genomic landscape surrounding DIPG has revealed that activin receptor-like kinase-2 (ALK2) constitutes a potential target for therapeutic intervention given its dysregulation in the disease. We adopted an open science approach to develop a series of potent, selective, orally bioavailable, and brain-penetrant ALK2 inhibitors based on the lead compound LDN-214117. Modest structural changes to the C-3, C-4
目前尚无批准用于弥散性桥脑神经胶质瘤(DIPG)的有效化学治疗药物,弥漫性桥脑神经胶质瘤是一种侵袭性小儿癌,位于脑干桥区域。放射疗法是有益的,但不是治愈的,病情一律致命。对DIPG周围的基因组格局的分析表明,鉴于激活素受体样激酶2(ALK2)在疾病中的失调,它构成了治疗干预的潜在靶标。我们采用了开放式科学方法,以基于铅化合物LDN-214117的方式开发了一系列有效的,选择性的,口服生物利用的和脑渗透性的ALK2抑制剂。对核心吡啶环的C-3,C-4和C-5位置取代基进行适度的结构变化即可得到化合物M4K2009,M4K2117和M4K2163均具有出色的效能,选择性和/或血脑屏障(BBB)渗透特性。强大的体内药代动力学(PK)特性和耐受性将这些抑制剂标记为适合在DIPG原位模型中进一步开发和评估的高级临床前化合物。
