L-Phenylalanine, 4-[3-(trifluoromethyl)-3H-diazirin-3-yl]-

Uses

H-L-Photo-Phe-OH is a diazirine-containing phenylalanine amino acid and multifunctional
photo-crosslinker. 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.
