Chemical Library Enumeration. Chemical Library Enumeration (This workflow can be found on the KNIME Workflow Public Server under 050_Applications/050001_ChemicalLibraryEnumeration Note that this workflow requires the installation of various nodes from the community update site!)
The Workflow The workflow demonstrates how a chemist could create a virtual library of Amides based on a set of Acids and Amines.For the enumerated products, some molecular properties are then calculated and the products are filtered based on the Lipinski "rule of 5". In order to demonstrate the interoperability of the different community contributions, the workflow uses nodes from the RDKit, CDK, and Indigo integration. In practice, this is, of course, not absolutely necessary. The Report The workflow uses a QuickForm to allow the user to select the type of plot to accompany a report combining numeric, text and image data along with the selected graph in a summarized report: Sharing Metanodes Deploying the workflow using the KNIME WebPortal.

Online chemical modeling environment (OCHEM): web platform for data storage, model development and publishing of chemical information. Chemistry Freeware. On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet.
All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. ACD/ChemSketch 12 Freeware. ACD continues to release updates to the outstanding Chemsketch freeware. Accelrys Draw is a program that allows you to generate structural formulas for complex molecules using a very intuitive drag-and-drop interface. No-fee Accelrys JDraw for academic and non-commercial use. Discovery Studio Visualizer 4. ChemAxon produces a wide range of Java-based chemistry tools, and they offer free academic licenses (you must register with them). Jmol is a free, open source molecule viewer for students, educators, and researchers in chemistry and biochemistry. EniG. Virtual Laboratory Software. LogP Calculator.

PubChem Download Page. This file contains the structures downloaded from the PubChem FTP site that have at least one assay result associated with them that was obtained in the context of the NIH Common Fund (previously: NIH Roadmap) Molecular Libraries Probe Production Centers Network (previously: Molecular Libraries Screening Center Network), part of the Common Fund’s Molecular Libraries and Imaging program .
It is organized by unique chemical structures (“Compounds” in PubChem parlance), i.e. assay results for possibly multiple different samples (“Substances” in PubChem parlance) have been combined into the one record representing the unique chemical structure. Placeholder assays (assays containing a single record only) have been filtered out. Explanation of the property data fields in the SD file (note - properties present in the original PubChem files have been copied unchanged, for the explanation of those properties we point directly to the appropriate PubChem document ): Igor Filippov.
