First-in-class beta-catenin inhibitor as treatment for colorectal cancer
With more than 1.9 million new cases and 935,000 related deaths in 2020, colorectal cancer (CRC) is the third most common cancer in men and the second in women. While surgery is the main treatment option for lower grade CRC, patie...

Descripción del proyecto
With more than 1.9 million new cases and 935,000 related deaths in 2020, colorectal cancer (CRC) is the third most common cancer in men and the second in women. While surgery is the main treatment option for lower grade CRC, patients with unresectable lesions are treated with chemotherapy. Related therapies are associated with severe drawbacks, such as systemic toxicity, low response rate, and unpredictable resistance. Molecular targeted therapies have emerged as a promising strategy to specifically target cancer cells. For CRC, the inhibition of the Wnt signalling pathway has moved into the focus of novel therapeutic approaches as it is hyperactivated in 80% of all cases. Within the pathway, the protein beta-catenin is considered a particularly attractive target. However, classic small molecule targeting strategies have failed to provide any approved drugs that inhibit beta-catenin so far.
We have identified a family of peptidomimetic agents that bind beta-catenin and inhibit its interaction with the TCF/LEF transcription factors. For the first time, it was possible to obtain a crystal structure of a synthetic molecule bound to a therapeutically very attractive site on beta-catenin. In addition, we have confirmed cellular activity of these inhibitors verifying selective inhibition of the Wnt signalling pathway. These findings provide the ideal starting point for the development of novel therapeutics for Wnt-dependent cancers, in particular for CRC. These first-in-class inhibitors will provide the basis for the development of therapeutics that selectively inhibit oncogenic Wnt signalling thereby affecting the viability of corresponding cancer cells. This can enable targeted therapies for Wnt-dependent forms of CRC.
