Four Levels of Wavelength-Selective Uncaging for Oligonucleotides

Abstract

In this study the new nucleobase-caged nucleotides dT(NpHP) and dT(DEACM) are introduced. Together with two other caging groups (NDBF and NPP) this results in four layers of wavelength-selective uncaging for oligonucleotides, sequentially going from 505 to 440 nm, 365 nm, and finally to 313 nm for the photolysis reaction.
