Resources

A resource is the type of thing you are asking for (substance, catalog, gene, etc). Resources are written as plurals in the URL, indicating that the result is always a selection from among them. Each ZINC URL may specify only one resource. The URL syntax here covers both the web pages and the API. We currently support the following resources:

table name	Description	Use this resource when the answer to your question is
substances	molecules	molecules. All of ZINC12 queries are subsumed in the substance resource.
catalogs	vendor and annotated catalogs	a particular vendor or annotated catalog contributing to ZINC.
genes	UniProt Gene Names	a gene, which groups targets from different species for the same gene.
catalogitems	What they are called in the source catalog	about original catalog information
protomers	3D representations	various protonated and tautomerized forms of the molecule in 3D
targets	UniProt accession codes	species-specific molecular targets
activities	Observed	about individual observations of biological activity of small molecules.
purchasability	Definition of supported purchasability levels	about what levels of purchasability are curated in ZINC.
representatives	Cluster representatives	about chemical diversity of ligands for genes
clusters	Clustered compounds by gene	about compounds for genes organized by chemotype.
bioactivities	Definition of supported bioactivities	about what kinds of catalog-base
majorclasses	asdf asdf	asdfasfd sadf
targetclasses	asdf asdf	asdfasfd sadf
organisms	asdf asdf	asdfasfd sadf
modeltypes	asdf asdf	asdfasfd sadf
structures	asdf asdf	asdfasfd sadf
traits	asdf asdf	asdfasfd sadf
tools	asdf asdf	asdfasfd sadf
ecfp4s	lala	fingerprints

Historical note: In ZINC 12, the reference-table was always substances, and thus the result of any query was always a set of molecules. A few reports such as vendor and target listings were available via the webpages, but were not supported by the API. This is a substantial change that appeared first in ZINC 15.
