PRMT5-IN-53

PRMT5-IN-53 is an orally active, gut-restricted PRMT5 inhibitor, exhibiting pIC50 values of ≥ 9.7 against both hPRMT5 and mPRMT5. It binds to the PRMT5:MEP50 complex with a KD of 11.3 pM. In mice, PRMT5-IN-53 effectively inhibits intestinal PRMT5, significantly reducing both the number and size of polyps while avoiding systemic hematologic toxicity such as anemia and neutropenia. This compound is applicable in colorectal cancer research, particularly for familial adenomatous polyposis (FAP) .
