摘要：
A series of new heterocyclic derivatives of ursolic acid 1 were synthesized and evaluated for their anti-proliferative activity against AsPC-1 pancreatic cancer cells. Compounds 24-32, with an alpha,beta unsaturated ketone in conjugation with an heterocyclic ring in ring A have improved antiproliferative activities. Compound 32 is the most active compound with an IC50 of 1.9 mu M which is sevenfold more active than ursolic acid 1. Compound 32 arrests cell cycle in G1 phase and induces apoptosis in AsPC-1 cells with upregulation of p53, p21(waf1) and NOXA protein levels. (C) 2012 Elsevier Ltd. All rights reserved.
