Disease relevance of Srd5a1

  • Furthermore, some of these potent P450(17) alpha inhibitors (27-29) are also powerful inhibitors of steroid 5 alpha-reductase, and others (17 and 19) appear to exhibit strong antiandrogenic activity in cultures of the LNCaP human prostatic cancer cell line [1].
  • BACKGROUND: Steroid 5 alpha-reductase is implicated in the pathogenesis of benign prostatic hyperplasia (BPH) [2].
