growing application of tetrazine bioorthogonal chemistry, it is still challenging to access tetrazines conveniently from easily available materials. Described here is the de novo formation of tetrazine from nitriles and hydrazine hydrate using a broad array of thiol‐containing catalysts, including peptides. Using this facile methodology, the syntheses of 14 unsymmetric tetrazines, containing a range of
Site‐selective modification of proteins has been the object of intense studies over the past decades, especially in the therapeutic field. Prominent results have been obtained with recombinant proteins, for which site‐specific conjugation is made possible by the incorporation of particular amino acid residues or peptide sequences. In parallel, methods for the site‐selective and site‐specific conjugation

A hydrogel composition includes: (1) a polymer network including a first water-soluble polymer and a second water-soluble polymer that are crosslinked through dynamic bonds; and (2) a catalyst to modulate a rate of exchange of crosslinking of the polymer network.
