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 K d of 1.6 μM. MYCMI-6 inhibits tumor cell growth in a MYC-dependent manner (IC 50 <0.5 μM). MYCMI-6 is not cytotoxic to normal human cells. MYCMI-6 induces apoptosis [1] .
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 GI
50
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 IC
50
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 IC
50
of 3.8 μM. MYCMI-6 efficiently inhibits anchorage-independent growth of
MYCN
-amplified neuroblastoma cells with GI
50
values of <0.4 μM

Cell Viability Assay [1]
Cell Line: | MYCN -amplified neuroblastoma cells (IMR-32, Kelly and SK-N-DZ), MYCN -non-amplified neuroblastoma cells (SK-N-F1, SK-N-AS and SK-N-RA) |
Concentration: | 6.25 μM |
Incubation Time: | 48 hours |
Result: | Reduced growth of the MYCN -amplified cell lines significantly stronger than the MYCN -non-amplified cell lines. |
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] .

Animal Model: | 6-8 weeks old athymic nude mice (bearing MYCN-amplified SK-N-DZ neuroblastoma cells) [1] |
Dosage: | 20 mg/kg body weight |
Administration: | I.p.; daily for 1-2 weeks |
Result: | A dramatic increase in the extension of apoptotic areas in the tumors and a significant increase in non-proliferative areas as determined by Ki67 staining in tumors. |
