modification of heparin is shown to afford charge-reduced heparin derivatives that possess increased selectivity for binding heparin-binding proteins. Variable N-desulfonation of heparin was employed to afford heparin fractions possessing varied levels of free amine. These N-desulfonated heparin fractions were selectivelyN-acylated with structurally diverse carboxylic acids using a parallel synthesis

Using a tetrapeptide-based alpha-ketoamide template, various amines and amino acids were incorporated to explore the prime side of the HCV NS3 protease catalytic site. Glycine carboxylic acid was found to be the most effective prime group. Further optimization yielded an inhibitor with IC50 of 0.060 muM. (C) 2003 Elsevier Science Ltd. All rights reserved.
