摘要

Chemical structures and properties of diazeniumdiolates that make them so excellent for designing materials capable of targeting reliable and controllable fluxes of bioactive NO have become one of the forefronts and highlights of novel NO donors. The toxicity and poor biocompatibility of the nucleophile (polyamines) and the formation of potentially carcinogenic nitrosoamine are the problems associated with its successful clinical application. Recent research progress on targeting nitric oxide releasing materials is reviewed, basing on the three strategies of delivering NO specifically to a targeted site, including polymer-based diazeniumdiolates, enzyme activated diazeniumdiolates. and photosensitive diazeniumdiolates.
