METHODS FOR IDENTIFYING LIGANDS USING COMPETITIVE BINDING 1H NMR EXPERIMENTS

摘要

A method of identifying a ligand to a target molecule that includes: providing a reference compound that interacts with the target molecule; collecting a 1 D 1H nuclear magnetic resonance spectrum of the reference compound in the presence of the target molecule; providing a plurality of test samples, each test sample including at least one test compound; collecting a 1 D 1H nuclear magnetic resonance spectrum of the reference compound in the presence of each test sample and the target molecule; comparing the spectrum of the reference compound in the presence of the target molecule to the spectrum of the reference compound in the presence of each test sample and the target molecule to determine a change in one or more of the reference compound resonances; and identifying at least one test compound that interacts with the target molecule, wherein the test compound displaces the reference compound.
