title: On-line storage and retrieval of chemical information. II. Substructure and biological activity searching.
abstract: An improved interactive system for searching substructure and biological activity data has been developed. Features of the system include a two-level substructure search (fragment screen and atom by atom) and an expanded biological activity data base. The system operates on a file of about 150 000 compounds.
