Copper-Catalyzed Click Chemistry and Bioorthogonal Peptide Synthesis
This community develops rapid, high-yield chemical reactions—primarily copper-catalyzed azide-alkyne cycloaddition—to link molecules together in biological settings, creating new therapeutic agents and diagnostic tools.
The work centers on the synthesis of 1,2,3-triazoles via "click chemistry," a method favored for its efficiency and compatibility with living systems. Recurring themes include the design of artificial metalloenzymes to catalyze these reactions in aqueous environments and the application of bioorthogonal strategies for labeling proteins and peptides. A significant portion of the research focuses on the construction of macrocyclic peptides and antibody-drug conjugates, often evaluating their biological activity as anticancer agents or antimicrobials. The methodology emphasizes regioselective synthesis and one-pot reactions to streamline the production of complex derivatives for medical and biological evaluation.
The community is most prominent in copper research, accounting for 40.0% of all copper-related papers tracked, and 30.0% of palladium research. Bromine research also shows a 40.0% share, reflecting the frequent use of brominated reagents in these synthetic pathways.
The community comprises 6,616 papers, predominantly published in Angewandte Chemie International Edition, the Journal of the American Chemical Society, and Synthesis.
Recent work continues to refine these methods, with new papers describing nanosized metal-organic frameworks for efficient azide-alkyne cycloaddition, aqueous solid-phase peptide synthesis, and the development of bioorthogonal probes for imaging in living systems.
