DMax Chemistry Assistant™ automatically finds, formulates, validates and shows scientific hypotheses that best match small molecule screening data. Each discovered hypothesis suggests a relationship between molecule structure and biological activity and thus contributes to the researcher's insight in the underlying mechanism-of-action. In addition, the inferred hypotheses are combined into an auto-extracted expert system for in-silico screening and prioritization of large compound libraries. For each predicted score/rank, researchers can drill down to potential explanations and further down to the previously screened reference molecules that back those explanations.

DMax Chemistry Assistant can construct descriptive and predictive SAR models referring to substructures of arbitrary complexity, not just pre-defined fingerprints.

METEOR originally resulted from a three year research project to develop a computer system for the intelligent prediction of the metabolic fate of xenobiotic chemicals. The software is continually developed alongside experts from various industry and academic sectors, with knowledge of biotransformations covering phase I and phase II metabolism. The software predicts the metabolic fate of a parent compound, and it also evaluates the likelihood that each predicted metabolite could be found in vivo. This evaluation considers physicochemical parameters, such as logP. Metabolites can be restricted to those most likely to be of interest by user defined controls. These include:

  • Selection of confidence levels for metabolite generation
  • Sequence termination at excretable metabolites.
  • External link to ClogP
  • The potential to make species specific predictions
  • Restriction to either Phase I or Phase II processes

The report for a query compound contains specific literature references, and links to external commercial metabolism databases are available. METEOR can also perform alongside DEREK for Windows, allowing a fast assessment of the likelihood of potential metabolites being toxic. For further information contact:

Vcharge calculates accurate, conformation-independent, "ab initio-like" partial atomic charges for an SDfile of drug-like compounds in ~0.1 per compound. It is useful for a wide range of modeling and QSAR applications, and is available for Windows and Linux. Vcharge is an electronegativity equalization method in which the electronegativity of each atom depends upon its atomic number, hybridization, and bonding environment within the molecule. Electronegativities and hardnesses are averaged over alternate resonance forms of the molecule, which are automatically detected. The VC/2004 parameterization of Vcharge yields charges that accurately reproduce Hartree-Fock 6-31G* potentials at CHELPG sampling points, and that are strikingly similar to those in widely used force fields, such as AMBER and CHARMM22. The method is described in the following paper: Fast assignment of accurate partial atomic charges. An electronegativity equalization method that accounts for alternate resonance forms; Gilson,M.K., Gilson,H.S.R. & Potter,M.J.; J. Chem. Inf. Comput. Sci. 2003, 43(6), 1982-1997. More information is available at http://www.verachem.com/Vcharge, and the program can be tried on-line at http://www.verachem.com/Vcharge2.html
