Sachem is a high-performance chemical cartridge for fingerprint-guided substructure and similarity search. Sachem GUI allows quick access to this functionality on our Sachem installation. Indexed databases include up-to-date versions of PubChem and ChEMBL.
We provide an indexing service that allows FAIR-style search in published chemical data. You can easily construct queries that contain chemical substructure and similarity search terms combined with protein or bioassay-related queries.
Mission: Interoperability in small molecules
The main goal of IDSM is to aggregate many different sources of information about small molecules into a single, logically coherent and semantically interconnected information source. This is achieved using the semantic web technologies. The data is explored and queried by the SPARQL query language; allowing to search through the vast amount of published chemical RDF data.
IDSM internals have been described in several articles:
