Pharmacology of oleanolic acid and ursolic acid.
Oleanolic acid and ursolic acid are triterpenoid compounds that exist widely in food, medicinal herbs and other plants. This review summarizes the pharmacological studies on these two triterpenoids. Both oleanolic acid and ursolic acid are effective in protecting against chemically induced liver injury in laboratory animals. Oleanolic acid has been marketed in China as an oral drug for human li...
متن کامل[Synthesis and anti-tumor activity of oleanolic acid derivatives].
Thirteen novel oleanolic acid (OA) derivatives were designed and synthesized with modification at positions of C-3, C-12 and C-28 of OA. Their structures were confirmed by MS, 1H NMR and elemental analysis. Their in vitro cytotoxicities against various cancer cell lines (SGC7901, MCF-7 and A549) were evaluated by MTT assay. The results indicated that the tested derivatives were found to have st...
متن کاملEnhancement of Platelet Aggregation by Ursolic Acid and Oleanolic Acid
The pentacyclic triterpenoid ursolic acid (UA) and its isomer oleanolic acid (OA) are ubiquitous in food and plant medicine, and thus are easily exposed to the population through natural contact or intentional use. Although they have diverse health benefits, reported cardiovascular protective activity is contentious. In this study, the effect of UA and OA on platelet aggregation was examined on...
متن کاملAnti-tuberculosis activity of oleanolic and ursolic acid isolated from the dichloromethane extract of leaves from Duroia macrophylla
Introduction Tuberculosis a major cause of death worldwide, is an infectious disease caused by Mycobacterium tuberculosis. An increase in drug-resistant tuberculosis cases and the emergence of additional resistant strains and coinfections with HIV has stimulated the search for and development of new anti-TB drugs [1]. The wide variety of natural products chemical structures plays a major role o...
متن کاملAntimicrobial Activity of Oleanolic and Ursolic Acids: An Update
Triterpenoids are the most representative group of phytochemicals, as they comprise more than 20,000 recognized molecules. These compounds are biosynthesized in plants via squalene cyclization, a C30 hydrocarbon that is considered to be the precursor of all steroids. Due to their low hydrophilicity, triterpenes were considered to be inactive for a long period of time; however, evidence regardin...
