MDL Chime

MDL Chime lets scientists view chemical structures from within popular Web browsers, Java Applets, and Java applications, and is used as part of DIADEM to display 3D models of compounds in the database that can be rotated and manipulated.

Chime will be of special interest to organic chemists engaged in pharmaceutical, agrochemical, and biotechnology R&D, in industry and academia. It is a particularly valuable tool for scientists specializing in cheminformatics.

Using Chime, researchers can easily add structures to their projects, tutorials, newsletters, journals, and presentations published across an intranet or the Internet. With knowledge of Rasmol or CSML scripting, you can even create interactive Web pages.

Chime is a browser plug-in that renders 2D and 3D molecules directly within a Web page. The molecules are "live", meaning they are not just static pictures, but chemical structures that scientists can rotate, reformat, and save in various file formats for use in modeling or database applications.
