fibrodysplasia ossificans progressiva, making it an attractive target for therapeutic intervention. We synthesized a new series of bicyclic pyrazoles and evaluated their mutant ALK2 enzyme inhibitory activities, leading to the identification of 8 as the most potent inhibitor. This compound showed moderate microsomal metabolic stability and human ether-a-go-go related gene (hERG) safety. In C2C12 cells
突变激活素受体样激酶 2 (ALK2) 与骨化纤维发育不良的发病机制有关,使其成为治疗干预的有吸引力的目标。我们合成了一系列新的双环
吡唑并评估了它们的突变 ALK2 酶抑制活性,从而确定8是最有效的
抑制剂。该化合物表现出中等的微粒体代谢稳定性和人类 ether-a-go-go 相关
基因 (hERG) 安全性。在携带突变 ALK2 (R206H) 的 C2C12 细胞中,8有效抑制了骨形态发生蛋白 (
BMP) 诱导的碱性
磷酸酶活性。
