Accelrys Announces MS Modeling 3.0

San Deigo, CA, September 8 2003

Accelrys, a wholly owned subsidiary of Pharmacopeia, Inc. (NASDAQ: PCOP), today announced the latest release of MS Modeling, the Materials Studio(R) modeling and simulation software suite for researchers in the chemicals and materials industries.

MS Modeling 3.0 features new tools for materials property prediction using statistical correlation methods and for crystallization modeling. QSAR provides quantitative structure activity relationships, statistical methods that identify patterns in existing data sets that are then used to predict a multitude of materials properties. Polymorph Predictor and X-Cell are novel computational methods that enable the prediction of crystal structure. This information is critical for scientists studying crystalline products such as drugs, pigments, and specialty chemicals.

MS Modeling is used in industries such as chemicals, petrochemicals, polymers and rubbers, cosmetics, and home and personal care. It is also used in the analysis of products and processes from nanotechnology to bulk chemical production. MS Modeling 3.0 tools also address challenges in both commercial and academic R&D such as reducing lead-times, increasing understanding, and screening candidate materials. The client-server architecture of MS Modeling 3.0 enables researchers to create scenarios on Windows(R)-based PCs, perform those calculations on dedicated server machines, and then view the results back on the PC. This architecture enables collaboration, making it easy to readily share this information with colleagues.

“MS Modeling 3.0 represents a significant milestone in the deployment of modeling products on the desktop,” said Dr. Scott Kahn, chief science officer, Accelrys. “For the first time researchers will be able to integrate modeling results with statistical correlations on a standard PC, opening the door to the analysis and prediction of essentially any material property.”

About the Materials Studio Family

The Materials Studio family is a software environment that brings the world’s most advanced materials simulation and informatics technology to the desktop PC. It enhances the ability to mine, analyze, present, and communicate data and information relating to chemicals and materials. The Materials Studio suite’s accurate prediction and representation of materials structure, properties, and inter-relationships provide valuable insight. Its tools solve key problems throughout the R&D process, capturing and helping organizations to share critical knowledge.

Successes using the Materials Studio family have been reported in industries including chemicals, plastics, pharmaceuticals, paints, electronics, and aerospace. MS Modeling, Materials Studio’s modeling and simulation environment, is designed for structural and computational researchers in chemicals and materials research and development who need to perform expert-level modeling and simulation tasks in an easy-to-learn yet powerful environment.
