New in the 1.4 API release 

2 new data sets and their corresponding API calls (shown below)

1) DisGeNet target-disease associations

These API calls use URIs inputs that correspond to either diseases or targets (proteins or genes). The disease identifiers correspond to UMLS CUIs, Mesh ids or ConceptWiki and can use several namespaces, e.g.,, or

2) neXtProt nanopublications for tissue expression (PREVIEW mode)

These API calls use URIs that correspond to either tissues or targets.  The tissue identifiers correspond to the Caloha tissue ontology from neXtProt.  The identifiers for tissues are from the Caloha ontology (, operational now).

The 'Tissues for protein' and "Proteins for tissue' calls can be filtered by the neXtProt "gold" or "silver" evidence flag.

New results in Compound Information call

Compound Information: Previously the Compound Information called returned results only when a compound had data in the ConceptWiki, Chemical Registry System, and Chembl.  This requirement for data to be present in all 3 resources has been relaxed to remove the requirement for ConceptWiki data which will allow data from the Chemical Registry System to be returned (e.g. SMILES) when the compound is not found in other data sources.

New batch methods for Information calls

Compound Information, Target Information, Disease Information, and [Preview] Tissue Information calls are now available with a "batch" method.  Many URIs can be submitted in one query if separated by a '|'.
