Nitric oxide (NO), which is synthesized from L-arginine by nitric oxide synthase (NOS) in mammals, acts as a signal molecule for vasorelaxation, cytotoxicity and neurotransmission. The difficulty in handling of a gaseous and labile NO causes problems with the effective and precise studies using NO. The increasing interest in the biological roles of NO requires the use of NO donors which releases NO under the various desirable conditions. We systematized the most commonly used NO donors in this article to support the biological investigation. NO donors were classified according to the functional groups based on NO-donating characteristics. The preparation, chemical properties and NO-donating ability of these NO donors are summarized. It is particularly described in some detail on the stability both as a solid and in solution and the handling of the compounds.

UI MeSH Term Description Entries
D009569 Nitric Oxide A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D020030 Nitric Oxide Donors A diverse group of agents, with unique chemical structures and biochemical requirements, which generate NITRIC OXIDE. These compounds have been used in the treatment of cardiovascular diseases and the management of acute myocardial infarction, acute and chronic congestive heart failure, and surgical control of blood pressure.
