Fesik, Stephen W. 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.

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.

In addition to these structural studies, he developed a method for drug discovery called SAR by NMR and applied this method to identify and optimize ligands for binding to many protein drug targets. His research has also involved the use of siRNA for target identification and target validation. Fesik earned his Ph.D. in Medicinal Chemistry from the University of Connecticut and was a post doctoral associate …

Stephen W. Fesik, Ph.D. is the Orrin H. Ingram, II Chair in Cancer Research and a Discovery of potent nonpeptide inhibitors of stromelysin using SAR by NMR.

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. This individual will work closely with cell biologists and chemists and will clone, express and purify recombinant proteins, carry out fragment-based screen by NMR, co-crystallize target proteins with small-molecule inhibitors, interpret Structure Activity Relationships (SAR), and contribute to the discovery of new targets for cancer drug Mary J. Harner*, Andreas O. Frank*,†, and Stephen W. Fesik Department of Biochemistry, Vanderbilt University School of Medicine, Nashville, TN, USA Abstract Nuclear magnetic resonance (NMR) spectroscopy has evolved into a powerful tool for fragment-based drug discovery over the last two decades.

In this regard, we have developed an NMR‐based approach (SAR by ILOEs) that enables the identification of high affinity ligands for a given protein target without the need of a specific assay. molecules, Fesik used computer modeling of the NMR-derived structure of FKBP with the untethered ligands. The best of the five final products had a binding constant (K d) of 19 nM, very much better than the K d s of the starting compounds (2 mM and 100 mM). The genesis of an idea The conceptual parent of SAR by NMR is combinatorial chemistry, Nov 15, 2010 · Here, we report the use of SAR by NMR and structure-based drug design in the discovery of selective inhibitors of Bcl-2 based on a diphenylmethane core. These compounds have nanomolar potency against Bcl-2, but exhibit >1000-fold and >28-fold selectivity over Bcl-x L and Mcl-1, respectively, and could serve as a useful starting point for NMR is a powerful tool for fragment screening and can be tailored to suit the protein target due to the availability of many different techniques. This tool is particularly useful in initial library screening however, identification of the binding mode of fragments will be limited by the protein target and whether peaks have been assigned in Prior to joining Vanderbilt in May, 2009, Dr. Fesik was the Divisional Vice President of Cancer Research at Abbott (2000-2009) where he built a pipeline of compounds that are showing promising anti-cancer activities in early stage clinical trials.

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 approach is called "SAR by NMR" because structure-activity relationships (SAR) are obtained from NMR. Definition Structure-activity relationship (SAR) by NMR is a technique developed in 1996 by Stephen Fesik at Abbot Laboratories. SAR by NMR is the first experimental demonstration of the fragment-based approach to drug discovery. The method uses NMR spectroscopy to probe the surface area surrounding a protein’s active site for ligand binders. 1. J Biomol NMR. 1993 May;3(3):261-9. NMR structure-based drug design.
