Dihydrotestosterone derivatives: Relative binding affinity versus affinity purification

Article abstract of DOI:10.1016/0039-128X(91)90020-V

Mono esters of a homologous series of diacids of dihydrotestosterone were synthesized and converted to the corresponding n-butyl amides. The relative binding affinities of these amides to androgen receptor were compared with the degree of purification of rat prostate androgen receptor by affinity columns prepared by linking the steroidal acid to ammo Sepharose. There was good correlation between binding of the amide model to androgen receptor and the extent of purification by the affinity resin.
