10/03/2006 Nuclear magnetic resonance (NMR) spectroscopy has evolved into a powerful tool for fragment-based drug discovery over the last two decades. While NMR has been traditionally used to structure-activity relationship (SAR) studies of the attained fragment hits proceed quickly because analogs are simpler to prepare synthetically or can be purchased commercially due to their smaller size and lower complexity. … Solution Structure of the Anti-apoptotic Protein Bcl-xL in Complex with "SAR by NMR" Ligands.

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 produce high-affinity ligands. The approach is called "SAR by NMR" because structure-activity relationships (SAR) are obtained from NMR.

This paper presents the Jigsaw algorithm, a novel highthroughput, automated approach to protein structure characterization with nuclear magnetic resonance (NMR). Jigsaw applies graph algorithms and probabilistic reasoning techniques, enforcing first-principles consistency rules in order to overcome a 5-10 % signal-to-noise ratio.

The solid state NMR technique can give information on the structure, especially the conformation of drugs and excipients in drug formulations. Recently, SAR by NMR, introduced by Fesik, impressively demonstrated the potential of NMR spectroscopy in drug development and in the characterization of the interaction between large molecules and ligands.

The approach is called "SAR by NMR" because structure-activity relationships (SAR) are obtained from NMR. Application of NMR-based screening yielded an initial biaryl acid with an affinity (K(d)) of approximately 300 microM for the protein. Following the classical "SAR by NMR" approach, a second-site ligand was identified that bound proximal to the first-site ligand in the hydrophobic groove. Jan 29, 2013 · Fesik was one of the inventors of the SAR by NMR technique that led to navitoclax, and in this case the team used a similar approach, screening a fairly large fragment library (> 13,800 compounds) in pools of 12 using 1 H-15 N HMQC NMR. This produced 132 hits, of which two chemical classes were pursued. From an NMR-based screen of a large fragment library, several distinct chemical scaffolds that bind to Mcl-1 were discovered. Here, we describe the discovery of potent tricyclic 2-indole carboxylic acid inhibitors that exhibit single digit nanomolar binding affinity to Mcl-1 and greater than 1700-fold selectivity over Bcl-xL and greater than The solid state NMR technique can give information on the structure, especially the conformation of drugs and excipients in drug formulations. Recently, SAR by NMR, introduced by Fesik, impressively demonstrated the potential of NMR spectroscopy in drug development and in the characterization of the interaction between large molecules and ligands.

Office: 634-A Robinson Research Building. Laboratory: 802/804 Robinson Research Building. 04/08/2011 Definition NMR can be used as a method for monitoring protein-ligand interactions, either by detecting protein signals or the signals of the ligand. The detection of protein signals requires isotope labeling, usually with 15 N, whereby ligand observed techniques maybe applied without any labeling. With the development of higher sensitivity cold NMR probes, ligand-based NMR methods can be successfully applied to a majority of projects found in a pharmaceutical pipeline. Having matured from the original concepts such as SAR by NMR (Shuker, S. B., Hajduk, P. J., Meadows, R. P., Fesik, S. W. (1996) Discovering high-affinity ligands for proteins: SAR by NMR.
