    • 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-methyl-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)的化合物及其药学上可接受的盐:其中Y是C 2 -C 4亚烷基; Z是价键或C1-C6亚烷基; R 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); R2是氢或C1-C6烷基; R3是氢,羟基等; R4是取代或未取代的苄基等。 典型实例是(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的氮杂环羧酸具有优异的物质P拮抗活性,因此可用于治疗哺乳动物,特别是人类的胃肠疾病,中枢神经系统疾病,变态反应,炎性疾病,哮喘,疼痛,呕吐或偏头痛。
