Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other...

In the regulatory assessment of chemicals (e.g. under REACH), Quantitative Structure Activity Models (QSAR) are playing an increasingly important role in predicting properties for hazard and risk assessment. This implies both a need to be able to identify relevant QSARs and to use them to derive estimates and/or have access to their precalculated estimates. To help meet these needs, the JRC QSAR Model Database is established and freely accessible through http://qsardb.jrc.ec.europa.eu/qmrf The QSAR Model Reporting Format (QMRF) is a harmonised template for summarising and reporting key information on QSAR models, including the results of any validation studies. ...

JSmol is the extension of the Java-based molecular visualization applet Jmol (jmol.sourceforge.net) as an HTML5 JavaScript-only web app. It can be used in conjunction with the Java applet to provide an alternative to Java when the platform does not support that (iPhone/iPad) or does not support applets (Android). Used in conjunction with the Jmol JavaScript Object (http://wiki.jmol.org/index.php/Jmol_Javascript_Object), JSmol seamlessly offers alternatives to Java on these non-Applet...

Scaffold Hunter is a JAVA-based software tool for the analysis of structure-related biochemical data. It enables generation of and navigation in a scaffold tree hierarchy annotated with various data.

Platform independent (written in Java), with the use of The Chemistry Development Kit.

VMS Draw provides general utilities (e.g. normalization, conversion, and other manipulations of several spectra at the same time) and a flexible graphical user interface (GUI) for an easy use by non-specialists which allows a seamless flow of information between experimentally and theoretically oriented researchers. Finally, it permits effective interactions with other electronic structure codes [e.g., nuclear magnetic resonance (NMR), microwave] even if Gaussian 16 offers the widest set of methods for computational spectroscopy.

Computationally predicts the pharmacokinetic properties of drug candidates using Quantitative Structure Property Relationships (QSPR) modelling. Assembles a set of tools and databases for predicting the physical properties of small molecules. The program models a given property's dependence on a collection of molecular and structural descriptors using a training set of molecules. Neural networks and support vector regression are available, as well as linear models.

Chemical structure sketching tool, for use with various cheminformatics applications. Convenient to use and moderately sophisticated. Suitable for viewing, creating and editing MDL MOL files.

The Avalon Cheminformatics Toolkit contains tools to render and canonicalize SMILES and manipulate MOL file and related formats as well as structure fingerprinting.

This project is an interactive viewer for 3D virtual screening data.

Predyketide is a stand-alone desktop application which provides a way to observe the resulting structure per elongation of the polyketide chain, and predict the most possible natural product structure. This tool can be helpful in the discovery of new drugs requiring lesser time and effort. The project uses the cdk v.1.5 and cdk-jchempaint-26.

Protein Data Bank transformed into an SQL database with a very powerful search engine and a rich web interface. The engine combines chemical, sequence and 3D structure searches. The interface provides statistics, sequence and 3D structure alignments.

QSAR is a project that aims to build a GUI that enables people to build quantitative structure activity (or property) relationship models. It will use parts of CDK (cdk.sf.net), JOELib (joelib.sf.net), R (www.r-project.org) and other projects.

MCDL is a small Java molecular viewer/editor for chemical structures, stored in Modular Chemical Descriptor Language linear notation. Features include accurate structure diagram generation, and Kekule chemical structure creation from aromatic bond list.

Chemical Evaluation Framework (CEF) is a molecular structure based software to assist in hazard assessment. Download requires Java 6 update 1. Source code is contained in jar files. Download contains GSH reactivity plugin.

Structure is a framework for two-dimensional molecular visualization written in Java and based on Octet.

2-D chemical structure drawing program

The RNA Ontology Consortium proposed a translation the RNA backbone angles to 46 clusters ('suites') and hence unique names. This project calculates the suites from RNA 3D structures, and to search on a Java-based index structure of known folds.
