A novel compound represented by the formula (I):
wherein rings A and B each represents an optionally substituted aromatic ring, or rings A and B may be bonded to each other through linking between bonds or substituents thereof to form a ring; ring C represents a nitrogenous saturated heterocycle optionally having one or more substituents besides the oxo (provided that 2,3-dioxopyrrolidine ring is excluded); R1 represents hydrogen, an optionally substituted hydrocarbon group, or an optionally substituted heterocyclic group; and
--------¯
indicates a single bond or a double bond. It has high antagonistic activity against a tachykinin receptor, especially an SP receptor.
一种由式(I)代表的新型化合物:
其中,环 A 和环 B 各自代表一个任选取代的芳香环,或环 A 和环 B 可通过其键或取代基之间的连接而相互键合,形成一个环;环 C 代表一个含氮饱和杂环,除了氧代外,还可任选具有一个或多个取代基(前提是不包括 2,3-二氧代吡咯烷环);R1 代表氢、任选取代的烃基或任选取代的杂环基;以及
--------¯
表示单键或双键。它对速激肽受体,尤其是 SP 受体具有很高的拮抗活性。
