Fatostatin (hydrobromide)

Fatostatin hydrobromide (125B11 hydrobromide), a specific inhibitor of SREBP activation, impairs the activation of SREBP-1 and SREBP-2. Fatostatin hydrobromide binds to SCAP (SREBP cleavage-activating protein), and inhibits the ER-Golgi translocation of SREBPs. Fatostatin hydrobromide decreases the transcription of lipogenic genes in cells. Fatostatin hydrobromide possesses antitumor properties, and lowers hyperglycemia in ob/ob mice^[1][2]. In Vitro: Fatostatin hydrobromide (125B11 hydrobromide) (0.1-1 μM; 3 days) inhibits the androgen-independent prostate cancer cell proliferation (IC₅₀=0.1 μM) in an independent of the known IGF1-signaling pathway. Fatostatin hydrobromide inhibits insulin-induced adipogenesis of 3T3-L1 cells^[1]. In Vivo: Fatostatin hydrobromide (125B11 hydrobromide) (30 mg/kg; 150 mL; i.p.; daily for 28 days) reduces adiposity, ameliorates fatty liver by reducing triglyceride (TG) storage, and lowers hyperglycemia in ob/ob mice^[2].
