The present invention provides a compound represented by the formula:
wherein Ar is an aryl group, an aralkyl group or an aromatic heterocyclic group, each of which may be substituted, R
1
is a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group or an optionally substituted heterocyclic group, X is an oxygen atom or an optionally lo substituted imino group, Z is an optionally substituted methylene group, Ring A is an optionally further substituted piperidine ring, and Ring B is an optionally substituted aromatic ring, provided that when Z is a methylene group substituted with an oxo group, R
1
is not a methyl group, and 15 when Z is a methylene group substituted with a methyl group, Ring B is a substituted aromatic ring, or a salt thereof, which is a novel piperidine derivative having excellent antagonistic action for a tachykinin receptor and useful as a medicament, particularly an agent for preventing and/or treating urinary frequency and/or urinary incontinence.
本发明提供了一种化合物,其表示为以下式子:其中Ar是芳基、芳基烷基或芳香杂环基,每个基团都可以被取代,R1是氢原子、可选取代的碳氢基团、酰基或可选取代的杂环基团,X是氧原子或可选取代的亚胺基团,Z是可选取代的亚甲基团,环A是可选进一步取代的哌啶环,环B是可选取代的芳香环,但当Z是取代有氧基的亚甲基团时,R1不是甲基基团,而当Z是取代有甲基基团的亚甲基团时,环B是取代的芳香环,或其盐。该化合物是一种新型哌啶衍生物,具有优异的缓解速激肽受体拮抗作用,可用作药物,特别是用作预防和/或治疗尿频和/或尿失禁的药剂。
