Aminocycloalkane compounds represented by the following general formula:
wherein Ar represents a phenyl group or thienyl group with an optional substituent on the ring, X represents a cyano group or carbamoyl group, R1 and R2 are each independent, R1 representing a hydrogen atom or lower alkyl group and R2 representing a hydrogen atom, lower alkyl group, an -A-B group (where A represents a lower alkylene group that is optionally branched and B represents a phenyl group, pyridyl group, thiazole group, imidazole group, furyl group or pyrrolidinyl group with an optional substituent on the ring) or an alkenyl group, or R1 and R2 together with the nitrogen atom to which they are bonded represent
(where R3 represents a hydrogen atom, a lower alkyl group that is optionally substituted with a phenyl group, or an alkenyl group), and m represents 2, 3 or 4, and pharmacologically acceptable salts thereof.
The compounds have highly selective antagonistic activity for muscarinic M3 receptor subtypes, and are therefore useful as preventive or therapeutic agents for diseases related to muscarinic M3 receptor subtypes.
由以下通式表示的氨基环烷烃化合物:
其中 Ar 代表苯基或噻吩基,环上有任选的取代基,X 代表氰基或氨基甲酰基,R1 和 R2 各自独立,R1 代表氢原子或低级烷基,R2 代表氢原子、低级烷基、-A-B基团(其中 A 代表可选支链的低级亚烷基,B 代表苯基、吡啶基、噻唑基、咪唑基、呋喃基或吡咯烷基,环上可选取代基)或烯基,或 R1 和 R2 与它们键合的氮原子一起代表
(其中 R3 代表氢原子、任选被苯基取代的低级烷基或烯基),m 代表 2、3 或 4,及其药理学上可接受的盐。
这些化合物对毒蕈碱 M3 受体亚型具有高度选择性拮抗活性,因此可作为预防或治疗与毒蕈碱 M3 受体亚型相关疾病的药物。
