摘要:
Compounds of formula (I) wherein R1 is hydrogen or halogen; R2 is electron withdrawing group; R3 is hydrogen, hydroxy, lower alkoxy, cycloalkyl, substituted or unsubstituted aryl or substituted or unsubstituted, unsaturated heterocycle; A is lower alkylene; R4 is lower alkoxy, substituted or unsubstituted, saturated or unsaturated heterocycle, substituted or unsubstituted amino, -CH¿2?-R?5, -CR6R7R8¿ wherein R?6 and R7¿ are each independently carboxy, protected carboxy, substituted or unsubstituted carbamoyl, or substituted or unsubstituted lower alkyl, or R?6 and R7¿ together with the carbon atom to which they are attached may form substituted or unsubstituted, saturated carbocycle, or substituted or unsubstituted, unsaturated carbocycle, and R8 is hydrogen, lower alkoxy, or substituted or unsubstituted lower alkyl; provided that when R?4 is -CR6R7R8¿ wherein R?6 and R7¿ are each independently substituted or unsubstituted lower alkyl, and R8 is hydrogen or lower alkyl, or when R4 is -CH¿2?-R?5, R3¿ should be hydrogen, hydroxy or cycloalkyl.
摘要:
Compounds of formula (Ia) wherein Xa is CH or nitrogen, Ya is oxygen or sulfur, R?1a and R2a¿ are specific substituents, R?3a, R4a and R5a¿ are the same or different, hydrogen, halogen, cyano, lower alkoxy or lower-alkoxy-substituted aralkyl; or two of R?3a, R4a and R5a¿ may combine together to form lower alkylenedioxy, and m is 1 or 2, are useful as cGMP-PDE inhibitors.
wherein R 1 is alkyl, alkenyl, alkynyl and the like; A is an optionally substituted heteropolycyclic group except benzimidazolyl, indolyl, 4,7-dihydrobenzimidazolyl and 2,3-dihydrobenzoxazinyl; X is alkylene, oxa, oxa(lower)alkylene and the like; and R 2 is optionally substituted aryl, substituted biphenylyl and the like, a salt thereof and a pharmaceutical composition comprising the same. The sulfonamide compound is effective for the diseases treatable based on their blood sugar level-depressing activity, cGMP-PDE (especially PDE-V)-inhibiting activity, smooth muscle relaxing activity, bronchodilating activity, vasodilating activity, smooth muscle cell suppressing activity, and antiallergic activity.
