SOMA2 – Drug Design Environment Drug design environment – SOMA2 The SOMA2 project 2002-2006 • • • • • • Tekes (National Technology Agency of Finland) DRUG2000 program. Organizes and updates CSC’s (the Finnish IT Center for Science) modeling program environment to meet the standards in modern computer-aided molecular design. Promotes the use of computing tools in drug discovery research work in Finland. Provides easy access to computational tools through WWW – interface. Integrates different tools, operates as middleware program. Allows user to define unique computational workflow (pipeline, network etc.). Drug design environment – SOMA2 O H H H O H FROM MOLECULES … … TO PROTEINS … …AND CELL-LEVEL ACTIVITIES Software for ADME and structure-based drug discovery • • • • • • Databases of chemistry and protein structures and tools to analyze them Docking and classification of molecules QSAR (Quantitative Structural Analysis Research) Computer-assisted high-throughput screening Design of ligands ADME predictions (Absorption, Distribution, Metabolism and Excretion), Toxicity Data management, data mining and visualization Drug design environment – SOMA2 INTERNET, researcher’s PC a) CSC-network and Scientist interface, SOMA2 environment computing grid Basic technical concept • Dock to target protein Convert to 3D Calculate chemical properties Query database GOLD on Linux Corina on Solaris Sybyl on Linux ISIS on Solaris WWW – interface is based on the XML – description of a program. O b) INPUT: • Different machine architectures are hidden. • Automatic generation of program and platform specific configuration files. 2D structure, known data O SOMA2 environment O CML O • CML (chemical markup language) is used as internal data format (data transferred in XML). ADME prediction • XML 2D > 3D conversion XML Unique computational workflows. OUTPUT: O O • 2D structure, • 3D structure, • original data, • docking score, • ADME-values Docking XML Drug design environment – SOMA2 Model workflow Figure from: Lehtovuori, P. Nyrönen, T., SOMA - Workflow for Small Molecule Property Calculations on a Multiplatform Computing Grid, J. Chem. Inf. Model., 2006, 46(2), 620-625. Drug design environment – SOMA2 Generic user interface generation • • • User interface generated from description that is based on XML schema (“template”). No programming skills required to produce XML – description of a program. • New programs are easily added to SOMA2 – environment. Save expert user knowledge in XML. Flexibility • • Not only for cheminformatics and drug design. SOMA2 – system can be applied in almost every application area. Open source thinking • • Similar products available usually they are commercial. Although some of the programs used are commercial, SOMA2 system is planned to be open source. Drug design environment – SOMA2 Model workflows • User can choose a predefined workflow for specific task. • Predefined workflow can still be freely modified. • Possibility to save own workflows as a template. Drug design environment – SOMA2 Input molecules • Upload files from local computer. • Sketch molecules within the user interface. Drug design environment – SOMA2 Database query • MDL ISIS host databases. • Support for structure search. • Search results imported to SOMA2 – system or downloaded. Drug design environment – SOMA2 Program configuration • Easy configuration of programs. • Useful help texts and reasonable defaults included in program XML. • System includes model templates for running a program. Drug design environment – SOMA2 Workflow manager • Free navigation between steps. • Insert, change and delete operation supported. Drug design environment – SOMA2 Result view • Spreadsheet like result view. • Tools for sorting and filtering data. • Basic data analysis. • Save molecular data in different formats. Drug design environment – SOMA2 Result details • Visualisation of the result molecules. • Summary of computed properties.
