General Comments
17β-HSD2 catalyses the interconversion of estradiol <-> estrone and testosterone <-> androstenedione.
Pharmacological inhibition of 17β-HSD2 is being investigated as a novel mechanism for the treatment of osteoporosis. Inhibiting 17β-HSD2 is predicted to increase estradiol and testosterone levels in bone, and to thereby simultaneously inhibit osteoclast-mediated bone resorption and increase bone formation by osteoblasts.
