exhibited moderate in vitro anticanceractivity. Chemical transformation of 2 led to significant improvement in the activity in derivative 8 and 15 against HepG2 (human hepatocellular carcinoma), MCF-7 (breast adenocarcinoma) cell lines. The compounds 8 and 15 were also capable of cell cycle arrest and caspasedependentapoptosis in HepG2 cell lines. These iridoid derivatives hold promise for developing
