Sar9, Met (O2)11-Substance P is a neurokinin-1 receptor agonist. It is an analog of the naturally occurring human neuropeptide Substance P, which can be found throughout the body, including in

SAR by NMR may best be described as a method for totally NMR driven ligand design. Furthermore, the 1D technique may be used to directly identify ligands from a complex mixture of compounds, reducing the amount of time needed for NMR-based screening. Another requirement of SAR by NMR (or any method used for detecting weakly bound ligands) is that the compounds must be soluble at millimolar concentrations in aqueous solution.
