Hydrazone- and hydrazide-containing N-substituted glycines as peptoid surrogates for expedited library synthesis: applications to the preparation of Tsg101-directed HIV-1 budding antagonists

[Image: see text] Replacing the Pro6 in the p6(Gag)-derived 9-mer “P-E-P-T-A-P-P-E-E” with N-substituted glycine (NSG) residues is problematic. However, incorporation of hydrazone amides (“peptoid hydrazones”) can be readily achieved in library fashion. Furthormore, reduction of these hydrazones to N-substituted “peptoid hydrazides” affords a facile route to library diversification. This approach is demonstrated by application to Tsg101-binding compounds designed as potential HIV budding antagonists
