hydrogen-bond acceptor that drives potency and selectivity in addition to favorable ADME properties. Brigatinib displayed low nanomolar IC50s against native ALK and all tested clinically relevant ALK mutants in both enzyme-based biochemical and cell-based viability assays and demonstrated efficacy in multiple ALK+ xenografts in mice, including Karpas-299 (anaplastic large-cell lymphomas [ALCL]) and H3122 (NSCLC)
在棘皮动物微管相关蛋白样4(EML4)-间变性淋巴瘤激酶阳性(ALK +)非小细胞肺癌(NSCLC)的治疗中,ALK激酶结构域内的继发突变已成为对二者的主要耐药机制第一代和第二代ALK抑制剂。该报告描述了一系列基于2,4-二芳基氨基嘧啶的有效和选择性ALK抑制剂的设计和合成,这些抑制剂最终可鉴定出临床研究候选药物brigatinib。Brigatinib的独特结构特征是氧化膦,这是一种被忽视但新颖的氢键受体,除了具有良好的ADME性能外,还可以提高效价和选择性。Brigatinib展示了低纳摩尔IC 50在基于酶的生化和基于细胞的活力测定中均针对天然ALK和所有经过测试的临床相关ALK突变体,并在小鼠的多种ALK +异种移植物中证明了功效,包括Karpas-299(间变性大细胞淋巴瘤[ALCL])和H3122( NSCLC)。Brigatinib代表了迄今为止临床上最先进的含氧化膦药物候选
