Within the series of chiral 3,3'-(1,2-ethanediyl)bis[2-arylthiazolidin-4-ones], the 3,4-dimethoxyphenyl substituted derivative was found in the primary anti-inflammatory screening to be endowed with superior in vivo properties and good safety profile. Such a lead compound was modified by eliminating 3-methoxy group while retaining 4-methoxy group on the aryl rings at 2 and 2' stereogenic carbons. The 2R,2'S-meso isomer (VIG3b) of the resulting bisthiazolidinone has been widely investigated. The inhibitory effects on cyclo-oxygenase-1 and cyclo-oxygenase-2 isoenzymes were measured in a human whole blood assay. VIG3b was almost 50 times more selective on the inducible isoform. The cyclo-oxygenase-2 preferential selectivity has been confirmed by modeling VIG3b into the cyclo-oxygenase-1 and cyclo-oxygenase-2 active sites. furthermore, VIG3b was assayed in the experimental model of carrageenan-induced lung injury by evaluating its ability to inhibit: (1) fluid accumulation in the pleural cavity, (2) neutrophil infiltration, (3) prostaglandin E-2 production and (4) lung injury. VIG3b exhibited interesting activity in all these tests. (C) 2002 Elsevier Science B.V. All rights reserved.
Synthesis and antiinflammatory, analgesic activity of 3,3′-(1,2-Ethanediyl)-bis[2-aryl-4-thiazolidinone] chiral compounds. Part 10
In this note, the synthesis and structure-activity relationships of a new series of 2R,2'R/2S,2'S and 2R,2'S-meso 3,3'-(1,2-ethanediyl)-bis[2-aryl-4-thiazolidinones] are described. Antiinflammatory activity was investigated by the carrageenin-induced paw edema test and analgesic activity by aceticacid writhing and hot plate tests in rats. All compounds displayed ulcerogenic effects and acute toxicity
