摘要
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 epsilon = 4200 M(-1)cm(-1) and its quantum yield of photorelease at 450 mn is Phi(PD) = 0.035, which is about 17 times higher than that of the most active organic caged compound at this wavelength. Similar figures are obtained for other alpha-amino acids. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008).
