The invention aims in establishing a method for modifying biomolecules using a reaction that efficiently modifies biomolecules and is widely applicable. The invention thus provides a cyclic compound containing two triazole rings formed by adding and ligating an azide compound possessing an azido group to each of the two carbon-carbon triple bond sites of an eight-membered cyclic skeleton of a cyclic diyne compound by a double click reaction; a method for producing a cyclic compound using a double click reaction; and a method for modifying biomolecules.

azide-reactive strained dialkyne reagents. To demonstrate their extensive utility, we applied our novel dialkynes to a double strain-promoted macrocyclisation strategy to generate functionalised p53-based stapled peptides for inhibiting the oncogenic p53-MDM2 interaction. These functionalised stapled peptides bind MDM2 with low nanomolar affinity and show p53 activation in a cellular environment. Overall, our highly
The clickabilities of various alkenyl and alkyl azides in the strain-promoted cycloaddition with dibenzo-fused cyclooctynes were investigated. Although alkenyl azides generally exhibited lower clickabilities than those of alkyl azides, a sterically-hindered alkenyl azide showed high reactivity comparable with those of alkyl azides. Theoretical analyses indicated that these unique reactivities are derived from the frontier molecular orbital interactions and distortability of the azido groups.
