QSAR Information System database

Computer-based chemical information systems are now widely used for the storage and retrieval of chemical structure information. Efficient searching algorithms are available which allow structure-based searches to be carried out on databases containing many thousands, or even millions, of chemical compounds. In addition, the ease with which machine-readable structural data can be manipulated has led to a wide range of related activities, such as computer-aided s)uithesis design and studies of quantitative structure-activity relationships (QSAR). ... 

ASTER ASTER (Assessment Tools for the Evaluation of Risk) was developed in US EPA. It is a database of toxic effects AQUIRE (AQUatic toxicity Information Retrieval) integrated with an expert system QSAR and valuation techniques for activity prediction http //www.epa.gov/med/Prods Pubs/aster.htm...
