Abstract A nuclear magnetic resonance (NMR)-based method is described in which small organic molecules that bind to proximal subsites of a protein are identified, optimized, and linked together to SAR by NMR was reported in 1996 by Shuker, Hajduk, Meadows, and Fesik as a fragment assembly approach to inhibitor design, using NMR as a structural guide. It is essentially a five-step method that involves screening for weak- binding fragments in two binding sites. The method, called SAR by NMR (for structure−activity relationships by nuclear magnetic resonance), involves the identification, optimization, and linking of compounds that bind to proximal sites on a protein. STRUCTURE-ACTIVITY RELATIONSHIPS (SAR) BY NMR SAR by NMR is a CSM approach to ligand optimization developed by Fesik and coworkers at Abbott Laboratories.6 In this technique, two ligands occupying distinct, proximal sites are identified by 15N-HSQC CSM. Optimization of the two ligands and subsequent covalent tethering of the two SAR-by-NMR is a method for generating systematically lead compounds in the early stages of a drug finding This is a preview of subscription content, log in to check access. Inspired by the protein-observed NMR approach using 1 H– 15 N-HSQC NMR which detects chemical shift perturbations of 15 N-labeled amides, we have applied a complementary protein-observed 19 F NMR approach using 19 F-labeled side-chains that are enriched at protein–protein-interaction interfaces.
