PubChem expands

Thomson Scientific, the leading database publisher, recently announced that it has added 2.2 million chemical structures to PubChem (http://pubchem.ncbi.nlm.nih.gov), the freely available database for chemical information run by the National Center for Biotechnology Information (NCBI) at the U.S. National Institutes of Health (NIH). This represents an approximate 22-percent increase in the size, since PubChem claims to have more than 10 million structures. All of these structures have biologically interesting activity and represent approved drugs as well as compounds that have been investigated by R&D in the pharmaceutical industry.
