Targeted and
Specialty Libraries

Ion Channel Focused, Lead-like and Drug-like Compounds

The IONCore Library is a computationally selected library of more than 6,000 lead-like small molecules
based on similarity to 3D pharmacophore fingerprints generated from published compounds with
activity against ion channel targets. More than 320 novel scaffolds are represented in the IONCore
Library, and in-stock analogs are available for any compound identified as a hit.

  • Lead-like and Drug-like compounds based on novel scaffolds
  • Potential activity against a range of ion channels
  • Custom select from more than 10,000 compounds

Compounds showing activity against ion channel targets were extracted from public, scientific
databases. 3D conformers were generated for each agonist or antagonist compound, and 3D
pharmacophore fingerprints were generated from the 3D conformers. These fingerprints were then
compared to the 3D pharmacophore fingerprints generated for virtual compounds based on novel
scaffolds designed by ChemBridge. Virtual compounds with a high similarity to a published active
fingerprint were synthesized and included in the IONCore Library selection.
