Cytotoxicity of these compounds and their derivatives (2, 5, and 6) was evaluated on HL-60 cells. Further studies revealed that acetyl eburicoic acid (5) was the most potent apoptosis inducer. Apoptosis was accompanied by both the activation of caspase-3 and the fragmentation of poly(ADP-ribose) polymerase-1 and was also associated with an early release of cytochrome c from the mitochondria.||URI:||http://hdl.handle.net/10553/50572||ISSN:||0163-3864||DOI:||10.1021/np049762o||Source:||Journal Of Natural Products[ISSN 0163-3864],v. 67 (12), p. 2008-2011|
