Library Design

< Hit DiscoveryFragment Screening >



ZoBio is constantly updating its fragment library that currently contains approximately 1,900 commercially available, high quality, compounds. The library is designed as a diverse screening set and can therefore be screened against a variety of target classes, while maintaining a good hit rate. The compounds are rigourously quality controlled and dynamically updated. In addition to the diversity library, ZoBio has a smaller, proprietary fragment library that contains chemical scaffolds which have been synthesized by Mercachem. The specifications of both fragment libraries is shown in the table below.

Creating and screening of a target focused library is a way to access a greater fraction of available fragment space. Based on known structural information of the binding mode of, for example, the endogenous ligand for the target, a pharmacophore screening model is constructed. Such a model describes the 3D pharmacoporic features that are important for binding and are used to select rule of 3 compliant fragments.
