Title:
METHOD AND APPARATUS FOR DERIVING NEW DRUG CANDIDATE SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2021/071000
Kind Code:
A1
Abstract:
A method for deriving a new drug candidate substance by means of a computing device may be disclosed. The method for deriving a new drug candidate substance comprises the steps of: creating a refined knowledge network in which nodes representing respective biological entities are connected using connection lines representing correlations between the nodes; analyzing drug-disease node pairs present in the refined knowledge network to determine a basic drug for deriving a new drug candidate substance; and using an artificial neural network-based structure prediction model to acquire an analogous substance having a chemical structure similar to that of the basic drug, wherein the biological entities include at least one among genes, proteins, metabolites, symptoms, diseases, compounds, and drugs, and a simplified molecular-input line-entry system (SMILES)-based character string of the basic drug may be input to the structure prediction model.
