These databases have been provided to us under collaborative agreements with each respective vendor. Molecules in the original catalogs may not appear in ZINC because they do not pass our filters, or they have not been processed yet. 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.

The following limits are in effect:
  • Molecules per mol2 or SDF format file: 100,000
  • Entries per flexibase file 20,000
  • Typical size of mol2/sdf/flexibase files: 20 to 100 MB
  • Number of large files that may be downloaded concurrently: 2
In the downloads above, we offer four formats: SMILES, mol2, SDF, and flexibase formats. Most docking programs we know of use mol2. We urge you to not download Flexibaseunless you are using DOCK3.5.54.

We have generated protonated forms in 3 pH ranges. The reference structure ("ref") is a single representative structure at pH 7. The middle pH range ("mid") contains additional protonated forms obtained by titrating protons with pKa between 5.75 and 8.25. The low pH range ("lo") contains additional protonated forms between pH 4.5-7 and the high pH range ("hi") contains additional protonation forms between pH 7-9.5.

Databases are divided into chunks for easier download. mol2 and sdf slices are 100MB or less uncompressed. Flexibase are 160MB or less uncompressed.

To download all files in the usual pH range (5.75-8.25) use "Usual". To download databases for metalloenzymes use "Metal", which adds the pH range 7-9.5 to usual above. For the entire pH range 4.5-9.5 please use "All".

We also offer tables of Molecular Properties, purchasing information, and Inchi files.
