NMR Screening SAR by NMR: (see Chemical Shift Perturbation in Biomolecular complexes). Affinity NMR: based on translational diffusion differences. Examples are the NOE pumping experiment ( 98JACS10258 and 03JAFC1988 ). Change of relaxation properties Interligand NOEs. A particular example is the Reverse NOE pumping experiment. Transferred NOEs Saturation Transfer Difference Spin-labels WATER-LOGSY experiment: The large bulk water magnetization is partially transferred via the protein-ligand complex to the free ligand. 19F NMR Experiments: 03JACS7696 and 03JACS14620 Biomolecular complexes Protein-Drug DNA-Drug RNA-Drug General Reading NMR in drug discovery ( 00DDT230 , 99QRB211 , 02PROG187 and 04CR3641 ) Drug metabolism studied using NMR ( 00ENC375 ) NMR based approaches for lead generation in drug discovery ( 01METH202 , 05METH549 and 05METH571 ) Flow-injection NMR techniques in drug discovery ( 01METH230 ) Determining the overall size of small molecules mistures for high troughput NMR screening ( 05JB243-31 )
