ML00253764 is a selective melanocortin receptor 4 ( MC4R ) antagonist, can induce apoptosis by inhibiting ERK1/2 and Akt phosphorylation, and has anticancer activity. In Vitro ML00253764 (0.001-50 μM, 24 h or 72 h) has significant time- and concentration-dependent inhibitory activity on the proliferation of human glioblastoma cells, and the IC 50 value for U-118 cells is 6.56 μM, which can induce U -87 cells apoptosis and show significant inhibition of ERK1/2 phosphorylation in both cell lines. MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo ML00253764(30 mg/kg, s.c., daily, 34 days) can inhibit inhibit tumor growth in CD nu/nu male mice infected with U-87 cells . MCE has not independently confirmed the accuracy of these methods.
