This project explored the potential of the Inverse Electron Demand Diels Alder (IEDDA) cycloaddition (click chemistry) to support drug discovery projects.

We investigated the use of the IEDDA for the determination of the selectivity profile and target engagement of lead compounds, for the cellular localisation of proteins via fluorescence imaging and also for the induction of protein degradation.

Dr Honorine Lebraud is currently Alliance Management Associate, Astex Pharmaceuticals, UK.
