MYCMI-6 (NSC354961) is a potent and selective endogenous MYC:MAX protein interactions inhibitor. MYCMI-6 blocks MYC-driven transcription and binds selectively to the MYC bHLHZip domain with a Kd of 1.6 μM. MYCMI-6 inhibits tumor cell growth in a MYC-dependent manner (IC50apoptosis.
MYCMI-6 (NSC354961) (6.25 μM
48 hours) selectively suppresses MYC-driven tumor cell growth with high efficacy[1]. MYCMI-6 significantly inhibits growth of Burkitt’s lymphoma cells (Mutu, Daudi and ST486) - another classical example of a MYC-driven tumor, having translocations of MYC to one of the immunoglobulin loci - in a dose-dependent manner with an average GI50 of 0.5 μM. Treatment of MCF7 cells with the MYCMI-6 for 24 hours significantly decreased MYC:MAX isPLA signals to 7%. Titration showed an IC50 for inhibition of MYC:MAX of less than 1.5 μM for MYCMI-6 by isPLA. MYCMI-6 inhibits the MYC:MAX heterodimer formation with an IC50 of 3.8 μM. MYCMI-6 efficiently inhibits anchorage-independent growth of MYCN-amplified neuroblastoma cells with GI50 values of [1].
MYCMI-6 (20 mg/kg
i.p.
daily for 1-2 weeks) induces massive apoptosis and reduces tumor cell proliferation, tumor microvasculature density and MYC:MAX interaction in a MYC-dependent xenograft tumor model[1].
