Benefits of Direct-to-Biology (D2B) in Drug Discovery

Drug discovery is a complex and time-consuming process that requires the seamless integration of multiple disciplines and technologies. D2B has revolutionised the field by combining ‘plate-based chemistry’ with rapid biological screening. The key benefits of employing Domainex’s D2B expertise in your integrated drug discovery project include:

Plate-Based Chemistry:

  • Expert compound library design
    • Computational design to increase chemical diversity
    • Molecular modelling and in silico property predictions
    • Assessment of scaffolds for plate-based chemistry
  • Accelerated compound synthesis
  • Efficient resource allocation
  • Miniaturisation of reactions - Enhances efficiency and reduces environmental impact
  • High throughput purification can be included
  • Access to Domainex’s team of highly skilled synthetic chemists

Rapid Screening:

  • Customised assay development by our team of highly skilled biologists
    • For TPD projects: Includes assessment of POI binding, ternary complex formation and the level of cellular protein degradation (e.g. Nano-Glo® and automated Western blotting)
  • Efficient hit validation
  • Early mechanism of action insights 
  • De-risks development
  • Generates rapid SAR, including EPSA and ChromLogD
  • Allows data-driven decision making
  • Rapid optimisation of ADME properties

Domainex’s D2B Workflow

Up to 380 compounds can be generated in a single plate and screened using the workflow below:

Direct to biology workflow
  • Plate-based reaction optimisation is undertaken prior to D2B to ensure workflow efficiency and to minimise reagent usage. 
  • Utilising this process, 1,000s of compounds can be synthesised and screened in less than 1 month
  • Automated QC and analysis, using UPLC MS, is conducted to allow a heat-map overview to be produced to assess the quality of each plate (see Figure 1)
  • Hits can be observed even when a relatively low sample purity is observed.

D2B combines plate-based chemistry with rapid screening, synergistically enhancing the efficiency and success of drug discovery. These methods allow researchers to explore rapidly chemical space, identify hits, validate their biological activity, gain early insights into mechanism of action and asses the ADME properties, ultimately streamlining the development of novel and effective therapeutics. By embracing these cutting-edge techniques, Domainex will accelerate your drug discovery programmes and help you to bring life-changing medicines to patients more efficiently and effectively.
