渥曼青霉素

简介

渥曼青霉素是有效的特异性的磷脂酰肌醇3-激酶(PI3-K)抑制剂，IC50为2-4 nM。可抑制自噬体的形成，也有效抑制DNA-PK/ATM，IC50分别为16 nM 和 150 nM。

用途

一种PI3Ks和PLK1的特异性共价抑制剂。Wortmannin, a steroid metabolite of the fungi Penicillium funiculosum, Talaromyces (Penicillium) wortmannii, is a specific, covalent inhibitor of phosphoinositide 3-kinases (PI3Ks) and Polo-Like kinase 1 (PLK1). It has an in vitro inhibitory concentration (IC50) of around 5 nM, making it a more potent inhibitor than LY294002, another commonly used PI3K inhibitor. Wortmannin has also been reported to inhibit members of the polo-like kinase family with IC50 in the same range as for PI3K.
