Application

H-L-Photo-leucine HCl is a diazirine-containing leucine 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. An Fmoc-protected version is also available as 907391.

A photoactivated, site-selective conjugation of poly(ethylene glycol) (PEG) to the glutathione (GSH) binding pocket of glutathione S-transferase (GST) is described. To achieve this, a GSH analogue (GSH-BP) was designed and chemically synthesized with three functionalities: (1) the binding affinity of
