The quest for a new cancer drug often begins when a protein target is implicated as an important driver in tumourigenesis. For cancer researchers, small molecules that block or stimulate such proteins can be valuable tools in research. Not only do they help us understand the role that the protein plays in cancer biology, but they also enable researchers to demonstrate which tumours are sensitive toward inhibition or stimulation with that protein target of interest, providing early clues as for patient selection and biomarker identification. Moreover, the knowledge that a small molecule can bind to such a protein builds confidence that this target is indeed “druggable,” which can provide a powerful stimulus to initiate a sustained effort to find medicines for that target.

Cancer drugs help millions of people every year by assisting them in living longer or by reducing side effects or symptoms. In some cases, cancer drugs can even prevent cancers from developing. But cancer drugs take a long time to carefully develop and test, and the process is expensive. We asked Dr. David Uehling, Scientific Advisor and Group Leader, Medicinal Chemistry Group in the Drug Discovery Program at OICR, to help explain the process and its challenges.
