摘要
Linear and cyclic olefin peptides containing the substrate sequence for human T-cell leukemia virus type-1 (HTLV-1) were efficiently synthesized on a solid support using the Horner-Emmons reaction. The precursor peptide aldehyde was prepared by oxidation of the corresponding peptide alcohol with Dess-Martin periodinane. The oxidation reaction proceeded quantitatively on a cross-linked ethoxylate acrylate resin (CLEAR) support instead of a polystyrene-based support. Cyclization on the solid support was achieved via an amide bond formation mediated by EDC/HOAt to yield a single major product. The linear olefin peptide was cleaved by HTLV-1 protease at the scissile site, whereas the cyclic olefin peptide functions as a competitive inhibitor rather than a substrate. (C) 2003 Elsevier Ltd.
