[Allele-specific inhibitors of mutant KRAS are in the focus of RASopathy consortium].

The RASopathy consortium was built from research groups of the Budapest University of Technology and Economics, Eötvös Loránd University, Semmelweis University and two startups: KINETO Lab Ltd. and Fototronic Ltd. The goal was to design and test novel covalent and allele-specific KRAS small molecular inhibitors. KRAS is the most frequently mutated human oncogene which was unsuccessfully targeted until recently. The consortium established G12C-expressing bacterial and human cancer cell models (homo- and heterozygous variants) of lung, colorectal and pancreatic tumors. Using covalent fragment and acrylamide warhead libraries we were able to select novel candidates of small molecular G12C-specific inhibitors which were compared to published best-in-class drug candidates.
