Antimicrobial activity of some pentacyclic triterpenes and their synthesized 3-O-lipophilic chains.
نویسندگان
چکیده
The major metabolites of Diopsyros melanoxylon viz. amyrins and ursolic acid and their lipophilic 3-O-fatty acid ester chains (C12-C18), which are synthesized now under mild esterification conditions in excellent yields (80-95%), were evaluated for their antimicrobial activity against a series of Gram positive and Gram negative bacteria. Significantly these compounds were found to exhibit potent activity against Gram negative bacteria Pseudomonas syringae (ATCC #13457) and fairly good activity against Gram positive bacteria, Bacillus sphaericus (ATCC #14577) and Bacillus subtilis (ATCC #6051).

The ethyl acetate partition of dried methanolic extract of aerial parts of Euphorbia microsciadia (Euphorbiaceae) afforded three pentacyclic triterpenes, betulinic acid (1) from lupane type, oleanolic acid (2) from oleane type and ursolic acid (3) from ursane type triterpenes that are reported for the first time in this plant. These three compounds were structurally compared through their mass ...

متن کاملInhibition of Human Neutrophil Elastase by Pentacyclic Triterpenes
SCOPE Inhibiting human neutrophil elastase (HNE) is a promising strategy for treating inflammatory lung diseases, such as H1N1 and SARS virus infections. The use of sivelestat, the only clinically registered synthesized HNE inhibitor, is largely limited by its risk of organ toxicity because it irreversibly inhibits HNE. Therefore, potent reversible HNE inhibitors are promising alternatives to s...
متن کاملPentacyclic triterpenes from the stem bark of Mimusops elengi L.
A new farnane-type pentacyclic triterpene, farnan-2-one-3 beta-ol (mimusopfarnanol), was isolated from the stem bark of Mimusops elengi L. along with the known triterpenoids, farnan-3-one, olean-18-en-2-one-3-ol and lup-20 (29)-en-3 beta-ol and their structures have been characterized on the basis of spectral data analyses and chemical reactions.

Pentacyclic triterpenes are produced by arrangement of squalene epoxide. These compounds are extremely common and are found in most plants. There are at least 4000 known triterpenes. Many triterpenes occur freely but others occur as glycosides (saponins) or in special combined forms. Pentacyclic triterpenes have a wide spectrum of biological activities and some of them may be useful in medicine...
