Informatics solutions for drug discovery

Instant jchem is
Instant JChem is…

  • An “out of the box” desktop application designed for biologists and chemists

  • A fast and scalable database application for chemistry

  • A modular platform for developing future chemistry applications

Aims of instant jchem
Aims of Instant JChem

  • Provide a desktop alternative to current applications such as ISIS, Accord etc.

  • Easy to install, manage and update

  • Maintain an open modular extensible platform to allow new functionalities to be continually added (by users, ChemAxon and ChemAxon partners)

  • Integrate other ChemAxon toolkits upon demand

  • Client led development

  • Fully documented and supported

  • Localizable

Key strengths
Key strengths

  • Ease of deployment in multi user environment

  • Flexible deployment options

  • Simple and easy to use

  • Fast and scalable

  • Easy to create form and table based reports

  • Powerful search functionality

  • Powerful chemistry functionality

  • Import, export and merge capabilities

  • Modular and extensible

Database creation
Database creation

  • Create databases in seconds

  • Multiple databases can be open

  • Local and remote databases supported

    • Derby, Oracle, MySQL

  • Customize by defining additional fields

  • Support for relational data

  • Support for multiple structure table types

    • Molecule, Reaction, Query, Markush, Any Structures

For more information about database handling and search:

Import and export
Import and export

  • Flexible options for defining how to import files into the database

  • Merge data from multiple files into one dataset

  • Export wizard allows data to be exported to files

  • Standard file formats supported such as SD & RD files and Daylight smiles

  • Support for multiple encodings (e.g. Japanese text)

Calculations and predictions
Calculations and predictions

  • Add calculated or predicted properties using chemical terms fields

  • Values automatically updated when structures edited or added

  • Wide range of functions available

  • Examples:

    • logP/logD

    • pKa

    • H-bond donor/acceptors

    • Lipinski rule of 5

    • Bioavailability

    • IUPAC Name

  • Can be used as filters for searches

For more information about structure based prediction and other functions of ChemAxon’s Chemical Terms:

Chemical business rules standardizer
Chemical business rules - Standardizer

  • Control the way structures are handled

  • Nitro group representation

  • Counter-ions

  • Explicit hydrogen atoms

  • Tautomers

For more information about structure canonicalization:

Grid view
Grid View

  • A chemically aware table suitable for very large data sets

  • Multiple views can be open and visible at any one time

  • Data in the table can be sorted, queried and formatted

  • Structure changes update predicted properties dynamically

  • Various display options are possible

Form view
Form view

  • Custom forms can be designed.

  • Relational data can be displayed

  • “Snap to edges” aids form design

  • Form Widgets are bound to data fields

  • Form widgets expected to become major extension point

  • Extensible widgets and renderers

Flexible display options
Flexible display options

  • Views can be configured to format data according to users needs

  • Here options for structure display are being specified

  • Support for 2D and 3D structure display

  • Support for sub-structure highlighting and alignment to query structure

Relational data
Relational data

  • Relational data can be displayed in master-detail forms

  • Relational models can be built using the Schema and Data Tree editors

  • “Relationships” modelled on (and use) database foreign key constraints

  • Import of relational data from MDL’s RDF format files.


  • Form based query and query builder provide alternative ways of defining queries

  • Complex queries are rapidly executed even with millions of structures

  • Indexes can be added to improve performance

  • Relational and AND and OR type queries can be specified

  • Filter results with chemical terms expressions

  • Alignment and substructure highlighting in results

For more information on search features:

Query extensions
Query extensions

  • Overlap analysis

    • Compare one set of structures with another

  • Federated search

    • Run a structure search across multiple structure tables at once

List and query management
List and Query Management

  • Queries can saved and re-executed

  • Lists of results can be saved and restored

  • Queries can be restricted to a list of entries

  • List and queries can be copied or shared between users

  • Lists can be combined with Intersection, Union, XOR, A not B logic

Markush search and enumeration
Markush search and enumeration

  • Markush table type for storing Markush structures

    • Combinatorial libraries

    • Patents

  • Perform structure searches against the Markush structures

  • Enumerate a Markush structure

    • Full enumeration

    • Random enumeration

    • Enumerate within context of a query structure


1. Traditional installer

  • Updated modules can be downloaded and installed

  • Allows you to keep up to date with the latest features and fixes

  • Customers can configure their own update center

  • Distribute your own plugins

    2. Java Web Start

  • Zero install option

  • Deployable at customer’s site

Multi user environments
Multi-user environments

  • Pre-configured settings for multi-user environments

    • Centralised deployment through Java Web Start

    • Centralised project and connection configuration

    • Centralised license management

  • Multi-user databases

    • Access control

    • Sharing of views, queries, lists

  • ‘IJC URLs’: click on a hyperlink in web/email and:

    • IJC opens (installing if necessary)

    • Open the specified view

    • Apply the specified query or list


  • ‘Personal’ (no license required)

    • Free for commercial and academic users

    • Local databases only - no search limitations

    • Default standardization included (custom standardization requires standardizer license)

    • Most chemical terms functions require calculator plug-in licenses

    • Markush features need licenses

  • ‘Enterprise’ (requires license)

    • Shared databases (Oracle and MySQL)
