About ChemAxon Products

Marvin Applets and Marvin Beans

Marvin is a collection of Java tools containing MarvinSketch, MarvinView and MarvinSpace for drawing and visualising chemical structures, queries and reactions.

Calculator Plugins

Calculator Plugins are a range of structure based prediction tools.
Single or small numbers of structures can be processed from the Tools menu of MarvinSketch and MarvinView. For batch processing they can be called from command line (via cxcalc), ChemAxon's Chemical Terms language and from the API.

JChem Base

JChem Base is a tool for the development of applications that allow for the search of mixed structural and non-structural data.
JChem Base will integrate with a variety of database systems (Oracle, MS SQL Server, DB2, Access, etc) with web interfaces and offers fast substructure, similarity, exact and superstructure search engine using 2D hashed fingerprints.

JChem Cartridge

JChem Cartridge adds chemical knowledge to the Oracle platform.
Data can be searched by structure, substructure and similarity criteria through extending Oracle's native SQL language. Chemical data can be easily inserted and modified using SQL.

Instant JChem

Instant JChem is a desktop application for scientists to manage chemical and non chemical information on local and remote databases.
Based on ChemAxon's JChem and Marvin, Instant JChem lets users easily create chemical databases, import and export structure files and view, search, sort, analyse and edit contents.

Standardizer

Standardizer is a structure canonicalization tool in JChem for converting molecules from different sources into standard representational forms. Standardizer can automate the identification of mesomers and tautomers and can be used for counter-ion removal.

Reactor

Reactor is the virtual reaction engine of Chemaxon's JChem technology. It supports "smart" reactions (generic reaction equations combined with reaction rules) generating chemically feasible products even in batch mode. The professional version of the tool includes support for multi-step virtual synthesis and filtering of chemically feasible molecules which are not of interest.

JKlustor

JKlustor is a tool of JChem for clustering, diversity calculations, and library comparisons based on molecular fingerprints and other descriptors. JKlustor is useful in combinatorial chemistry, drug design, or other areas where a large number of compounds need to be analyzed.

Screen

Screen is a comprehensive HTS suite in JChem, which works with files and structure databases and features various models for the similarity analysis of molecules and pharmacophore hypotheses.

Fragmenter

Fragmenter uses RECAP and other methods to create building blocks by fragmenting larger molecules. Fragmenter is particularly relevant for generating analogues of biologically active compounds for lead discovery and for decomposing compounds to identify central structures.
