BURLINGAME, Calif., April 9, 2021 /PRNewswire/ — Collaborative Drug Discovery, provider of CDD Vault web-based drug discovery informatics platform, announced they won a competitive, peer-reviewed Phase 2 SBIR grant from NIH NCATS, titled: “Intelligent Chemical Structure Browser for Drug Discovery and Optimization”. This is a continuation of the Phase 1 project announced in 2019.

Collaborative Drug Discovery, Inc. (CDD) has developed a novel intelligent data browser that will enable medicinal chemists developing new drug compounds to more efficiently browse and organize experimental data in an intuitive way that — for the first time — matches how they mentally map the relationships among the closely similar molecules that comprise a chemical lead series.

We estimate that our innovative approach will scale to thousands, and ultimately millions, of compounds in just a few minutes (on the same hardware), enabling us to create a delightful user experience that will present intuitive, automated chemical hyperlinking while hiding the internal complexity. The technology will also enable new types of sophisticated, automated structure–activity relationship (SAR) analyses of lead series data, such as generalized forms of Free-Wilson analysis and automated suggestions of which missing experimental data would best strengthen the understanding of the SAR. In Phase 1, we developed a lattice representation and associated algorithms and demonstrated that they scalably support all the operations needed to realize the vision of the software. In Phase 2, we will build the complete application, develop further analysis methods, and test it with external partners.

Navigating through and extending a lead series to discover the optimal drug candidate to advance into animal studies and clinical trials comprises a critical stage of the drug discovery pipeline: the success of large subsequent investments depends on making the right decision. This stage also especially emphasizes creative and intuitive thinking. Existing software that assists scientists engaged in this task tabulates data in formats that make it difficult to assemble and compare the essential data needed to rapidly explore ideas about how to further optimize promising candidates. Our proposed intelligent browser represents a highly innovative solution that will essentially “hyperlink” chemical space. It will allow chemists to navigate easily among compounds following the same pathways that lead from one compound to the next in the mental models that they intuitively map in their heads, and to instantly create compact tables containing just the right experimental data to answer the questions that emerge from exploring any particular pathway.

“These capabilities in turn will enable medicinal chemists to make better decisions about which new compounds to synthesize and submit for expensive assay assessment,” said Peter Gedeck, PhD, Senior Research Scientist at CDD, “Since it is feasible to test only a limited number of compounds, better scientific decisions at this stage can significantly increase the chances that a drug candidate will successfully emerge through the clinical pipeline as an approved drug that is safer and more effective.”

“CDD will remain the best in the world and differentiated for chemistry drug discovery data, even as we turn our eye to the large needs for superior tools for biological drug discovery data,” said Barry Bunin, PhD, CEO of CDD.
