In Silico, In Vitro, and In Vivo Antinociceptive Potential of S‐Naproxen Derivatives
ChemistryOpen, Volume 15, Issue 4, April 2026.Selected naproxen derivatives were investigated for their antinociceptive effects, using in vitro (COX‐I/COX‐II antagonistic effect), in vivo (acetic acid and hot plate assay), and in silico (molecular simulation studies) approaches. The COX inhibition studies revealed that the maximum percent effect exhibited by GMO‐I‐111a 96.01 and 92% against COX‐2 ...
