Abstract
5 alpha-Androstan-3 alpha,17 beta-diol (3 alpha-diol) is a well known metabolite of dihydrotestosterone (DHT) and the concentration of its g lucuronide in serum is' looked upon as a marker of DHT activity in ski n and prostate. The data in this communication show that 3 alpha-diol is a potent agonist of the human and canine prostatic SHBG-[SHBG recep tor]. It causes a robust rise in intracellular cAMP within minutes; th e 1/2 max. response occurs at a concentration equal to its concentrati on in male plasma. Estradiol is the only other agonist in this system. All other steroids that bind to SHBG are antagonists.
