Abstract

Herein we report the synthesis and evaluation of 14 novel peptides as potential irreversible inactivators of guinea pig liver transglutaminase (TGase). These peptides were designed to resemble Cbz-l-Gln-Gly, known to be a good TGase substrate, and to include a 1, 2, 4- thiadiazole group. The side chain length of the amino acid residue bearing the inhibitor group was also varied in order to permit investigation of this effect. Their inactivation rate ...
