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 (DIPG) 相关,这些疾病与儿科患者的预期寿命严重缩短有关。ALK2 还被证明通过调节铁调素水平和影响慢性病贫血在铁代谢中发挥重要作用。因此,选择性抑制 ALK2 已成为治疗多种疾病的有前景的策略。在此,我们报告发现了一种新型吡唑并嘧啶系列作为高效、选择性和口服生物可利用的 ALK2 抑制剂。
