Caged amino acids for visible-light photodelivery

We present a photocleavable protecting group based on ruthenium bipyridyl complexes and suitable for amino acid photodelivery. We discuss the photochemical properties of the caged glutamate, which is a major neurotransmitter in the CNS. The molar absorptivity for the caged glutamate at 450 nm is ε =...
