line (HEK-293) has been studied. 2-DAT-J (1) showed significant in vitro activity against breast cancer cell line at a concentration of 20 μM and 10 μM in MCF-7 and MDA-MB-231 respectively. Few noveltaxoids were derived (7, 8 and 10–13) from the naturally occurring 2-DAT-J (1) and screened for their anticancer activity. The structure–activity relationship studies indicated that the cinnamoyl group
