ファトスタチン(Fatostatin)(125B11)は、ステロール調節エレメント結合タンパク質(SREBP)活性化の特異的阻害剤であり、SREBP-1とSREBP-2の両方の活性化を阻害する。ファトスタチンは、SCAP(SREBP切断活性化タンパク質)の発生を阻害し、活性化のためにSREBPがゴルジ体に輸送されるのを妨げ、それによって脂質およびコレステロールの生合成に関与する遺伝子の転写を減少させる。ファトスタチンは、AKT/mTORC1/GPX4シグナル伝達経路を阻害し、フェロプターシスを誘導することができる。
In vitroでは、U87、T98G、MDA-MB-453、Jurkat T細胞をファトスタチン(5μM)で24時間または48時間処理すると、紡錘体損傷と分裂停止が誘導され、全ての細胞がG2/M期で阻害された。CHO細胞のファトスタチン(0~20μM)処理は、用量依存的にHMG-CoA合成酵素(HMGCS 1)の発現を阻害し、細胞内SREBPプロセッシングを阻害した。
In vivoでは、ファトスタチン(15 mg/kg)を腹腔内注射で42日間投与すると、C4-2B腫瘍を皮下に移植したマウスの腫瘍増殖が有意に抑制され、腫瘍細胞の増殖指数(Ki67状態)、血清前立腺特異抗原(PSA)レベル、SREBP下流遺伝子のmRNAおよびタンパク質レベルが低下した。肥満ob/obマウスにファトスタチン(30mg/kg)を28日間腹腔内投与すると、体重、血糖値、肝脂肪蓄積の増加が抑制された。
