1. A cyclic compound of the formula (I) or a pharmacologically acceptable salt thereof,
wherein X is =CH-or=N-, Y is-NH-, -NR4-, -S-, - O-, -CH=N-, -N=CH-, -N=N-, -CH=CH-, etc., R1 is a lower alkoxy group, an amino group, a heterocyclic ring containing N atom(s), or a hydroxy group substituted by a heterocyclic ring containing N atom(s) (each of which is optionally substituted), R2 is a lower alkylamino group which is optionally substituted by an aryl group, a lower alkoxy group which is optionally substituted by an aryl group, a lower alkoxy group substituted by an aromatic heterocyclic ring containing N atom(s), R3 is an aryl group, a heterocyclic ring containing N atom(s), a lower alkyl group, a lower alkoxy group, a cyclo lower alkoxy group, a hydroxy group substituted by a heterocyclic ring containing N atom(s), or an amino group (each of which is optionally substituted), and R3 and a substituent in Y may be combined to form a lactone ring.
The compound of the present invention has excellent selective PDE V inhibitory activity and therefore, is useful as a therapeutic or prophylactic drug for treating various diseases due to functional disorders on cGMP-signaling.
1.式(I)的环状化合物或其药理学上可接受的盐、
其中 X 是 =CH-or=N-, Y 是-NH-、-NR4-、-S-、-O-、-CH=N-、-N=CH-、-N=N-、-CH=CH-等、R1 是低级烷氧基、氨基、含 N 原子的杂环或被含 N 原子的杂环取代的羟基(其中每一个都可选择被取代), R2 是低级烷基氨基,可选择被芳基取代,低级烷氧基,可选择被芳基取代、R3 是芳基、含 N 原子的杂环、低级烷基、低级烷氧基、环低级烷氧基、被含 N 原子的杂环取代的羟基或氨基(其中每个基团都可选择被取代),R3 和 Y 中的一个取代基可结合形成一个内酯环。
本发明的化合物具有优异的选择性 PDE V 抑制活性,因此可用作治疗或预防药物,用于治疗因 cGMP 信号转导功能紊乱而引起的各种疾病。
