Abstract

AbstractA photo-labile compound that is bioinactive but upon irradiation with light yields bioactive species, is called as “caged compound” (1) (see Scheme 1). Photolysis of caged compounds generating bioactive species, i.e., “uncaging,” has become a general method to produce a desired amount of bioactive species in a specific time interval at desired place or area of the target biological systems (1,2). This chapter deals with two caged free radicals: a caged hydroxyl radical, i.e., photo-Fenton reagent, and caged nitric oxides (NOs). Uncaging of these caged free radicals yield hydroxyl radical and NO, respectively, which are believed to be associated with free-radical tissue damage.
