Constrained analogues of tocainide as potent skeletal muscle sodium channel blockers towards the development of antimyotonic agents
摘要:
1-Benzyl-N-(2,6-dimethylphenyl)piperidine-3-carboxamide and 4-benzyl-N-(2,6-dimethylphenyl)piperazine-2-carboxamide, two conformationally restricted analogues of tocainide, were designed and synthesized as voltage-gated skeletal muscle sodium channel blockers. They showed, with respect to tocainide, a marked increase in both potency and use-dependent block. (C) 2008 Published by Elsevier Masson SAS.
