castrated hamsters treated with dihydrotestosterone. The four compounds bind to the androgen receptor with different relative binding affinity (RBA). Compound 9d having a logP of 4.17 showed the highest RBA>100% as compared to compound 9a having a logP of 2.92 which exhibited a RBA of only 2.85%. These data show a very good correlation between the lipophilicity of these compounds represented by logP and

cell lines).Determination of the cytotoxic effect of the steroids with one or two &agr;,&bgr;‐unsaturated carbonyls.The steroids with 4‐fluorinatedbenzoicacid ester at C‐21 were cytotoxic against SKLU‐1 cell line. ABSTRACT Four series of pregnenolone derivatives having one or two &agr;,&bgr;‐unsaturated carbonyls and an ester moiety at C‐21 or C‐3 were synthetized to compare their cytotoxicity effect
