CAMBRIDGE, Mass.--Spotfire, a provider of research and development software, announced the availability of two new products recently. Leads Discoverer, already in use by DuPont Pharmaceuticals, is a system for accessing, analyzing, and sharing high-throughput screening and chemical structure information on the internet or an intranet. Chemists at DuPont employ the program to access high-throughput datasets residing in Oracle databases and to integrate the data with chemical structure data from MDL Information Systems' ISIS database, Spotfire said.
