CRYSTAL STRUCTURE OF CASPASE-8 IN COMPLEX WITH AZA-PEPTIDE MICHAEL ACCEPTOR INHIBITOR

Overview

Aza-peptide Michael acceptors are a novel class of inhibitors that are, potent and specific for caspases-2, -3, -6, -7, -8, -9, and -10. The, second-order rate constants are in the order of 10(6) M(-1) s(-1). The, aza-peptide Michael acceptor inhibitor 18t, (Cbz-Asp-Glu-Val-AAsp-trans-CH=CH-CON(CH(2)-1-Naphth)(2) is the most, potent compound and it inhibits caspase-3 with a k(2) value of 5620000, M(-1) s(-1). The inhibitor 18t is 13700, 190, 6.4, 594, 37500, and, 173-fold more selective for caspase-3 over caspases-2, -6, -7, -8, -9, and, -10, respectively. Aza-peptide Michael acceptors designed with caspase, specific sequences are selective and do not show any cross reactivity with, clan CA cysteine proteases such as papain, cathepsin B, and calpains., High-resolution crystal structures ...
