The chemistries of S-nitroso-DL-penicillamine (SNAP) and S-nitrosoglutathione (GSNO) in relation to their ability to relax vascular smooth muscle and prevent platelet aggregation have been investigated. Metal ion catalysis greatly accelerates the decomposition of SNAP, but has little effect on GSNO.
N-Acetyl-DL-penicillamine (IIIb), a structural analog of N-acetyl-L-cysteine (IIIa), did not protect mice from lethal doses of acetaminophen (I), whereas IIIa offered protection. This lack of efficacy of IIIb probably is due to the decreased nucleophilicity of its sulfhydryl group compared to that o
