S-Nitrosylation, the addition of a nitrosyl group to cysteine thiols, regulates various protein functions to mediate nitric oxide (NO) bioactivity. Recent studies have demonstrated that selectivity in protein S-nitrosylation signaling pathways is conferre

S-Nitrosothiols and heme nitrosyl species are nitric oxide (NO)-derived metabolites that provide an endogenous reservoir of NO and also play roles in protein S-nitrosation, that is, transnitrosation of thiols (or thiolates) in proteins, thereby regulating protein functions and signal transduction pathways. Intriguingly, endogenous N-nitrosamines are present in similar abundance to S-nitrosothiols, and though they are thought to play similar physiological roles to S-nitrosothiols, their transnitrosation reactivities and their contribution to biological events are little understood. Herein we report aliphatic N-nitroso derivatives of 7-azabicyclo[2.2.1]heptanes, which do not act as NO donors themselves, but can transnitrosate thiols. On the basis of the calculated activation energies of transnitrosation and the aorta smooth-muscle relaxation activities of these N-nitrosamines, we present a possible scenario of S-transnitrosation from aliphatic N-nitrosamines, leading to indirect generation of NO.
