专利名称:含氮杂环化合物的制作方法技术领域:本发明涉及具有优异药物活性的含氮杂环化合物。心绞痛是一种常常危害老年人的局部缺血心脏病。尽管有用硝酸化合物和亚硝酸化合物,钙拮抗药和β-阻滞剂作为治疗上述疾病的药物,但上述治疗药物对心绞痛的治疗效果远远不足,或不足以阻止所述疾病发展成冠状动脉梗塞。近来,患有心绞痛的患者年龄下降,并且由于生活方式的改变,社会压力逐渐增加等,该疾病的症状也变得复杂起来。因此急需一种新的活性更优异的药物。环状GMT(以下简称cGMT)是一种环状核苷酸,作为一种细胞内第二信使参与上述药物中的硝酸和亚硝酸化合物的作用。cGMT对脉管和支气管中的平滑肌的作用是已知的。尽管上述药物的作用机理还不清楚,但一般认为,所述药物活化了乌苷酸环化酶,从而加速了cGMT的合成。但是,上述药物的生物可利用性低而且作用时间比较短。此外据报导还可产生药物抵抗作用,这在临床中是一缺陷。在这种情况下,本发明人开始研究一种新的具有优异活性的药物。多年来,本发明人着力研究具有活性的cGMT-磷酸二酯酶(以下简称“cGMT-PDE”)。研究结果发现,下述含氮杂环化合物对各种局部缺血心脏病具有有效活性,从而完成了本发明。日本专利公开502462(1990)公开了一种作为药物的喹唑啉衍生物,但其在结构和活性方面与本发明化合物不同。本发明提供了一种式(1)所示的含氮杂环化合物或其药用盐
