A Knowledge Based Approach to Drug Repurposing for Socially Important and Rare Diseases.
RSF - DST Project # 16-45-02012 - INT/RUS/RSF/12

The Project

The purpose of this project is to develop a computational platform designed for efficient analysis and interpretation of the extensive biomedical and clinical data, the comparative analysis extracted from these data information to differentiate the normal and pathological states, obtaining new knowledge to identify biomarkers and pharmacological targets, designing potential drugs with the required properties, determine the optimal approach to therapy taking into account the individuality of patients. The project will be carried out by analyzing existing data sources and selecting the most promising information and computational resources; if necessary, available methods will be improved, and new methods will be created; an approach to their integration into a single platform will be developed and implemented (see: General Flowchart).

Validation of the developed computational platform will be carried out on the case studies of common and rare socially important diseases with non-infectious nature (diabetes, cancer, CNS disorders) and infectious diseases (tuberculosis, leishmaniasis, schistosomiasis), which will determine the optimal scenario for its use and, if necessary, to conduct an appropriate upgrade.

Special emphasis will be placed on the repositioning of known drugs (identifying new indications for known pharmaceuticals), which allows in many cases to carry out an accelerated testing of computer-aided predictions directly in the clinic and even a direct introduction of such drugs into medical practice ("off-label prescription"). Informatics based approaches with the data available from the physicians will be employed for the identification of optimal FDA approved drugs for their new pharmacological effects.

General Flowchart


Center for Molecular Modeling of the CSIR-Institute of Chemical Technology headed by Prof. Narahari Sastry for a number of years engaged in the development and practical application of computer-aided drug design methods, including structure-based approaches, pharmacophore modeling, virtual screening, etc. They designed new pharmacological agents acting on different pharmacological targets, using a wide range of molecular modeling techniques, such as molecular dynamics, docking, homology modeling, QSAR and informatics methods. Indian team created the Molecular Property Diagnostic Suite (MPDS) on the basis of Galaxy platform. The main aim of MPDS is to assess and estimate the drug-likeliness of a particular compound in order to estimate its potential applicability as a drug. MPDS is a common platform to merge many available open-source as well as in-house in silico tools to support open source drug discovery programs by prioritizing compounds before taking to synthesis.

Indian team made a number of predictions about the properties of synthetic accessibility and properties of organic molecules. A large part of computational predictions was confirmed experimentally (PLoS ONE., 2015, 10: e0144294, J. Phys. Chem. C., 2015, 119: 23607–23618, J. Chem. Inf. Model., 2015, 55: 848-860, J. Comp. Chem., 2015, 36: 529-538, PLoSONE, 2014, 9: e113773, Acc. Chem. Res., 2014, 47: 2574-2581, J. Comp. Chem., 2014, 35: 595-610, Curr. Pharm. Des., 2013, 19: 4714-4738, Chem. Rev., 2013, 113: 2100-2138, J. Chem. Inf. Model., 2011, 51: 558-571).

Laboratory for Structure-Function Based Drug Design headed by Prof. Vladimir Poroikov during the past twenty years develops computational methods, programs and databases for identification of promising pharmacological targets and finding their ligands. An original system of atom-centric molecular descriptors characterized the intermolecular protein-ligand interactions is developed, and used as the basis to perform analysis of various structure-property relationships. (J. Chem. Inf. Comput. Sci., 1999, 39: 666–670; SAR & QSAR Environ. Res., 2009, 20: 679-709; J. Chem. Inf. Model., 2014, 54: 498–507). Russian team created computer programs for prediction on the basis of structural formula of drug-like organic compounds: biological activity spectra (Chem. Heterocycl. Comp., 2014, 50: 444-457); gene expression (Bioinformatics, 2013, 29: 2062-2063); acute toxicity to rats at four routes of administration (Mol. Inform., 2011, 30: 241–250); interaction with undesired targets (Chem. Res. Toxicol., 2012, 25: 2378-2385), interaction with biological targets (SAR & QSAR Environ. Res., 2015, 26: 783-793); interaction with non-tumor and tumor cell lines (SAR & QSAR Environ. Res., 2015, 26: 595-604); interaction with metabolic enzymes (J. Chemoinform., 2016, 8: 68).

Based on the created computational tools, Russian team developed a number of predictive web-services at the Way2Drug platform that are used by many researchers worldwide. The synergistic association of mutually complementary knowledge, experience and skills of multidisciplinary teams of Russia and India in the framework of this project will allow achieving the results that none of the teams could be achieve working separately.

The project will lead to overcome the interdisciplinary barriers between the biomedical and clinical disciplines by creating dynamic data-processing environment for the interaction of diverse specialists that will lead to a significant increase in the efficiency of the use of the extensive biomedical and clinical data in medical practice, and lay the foundation for long-term cooperation between Indian and Russian scientists in the area of discovery, development and application of novel more effective and safe medicines.


The project is supported by the Russian Science Foundation (grant No. 16-45-02012) and Indian Department of Science and Technology (grant No. INT/RUS/RSF/12).

On June 15-22, 2017, five members of Indian team, including Drs. Garikapati Narahari Sastry, Rajesh Kumar Goel, Rakesh Sahay, Manisha Sahay and Mr. Sandeep Kumar, have visited the Russian collaborators at the Institute of Biomedical Chemistry, Moscow, Russia.

On October 29th – November 4th, 2016 three participants of Russian team, Prof. Vladimir Poroikov, Dr. Anastassia Rudik and Dr. Dmitry Druzhilovskiy, have visited the Indian collaborators at the CSIR-Institute of Chemical Technology (CSIR-IICT) in Hyderabad, India. During this visit Russian and Indian participants of the project discussed the general architecture of the computational platform and protocols of the informational exchange, and also performed some joint computational experiments to validate the computational facilities of Indian and Russian teams.

In joint computational experiments we evaluated the possibility of application of molecular modeling methods by their retrospective validation on a specially prepared test sample, comprising 18 structural formulas of novel anti-TB compounds. Using PASS program, Russian team showed that the existing version of the PASS successfully predicts antituberculosic activity for 11 of the 18 compounds. Molecular docking conducted by the Indian colleagues showed that 17 of 18 compounds of the appraised value of the binding energy function (scoring function) are superior to those of the reference compounds 2,6-pyridinedicarboxylic acid. Thus, the combination of computer predicting methods, based on the structure of the ligand, developed by the Russian participants of the project, with the methods of molecular modeling, prepared by the Indian participants of the project, allows improving the quality of the assessments.

We also discussed with medical doctors from Osmania General Hospital and Osmania Medical College, Prof. Rakesh Kumar Sahay (Department of Endocrinology) and Prof. Manisha Sahay, (Department of Nephrology), the possibilities of utilization of available clinical data on pleiotropic action caused the therapeutic and adverse effects of the approved human medicines.
