BND: Biochemical Names Database

BND is a curated, versioned, public domain database of terms for naturally-occurring small molecules of biochemical interest. It is in the public domain and can be freely downloaded.

BND version 1.5 has 3642 primary terms with 9996 synonyms. This version of BND has added 5006 terms showing the relationships among different types of isomers; 434 terms that subsume other terms; terms that indicate different types of ambiguities and variations (especially for Markush structures); and terms that indicate database-specific usages. For detailed statistics, please see BND's statistics.

BND uses The Agora as an electronic infrastructure for the scientific community to query, deposit, review, and curate biochemical information. One can query BND itself for synonyms, or query other participating databases using synonyms instead of whatever term the other database uses as primary. We encourage the community to deposit additional terms, synonyms and relations to BND, and to critique the deposit of others.
