The progress in computational techniques throughout the past decade enables the use of in silico approaches to predict several ADME-Tox properties of small organic molecules or drug candidates in parallel or prior to experimental investigations. In particular, the availability of three-dimensional structures of some proteins that are key for ADME-Tox events makes possible to perform protein structure-based computations to complement or to go beyond traditional QSAR modeling. We will briefly discuss current in silico methods for ADME-Tox prediction with a focus on drug metabolizing enzymes. Applying structure-based approach to drug metabolizing enzymes is a challenging process because they usually have flexible binding sites. We developed in silico structure-based protocol to gain mechanistic insights from probing small molecules binding to two metabolizing enzymes: the phase I, cytochrome P450 2D6 (CYP2D6), and the phase II, sulfotransferase. We used molecular dynamics to generate suitable diverse protein conformations and protein-ligand docking to discriminate binders and nonbinders in large chemical compound collections for CYP2D6 and sulfotransferase. Our results suggest that structure-based in silico approach is useful for prioritizing compounds interacting with drug metabolizing enzymes and may be used to go 'beyond QSAR profiling' of drug candidates to assist decision-making in drug discovery.
