Kinetic parameters have been measured for coupled nucleophilic and solvolytic reactions of 2,2,2-trifluoroethanesulfonyl (tresyl)-modified poly(ethylene glycol) based on a system of coupled differential equations implied by recently proposed elementary reaction mechanisms. Fitted kinetic parameters were found to be strong functions

The aim of this study was to improve the performance of affinity gels containing glycyl-D-phenylalanine (Gly-D-Phe) as a ligand to thermolysin. Gly-D-Phe was immobilized to the resin through spacers of varying chain lengths. The resulting affinity gels had spacer chain

Natively unfolded phenylalanine-glycine (FG)-repeat domains are alleged to form the physical constituents of the selective barrier-gate in nuclear pore complexes during nucleocytoplasmic transport. Presently, the biophysical mechanism behind the selective gate remains speculative because of a lack of information regarding

Oil-based depot formulations may constitute a future delivery method for small peptides. Thus, a requirement is attainment of sufficient oil solubility for such active compounds. A model dipeptide (Gly-Phe) has been converted into lipophilic prodrugs by esterification at the C-terminal
