Abstract

Several Steroids (abiraterone, prednisone, testosterone, Cholesterol) and the Bcl-2 Inhibitor bexarotene were used as starting Materials to synthesize iperazinyl-spacered rhodamine B conjugates. The conjugates were screened for their cytotoxicity in SRB assays against several human tumor cell lines and found to be active in a low μM to nM range. The conjugate derived from testosterone held an EC50 = 59 nM against MCF-7 tumor cells and acted mainly by necrosis. The prednisone conjugate, however, was less cytotoxic but acted mainly by Apoptosis and held a moderate selectivity against MCF-7 tumor cells.
