The discovery of a novel series of NR2B subtype selective N-methyl-d-aspartate (NMDA) antagonists is reported. Initial optimization of a high-throughput screening lead afforded an aminopyridine derivative 13 with significant NR2B antagonist potency but limited selectivity over hERG-channel and other off-target activities. Further structure-activity studies on the aminoheterocycle moiety and optimization
据报道发现了一系列新的NR2B亚型选择性N-甲基-d-天冬氨酸(NMDA)拮抗剂。高通量筛选前导物的初步优化提供了具有显着NR2B拮抗剂效力但对hERG通道和其他脱靶活性的选择性有限的氨基吡啶衍生物13。对氨基杂环部分的进一步结构活性研究和氨基甲酸酯的优化导致了高效的2-氨基嘧啶衍生物20j,其在多个物种中的脱靶活性谱和口服生物利用度显着提高,并具有良好的脑渗透性。化合物20j在抗伤害感受,异常性疼痛和帕金森氏病的体内啮齿动物模型中显示出功效。
