normal mode analysis and molecular dynamics simulation CITY UNIVERSITY OF NEW YORK Lei Xie ChiuSee HongOne of the unaddressed challenges in drug discovery is that drug potency measured by protein-ligand binding affinity, such as ICand Kin vitro, is not correlated with drug activity in vivo. ...
The computational modeling of ligand–protein binding thermodynamics is reviewed from the perspective of drug discovery. Methods for estimating the binding free energy and its components are presented in a hierarchy of decreasing complexity and computational requirement. Potentially accurate molecular dynamics...
Understanding protein–drug binding mechanisms, and characterizing their thermodynamics and kinetics are fundamental prerequisites to developing effective drug discovery procedures and, indeed, to developing effective drugs. It has been demonstrated that the duration of the pharmacological action1,2,3,4of a...

drug absorption, hepatic metabolism, tissue distribution, and protein binding, which complicate interpretation of any change, or lack of change in drug half-life. Furthermore, it is now apparent that the efficiency with which a drug is metabolised by the liver, the extent of binding to blood ...
Computational Predictions of Drug-Protein Binding Kinetics with a Hybrid Molecular Dynamics, Brownian Dynamics, and Milestoning Approachdoi:10.1016/j.bpj.2018.11.3020Jagger, Benjamin R.Lee, Christopher T.McCammon, J. AndrewAmaro, Rommie E.
No correlation was found between penetration rates and plasma protein binding, but at equilibrium, the ratio between CSF and total plasma concentrations was almost equal to the free fraction of drug in plasma. A significant correlation was found between penetration rate and the benzene/buffer ...

G protein-coupled receptorsDrug-target binding kinetics are suggested to be important parameters for the prediction ofdrug-efficacy. For G protein-coupled receptors (GPCRs), the binding kinetics of ligands are typically determined using association binding experiments in competition with radiolabelled ...
Measuring the binding kinetics of single proteins represents one of the most important and challenging tasks in protein analysis. Here we show that this is possible using a surface plasmon resonance (SPR) scattering technique. SPR is a popular label-free
