Inhibitors of OGT (O-GlcNActransferase) are valuable tools to study the cell biology of protein O-GlcNAcylation. We report OGT bisubstrate-linked inhibitors (goblins) in which the acceptor serine in the peptide VTPVSTA is covalently linked to UDP, eliminating the GlcNAc pyranoside ring. Goblin1 co-crystallizes with OGT, revealing an ordered C₃ linker and retained substrate-binding modes, and binds

suitable for peptide synthesis, development of a protective group strategy for peptide fragments compatible with the integrity of the adenosine diphosphate moiety, and an efficient procedure for pyrophosphate formation. In this paper we present a first approach to the chemicalsynthesis of ADP-ribosylated peptides in solution and on solidsupport. We describe an efficient synthesis of suitably protected

high yields, which also allowed a chemoselective lipidation of an unprotected azido polypeptide. Finally, monolipidated phosphoramidate peptides obtained by the unsymmetrical Staudinger phosphite reaction led to the formation of micelle-like structures and cellular uptake.

A one-potprocedure for the preparation of phosphoramidates, phosphorothioates, pyrophosphates, phosphodiesters, and phosphofluoridates has been devised using di(p-methoxybenzyl)-N,N-diisopropylphosphoramidite as the common phosphitylating reagent.
