Abstract: Disclosed herein is a method of generating a 3D conformation of a molecule used in in-silico drug discovery. The method includes obtaining a 2D graph of the molecule. A first tensor including molecular graph information and a second tensor including graph, coordinate and distance information of atoms of the molecule are generated.

Abstract: Disclosed herein is an automated small molecule generation process for use in in silico drug discovery. The automated process employs a trained neural network that analyzes a graph adjacency tensor which represents a small molecule compound. Over subsequent iterations, the trained neural network analyzes the graph adjacency tensor and predicts actions (e.g., adding an atom, adding a bond type, or assigning a charge) that, if taken, are likely to lead to a valid small molecule compound. Thus, the methods described herein generate small molecule compounds of increased validity in comparison to conventional methodologies.
