MDL Information Systems, a provider of R&D informatics offerings for the life sciences and chemicals industries and acquired by Symyx Technologies, Inc. in 2007, was launched as a computer-aided drug design firm (originally named Molecular Design Limited, Inc.) in January 1978 in Hayward, California.


The company was founded by Stuart Marson and W. Todd Wipke.[1] "In other industries, aircraft and electronics, for example, automated design is taken for granted, so why not chemistry?" said Wipke. "But parts of such a system already exist, and Wipke,[2] after 15 years of research on computer synthesis at the University of California, Santa Cruz, and Marson, fresh from a Ph.D. at Stanford University and a postdoctoral stint at the University of California, Berkeley, are convinced that the current state of the art will support computer-assisted molecular design as a commercial enterprise.".[3] Employee #3 was Stephen Peacock, a colleague of Marson, and #4 was Jim Dill, a graduate student from Princeton, as was #5, Doug Hounshell, also a graduate of Princeton. MDL was the first company to provide interactive graphical registry and full and substructural retrieval. The company's initial products were first-of-their-kind systems for storing and retrieving molecules as graphical structures and for managing databases of chemical reactions and related data. These systems revolutionized the way scientists accessed and managed chemical information in the 1980s.

From its initial pioneering of computer handling of graphical chemical structures with MACCS (Molecular ACCess System) in 1979, MDL continued at the forefront of the field now known as cheminformatics. Innovations include:

  • Commercial system for interactive molecular modeling (PRXBLD, 1979)
  • Commercial system for computer handling of chemical reactions (REACCS, 1982)
  • Commercial system integrating chemical structures with data (MACCS-II, 1984)
  • PC-based chemistry database system, the Chemist's Personal Software Series (CPSS: ChemBase, ChemTalk/ChemHost, 1985)
  • Commercial system integrating chemistry drawing and word processing (ChemText, 1986)
  • Commercial 3D structure database (MACCS-3D, 1988)
  • Commercial system for storing structures of mixtures and formulations (MACCS-II Substance Module, 1989)
  • Commercial client-server system for managing chemical and biological information (MDL ISIS, 1991)
  • Commercial system for structure-based handling of generic structures (MDL Central Library, 1996)
  • Searchable, "live" chemical structures in Web pages (MDL Chemscape server, 1996)
  • Commercial system dynamically linking citations to electronic journal articles and patents (MDL LitLink, 1999)
  • Web-based commercial system indexing multiple structure databases and linking to synthetic methodology databases and major reference works (DiscoveryGate, 2002)
  • Software application for predicting potential carcinogenic risk of compounds based on their structures (MDL Carcinogenicity Module, 2003)
  • Complete, open, flexible and scalable n-tier informatics system supporting enterprise-wide business process, data and application integration for the life sciences (MDL Isentris, 2004)
  • Advanced structure drawing with All-Purpose Drawing Tool and custom template toolbars, MDL Draw, 2004)
  • Structure-searchable patent chemistry information (Patent Chemistry Database, 2004) and online pharmacological information (xPharm, 2004)
  • Key laboratory workflow applications (MDL Notebook electronic laboratory notebook, 2005)
  • Isentris-based application for building and managing compound registries (MDL Registration, 2006)
  • First electronically searchable FDA Drug Approval Packages (PharmaPendium, 2006)
  • Out-of-the-box Reaction Planner for exploring precursor steps, integration of proprietary and commercial data (Isentris 2.0 and 3.0, 2007).

In 1985, MDL moved its corporate headquarters from Hayward to a larger campus in San Leandro, CA. In 1987, MDL was purchased by Maxwell Communications Corporation. In 1993, the company was publicly offered as MDL Information Systems, Inc. (MDLI) on the NASDAQ stock exchange. In 1997, the company was purchased by Reed Elsevier, the Anglo-Dutch publisher and information provider, becoming a wholly owned subsidiary of Elsevier, a publisher of scientific, technical and medical information. In February 2006, Elsevier MDL moved its corporate headquarters from San Leandro to San Ramon, CA.

In October 2007, Elsevier MDL was acquired by Symyx Technologies, Inc., an R&D productivity company offering software, modular workflow tools and research services to global enterprises in the life sciences, chemicals, energy and consumer products industries. MDL has been merged with Symyx Software, and the new combined organization is based in San Ramon, CA. (Following the sale to Symyx of the infrastructure-related software applications and databases of MDL, the content assets of MDL retained by Elsevier — including CrossFire Beilstein, CrossFire Gmelin, the Patent Chemistry Database, xPharm and PharmaPendium — were integrated within Elsevier's Science & Technology operations.)

The August 2007 press release announcing Symyx Technologies' acquisition of MDL indicates that combining Symyx and MDL offerings creates an expanded set of software solutions and services to enhance R&D productivity in the life sciences, chemicals and energy industries. The press release states: "With this solution set, Symyx will be able to accelerate its customers' move toward paperless labs by integrating content, collaborative desktops, automation and information management for users, workgroups and the enterprise."
