It features an evolutionary algorithm that automatically designs novel ligands with drug-like properties and synthetic feasibility using click chemistry. Isyn interfaces with our popular and fast molecular docking engine idock, remarkably reducing the evaluation and ranking time of drug candidates. Furthermore, inspired by our user friendly and high-performance WebGL visualizer iview, our iSyn also implements a tailor-made interactive visualizer to aid novel drug design. We believe iSyn can supplement the efforts of medicinal chemists in drug discovery research. To illustrate the utility of iSyn in generating novelligands ex nihilo, we designed predicted inhibitors of two important drug targets, which are RNA editing ligase 1(REL1) from T. Brucei, the etiological agent of African sleeping sickness, and cyclin-dependent kinase 2 (CDK2), a positive regulator of eukaryotic cell cycle progression. Results show that iSyn managed to significantly enhance the predicted binding affinity of the best generated ligand by more than 3 orders of magnitude in potency. Isyn is written in C++, Python, HTML5 and JavaScript. It is free and open source, available athttp://istar.cse.cuhk.edu.hk/iSyn.tgz. It has been tested successfully on both Linux and Windows.enInteractiveDrug DesignDrug DiscoveryUser-FriendlyCyclin-Dependent KinaseEvolutionary AlgorithmsMedicinal ChemistryClick ChemistryTrypanosoma BruceiDrug-Like PropertiesImportant Drug TargetDrug Discovery ResearchEx NihiloCarboxylic AcidOxygen AtomsHuman-Computer InteractionCyclin-Dependent Kinase InhibitorSolvent Accessible Surface AreaAcid AnhydrideRefactoringInitial LigandFragment LibraryHardware AcceleratorsProtein-Ligand DockingInput FieldMolecular SurfaceConference Paper10.1109/IV.2014.10
