A Small Molecule Reacts with the p53 Somatic Mutant Y220C to Rescue Wild-type Thermal Stability

The tumor suppressor p53 is the most mutated gene in cancer, and yet no therapeutics to date directly target the mutated protein to rescue wild-type function. In this study, we identify the first allele-specific compound that selectively reacts with the cysteine p53 Y220C to rescue wild-type thermal stability and gene activation.
