WebApr 29, 2016 · In this study, we report on the design, synthesis, photokinetic properties and in vitro evaluation of photoactivatable caged prodrugs for the receptor tyrosine kinase VEGFR-2. Highly potent VEGFR-2 inhibitors 1 and 3 were caged by introduction of a photoremovable protecting group (PPG) to yield the caged prodrugs 4 and 5. As expected, … Web2. The chemistry of peptide photocaging Several common features are shared among most PPGs [2, 7]. Yet for peptide photocaging, additional restrictions should be imposed. First, the PPG should be chemically stable in aqueous and organic solvents, and it should endure repeated treatment by reagents used for
