potent AAK1 inhibitors with good druglike properties. Among these, compounds 43 and 58 showed very good efficacy in two neuropathic pain rat models and had excellent CNS penetration and spinal cord target engagement. Both compounds also exhibited favorable physicochemical and oral pharmacokinetic (PK) properties. Compound 58, a central pyridine isomer of BMS-986176/LX-9211 (4), was 4-fold more potent
最近的小鼠基因敲除研究将接头蛋白 2 相关激酶 1 (AAK1) 确定为治疗神经性疼痛的可行靶标。BMS-986176/LX-9211 ( 4 ) 作为一种高选择性、可穿透 CNS 且有效的 AAK1 抑制剂,已进入 II 期人体试验。在探索这种联芳基烷基醚化学型的构效关系 (SAR) 时,发现几种其他化合物是具有良好药物样特性的高选择性和强效 AAK1 抑制剂。其中,化合物43和58在两种神经性疼痛大鼠模型中显示出非常好的疗效,并具有出色的中枢神经系统穿透和脊髓靶点接合。这两种化合物还表现出良好的物理化学和口服药代动力学 (PK) 特性。化合物58是 BMS-986176/LX-9211 ( 4 ) 的中心吡啶异构体,在体外比4的效力高 4倍,并且与 CCI 大鼠模型中的4相比,显示出实现相似功效所需的较低血浆暴露。然而,与4相比, 43和58的临床前毒性特征均较差。
