Biologically Active Compound Library

Life Chemicals offers its Bioactive Screening Compound Library of over 8,000 drug-like small molecules as a perfect starting point for phenotypic (cell-based) and target-based high throughput screening (HTS) drug discovery research projects.

The selected structurally diverse bioactive molecules have been tested in functional, binding and other biological assays and have confirmed bioactivity in vitro and/or in vivo against about 600 unique biological targets of pharmaceutical interest.

Our biologically relevant compound collection includes enzyme inhibitors, receptor ligands, and ion channel regulators for different molecular targets (such as kinases, GPCRs, ion channels) and activity areas (e.g., biotechnology, epigenetics, antiviral or antibacterial research). It is aimed for screening against complex biological targets, unclassified proteins and enzymes.

The compound selection can be customized based on your requirements, cherry picking is available.

Please, contact us at for any additional information and price quotations.

Compound Selection

The Screening Library has been designed on the basis of the ChEMBL database (v25) which contained:

  • 1,929,473 compound records
  • 1,592,191 compounds
  • 13,968,617 annotated activities
  • 1,212,831 assays
  • 11,019 targets

Initial dataset was curated automatically and manually, data clustered. Each entry is supplied with a link to its Compound Report Card and Bioactivity Summary. High compound purity (> 90%) is confirmed by LCMS and/or NMR analytical data.

Activity Profiling

The target activity records of the presented set of bioactive compounds meet the following criteria:

  • Inhibition > 30 %
  • Ki < 10 µM
  • Kd < 10 µM
  • Potency < 10 µM
  • XC50 < 10 µM
  • Residual Activity < 50 %
  • EC50 < 10 µM
  • CC50 < 10 µM
  • AC50 < 10 µM
  • IZ > 10 mm
  • MIC < 10 µg/mL
  • MIC < 10 µM

The Advanced Screening Subset of highly active compounds (the selection criteria: activity values < 1 µM, inhibition > 70 %), as well as focused subsets for specific target types and therapeutic areas, are available on request.
