Designed for discovery of novel PPI inhibitors
40 640 compounds
Having a pivotal role in multiple cellular processes, protein-protein interactions (PPIs) are responsible for the effects linked to the blockage of the substrate binding site. There are numerous examples of drug candidates that were withdrawn from clinical trials due to the unexpected effects of direct antagonists. This fact outlines the importance of developing new potent protein-protein interactions inhibitors.
We have carefully selected 40 640 diverse compounds specifically targeting PPIs. All compounds are stored as dry substances and they can be acquired in diverse custom formats. Using our PPI Library for hit discovery you receive multiple benefits allowing you to save on time and costs in lead generation:
- Dry stock of over 4.4M compounds for hit resupply and hit expansion.
- Low-cost synthesis of analogues within only 3 weeks through our REAL Database technology
- Medicinal chemistry support enhanced with on-site broad ADME/T panel
You have also an option to screen the Library directly at Enamine. In this case, we will be happy to offer discount on library cost depending on the collaboration scope.

Library design
Systemic analysis of available structural data of numerous PPIs allowed us to develop dedicated approach to the library design. We have analyzed more than 20 different protein-protein complexes to highlight specific features of majority of potent inhibitors in this area. Several specific recognition patterns, like α-helix, β-sheet, PDZ-, PBD and bromodomains were used in the library design. As a result of Ligand- and Structure based in silico screening, we created the selection of compounds featuring:
- Specific recognition patterns, including hot spots analysis, key amino acids, secondary/tertiary structures, α-helices, ‘hot loops’ and specific protein domains affinity.
- Lead-like properties and sp3-rich core structural motifs. Compounds passed all including affiliated MedChem filters including PAINS.
- Latest chemistry and novel building blocks. Identified hits can be readily followed with synthesis of new analogs through REAL Database technology.
