generation ALK inhibitor, is widely prescribed for ALK-positive NSCLC in clinic. Resistance to crizotinib and other ALK inhibitors has been problematic. Addressing resistance, here we describe discovery and development of a novel, proprietary spirocyclic diamine-substituted aryl phosphine oxide series of inhibitors, which led to the identification of WX-0593 (16a) as a potent ALK inhibitor. WX-0593 inhibited
在大约 5% 的 NSCLC 中,ALK 基因重排是致癌驱动因素。克唑替尼是第一代 ALK 抑制剂,临床上广泛用于 ALK 阳性 NSCLC。对克唑替尼和其他 ALK 抑制剂的耐药性一直存在问题。针对耐药性,我们在此描述了一种新型专有螺环二胺取代的芳基氧化膦系列抑制剂的发现和开发,从而将 WX-0593 (16a)鉴定为有效的 ALK 抑制剂。WX-0593在体外抑制 ALK 野生型和耐药突变体的活性,在克唑替尼耐药小鼠 PDX 模型中显示出很强的抗肿瘤活性。WX-0593目前正在进行II/III期临床试验。
