alpha -carboxy caged compounds

摘要

The invention relates to caged compounds for the study of biological processes, where the caged compound has a photoremoveable alpha -carboxy-substituted o-nitrobenzyl group. Covalent attachment of the substituted o-nitrobenzyl to a parent compound yields a caged compound with biological and/or physical properties that are significantly altered from the original properties of the parent compound. Illumination of the caged compounds to cleave the photoremoveable group yields the parent compound with its original properties restored.
