San Leandro and Santa Clara, CA, May 2, 2006 - Symyx Technologies, Inc. (Nasdaq: SMMX) has joined the rapidly expanding MDL® Isentris® Alliance, a wide-ranging community of informatics companies working with Elsevier MDL to offer researchers in pharmaceutical, biotechnology and other life sciences industries more effective, better integrated solutions to manage challenging R&D workflows.

Collaborative efforts under the MDL Isentris Alliance are particularly important to research organizations and pharmaceutical companies that rely on multiple, specialized R&D software tools. The ability to coordinate information flow between varieties of complex lab information systems is essential to effective, timely decision making.

“We’re pleased that our partnership with Elsevier MDL will offer researchers more options for assembling informatics systems that utilize common, open technology platforms,” said David Dorsett, General Manager of Symyx Software. “The integration of the Symyx Software platform with the Isentris platform will be a welcome advantage to common customers and the research community.”

Elsevier MDL Senior Vice President, Framework Development, Vikki Rehn, said: “The effective integration of research data and workflow applications offers R&D organizations a path to improved productivity. As major pharmaceutical research organizations move beyond industry-standard MDL ISIS technology to adopt the new-generation MDL Isentris platform, collaboration between leading informatics suppliers under the MDL Isentris Alliance enables rapid integration of specialty applications into a comprehensive research information system.”

Symyx joins a group of leading software and consulting companies from around the world (including Spotfire, Tripos, InfoChem, InforSense, Klee, Aston and DeltaSoft) working with Elsevier MDL to create specialized informatics solutions that combine MDL Isentris technology and offerings from different vendors to improve life science research productivity and return on R&D investment.
