disease. Thus, selective inhibition of ALK2 has emerged as a promising strategy for the treatment of multiple disorders. Herein, we report the discovery of a novel pyrazolopyrimidines series as highly potent, selective, and orally bioavailable inhibitors of ALK2. Structure-based drug design and systematic structure–activity relationship studies were employed to identify potent inhibitors displaying high
激活素受体样激酶 2 (ALK2) 是一种跨膜激酶受体,介导 TGF-β 超家族成员的信号传导。ALK2 的异常激活与罕见的遗传性疾病进行性骨化性纤维发育不良 (FOP) 和弥漫性内源性脑桥胶质瘤 (DI
PG) 相关,这些疾病与儿科患者的预期寿命严重缩短有关。ALK2 还被证明通过调节
