X-ray Crystallography & SBDD
Domainex has the expertise to undertake crystal screens and through its access to the synchrotron at Diamond Light Source (Oxfordshire, UK) can obtain high-resolution structures of fragment hits bound to target proteins. These can then be used by computational and medicinal chemists at Domainex to guide an efficient fragment elaboration process.
To view a successful fragment optimisation programme, please see our joint publication with Professor Terry Rabitts at the University of Oxford.
Orthogonal & Functional Testing
The Domainex Assay Biology team can establish competition assays to determine the mechanism of binding of identified screening hits and can use a range of orthogonal tests including:
- Saturation Transfer Difference (STD) – NMR
- Surface Plasmon Resonance (SPR)
- Differential Scanning Fluorimetry (DSF)
Once the project has progressed, the team can run cellular assays to further profile novel compounds received from the medicinal chemistry team. In parallel, in vitro ADME assays are run on the most promising compounds to help identify tractable leads.
