Cyclooxygenase-1/2 (COX-1/COX-2) and 5-lipoxygenase (5-LOX) inhibitors of the 6,7-diaryl-2,3-1H-dihydropyrrolizine type
摘要:
A series of 6,7-diaryl-2,3-1H-dihydropyrrolizines was prepared as COX-1/COX-2 and 5-LOX inhibitors. The inhibition of COX-1 was evaluated using intact bovine platelets as the enzyme source, whereas LPS-stimulated human monocytes served as the enzyme source for inducible COX-2. The determination of arachidonic metabolites was performed by HPLC for COX-1 and RIA for COX-2. The balance between COX-1/COX-2 and 5-LOX inhibition can be shifted by modifying the substitution pattern of the phenyl moiety at the 6- and 7-position of the pyrrolizine nucleus. Structure-activity relationships are discussed. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.

The present invention relates to fused pyrrole compounds of the formula 1.
1
in which at least one of the radicals R1, R2, R3 is 4-sulphur-substituted phenyl.
These compounds are in particular pyrrolizines, indolizines and heteroanalogues having selective inhibitory action on isoenzyme-2 of prostaglandin H synthase (COX-2). The invention also relates to pharmaceutical compositions which contain these compounds; and the use of these compounds for the treatment of disorders of the rheumatic type.
