MOARF, an Integrated Workflow for Multiobjective Optimization: Implementation, Synthesis, and Biological Evaluation.
MetadataShow full item record
We describe the development and application of an integrated, multiobjective optimization workflow (MOARF) for directed medicinal chemistry design. This workflow couples a rule-based molecular fragmentation scheme (SynDiR) with a pharmacophore fingerprint-based fragment replacement algorithm (RATS) to broaden the scope of reconnection options considered in the generation of potential solution structures. Solutions are ranked by a multiobjective scoring algorithm comprising ligand-based (shape similarity) biochemical activity predictions as well as physicochemical property calculations. Application of this iterative workflow to optimization of the CDK2 inhibitor Seliciclib (CYC202, R-roscovitine) generated solution molecules in desired physicochemical property space. Synthesis and experimental evaluation of optimal solution molecules demonstrates CDK2 biochemical activity and improved human metabolic stability.
