A bicyclic unsaturated tertiary amine compound capable of inhibiting the production of inflammatory cytokines. The compound has the following formula (I):
wherein A represents pyrrole or pyrazole, R
1
represents an aryl group or a heteroaryl group which may be substituted, R
2
represents a heteroaryl group which may be substituted, and R
3
represents an indolizine group, or a pharmacologically acceptable salt thereof, a pharmacologically acceptable ester thereof or a pharmacologically acceptable derivative thereof.
Compounds of the formula (I) below, or pharmacologically acceptable salts, esters or other derivatives thereof:
1
wherein A is furan, thiophene, pyrazole, imidazole, isoxazole or isothiazole;
R
1
is a substituted or unsubstituted aryl or a substituted or unsubstituted heteroaryl; R
2
is a substituted or unsubstituted heteroaryl; and R
3
is a bicyclic amino group; provided that the substituents R
1
and R
2
are bonded to the two atoms of the cyclic group A which are adjacent to the atom of the cyclic group A to which the substituent R
2
is bonded. The compounds inhibit the production of inflammatory cytokines.
The present invention provides a bicyclic unsaturated tertiary amine compound capable of inhibiting the production of inflammatory cytokines.
A compound of the following formula (1):
(wherein,
A represents pyrrole or pyrazole, R1 represents an aryl group or a heteroaryl group which may be substituted, R2 represents a heteroaryl group which may be substituted, and R3 represents an indolizine group), or a pharmacologically acceptable salt thereof, a pharmacologically acceptable ester thereof or other pharmacologically acceptable derivative thereof.
