Determination of the binding mechanism of histone deacetylase inhibitors

The understanding of the mode of action of active substances and how this is coupled to the biological response is of utmost importance for the optimization of drug candidates. This article contains a comprehensive collection of methods and protocols that enables the elucidation of the binding mechanism of inhibitors to histone deacetylases. All available equilibrium and kinetic data can be beneficially combined in a data analysis procedure called Integrated Global Fit analysis eventually yielding the most likely binding mechanism.

Abstract

This article places its focus on methods and tools enabling the elucidation of the mechanism by which ligands, small molecule inhibitors or substrates, interact with zinc containing bacterial or human members of the histone deacetylase family (HDACs). These methods include biochemical and biophysical approaches and can be subdivided into equilibrium and kinetic methods. More information about the exact mode of action can be obtained by combining these methods with specific mutant variants of the enzymes and/or series of structural similar ligands. All available equilibrium and kinetic data including additional information from 3D‐structures of HDAC‐ligand complexes can be beneficially combined in a data analysis procedure called Integrated Global Fit analysis eventually providing the most likely binding mechanism.
