Compounds of formula (I):
[wherein: A is a pyrrole ring; R1 is an optionally substituted phenyl or naphthyl group; R2 is an optionally substituted pyridyl or pyrimidinyl group; R3 represents a group of the formula -X-R4, wherein X is a single bond or an alkenylene group, and R4 is an optionally substituted nitrogen-containing heterocyclyl group; selected from the group consisting of 8-azabicyclo[3.2.1]octenyl, 9-azabicyclo[3.3.1]nonenyl and quinuclidinenyl groups, PROVIDED THAT said substituents R1 and R3 are bonded to the two atoms of said pyrrole ring which are adjacent to the atom of the pyrrole ring to which said substituent R2 is bonded] have excellent inhibitory activity against the production of inflammatory cytokines.

[Object]
The object of the present invention is to provide a composition for the prophylaxis or treatment of hepatopathy.
[Solution]
A composition containing as an active ingredient a compound of formula (I), or a pharmacologically acceptable salt, ester or other derivative thereof for the prophylaxis or treatment of hepatopathy:
[wherein: A is a pyrrole ring; R1 is an optionally substituted aryl or heteroaryl group; R2 is an optionally substituted heteroaryl group; R3 represents a group of the formula -X-R4, wherein X is a single bond or an optionally substituted alkylene, alkenylene or alkynylene group, and R4 is a substituted cycloalkyl group, a substituted aryl group, an optionally substituted heterocyclyl group, an optionally substituted heteroaryl group, or -NRaRb, wherein each of Ra and Rb is a hydrogen atom or an alkyl, alkenyl, alkynyl, aralkyl or alkylsulfonyl group; PROVIDED THAT said substituents R1 and R3 are bonded to the two atoms of said pyrrole ring which are adjacent to the atom of the pyrrole ring to which said substituent R2 is bonded].
We investigated proinflammatory cytokine TNF alpha production inhibitors in order to develop novel anti-inflammatory agents. According to the results, we found that 17, a pyrrole derivative possessing a tetrahydropyridine group at the beta-position, showed potent inhibitory activity in vitro (inhibition of lipopolysaccharide (LPS) induced TNF alpha production in human whole blood, IC(50) = 1.86 mu M) and in vivo (inhibition of LPS induced TNF alpha production in mice, ID(50) = 5.98 mg/kg).
