Author information: (1)Pharmaceutical Discovery Division, Abbott Laboratories, Abbott Park, Il 60064. NMR is a useful tool for rapidly determining the conformations of receptor-bound ligands and identifying those portions of the ligand in contact with the receptor. Mar 10, 2006 · Reverse chemical genetics is an emerging technique that makes use of small molecule inhibitors to characterize how a protein functions. 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.

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. While NMR has been traditionally used to This approach of fragment-based drug design relies on a technique pioneered by Fesik, known as SAR by NMR (structure-activity relationship by nuclear magnetic resonance), which led to the discovery of inhibitors against the previously undruggable Bcl-2 family of proteins. Nov 21, 2013 · Fesik’s team uses a method he developed called SAR by NMR (structure-activity relationships by nuclear magnetic resonance). The investigators use NMR methods to screen libraries of small chemical fragments for binding to a target protein. Then they use NMR or X-ray crystallography to determine how any chemical “hits” bind to the target.

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

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. 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.

Our approach is of general applicability and could result very powerful in reverse chemical‐genetics studies, target validation, and lead discovery. activity relationship (SAR) from the initial chemical leads. NMR has been extensively used to evaluate ligand binding with an obvious utility in structure-based drug discovery and design.7-10 The “SAR by NMR” method, previously described by Hajduk et al., illustrates the utility of NMR to screen small molecules for 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. Using an NMR-based screen, we tested compounds for binding to the DNA-binding domain of the HPV-E2 protein. Three classes of compounds were identified which bound to two distinct sites on the protein. Definition. Structure-activity relationship (SAR) by NMR is a technique developed in 1996 by Stephen Fesik at Abbot Laboratories.
