Homogeneous suspension

CMC-NA

≥5mg/ml

Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Fatostatin HBr is an inhibitor of sterol regulatory element binding protein (SREBP). It impairs the activation of SREBP-1 and SREBP-2.
in vitro	Fatostatin inhibits the insulin-induced adipogenesis of 3T3-L1 cells and the serum-independent growth of human androgen-independent prostate cancer (DU145) cells. Fatostatin blocks the activation of SREBPs in cells in tissue culture^[1]. Fatostatin suppresses cell proliferation and anchorage-independent colony formation in both androgen-responsive LNCaP and androgen-insensitive C4-2B prostate cancer cells. Fatostatin also reduced in vitro invasion and migration in both cell lines. Further, fatostatin causes G2/M cell cycle arrest and induces apoptosis by increasing caspase-3/7 activity and the cleavages of caspase-3 and PARP^[2].
in vivo	Fatostatin blocks increases in body weight, blood glucose, and hepatic fat accumulation in obese ob/ob mice, even under uncontrolled food intake^[1]. Fatostatin significantly inhibits subcutaneous C4-2B tumor growth and markedly decreases serum PSA level compared to the control group^[2].

	実験の流れ	On day 0, CHO-K1 cells are plated out onto a 96-well plate in medium A. On day 2, the cells are transiently cotransfected with pCMV-PLAP-BP2(513–1141), pCMV-SCAP, and pAc-β-gal, using Lipofectamine reagent. After incubation for 5 hr, the cells are washed with PBS and then incubated in medium B, in the absence or presence of fatostatin (20 μM) or sterols (10 μg/mL cholesterol and 1 μg/mL 25-hydroxycholesterol). After 20 hr of incubation, an aliquot of the medium is assayed for secreted alkaline phosphatase activity. The cells in each well are lysed and used for measurement of β-galactosidase activities. The alkaline phosphatase activity is normalized by the activity of β-galactosidase.
