Structure-activity relationship and crystallographic data revealed that quinazolinone-containing fragments flip between two distinct modes of binding to activin receptor-like kinase-2 (ALK2). We explored both binding modes to discover potent inhibitors and characterized the chemical modifications that triggered the flip in binding mode. We report kinase selectivity and demonstrate that compounds of
构效关系和晶体学数据表明,含有喹唑啉酮的片段在两种不同的与激活素受体样激酶-2 (ALK2) 结合的模式之间翻转。我们探索了两种结合模式以发现有效的抑制剂,并表征了触发结合模式翻转的化学修饰。我们报告激酶选择性并证明该系列化合物可调节癌细胞中的 ALK2。这些抑制剂是发现更先进的 ALK2 抑制剂的有吸引力的起点。
