N-Fmoc-L-proline-4-spiro-3-(3H-diazirine)

Uses

Fmoc-L-photo-proline is a diazirine-containing, Fmoc-protected proline amino acid and multifunctional probe building blocks. Its incorporation into peptides or small-molecule probes and tools allows for photoaffinity labeling of cellular targets and protein-protein interactions upon UV light (～360 nm) irradiation to form a covalent bond. This and other multifunctional probe building blocks will continue to accelerate drug discovery research for probing cellular mechanisms, target ID/validation, and understanding traditionally undruggable targets. An unprotected version is also available as 907286.
