Abstract

See full text

The invention relates to a calculating method for molecular volume and shape comparison of two molecules. The method includes steps of loading in three-dimensional structure information of a first molecule, the three-dimensional structure information comprising type and coordinate values of each atom contained in the first molecule; obtaining respective van der Waals radius based on the type of respective atom contained in the first molecule, converting the three-dimensional structure information into a group of Gaussian spheres representing atoms in the first molecule; calculating overlap volume for each pair of Gaussian spheres; calculating the weight of each Gaussian sphere; calculating self-overlap volume of the first molecule, the self-overlap volume being used as a volume of the first molecule. The present invention is useful mathematical expression of molecular shape, shape comparison of drug molecules, and pharmacophore comparison of drug molecules, which comparisons, in turn, useful for virtual screening of drug molecules.
