Synthesis and anticonvulsant activity of aromatic tetramethylcyclopropanecarboxamide derivatives
摘要:
As part of our ongoing research on potential new antiepileptic drugs (AEDs), a series of tetramethylcyclopropanecarboxamide derivatives containing benzene ring were designed, synthesized, and evaluated for anticonvulsant activities in the murine maximal electroshock (MES) and subcutaneous pentylenetetrazole (scMet) seizure tests. The most potent compound emerging from this study was N-(2,2,3,3-tetramethylcyclopropanecarboxamide)-p-phenyl-sulfonamide (21), possessing an ED50 value of 26 mg/kg in the rat-MES test and a remarkable PI (PI = TD50/ED50) value above 19. The better anticonvulsant potency of compound 21 and its wider safety margin compared to valproic acid (VPA) and zonisamide make it a potential candidate to become a new AED second-generation to VPA.
