The VEGA suite of programs: an versatile platform for cheminformatics and drug design projects

Abstract: The purpose of the paper is to offer an overview of the latest release of the VEGA suite of programs. This software has been constantly developed and freely released during the last 20 years and has now reached a significant diffusion and technology level as confirmed by the about 22500 registered users. While being primarily developed for drug design studies, the VEGA package includes cheminformatics and modeling features, which can be fruitfully utilized in various contexts of the computational chemistry.

“…Before descriptor calculation, the 3D structure of the collected molecules was optimized by applying a protocol of standardization, as follows: (i) the protonation state was simulated as compatible with the physiological condition (pH = 7.4) and tautomers were standardized by using the specific tool in the Maestro package, version 9.8.016 (Schrödinger Release 2016-4: Maestro, Schrödinger, LLC, New York, NY, 2016, USA); (ii) the conformational behavior was explored by a clustered procedure based on the Monte Carlo algorithms as implemented in the VEGA ZZ software [25], which generates 1000 conformers by randomly rotating the rotors and selects the lowest energy conformer; (iii) the 3D structures were refined by the semi-empirical method MOPAC 2016, [26] using the Hamiltonian operator PM7 [27] and preserving the existing chirality.…”

“…In detail, Table S1 reveals the remarkable role played by the XScore [24] and PLANTS [25] scoring functions (the latter here comprising also the primary scores). Table S1 also evidences the interesting role played by the scores encoding for non-polar interactions as exemplified by molecular lipophilic potential (MLP) [26] and the VEGA-based scores [27], which here correspond to the Lennard-Jones interaction energies as computed by using the CHARMM and CVFF force fields. Concerning the type of score values (in the models including the space descriptors), the best values play a prevailing role, while spread and mean values have a lesser and rather similar incidence.…”

“…Briefly, the protein structure was prepared by removing water solvents, crystallization additives, and the covalently bound N3 ligand. The hydrogen atoms were added by using the VEGA program [27] to remain compatible with physiological pH. The protein structure was then minimized using Namd2 [39] and by keeping the backbone atoms fixed to preserve the resolved folding.…”
