1. A cyclic compound of the formula (I) or a pharmacologically acceptable salt thereof,
1
wherein X is ═CH— or ═N—, Y is —NH—, —NR
4
—, —S—, —O—, —CH═N—, —N═CH—, —N═N—, —CH═CH—, etc., R
1
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), R
2
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), R
3
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 R
3
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.
化合物的公式(I)或其药理学上可接受的盐,其中X为═CH—或═N—,Y为—NH—,—NR4—,—S—,—O—,—CH═N—,—N═CH—,—N═N—,—CH═CH—等,R1为较低的烷氧基,氨基,含N原子的杂环环,或者由含N原子的杂环环取代的羟基(每个都可以取代),R2为较低的烷基氨基基,可以由芳基取代,较低的烷氧基,可以由芳基取代,由含N原子的芳基取代的较低的烷氧基,R3为芳基,含N原子的杂环环,较低的烷基,较低的烷氧基,环状较低的烷氧基,由含N原子的杂环环取代的羟基,或者氨基(每个都可以取代),R3和Y中的取代基可以结合形成内酯环。本发明的化合物具有优异的选择性PDE V抑制活性,因此,可用作治疗或预防因cGMP信号传导功能障碍引起的各种疾病的药物。
