BCN, with free hydroxymethyl group

BCN, also known as bicyclo[6.1.0]non-4-yne, is a copper-free click chemistry probe that enables highly efficient and completely orthogonal bioconjugation to complex macromolecules including peptides, nucleic acids and proteins, including monoclonal antibodies.[1] The most recent and powerful application of this technology has been in the field of antibody-drug conjugates which results in targeted cancer therapeutics that have an improved therapeutic index, meaning they are more effective and better tolerated.[2] BCN is well-suited for aqueous bioconjugations due to its high reactivity with its azide counterpart and its high hydrophilicity, relative to other metal-free click chemistry probes.[3]
