Structure–Activity Study and Analgesic Efficacy of Amino Acid Derivatives as N-Type Calcium Channel Blockers
摘要:
The synthesis and structure activity relationship (SAR) study of a novel series of N-type calcium channel blockers are described. L-Cysteine derivative 2a was found to be a potent and selective N-type calcium channel blocker with IC50 0.63 muM on IMR-32 assay. Compound 2a showed analgesic efficacy in the rat formalin-induced pain model by intrathecal and oral administration. (C) 2001 Elsevier Science Ltd. All rights reserved.
