With the use of an NMR-based method, potent (IC50 < 25 nM) nonpeptide inhibitors of the matrix metalloproteinase stromelysin (MMP-3) were discovered. 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. Using this technique, two ligands that bind weakly to stromelysin (acetohydroxamic acid, K-D = 17 mM; 3-(cyanomethyl)-4'-hydroxybiphenyl, K-D = 0.02 mM) were identified. On the basis of NMR-derived structural information, the two fragments were connected to produce a 15 nM inhibitor of this enzyme. This compound was rapidly discovered (less than 6 months) and required only a minimal amount of chemical synthesis. These studies indicate that the SAR by NMR method can be effectively applied to enzymes to yield potent lead inhibitors-an important part of the drug discovery process.
