    • Recursive partitioning-centered virtual screening (RPCVS) protocol is a term used in the text and in Figures 1, 2, and 3 to outline a three-step virtual screening procedure consisting of: 1) the application of Lipinski's rule of five (due to the high lipophilicity of the mycobacterial cell wall, log P was raised from 5 to 6), 2) the classification of compounds according to the recursive partitioning (RP) model, and 3) the computation of the penalty factor.

    • Aimed at elaborating a ligand-based virtual screening procedure, the objective of the first part of our work was the collection of a huge set of compounds along with their MIC values suitable for the generation of a statistical model, without reference to their (known or unknown) mechanisms of action. Consistent with this collection criterion, we analyzed data by means of a recursive partitioning technique, which is able, in principle, not only to account for multiple structurally diverse classes of compounds and to tolerate a certain amount of erroneous input data, but also to deal with different mechanisms of action, as reported in: a) D.

    • Penalty factor values in the SL range from 0.373 to 5.530. The threshold value of the penalty factors was arbitrarily defined, so as to result in a reasonably restricted number of selected compounds. 668 compounds of the SL had a penalty factor value less than 1 (about 13%).
