1 2008 Accelrys EUGM Pipelining ChemAxon Szilard Dorant Solutions for Cheminformatics

2 2008 Accelrys EUGM The Component Collection: Quick facts Provides access to ChemAxon tools from Pipeline Pilot Free of charge Open source : Java sources are also included Available from ChemAxon or Accelrys Latest version : 1.4 –Released in November 2008 –Requires JChem / Marvin 5.0.1 or better –Tested against Pipeline Pilot 6.1.1

3 2008 Accelrys EUGM Whats new in 2008* Direct support and development from ChemAxon 3 major releases – one about every 4 months 6 early access releases 12 new user components Several components significantly upgraded VersionDate 1.2March 5 1.3July 11 1.3.1October 22 1.4November 24 User interestDevelopment *As of November 2008

4 2008 Accelrys EUGM Available functionality Standardizer: structure canonicalization Chemical Terms expressions for filtering and calculations (including logP, logD, pKa, HBD, HBA, Isoelectric point, PSA and more) Reactor: smart virtual reaction processing Maximum Common Substructure (MCS) based clustering IUPAC Name Molecule conversion (both directions) JChem chemical database: insertion, search and retrieval of structures; create and drop structure tables Marvin applets: structure visualization and editing Major microspecies (major protonation form) Microspecies distribution Burden eigenvalue descriptor (BCUT)

5 2008 Accelrys EUGM Chemical Terms Calculator Use arbitrary Chemical Terms expressions Results stored to arbitrary properties A wide range of ChemAxon functionality can be accessed as Chemical Terms functions New in 1.3

6 2008 Accelrys EUGM Canonicalization with Standardizer Simple to use, but now full complexity is also available: Simple actions (checkboxes) Configuration string (simple or XML) Configuration file Upgraded in 1.2

7 2008 Accelrys EUGM IUPAC naming components IUPAC Name to Molecule Molecule to IUPAC Name Example roundtrip protocol: New in 1.4

8 2008 Accelrys EUGM Reactor Improvements: Upgraded in 1.4 Synthesis code generation Output reaction mapping Advanced options: –Unambiguous only –Ignore rules: Reactivity and Exclude Selectivity Tolerance

9 2008 Accelrys EUGM Combinatorial Reactor Example

10 2008 Accelrys EUGM Clustering with LibMCS Maximum Common Substructure (MCS) based clustering Size of smallest common substructure to consider Three levels of heuristics: –Exact (no heuristics) –Fast –Very Fast Bond type, atom type, charge can optionally be ignored Disallow breaking rings (default) Options: New in 1.4

11 2008 Accelrys EUGM JChem Base Insert Returns cd_id (primary key) values Two input modes: –read structure source from a specified property –if property not specified uses PP input molecule Insert into additional data fields* New features: *Under development, currently limited to string database column types Duplicate filtering option (using Pass and Fail ports) Upgraded in 1.2

12 2008 Accelrys EUGM Several search options were added Easier protocol integration and better performance due to concentrated functionality JChem Database Search Upgraded in 1.2

13 2008 Accelrys EUGM JChem Base demo protocol

14 2008 Accelrys EUGM Improved error reporting Helps to track down problems quicker More information is displayed in the error dialog: Marvin or JChem version, the current structure, etc. Utility component for displaying ChemAxon environment (from 1.4) If the environment variable CHEMAXON_PP_LOG_DIR is set, an even more detailed error report will be appended to the file "pp_error.txt" in the specified directory New in 1.3

15 2008 Accelrys EUGM Planned components JChem Cartridge for Oracle Integration with Instant JChem Tautomer generation Conformer generation Conversion of various structure file formats Node release cycle is fast and flexible. Please advise us on priority and additional functionality for future node development.
