Preparation of a new combination of cysteine

Cysteine as a semi-essential amino acid can be biosynthesized in humans. Amino acid serine starts biosynthesized, and the sulfur is derived from methionine. Its thiol side easily oxidized, and play a nucleophile role in enzymatic reactions. Because of this high reactivity, the thiol group of cysteine has a lot of biological functions.In this research the preparation of a new combination of cysteine under reflux condition is reported. Molecular structure of the synthesized compound was determined and confirmed by Nuclear magnetic resonance and feurier-transform infrared spectroscopy methods. The effects of different parameters have been studied in vitro and the optimum values including time and temperature were estimated. According to the applications of urea compounds structure and cysteine, this derivative could be useful in formulation design of new pro-drugs.
