چکیده انگلیسی
We describe novel peptide-based caspase inhibitors. Potent and comparatively selective compounds containing a dipeptide scaffold and a substituted oxymethyl ketone as a warhead were developed. The newly synthesized compounds were tested for inhibition in in vitro enzymatic assays of caspases-1, -3, -6, -8, and -9. The benzyloxycarbonyl-phenylglycyl-aspartyl benzoyloxymethyl ketone (Z-Phg-Asp-CH2OCO-Ph, coded as HU44) was the most potent inhibitor of caspase-1 and caspase-3. Of several analogs of HU44 that were made, the β-Asp methyl ester (2) is an effective inhibitor against caspase-3 and caspase-8, and less effective against caspase-1. These compounds did not inhibit caspase-6 and caspase-9 significantly.
