Symyx Technologies has announced that the SPRESI structure and reaction database from Infochem is now available to chemists via the Symyx Isentris data access, analysis and decision support system.
In combination with existing Symyx reaction databases, which provide extensive coverage of reactions, detailed experimental methodology, and links to online citations and in-house reaction data, the SPRESI database offers chemists a synthesis planning solution.
Through molecule or reaction searches that include reaction substructure, exact match, transformation, and reaction mapping searches, researchers can simultaneously query across multiple reaction databases.
Citation linking to source literature, automatic links to commercial compound availability, display of retro-synthetic schemes, and the use of the synthesis planner to build multi-step reaction plans enable synthesis chemists to quickly design successful reaction plans.
The SPRESI database extends the existing set of reactions available from Symyx by providing access to an additional six million structures, 3.8 million reactions, and 28 million factual data entries extracted from 636,000 references and 164,000 patents published since 1974.
The SPRESI (speicherung und recherche strukturchemischer information) database was originally developed in the 1970s by the All-Union Institute of Scientific and Technical Information of the Academy of Sciences of the USSR (VINITI) in Moscow in collaboration with the Zentrale Informationsverarbeitung Chemie (ZIC) in Berlin.
The data collection includes chemical structures, reactions, chemical/physical properties, keywords and factual data abstracted from the most important journals in the field of organic chemistry.
Infochem has maintained and distributed the collection since 1991.
