Solid-phase total synthesis of the chitinase inhibitor argadin using a supported acetal resin

Abstract

A versatile solid-phase total synthesis was applied to the rapid preparation of Argadin, a natural product isolated and characterized as a cyclopentapeptide by our group, which possesses superior inhibitory activity against family-18 chitinases. The synthetic strategy includes peptide synthesis by using an Fmoc (9-fluorenylmethoxycarbonyl) protective group, macrolactamization, acetylguanylation and formation of hemiaminal accompanied by total deprotection, including cleavage from resin. © 2009 Japan Antibiotics Research Association All rights reserved.
