Elsevier MDL announced on December 19 that it is working with the National Institutes of Health (NIH) to help catalog additional information on the biological properties of small molecules in the freely available PubChem database. A press release says that Elsevier MDL will enrich the growing PubChem resource for the scientific community by furnishing chemical structures from Elsevier’s xPharm database, giving scientists with an xPharm license the ability to move from biological data in PubChem to more focused pharmacology data in xPharm that is essential to drug research. You can use ChemSpy to search PubChem and track down any one of more than five million molecules.
UPDATE: Mar 2007 – All of this is kind of superseded by ChemSpider.com
