Biophysical Assays for Integrated Drug Discovery

Precisely measuring binding affinity, kinetics, stoichiometry, and thermodynamics, helps you optimize hits, guide medicinal chemistry, and progress stronger candidates into cellular screening and beyond.

At Concept Life Sciences, our biophysical assays provide the molecular-level insight you need to make confident, data driven decisions to strengthen your discovery strategy.

Integrated drug discovery and biophysical assays

Cell-based and biochemical screening alone can obscure the true nature of target engagement. Biophysical assays directly address common obstacles by answering 7 critical questions early:

1. Is my compound truly binding the target?
2. Does my compound bind to closely related targets?
3. How many compound molecules bind to the target?
4. How strong is the interaction?
5. How quickly does the interaction take place, and how stable is that interaction?
6. What drives binding – is it enthalpic or entropic?
7. Why do some hits fail to translate into cellular potency?

By generating quantitative, label-free interaction data, biophysical assays enable you to de risk programs before significant time and cost are invested downstream.

Integrated biophysical support across hit to to to lead

With over 300 drug discovery programs supported through hit to lead optimization, our clients work with us because we combine:

• ‍Advanced biophysical technologies covering a wide range of targets and modalities.
• Experienced scientists who design fit-for-purpose assay strategies.
• Integrated drug discovery expertise, linking biophysics with biochemical and cellular assays, medicinal chemistry and DMPK.

This seamless integrated approach ensures your biophysical data is not generated in isolation but translated into actionable insight that accelerates decision making and reduces costly delays.

Biophysical assay techniques

Using an unparalleled suite of technologies, we help you fully characterize how your drug candidate interacts with its target and what that means for next steps, they include:

‍

This breadth allows us to design bespoke biophysical screening strategies aligned to your target class, modality, and development stage.

Biophysical data that drives hit to to lead optimization

Biophysical insight is most powerful when combined with chemistry and biochemical and cellular assay data. Our teams work closely with medicinal chemists and assay development scientists to:

• Optimize potency, selectivity, and residence time.
• Explain structure–activity relationships (SAR).
• Guide rational compound design.
• Improve translation from biochemical to cellular assays.

The result is smoother progression from hit identification to high quality lead compounds. Whether you are validating hits, troubleshooting cellular screening data, or optimizing leads, our biophysical assays provide the clarity needed to move forward with confidence.

What makes us different from typical CRO providers

Many CROs offer biophysical assays as isolated services, generating data, but leaving interpretation, translation, and next steps to you. This often results in fragmented decision making, misaligned assays, and repeated cycles of chemistry and screening

Concept Life Sciences is different. As an integrated drug discovery partner, we embed biophysical assays within a broader scientific and strategic framework:

Integrated from day one – Biophysics aligned with assay development, medicinal chemistry, and cellular biology.

Decision driven assay design – Experiments built to answer progression-critical questions, not just generate data.

Translation focused insight – Clear linkage between molecular interactions and functional or cellular outcomes.

Flexible engagement models – From discrete studies to fully integrated hit to lead programs.

This approach enables faster; more confident progression compared with transactional CRO models.

Designed for sponsors at critical decision points

Our clients typically engage us when:

• Cellular screening results do not correlate with biochemical data.
• Hit lists require robust triage before medicinal chemistry investment.
• Binding kinetics or residence time are suspected drivers of efficacy.
• Previous CRO data lacks clarity or reproducibility.
• Programs need to accelerate without expanding internal infrastructure.

By addressing these challenges early, our biophysical assays reduce attrition and improve ROI across hit to lead optimization.
