The Comparative Toxicogenomics Database (CTD) presents scientifically reviewed and curated information on chemicals, relevant genes and proteins, and their interactions in vertebrates and invertebrates. It integrates sequence, reference, species, microarray, and general toxicology information to provide a unique centralized resource for toxicogenomic research. The database also provides visualization capabilities that enable cross-species comparisons of gene and protein sequences.

This resource is a provider. This means that while it may have its own prefix, it actually reuses the identifiers provided by the mesh prefix. For all use cases, you should use mesh instead of ctd.chemical.

Pattern for CURIES

Compact URIs (CURIEs) constructed from CTD Chemical should match this regular expression:

Example CURIE
Part Of
ctd (not directly registered)
Metaregistry CTD Chemical

The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for ctd.chemical with 1 unique external prefixes.

Registry Name Registry Metaprefix External Prefix Curate
BioContext biocontext CTD.CHEMICAL
Biolink Model Registry biolink CTD.CHEMICAL logo miriam ctd.chemical
Name-to-Thing Name-to-Thing logo n2t ctd.chemical

Providers are various services that resolve CURIEs to URLs. The example CURIE ctd.chemical:D001151 is used to demonstrate the provides available for ctd.chemical. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
