Elsevier MDL releases major DiscoveryGate® upgrade to boost research productivity

SAN LEANDRO, CA - June 13, 2005 - Elsevier MDL is pleased to announce the release of an enhanced version of DiscoveryGate, the company's highly acclaimed content platform for chemistry and life sciences research. Leveraging MDL® Isentris® technology, the new DiscoveryGate provides improved performance and usability-helping researchers rapidly find critical scientific information from a broad array of sources.

"With more than 300 customers and thousands of users, DiscoveryGate is already a significant success in the global pharma and biotech R&D arenas," said Elsevier MDL CEO Lars Barfod. "Customer requirements for improved productivity played a key role in this major upgrade, which provides faster responses to complex queries, improved usability and easy installation and maintenance. DiscoveryGate continues to demonstrate the impressive enterprise-scale capabilities of the MDL Isentris development framework for science."

DiscoveryGate ( www.discoverygate.com) integrates information from 25 chemistry and pharmacology databases on a single hosted platform, providing direct links to the primary literature and integration with customers' internal systems.

For any given search, the platform provides comprehensive results in the context of the original query. For example, researchers querying specific reaction databases can use new "Also Found In" links to simultaneously retrieve related information from other chemistry, molecular biology, bioactivity, metabolism/toxicology, chemical sourcing and synthetic methodology databases.

The database links extend to important new sources including the xPharm® database, which is the world's largest pharmacological reference work, and MDL® Patent Chemistry Database, an extensive new reaction and factual database for scientists in chemistry and the life sciences.
