    Enamine extend collaboration with prominent Swiss Biotech

    A new multi-year drug discovery agreement will focus on CNS drug discovery

    Kyiv, Ukraine, February 24 2021 - Enamine Ltd. a provider of drug discovery services empowered with the world’s largest collections of building blocks, fragments and screening compounds announced today that it has extended its long-standing research collaboration with Addex Therapeutics Ltd (SIX: ADXN and Nasdaq: ADXN), a clinical-stage pharmaceutical company specialized in allosteric modulation-based drug discovery and development. Enamine is providing Addex with its integrated capability in medicinal chemistry, pharmacology and ADME/PK (Absorption, Distribution, Metabolism, Excretion/Pharmacokinetics) to efficiently support Addex’ small molecule CNS drug discovery programs.

3D Pharmacophore Diversity Set

Ro5 compliant 3D Pharmacophoric Diversity Set

4 800 compounds

3D-Pharmacophore Diversity set (3DS) was designed for optimal coverage of pharmacophoric shapes maintaining high level of diversity. 3DS library will be a useful tool for screening against a wide range of both validated and novel biological targets. Carefully developed selection algorithm ensures quality of initial hits enabling fast hit follow-up using stock-available analogs and validated synthetic chemistry protocols.

Library design

Wide range of filtering methods was used for selection of drug-like compounds with maximum 3D-pharmacophore coverage and uniform distribution:

  • Combination of cheminformatics protocols to provide the rational distribution in chemical space: bCUT descriptors, cell-based diversity analysis in 2D and 3D plots, both h-s and h-suppressed binary descriptors were used.
  • Strict filtering using 3D structure-based analysis. Only centroid molecules were selected for further processing with 3-point pharmacophore comparative analysis.
  • 2Dprop analysis (ClogP, logS tPSA, HBD, HBA, rotatable bonds count, ring number), PMI and fingerprint-based diversity (linear fingerprints).

Spatial representation of compounds distribution in 3D chemical space based on a set of 2D properties, PCA approach.

PMI plot demonstrates good distribution of selected compounds subset by molecular shape (diversity set represented as light green circles).

 

Example of 3D-pharmacophore with spatial constraints.

Pharmacophore space with each unique 3-point pharmacophore was generated based on 3D pharmacophore descriptors and represents potential interaction map between compound and biological target.

The following molecular features were used to create 3-point pharmacophores: H-bond donors, H-bond acceptors, positively charged centers, negative charges and hydrophobic areas (pharmacophore graph with triangle fingerprints).
