Here are all source catalogs in ZINC in a compact tile view. For more information, to browse or download, click on the catalog. This includes both vendor catalogs containing molecules you may buy as well as annotated compounds that have biological activity but are not for sale.
These databases have been provided to us under collaborative agreements with each respective catalog owner. Catalogs have been filtered for drug discovery relevance, and thus compounds in the original catalog may not be in ZINC. Some documentation on ZINC subsets is available.
ZINC may be used free of charge for research by individuals and institutions. Whereas you are free to share the results of a ZINC search or a screen of molecules from ZINC, you may not redistribute major portions of ZINC without the express written permission of John Irwin.
