The target is to provide PDE IV inhibitors which have a highly potent anti-asthmatic and/or COPD-prophylactic/therapeutic profile with unexpectedly excellent safety. A compound of the formula (1):
wherein A is phenyl, pyridyl, 1-oxypyridyl, or thienyl, which may be unsubstituted or optionally substituted with one or more members selected from the group consisting of hydroxyl, halogen, cyano, nitro, lower alkyl, lower alkoxy, lower alkylcarbonyloxy, amino, carboxyl, lower alkoxycarbonyl, carboxy-lower alkylene, lower alkoxycarbonyl-lower alkylene, lower alkylsulfonyl, lower alkylsulfonylamino, and ureido; R
1
is a group selected from the group consisting of hydrogen, hydroxyl, halogen, cyano, nitro, lower alkoxy, amino, carboxyl, and lower alkoxycarbonyl; R
2
is hydrogen or lower alkyl; and m is an integer of 1 to 3; or a pharmaceutically acceptable salt thereof, possesses highly excellent PDE IV-specific inhibitory actions and is useful as an anti-asthmatic drug and/or a prophylactic/therapeutic drug for COPD with high safety.
目标是提供高度有效的PDE IV抑制剂,具有极强的抗哮喘和/或COPD预防/治疗特性,同时具有意外的优异安全性。公式(1)的化合物:其中A为苯基,吡啶基,1-氧代吡啶基或噻吩基,可以是未取代或可选地取代为羟基,卤素,氰基,硝基,低烷基,低烷氧基,低烷基羰氧基,氨基,羧基,低烷氧羰基,羧基-低烷基烯,低烷氧羰基-低烷基烯,低烷基磺酰基,低烷基磺酰胺基和脲基中的一个或多个成员;R1是从氢,羟基,卤素,氰基,硝基,低烷氧基,氨基,羧基和低烷氧羰基中选择的一个基团;R2是氢或低烷基;m是1到3的整数;或其药学上可接受的盐,具有高度优异的PDE IV特异性抑制作用,并可用作高安全性的抗哮喘药物和/或COPD预防/治疗药物。
