Chemical biology and molecular therapeutics initiative

One key goal of our work is to translate insights from fundamental research to improvements in the treatment of cancer. However, two major scientific challenges impede efforts to translate recent advances in our molecular understanding of cancer to new medicines for clinical application. First, many cellular processes that represent clinically validated opportunities for the treatment of cancer are mediated by macromolecular assemblies, such as protein-protein interactions, which, are not routinely accessible to conventional methods for the identification of chemical leads. This curtails the repertoire of ‘druggable’ targets for intervention using small molecules. Second, limitations in our understanding of the biological effects of new agents impede their early clinical development. This makes it difficult to select appropriate clinical indications and drug combinations during the transition from Phase I to Phase II clinical trials, leading to an unacceptably high attrition rate. We are developing a palette of new approaches to tackle these challenges, including new strategies to enlarge the ‘druggable’ target repertoire, to identify biomarkers for drug responsiveness, and to use this information in early-phase clinical trials.

Interdisciplinary approaches to extending the repertoire of ‘druggable’ targets. 

 

This has led to strong collaborations with colleagues in physics (Payne), chemistry (AbellBalasubramanianSpring), biochemistry (Blundell,Hyvonen) and clinical medicine (JodrellTuveson), besides pharma and biotech companies. We participate in the Cambridge Molecular Therapeutics Programme, a University-wide interdisciplinary initiative to pioneer approaches for the discovery and development of drugs against new types of molecular targets, as well as the Physics of Medicine programme.

These links support a range of ongoing projects in our laboratory that use interdisciplinary tools to investigate biological problems, and to create small molecules as tools for chemical biology and to seed the development of drugs.
