Docking Applied to the Prediction of the Affinity of Compounds to P-Glycoprotein

Abstract EN

P-glycoprotein (P-gp) is involved in the transport of xenobiotic compounds and responsible for the decrease of the drug accumulation in multi-drug-resistant cells.

In this investigation we compare several docking algorithms in order to find the conditions that are able to discriminate between P-gp binders and nonbinders.

We built a comprehensive dataset of binders and nonbinders based on a careful analysis of the experimental data available in the literature, trying to overcome the discrepancy noticeable in the experimental results.

We found that Autodock Vina flexible docking is the best choice for the tested options.

The results will be useful to filter virtual screening results in the rational design of new drugs that are not expected to be expelled by P-gp.
