Structure-based drug development suffers from high attrition rates due to the poor activity of lead compounds in cellular and animal models caused by low cell penetrance, off-target binding or changes in the conformation of the target protein in the cellular environment. The latter two effects cause a change in the apparent binding affinity of the compound, which is indirectly assessed by cellular activity assays. To date, direct measurement of the intracellular binding affinity remains a...

Determination of ligand binding modes in weak proteinâ??ligand complexes using sparse NMR data
Determination of ligand binding modes in weak proteinâ??ligand complexes using sparse NMR data
Abstract
We describe a general approach to determine the binding pose of small molecules in weakly bound proteinâ??ligand complexes by deriving distance constraints between the ligand and methyl groups from all methyl-containing residues of the protein. We demonstrate that using a single sample, which can be prepared without the use of expensive precursors, it is possible to generate high-resolution data rapidly and obtain the resonance assignments of...
