ALDH1a2 Inhibitors

Alternative Name: Inhibitors of Testicular Retinoic Acid Biosynthesis

Description: ALDH1A2 is an enzyme involved in testicular retinoic acid biosynthesis, that if blocked can arrest spermotogenesis. Small molecule inhibitors of ALDH1A2 are being developed as long-term oral, reversible male contraceptives, based on earlier work on bisdichloroacetyldiamines (BDADs).
