SKU: S9785
Availability: InStock
Rating: 5 (11 reviews)

Cat.No.S9785

Fatostatin (125B11), a diarylthiazole derivative, is a specific inhibitor of Sterol regulatory element binding proteins (SREBPs) activation. This compound binds to SCAP (SREBP cleavage-activating protein), and inhibits the ER-Golgi translocation of SREBPs. It suppresses growth and enhances apoptosis in cancer cells.

2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	SREBP ^[1]
In vitro	Fatostatin impairs the activation process of sterol regulatory element binding proteins (SREBPs), thereby decreasing the transcription of lipogenic genes in cells. This compound inhibits the ER-Golgi translocation of SREBPs through binding to their escort protein, the SREBP cleavage-activating protein (SCAP), at a distinct site from the sterol-binding domain.^[1]
In vivo	Fatostatin blocks increases in body weight, blood glucose, and hepatic fat accumulation in obese ob/ob mice, even under uncontrolled food intake. This compound may serve as a tool for gaining further insights into the regulation of SREBP.^[1]
