Decomposition of copper-amino acid complexes by sodium sulfide

Sodium sulfide very efficiently removes copper from protected amino acid-copper complexes. The copper in the amino acid complex was reduced to insoluble cuprous sulfide and the free amino acid was released in pure form. This method is very convenient and rapid, requiring only 5-10 min and 0.55-0.75 equiv of sodium sulfide.

L-Arginine analogs as alternate substrates for nitric oxide synthase

The L-arginine analogs, Nδ-methyl-L-arginine (δMA) and L-canavanine, were used to probe the role of the Nδ nitrogen of l-arginine in the reaction catalyzed by nitric oxide synthase (NOS). δMA was synthesized and found to be a partial
