A series of pyridine derivatives of thiazolidin-4-ones (4a-4o) has been synthesized. Structures of these compounds were established on the basis of elemental analysis, IR, 1H NMR, 13C NMR, and Mass spectral data. All the synthesized compounds have been evaluated for their anti-inflammatory and analgesic effects. The results showed that compound 2-[4-methylphenylimino]-5-(1H-pyridin-2-ylmethylidene)-1,3-thiazolidin-4-one (4d), 2-(2,4-dinitro-phenylhydrazinylidine)-5-(1H-pyridin-2-yl-methylidene)-1,3- thiazolidin-4-one (4h), and 2-[3-nitro-phenylimino]-5-(1H-pyridin-2-yl- methylidene)-1,3-thiazolidin-4-one (4j) exhibited good anti-inflammatory and analgesic activity. Compound 4h was found to be the most active compound of the series with an interesting dual anti-inflammatory and analgesic activity. Docking simulation was performed to position synthesized compounds into the active site of COX-2. The relationships of energy-based docking score with analgesic and anti-inflammatory activities were also investigated by linear regression method. The QSAR models with R 2 of 0.621 and 0.740 were developed for analgesic and anti-inflammatory activities, respectively.
