A caged, photolabile Nitric Oxide donor, BNN5NA is useful for delivering nitric oxide into intracellular compartments in microsecond time scale without any cytotoxic effects. Upon irradiation these donors produce two NO molecules per molecule of BNN. Thiols present in biological systems do not interfere with the release of NO from these caged compounds. They are stable over a wide physiological range of pH.
