Abstract

The binding affinity of some novel 1,4-dihy-dropyridine-3,5-dicarboxamides to enoyl-ACP reductase (InhA) from M. tuberculosis was studied by the docking method. A molecular dynamics simulation lasting 230 ns in total was performed for 19 ligand-enzyme complexes to calculate the binding free energies of these ligands to the enzyme. All of the studied compounds stayed in the active site. An energetics analysis revealed that the van der Waals share is more important than electrostatic in binding of all ligands to the active site. © 2011 Springer-Verlag.
