Abstract
A new set of endogenous mediators known as novel catecholamines has recently been described. The novel catecholamines include the group of 6-nitrocatecholamines (6-NCT) and derivatives with a cyanide group, such as 6-cyanodopamine (6-CD), constituting a broad family of catecholamine-derived mediators.The synthesis of 6-NCT occurs through the nitration of catecholamines by nitric oxide. 6-…
