en-3b,20-diol (4), 3b-acetyl-20S,24S-epoxy-25-hydroxy- dammarane (5), and 3b-epiocotillol (6) were isolated from the methanolic extract of the bark of Aglaia elliptica. The chemical structure were identified on the basis of spectroscopic evidence and by comparison with those spectra previously reported. Compounds 1 - 6 were isolated first time from this plant. Compounds 1 - 6, along with a known synthetic analog, cabraleone (7) were evaluated their cytotoxic activity against P-388 murine leukimia cells in vitro. Among those compounds 3b-acetyl-20S,24S-epoxy-25-hydroxydammarane (5) showed strongest cytotoxic activity with IC50 value of 8.02 ? 0.06 mM.

A new havanensin-type limonoid, 16β-hydroxydysobinin (1), along with four known limonoids (2–5), have been isolated from the seeds of Chisocheton macrophyllus. The chemical structure of the new compound was determined by referencing spectroscopic data, and by comparison to those related spectra previously reported. Each compound was evaluated for their cytotoxic efects against Michigan Cancer Foundation-7 (MCF-7) breast cancer cells and display no signifcant activity.

Five sesquiterpenoids, 7-epi-eudesm-4(15)-ene,1β,6α-diol (1), 7-epi-eudesm-4(15)-ene,1β,6α-diol (2), saniculamoid D (3), aphanamol I (4), and 4β,10α-dihydroxyaromadendrane (5), were isolated from the stem bark of Aglaia grandis. The compounds’ (1-5) chemical structures were identified by spectroscopic data including, IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1H COSY), and HRTOFMS, as well as by comparing with the previously reported spectral data. Therefore, this study described the structural elucidation of compounds 1-5 and evaluated their cytotoxic effects against Hela cervical and B16F10 melanoma cells for the first time, but no significant result was discovered.
