A compound of the chemical formula (I) and its pharmaceutically acceptable salt: ##STR1## wherein Y is C.sub.2 -C.sub.4 alkylene; Z is a valence bond or C.sub.1 -C.sub.6 alkylene; R.sup.1 is substituted or unsubstituted aryl (e.g., phenyl and naphthyl) or heteroaryl (e.g., thienyl and furyl); R.sup.2 is hydrogen or C.sub.1 -C.sub.6 alkyl; R.sup.3 is hydrogen, hydroxy or the like; R.sup.4 is substituted or unsubstituted benzyl or the like. Typical examples are (2S*,3S*,4R*,5R*)-4-Carboxy-3-[N-(5-Isopropyl-2-methoxy-benzyl)amino]-5-me thyl-2-phenylpyrrolidine and (2S*,3S*,5S*)-5-Carboxy-3-[N-(2-methoxy-5-trifluoromethoxybenzyl)amino]-2- phenylpiperidine. The novel substituted azaheterocyclecarboxylic acids in this invention have excellent substance P antagonistic activity and are thus useful for the treatment of gastrointestinal disorders, central nervous system disorders, allergy, inflammatory diseases, asthma, pain, emesis or migraine in mammals, especially humans.
化学式(I)的化合物及其可药用的盐:##STR1## 其中Y是C.sub.2 -C.sub.4亚烷基;Z是价键或C.sub.1 -C.sub.6亚烷基;R.sup.1是取代或未取代的芳基(例如,苯基和萘基)或杂芳基(例如,噻吩基和呋喃基);R.sup.2是氢或C.sub.1 -C.sub.6烷基;R.sup.3是氢、羟基或类似物;R.sup.4是取代或未取代的苄基或类似物。典型的例子是(2S*,3S*,4R*,5R*)-4-羧基-3-[N-(5-异丙基-2-甲氧基苄基)氨基]-5-甲基-2-苯基吡咯烷和(2S*,3S*,5S*)-5-羧基-3-[N-(2-甲氧基-5-三氟甲氧基苄基)氨基]-2-苯基哌啶。本发明中的新型取代氮杂环羧酸具有优异的P物质拮抗活性,因此可用于治疗哺乳动物的胃肠道疾病、中枢神经系统疾病、过敏、炎症性疾病、哮喘、疼痛、呕吐或偏头痛,尤其是人类。
