The study from April 2010 examined the effects of curcumin and its derivatives on the enzyme 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3), which is important for testosterone production. Curcumin inhibited the enzyme with IC50 values of 9.0 ± 1.0 µM in rat Leydig cells, 2.3 ± 1.2 µM in rat testis microsomes, and 67.3 ± 11.9 µM in human testis microsomes. One derivative, compound C3, was significantly more effective, with an IC50 of 0.1 µM against human 17β-HSD3. The results indicated that curcumin derivatives could be more potent inhibitors of 17β-HSD3 than curcumin itself, with varying effectiveness between species, suggesting their potential use in anti-androgenic therapies.
