  • Scaffold-hopping and fragment-linking using the Cambridge Structural Database

    ​In this study we illustrate use of the Cambridge Structural Database to provide ideas for novel scaffolds giving an active inhibitor of known binding mode. Also, we identify good linkers between two fragments binding in different parts of the active site.

  • Validation of Docking Poses via Interaction Motif Searching

    Given a set of docking poses for a single ligand can we separate correct poses from high scoring but incorrect poses by comparing protein-ligand interaction motifs?

  • Validating protein-bound metals

    ​We compare the structure of a protein-bound metal and its coordination shell, with similar coordination structures in the CSD. This analysis may be useful in identifying errors in metal assignment or in coordination geometry in X-Ray derived protein models.

  • Designing a New Multi-Component API Form Based on a Known Structure

    This use case addresses the topic of how to design new multi-component, crystalline forms of an API purely based on the knowledge of one or more existing forms. The production of new multi-component forms will allow the physico-chemical properties of the solid to be modified (e.g. solubility, crystal habit and stability) without changing the biological efficacy of the API compound. If an isostructural series of API forms can be generated in this way, then tuning of physical properties may even be feasible.

  • Exploring symmetry related bias in conformational data from the CSD

    ​One frequently presented argument against using small molecule crystal structure data in conformer generation is that the close packing observed within crystal structures can significantly bias the observed conformations away from gas phase norms. We explore some well known cases where symmetry effects bias the distribution of conformational geometric information and to find the conditions that lead to this bias.
