Live-Cell Protein Modification by Boronate-Assisted Hydroxamic Acid Catalysis

Selective methods for introducing protein post-translational modifications (PTMs) within living cells have proven valuable for interrogating their biological function. In contrast to enzymatic methods, abiotic catalysis should offer access to diverse and new-to-nature PTMs. Herein, we report the boronate-assisted hydroxamic acid (BAHA) catalyst system, which comprises a protein ligand, a hydroxamic acid Lewis base, and a diol moiety. In concert with a boronic acid-bearing acyl donor, our catalyst leverages a local molarity effect to promote acyl transfer to a target lysine residue. Our catalyst system employs micromolar reagent concentrations and affords minimal off-target protein reactivity. Critically, BAHA is resistant to glutathione, a metabolite which has hampered many efforts toward abiotic chemistry within living cells. To showcase this methodology, we installed a variety of acyl groups inE. colidihydrofolate reductase expressed within human cells. Our results further establish the well-known boronic acid-diol complexation as abona fidebio-orthogonal reaction with applications in chemical biology and in-cell catalysis.

Dissociative reactions of benzonorbornadienes with tetrazines: Scope of leaving groups and mechanistic insights

Bioorthogonal dissociative reactions boast diverse potential applications in chemical biology and drug delivery. The reaction of benzonorbornadienes with tetrazines to release amines from carbamate leaving groups was recently introduced as a bioorthogonal bond-cleavage reaction. The present study aimed at investigating the scope of leaving groups that are compatible with benzonorbornadienes. Synthesis of several benzonorbornadienes with different releasable groups is reported, and the reaction of these molecules with tetrazine was found to be rapid and afforded high release yields. The tetrazine-induced release of molecules proceeds in a cascade of steps including inverse-electron demand cycloaddition and cycloreversion reactions that form unstable isoindoles/isobenzofuran intermediates and spontaneously eliminate a leaving group of interest. In the case of oxygen-bridged BNBDs at room temperature, we observed the formation of an unproductive byproduct.
