摘要: A pyrazoloquinoline derivative having the formula (I):
wherein R¹, R², and R³ independently represent a hydrogen atom or a lower alkyl group; R⁴ represents a hydrogen atom, a lower alkyl group, a halogen-substituted lower alkyl group, or a lower alkoxycarbonyl group; the dotted line means that the pyrazole ring has two conjugated double bonds; and R⁴ is bonded to the nitrogen atom at the 1-position or 2-position, or pharmacologically acceptable salts thereof. These compounds exhibit excellent anti-inflammatory activity and hepatic insufficiency treating activity.摘要翻译: 具有式(I)的吡唑并喹啉衍生物:其中R 1,R 2和R 3独立地代表氢原子或低级烷基; R 4代表氢原子,低级烷基,卤素取代的低级烷基或低级烷氧基羰基; 虚线表示吡唑环具有两个共轭双键; 并且R 4与1-位或2-位的氮原子键合,或其药理学上可接受的盐。 这些化合物表现出优异的抗炎活性和肝功能不全治疗活性。

摘要: Disclosed are naphthyridine derivatives represented by formula (I)
wherein:
X represents hydrogen; lower alkyl; aralkyl; substituted or unsubstituted aryl; substituted or unsubstituted aromatic heterocyclic group; -NR¹R² wherein R¹ and R² independently represent hydrogen or lower alkyl;
wherein W represents N or CH, Z represents a single bond, oxygen or NR³ (wherein R³ represents hydrogen, lower alkyl or benzyl) and n1 and n2 represent an integer of 1 to 3; or substituted or unsubstituted thiazolinyl; and
Y is a single bond or alkylene
and pharmaceutically acceptable salts thereof. The compounds show potent anti-inflammatory activity and are expected to be useful in treating rheumarthritis.摘要翻译: 公开了由式(I)表示的萘啶衍生物
