Solutions for Cheminformatics
What is new since last year?
Changed the way structures are handled
• Major improvements in performance
• Handle any number of structures
• Structures move and resize (changing their
aspect) with cells
• Structure delete undo
• Unique feature: Structure edit undo
Features
• Easy handling of structures inside Excel
• Import from Databases
• Import from, and export to files
• Structure Filtering
• R-Group Decomposition
• Custom chemical Excel functions
Structure Handling
“Live” structures in Excel
• Add, edit on double click with
• Marvin Applet or Marvin Beans
Excel operations
• Cut, copy paste between worksheets
• Move, resize
• Undo, redo
• Filter structures
• Hide structures
Import from Database - Sources
Manage connections for all data sources in a single place.
New: MySQL support
• JChem Cartridge Databases
• Search runs on the server
• JChem Base Databases
• Search runs locally
• Oracle, MySQL
Import from Database - Query
Search for structures using all JChem’s query features.
New: Selectable search method, target column
• Easy to use control for
specifying search options
• Chemical Terms filter
expressions for queries
• Optional substructure hit
coloring
• Additional SQL filters
Import from Files - Export to Files
Import from popular file formats: SDF, RDF, SMILES,MRV
and list of IUPAC names
New: Pick structure column to export
• Wizards guide you through the
import and export processes
• Pick the properties to import or
export
R-Group Decomposition
Find a central structure - scaffold - and identify its ligands at
certain attachment positions.
New: Coloring
• Run decomposition on Files
and worksheets
• List all possible decompositions
• Query modifications
• Various attachment symbols
Custom chemical Excel functions
• Values are calculated
from:
– SMILES, IUPAC
Name strings
– Structure cell –
structures resulting
from imports, edit, or
other function
• Function results are
automatically updated
when structures edited or
added
• Multi thread calculation in
Excel 2007
Custom chemical Excel functions
Most Chemical Terms functions and Marvin calculations are
implemented as Excel functions
• Composition,Mass,
MolFormula…
• AtomCount,BondCount,ChiralC
enterCount,RingCount…
• logP,logD, pKa, PSA, H-bond
donor/acceptors
• Bioavailability,
GhoseFilter,LeadLikeness,Lipin
ski rule of 5…
• SubstructureMatch,
Dissimilarity
• IUPAC Name
Future Developments
• Improve copy-paste from to external applications
• Structure display settings
• Improve import append mode with column mapping
• Preview data in grid, before placing in Excel
• Load and save queries
• Hierarchical AND / OR criterias
• Relational data handling, with outlines, task panes.
• Web Services: JChem, PubChem, ChemSpider
• Form (template) based display in Excel
• Reactor, Standardizer..
