Biological Activity

Description Fatostatin HBr is an inhibitor of sterol regulatory element binding protein (SREBP). It impairs the activation of SREBP-1 and SREBP-2.
Targets
SREBPs [1]
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].

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    CHO-K1 cells

  • Concentrations

    20 μM

  • Incubation Time

    20 h

  • Method

    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.
Animal Study:[1]
  • Animal Models

    Obese (ob/ob) mice (C57BL/6J background)

  • Dosages

    30 mg/kg

  • Administration

    i.p.
