Fatostatin (125B11) 是SREBP活化的特异性抑制剂,可抑制 SREBP-1 和 SREBP-2 的活化。Fatostatin 与 SCAP (SREBP裂解激活蛋白) 结合,抑制 SREBPs 的 ER-Golgi 易位。Fatostatin 降低了细胞中成脂基因的转录。Fatostatin 具有抗肿瘤作用,能降低ob/ob小鼠的高血糖。
生物活性 | Fatostatin (125B11), a specific inhibitor ofSREBP activation, impairs the activation of SREBP-1 and SREBP-2. Fatostatin binds to SCAP (SREBP cleavage-activating protein), and inhibits the ER-Golgi translocation of SREBPs. Fatostatin decreases the transcription of lipogenic genes in cells. Fatostatin possesses antitumor properties, and lowers hyperglycemia inob/obmice[1][2]. |
体外研究 (In Vitro) | Fatostatin (125B11) (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 inhibits insulin-induced adipogenesis of 3T3-L1 cells[1]. Fatostatin directly binds SCAP and blocks its ER-to-Golgi transport with IC50of 2.5 and 10 μM in mammalian cells.
Cell Proliferation Assay[1] Cell Line: | DU-145 cells | Concentration: | 0.1, 1 μM | Incubation Time: | 3 days | Result: | Impaired the IGF1-induced growth at an IC50of 0.1 μM. |

体内研究 (In Vivo) | Fatostatin (125B11) (30 mg/kg; 150 μL; i.p. injection; daily for 28 days) reduces adiposity, ameliorated fatty liver by reducing triglyceride (TG) storage, and lowered hyperglycemia inob/obmice[2].
Animal Model: | Four-to-five-week-old homozygous male obese (ob/ob) mice (C57BL/6J)[2] | Dosage: | 30 mg/kg; 150 μL | Administration: | i.p. injection; daily for 28 days | Result: | Blocked increases in body weight, blood glucose, and hepatic fat accumulation in obeseob/obmice, even under uncontrolled food intake. |
