Heat shock protein 90 is an emerging target for oncology therapeutics. Inhibitors of this molecular chaperone, which is responsible for the maintenance of a number of oncogenic proteins, have shown promise in clinical trials and represent a new and exciting area in the treatment of cancer. Heat shock protein 90 inhibitors have huge structural diversity, and here we present the lead identification of
热休克蛋白90是肿瘤治疗的新兴目标。这种分子伴侣的抑制剂负责维持许多致癌蛋白,已在临床试验中显示出希望,并代表了癌症治疗领域中一个崭新的令人兴奋的领域。热激蛋白90抑制剂具有巨大的结构多样性,在这里,我们介绍基于β-内酰胺和亚胺模板的新型抑制剂的先导鉴定。β-内酰胺5和亚胺12和18通过IC 50与热激蛋白90-α结合值分别为5.6μM,14.5μM和22.1μM。这些化合物表现出的结合亲和力将它们定位为基于β-内酰胺和亚胺模板设计未来热休克蛋白90抑制剂的先导化合物。
