The effects of 1 mM L-cysteine on sodium nitrite-, 3-morpholinosydnonimine (SIN-1)- and acetylcholine-induced relaxation and cyclic GMP accumulation were studied in isolated noradrenaline-precontracted rat mesenteric arterial rings. L-Cysteine augmented the relaxation and cyclic GMP increase induced by sodium nitrate and SIN-1 but not those induced by acetylcholine. The effects of L-cysteine on relaxation were independent of the presence of intact endothelium. The results suggest that L-cysteine protects exogenously released nitric oxide.
