A series of substituted 5alpha-androstan-17beta-ols was synthesized and evaluated for their potential use in the development of a prostate imaging agent. The ability of the synthesized compounds to compete with [3H]-5alpha-dihydrotestosterone for rat prostate androgen receptor protein served as the screening assay. For 3-substituted derivatives, the order of binding to the androgen receptor protein
