A series of seventeen novel analogs of ursolic and oleanolic acid were synthesized (60–98 %), and evaluated for their anti-cancer potential against a panel of eight human cancer cell lines. Compounds (3–10) showed comparable or better activities than their respective parent compounds against SiHa and HeLa (Cervix), A-549 (Lung), and IMR-32 (Neuroblastoma)(More)
Nardostachys jatamansi DC. is a highly reputed Medhya and Nootropic (Learning and Memory) Ayurvedic medicinal plant. Its use as herbal medicine singly and as an ingredient of multi-herbal formulations is fast increasing. In order to authenticate and evaluate it quantitatively, its standardization is highly warranted with respect to a reliable marker. In(More)
Some novel chemically modified frameworks of ursolic acid have been designed and synthesized. The key step was the cycloaddition of azidopropyl-3β-hydroxy-urs-12-en-28-oate with the appropriate C28 propargyl esters of ursolic, corosolic, asiatic, oleanolic, and betulinic acid under Click reaction conditions, and the products were obtained in 74-84% yields.(More)
Ring-C of oleanolic acid was chemically modified by treating with NBS under a variety of experimental conditions. The structures of the synthesized compounds were established by spectral analysis ((1)H &(13)C NMR and Mass). All the compounds were evaluated against a panel of five human cancer cell lines by using MTT assay. Among the tested compounds, 2 and(More)
Ursolic acid (1), a natural pentacyclic triterpenic acid, afforded a variety of ring-C transformed products (5-11) when treated with N-bromosuccinimide under the influence of a range of protective groups and solvents. The synthesized compounds have been evaluated for cytotoxic activity against prostate PC 3, leukemia THP 1, cervical Hela and lung A-549(More)
