Abstract
Site-selective chemical protein modification has emerged as a powerful strategy to install biophysical probes and post-translational modifications as well as for the conjugation of therapeutic payloads at pre-determined sites. A number of methodologies based on reactions that address biocompatibility, reactivity and (chemo)selectivity issues have been developed. Here we present selected examples of site-selective protein modification protocols including (a) the preparation of fluoroglycoproteins and (b) the development of Se-based bioconjugation methods as well as recent advances exploring small handles for (c) the chemoselective installation of secondary amine linkages on proteins via formation of C–N bonds at dehydroalanine-tagged proteins, (d) inverse electron demand Diels-Alder reactions (IEDDA), and (e) Ru(II)-hydrosilylation, among others.
