Abstract
本发明提供了一种稠合三环衍生物的制备方法及中间体。所述稠合三环衍生物具有式(I)所示的结构。所述制备方法原料易得、步骤简单,适宜大规模工业化生产。
Description
本发明涉及医药领域,具体的说,本发明涉及一种稠合三环衍生物的制备方法及中间体。
电压门控钙通道由α1亚单位和辅助蛋白α2δ、β、γ亚基共同构成。α2δ蛋白可以调节钙通道的密度及钙通道电压依赖性动力学(Felix et al(199 7)J.Neuroscience 17:6884-6891;Klugbauer et al(1999)J.Neuroscience 19:684-691;Hobom et al(2000)Eur.J.Neuroscience 12:1217-1226;and Qin et al(2002)Mol.Pharmacol.62:485-496)。已经证实,对电压依赖性钙通道亚基α2δ表现出高亲合力结合的化合物可有效治疗疼痛,例如普瑞巴林和加巴喷丁。在哺乳动物中,α2δ蛋白有4个亚型,每个亚型均由不同的基因编码。α2δ亚型1和亚型2与普瑞巴林表现出高亲和力,而α2δ亚型3和亚型4无显著的药物结合力。
然而,对于加巴喷丁,其较大程度改善糖尿病周围神经病变患者病痛的比例约为60%(Acta Neurol.Scand.101:359-371,2000),对于普瑞巴林,虽然其耐受性优于加巴喷丁,但其安全性更低,且有滥用或者使患者产生依赖的可能(Am J Health Syst Pharm.2007;64(14):1475-1482)。
开发新的对电压依赖性钙通道亚基α2δ表现出高亲合力结合的化合物仍然有很大的需求。
PCT/CN2017/101364专利申请公开了一种稠合三环γ-氨基酸衍生物及其制备方法和在医药上的应用,它们具有良好的生物活性,同时也公开了制备该衍生物的中间体式(I)化合物及其制备方法,
