    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.
