Tetrahydropyridine derivatives with inhibitory activity on the production of proinflammatory cytokines: Part 3

In order to develop a new class of anti-rheumatic drug which inhibits production of proinflammatory cytokines such as TNFα, IL-1β, IL-6, and IL-8, a series of 3-pyridylpyrrole derivatives possessing a bicyclic tetrahydropyridine moiety at the 4-position o

Heteroaryl-substituted pyrrole derivatives, their preparation and their therapeutic uses

Compounds having activity against production of an inflammatory cytokine of formula (I)′: 1A′ is pyrrole; R1′ is phenyl or naphthyl; R2′ is pyridyl or pyrimidinyl; R3′ is (IIa)′, (IIb)′ or (IIc)′: 2m′ is 1; E′ is nitrogen; D′ is >C(R5′)—, R5′ is hydrogen, Substituent α′ or Substituent β′; B′ is nitrogen-containing 5-membered heterocyclic; R4′ is 1 to 3 substituents from Substituent α′, Substituent β′ and Substituent γ′; R1′ and R3′ are bonded to two atoms of the pyrrole adjacent to the pyrrole atom bonded to R2′; Substituent α′ is hydroxyl, nitro, cyano, halogen, alkoxy, halogeno alkoxy, alkylthio, halogeno alkylthio or —NRa′Rb′; Ra′ and Rb′ are hydrogen, alkyl, alkenyl, alkynyl, aralkyl or alkylsulfonyl, or Ra′ and Rb′ with the nitrogen atom form a heterocyclyl; Substituent β′ is alkyl, alkenyl, alkynyl, aralkyl or cycloalkyl; Substituent γ′ is oxo, hydroxyimino, alkoxyimino, alkylene, alkylenedioxy, alkylsulfinyl, alkylsulfonyl, aryl, aryloxy, alkylidenyl or aralkylidenyl.

Heteroaryl-substituted pyrrole derivates, their preparation and their therapeutic uses

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.
