MK-1775 is an inhibitor of Wee1, a protein that regulates the G2 mitosis checkpoint in response to DNA damage. MK-1775 exhibits anticancer chemotherapeutic activity. In acute myelogenous leukemia (AML) cells, this compound decreases phosphorylation of CDK1/2 and induces double-stranded DNA breaks. In animal models of various cancers, MK-1775 increases survival times and decreases tumor size, particularly when co-administered with other treatments.
