Product Description:

2-Thiohistidine is a sulfur-containing derivative of the amino acid histidine, where the imidazole nitrogen is replaced by a sulfur atom. This structural modification imparts distinct chemical and biological properties compared to its parent compound. This compound is primarily utilized as a biochemical research tool. It serves as a precursor or intermediate in the synthesis of more complex molecules for biological studies. Its unique structure makes it of interest in probing enzyme mechanisms, particularly those involving histidine residues, and in the development of enzyme inhibitors or modulators. As a non-proteinogenic amino acid analog, 2-thiohistidine is investigated for its potential biological activities and interactions. It falls under the category of specialized amino acid derivatives used in life science research and pharmaceutical development.
