Chemical Methods for Peptide and Protein Backbone Cleavage
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...

A photoinduced, regio‐ and chemoselective γ‐alkylation of 2‐silyloxyfurans with a‐bromoketones was achieved by exploiting a photoredox catalytic process promoted by blue light. This approach provides practical and efficient access to chiral, ε‐ketobutenolides, in one step and high yields.
