| Action against Disease Model | MK-1775 | Drug Info | MK-1775. This compound inhibits phosphorylation of CDC2 at Tyr15 (CDC2Y15), a direct substrate of Wee1 kinase in cells. MK-1775 abrogates G(2) DNA damage checkpoint, leading to apoptosis in combination with DNA-damaging chemotherapeutic agents such as gemcitabine, carboplatin, and cisplatin selectively in p53-deficient cells. In vivo, MK-1775 potentiates t uMor growth inhibition by these agents, and cotreatment does not significantly increase toxicity. The enhancement of antit uMor effect by MK-1775 was well correlated with inhibition of CDC2Y15 phosphorylation in t uMortissue and skin hair follicles | [3] | |
