About p53 p53 plays a pivotal role in preventing abnormal cells from becoming a tumor by inducing programmed cell death. Mutant p53 takes on oncogenic properties that endow cancer cells with a growth advantage and resistance to anti-cancer therapy. The p53 Y220C mutation is associated with many cancers, including but not limited to breast, non-small cell lung cancer, colorectal, pancreatic, and ovarian cancers. About PC14586 PC14586 is a first-in-class, small molecule, p53 reactivator designed to selectively bind to the crevice present in the p53 Y220C mutant protein, hence, restoring the wild-type, or normal, p53 protein structure and tumor suppressing function.
