Synthesis and cytotoxic activity of steroid-anthraquinone hybrids
摘要:
Synthesis of cytotoxic steroidal derivatives containing a quinone moiety is described. The synthetic strategy is based on an unsual A + CD --> ABCD Diels-Alder approach which generates 9 beta-H cholestane analogs. The adducts formed are efficiently aromatized in basic media to give steroid-anthaquinones hybrids showing interesting cytotoxic activity on four tumor cell lines. (C) 1997 Elsevier Science Ltd.
