Ligand-orientation based fragment selection in STD NMR screening.

J Med Chem. 2015 Oct 22;

Abstract
While Saturation Transfer Difference (STD) is a widely used NMR method for ligand screening, the selection of specific binders requires the validation of the hits through competition experiments or orthogonal biophysical techniques. We show here that the quantitative STD analysis is a reliable and robust approach to discriminate between specific and nonspecific ligands, allowing selection of fragments that bind proteins with a privileged binding mode, in the absence of any structural data for the protein.

By fixing a paramagnetic lanthanide ion to a target protein, a pseudo-contact shift (PCS) and a paramagnetic relaxation enhancement (PRE) can be observed for both the target protein and its bound ligand. Based on PRE and PCS information, the bound ligand is then screened from the compound library and the structure of the ligandâ??protein complex is determined. PRE is an...	nmrlearner	Journal club	0	09-20-2011 05:02 AM
