Molecular Electrostatic Potential as a Graph
Édgar E. Daza, Julio R. Maza, Raul Torres · Current Computer - Aided Drug Design · 2013
We present several procedures to represent molecular electrostatic potential as a graph, based on the pattern of critical points and their neighborhood relations. This representation is used for the molecular electrostatic comparison, which is reduced to a comparison of tree-type graphs. Several methods to compare trees are also presented. The applications of this algorithm to compare and classify molecules through their electrostatic potential are illustrated. Keywords: Scalar fields, graphs, rooted trees, similarity measures, molecular comparison, chemical similarity.
