Zusammenfassung:A pyrazoloquinoline derivative having the formula (I): wherein R , R , and R independently represent a hydrogen atom or a lower alkyl group; R 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 R 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.
