Design, synthesis, and anticonvulsant effects evaluation of nonimidazole histamine H₃ receptor antagonists/inverse agonists containing triazole moiety.

ABSTRACT: Histamine H₃ receptors (H₃R) antagonists/inverse agonists are becoming a promising therapeutic approach for epilepsy. In this article, novel nonimidazole H₃R antagonists/inverse agonists have been designed and synthesised via hybriding the H₃R pharmacophore (aliphatic amine with propyloxy chain) with the 1,2,4-triazole moiety as anticonvulsant drugs. The majority of antagonists/inverse agonists prepared here exerted moderate to robust activities in cAMP-response element (CRE) luciferase screening assay. 1-(3-(4-(3-Phenyl-4H-1,2,4-triazol-4-yl)phenoxy)propyl)piperidine (3l) and 1-(3-(4-(3-(4-chlorophenyl)-4H-1,2,4-triazol-4-yl)phenoxy)propyl)piperidine (3m) displayed the highest H₃R antagonistic activi
