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. WebTherefore the photokinetic factor has been defined. For this reason the following discussion seems necessary. In contrast to apparent photochemical quantum yields a true one depends neither on the moment at which it is determined nor on the absorption of the … Manu Vaishakh, V.P.N.
