It was the aim of this study to synthesize and characterize a novel hyaluronic acid-cysteine ethyl ester (HA-Cys) conjugate providing improved mucoadhesive properties and a significantly lowered biodegradation rate. Mediated by carbodiimide and N-hydroxysuccinimide, L-cysteine ethyl ester hydrochloride was covalently

S-Nitrosothiols from low-molecular-mass and high-molecular-mass thiols, including glutathione, albumin and hemoglobin, are endogenous potent vasodilators and inhibitors of platelet aggregation. By utilizing the S-transnitrosation reaction and by using the lipophilic (pK(L) 0.78) and strong nucleophilic synthetic thiol N-acetyl cysteine ethyl

We report an investigation of the reaction between (S)-nitroso-l-cysteine ethyl ester and l-cysteine ethyl ester as a model of physiologically relevant transnitrosation processes. Our theoretical and experimental evidence clearly supports the existence of a nitroxyl disulfide intermediate in solution.

Glutathione (GSH) is the main non-enzymatic defence against oxidative stress and is a critical intracellular component required for oocyte maturation. In the present study, several modulators of intracellular GSH were assessed for their effect on the in vitro maturation (IVM)

The mutagenicity of thiol (SH)-containing compounds was tested in Salmonella typhimurium TA102 in the liquid preincubation method. Cysteinyl-glycine (CG), cysteine ethyl ester (CEE), L- and D-penicillamine (PA), cysteine (Cys) and glutathione (GSH) were mutagenic to strain TA102 without metabolic activation.
