Synthesis and Antitumor Activity of Dehydroepiandrosterone Derivatives on Es-2, A549, and HepG2 Cells in vitro
摘要:
A series of dehydroepiandrosterone derivatives containing an acid ester was synthesized and evaluated for their antitumor activity on ES‐2, A549, and HepG2 cells by the MTT assay. Most compounds showed antitumor activity, while compounds 1c, 2i, and 2o exhibited more potential inhibitory effects compared with dehydroepiandrosterone on ES‐2 cells, A549 cells, and HepG2 cells, respectively.
