摘要:
This article describes the synthesis and biological evaluation of a series of dipeptidyl aspartyl fluoromethylketones as caspase-3 inhibitors. Structure-activity relationship (SAR) studies showed that for caspase-3 inhibition, Val is the best P-2 amino acid. The SAR studies also showed that the Asp free carboxylic acid in P-1 is important for caspase inhibiting activities, as well as for selectivity over other proteases. (C) 2003 Elsevier Ltd.
