Biochem/physiol Actions

SK33, a trifluoromethylated enobosarm analog, is a cell and brain penetrant, tissue selective and highly potent anti-androgen that reduces androgen receptor (AR) transcriptional activity. SK33 induces cell cycle arrest at G1 phase. It exhibits increased efficacy against acquired anti-androgen resistance prostate cancer cells.

D Alwyn Dart et al.
Molecular cancer therapeutics, 17(9), 1846-1858 (2018-06-14)
Prostate cancer often develops antiandrogen resistance, possibly via androgen receptor (AR) mutations, which change antagonists to agonists. Novel therapies with increased anticancer activity, while overcoming current drug resistance are urgently needed. Enobosarm has anabolic effects on muscle and bone while
