Substance P-methyl ester is a chemically modified derivative of the neuropeptide Substance P, where the C-terminal carboxylic acid group is converted to a methyl ester. This alteration enhances stability and may influence receptor interaction compared to the native peptide. It is commonly utilized in pharmacological and biochemical studies to investigate the role of structural modifications in peptide activity, metabolism, and delivery, as well as to explore potential therapeutic applications requiring prolonged peptide stability.
