Photocaged compounds
WebAbstract. We report a new synthetic route to a series of α-carboxynitrobenzyl photocaged L-aspartates for application in time-resolved structural biology.The resulting compounds were characterised in terms of UV/Vis absorption properties, aqueous solubility and stability, and photocleavage rates (τ = μs to ms) and quantum yields (φ = 0.05 to 0.14). WebMay 21, 2024 · We designed a new caging group that can be photoactivated only in the presence of a non-endogenous enzyme when exposed to 405 nm light. Because cells or tissues can be genetically tagged by an exogenously expressed enzyme, this novel method can serve as a strategy for adding targeting abilities to photocaged compounds.
