Synthesis, anticonvulsant activity, and neuropathic pain-attenuating activity of N-benzyl 2-amino-2-(hetero)aromatic acetamides
摘要:
N-Benzyl 2-acetamido-2-substituted acetamides, where the 2-substituent is a (hetero) aromatic moiety, are potent anticonvulsants. We report the synthesis and whole animal pharmacological evaluation of 16 analogues where the terminal 2-acetyl group was removed to give the corresponding primary amino acid derivatives (PAADs). Conversion to the PAAD structure led to a substantial drop in seizure protection in animal tests, demonstrating the importance of the N-acetyl moiety for anticonvulsant activity. However, several of the PAADs displayed notable pain-attenuating activities in a mouse model. (C) 2012 Elsevier Ltd. All rights reserved.
