Synthesis and evaluation of peptidic maleimides as transglutaminase inhibitors
摘要:
A series of novel transglutaminase inhibitors was prepared, based on the scaffold of a commonly used peptide substrate and bearing an electrophilic maleimide group. These compounds were evaluated in vitro and shown to lead to irreversible inactivation of tissue transglutaminase. Comparison with inhibitors studied previously provides insight into the steric environment of the enzyme active site. (c) 2006 Elsevier Ltd. All rights reserved.

A concise, general, and high-yielding method for the preparation of N(G)-aminoguanidines fromprimaryamines is reported. Using available and readily prepared materials, primaryamines are converted to protected N(G)-aminoguanidines in a one-pot procedure. The method has been successfully applied to a number of examples including the syntheses of four nitric oxide synthase (NOS) inhibitors. The inhibitors
