Description

Description générale

A cell-permeable diarylthiazole compound that prevents the cellular activation of the SREBP-1/2 (Sterol Regulatory Element Binding Proteins 1/2) precursors to the active nuclear forms (>95% inhibition at 20 µM in CHO-K1 cells) by blocking SREBPs-SCAP (SREBP Cleavage-Activating Protein) ER to Golgi translocation with little effect against the transcription activity of the mature SREBPs. Binding studies employing recombinant SCAP truncation constructs reveal that Fatostatin targets SCAP between aa 448 to 767 in a reversible manner and is of no effect against SREBP-SCAP interaction. Fatostatin effectively suppresses SREBPs-dependent cellular functions in vitro, such as insulin-induced 3T3-L1 adipogenesis (complete inhibition at ≤20 µg/ml) and IGF1-dependent DU-145 proliferation (IC₅₀ = 100 nM), and exhibits in vivo efficacy in lowering blood glucose level (by 70%) and body weight (by 12%) of ob/ob mice over a 28-day treatment period (30 mg/kg daily i.p.) without affecting animal food intake or apparent adverse effects.
