5alpha-dihydro-11-keto Testosterone-d3

5alpha-dihydro-11-keto Testosterone-d3 is intended for use as an internal standard for the quantification of 5alpha-dihydro-11-keto testosterone (Cay-20200) by GC- or LC-MS. 5alpha-dihydro-11-keto Testosterone is a metabolite of 11beta-hydroxyandrostenedione and 11beta-hydroxytestosterone that has been shown to act as a full androgen receptor agonist with equal potency as that of dihydrotestosterone (Cay-15874). The androgenic activity of 5alpha-dihydro-11-keto testosterone has been implicated in contributing to the androgen pool that drives castration-resistant prostate cancer cells.Formal Name: (5alpha,17beta)-17-hydroxy-androstane-3,11-dione-d3.
