We report herein the synthesis of ¾ substituted benzene sulfonamides linked via phenyl ring to a benzothiazole moiety. The title compounds in the two series namely N-(4-(benzothiazole-2-yl) phenyl) 4- substituted benzene sulfonamides and N-(4-(benzothiazole-2-yl) phenyl) 3- substituted benzene sulfonamides were synthesized by condensing 2-(3/4-aminophenyl) benzothiazole with various substituted sulfonyl chlorides. The synthesized compounds were subjected to neurotoxicity screening, computational studies, and evaluation of their anticonvulsant potential. Amongst all the synthesized compounds, compound 9 emerged as the most potent anticonvulsant agent in maximal electroshock (MES) model (standard: phenytoin) in mice and showed three hydrogen bond interactions with the nicotinic acetylcholine ion gated receptors (PDB ID: 2BG9). Interestingly, compound 13 showed five hydrogen bond interactions with the target protein and thus excellent binding affinity upon computational analysis but was found to be neurotoxic.
