Barcelona, September 21, 2007 - Prous Science is pleased to announce a new release of Integrity^®, the world's first integrated drug discovery and development portal. This new release offers a number of technology and content enhancements as part of Prous Science's ongoing mission to empower knowledge-based drug discovery and development.

Three new Knowledge Areas have been added to the existing ones in Integrity^®, extending its reach within the scientific community:

** Biomarkers Knowledge Area, covering indicators of normal biological or pathogenic processes that can be objectively measured and evaluated.
** Targets & Pathways Knowledge Area, highlighting target-based approaches to disease diagnosis and therapeutic intervention.
** Genomics Knowledge Area, establishing the foundation that will lead from gene to disease.

Further enhancements in this release -- now available to users worldwide - include enhancements to the Advanced Search functions and new search and display fields, including Product Categories, to facilitate the retrieval of information on biologics, drug delivery systems, devices and combination products; Administration Route; Formulation; and Prescription/Indication type, covering nutraceuticals, orphan drugs and compounds with pediatric indications.

Chemists will benefit from the new structure editor options in the Organic Synthesis Knowledge Area. Users can now choose between MDL^® Draw; MDL^® ISIS/Draw + MDL^® Chime; CambridgeSoft CS ChemDraw^® Plugin; and ChemAxon Marvin Applet for their searches.

The new Integrity Reports feature will allow users to generate reports that combine information from across Integrity® Knowledge Areas.

Forged by insight from almost 50 years of biomedical content development, Integrity^® takes knowledge management for the pharmaceutical professional one step further. By anticipating trends in drug discovery and marketing and translating these needs into next-generation information tools, Integrity^® provides users with a dynamic resource to make better decisions and drive higher quality results—from discovery to market—in less time.

Since its introduction in 2001, Integrity^® has been adopted by major pharmaceutical and biotechnology companies worldwide and by academic and health-care institutions to drive knowledge creation, target mission-critical milestones, and support strategic decisions in drug R&D.
