PHOTOINDUCED ELECTRON-TRANSFER FOR PYRENESULFONAMIDE CONJUGATES OF TRYPTOPHAN-CONTAINING PEPTIDES - MITIGATION OF FLUOROPROBE BEHAVIOR IN N-TERMINAL LABELING EXPERIMENTS
G. Jones et al., PHOTOINDUCED ELECTRON-TRANSFER FOR PYRENESULFONAMIDE CONJUGATES OF TRYPTOPHAN-CONTAINING PEPTIDES - MITIGATION OF FLUOROPROBE BEHAVIOR IN N-TERMINAL LABELING EXPERIMENTS, Bioorganic & medicinal chemistry letters, 5(20), 1995, pp. 2385-2390
The (nitro)pyrenesulfonamide group has been attached to the N-terminus
of tryptophan and tryptophan-containing peptides. Intramolecular elec
tron transfer between pyrene and Trp indole side chains, observed by f
luorescence quenching and laser flash photolysis, depends on the spaci
ng between Pyr and Trp moieties and the strength of the electron accep
tor.
