New Hybrid Molecules Based on Sulfur - Containing Nicotinonitriles: Synthesis, Analgesic Activity in Acetic Acid - Induced Writhing Test, and Molecular Docking Studies

— New hybrid molecules bearing furyl and 1,4-dihydronicotinonitrile (or 1,4,5,6-tetrahydronicotinonitrile) fragments have been prepared. The analgesic activity was studied in vivo (rats) in acetic acid-induced writhing test. Some compounds showed activity exceeding that of the reference compound (metamizole). Molecular docking was performed with all the compounds against COX-1 and COX-2. Also, we performed the docking studies in order to find new possible protein targets.
