Chemistry Commons

Jump to navigation Jump to search

The Chemistry Commons is a platform to connect investigators with mutual interests in ligand discovery.

  • synthetic organic chemists who have developed new reaction schemes and wonder whether they make useful compounds
  • biologists and medicinal chemists seeking new reagents for biology and always looking for new compounds
  • as well as computational chemists, who can assist both camps.


  • Synthetic organic chemists wish to make their chemistry relevant to biology
  • Chemists use the Chemistry Commons to articulate and enumerate libraries of accessible compounds
  • Libraries in 2D and 3D are prepared and made available.
  • Biologists (and the computational chemists they work with) search these databases for molecules that look interesting
  • Compounds are prioritized for synthesis
  • A collaborative agreement is reached between the synthetic chemist and the biology lab testing the compounds
  • Compounds are produced, tested, and, ideally, some compounds will work.

How to get started

If you are a synthetic organic chemist, with a new reaction scheme, please use our tools to define your reaction. CC:Library preparation

If you are a biologist or medicinal chemist, seeking new compounds for your target, search the libraries in 2D using Smallworld CC:Smallworld and Arthor CC:Arthor or in 3D using docking or other 3D methods. CC:Docking

If you would like to participate in the Chemistry Commons, but are not quite sure how to get started, please reach out to chemistry4biology at gmail dot com or join us for Weekly office hours

Naming conventions

ZINC-22 molecules have the form ZINCnprx01234567 where

  • n indicates the heavy atom count of the molecule
  • p indicates the calculated logP bin of the molecule
  • r indicates the research group that originated the reaction scheme
  • x indicates the ordinal number of the reaction scheme from that research group
  • 01234567 is the ordinal for each molecule in this space (monotonic increasing from 1)
  • numbers are in radix-62, thus [0-9][a-z][A-Z]

Synthetic organic research groups may elect to perform the synthesis, or to enable it to be performed by a third party.
