Cell experiment:

10074-G5 is dissolved in DMSO and diluted with culture medium. Daudi cells or HL-60 cells in logarithmic growth are treated with 10074-G5 (1-100 μM). After 72 h, 50 μL of 1 mg/mL MTT is added to each well and incubated for 4 h. At the end of the incubation, medium containing drug and MTT is removed from each well, and 100 μl of DMSO is added, followed by shaking for 5 min. The absorbance at 570 nm is read[1].

Animal experiment:

Mice: C.B-17 SCID mice bearing Daudi xenografts are stratified into the following groups (10 mice/group): control; vehicle control (0.01 ml/g body weight, once daily for 5 days); positive control, doxorubicin (2.5 mg/kg/dose, one dose every 4 days for three doses); and 10074-G5 (20 mg/kg/dose, once daily for 5 days). Mice are dosed intravenously on the appropriate schedule, and body weights and tumor volumes are recorded twice weekly[1].

10074-G5 is a c-Myc inhibitor [1].

c-Myc is a bHLH-ZIP transcription factor involved in cell cycle progression, cellular growth and metabolism, differentiation, and apoptosis. Overexpression of c-Myc has been identified in numerous cancers, including prostate, pancreatic, lung, breast, and colon cancers, B-cell lymphoma, and leukemias. Alterations in c-Myc have been associated with cancer aggressiveness and poor treatment prognosis. Inhibition of c-Myc is an attractive pharmacological approach in the development of new anticancer treatments. Inactivation of c-Myc rapidly results in cell-cycle arrest, apoptosis, tumor vascular degeneration, redifferentiation of tumor cells, and ultimately tumor regression [1].

The IC50 values of 10074-G5 against Daudi cells and HL-60 cells were 15.6 ± 1.5 μM and 13.5 ± 2.1 μM, respectively. 10074-G5 (10 μM) inhibited c-Myc/Max dimerization and decreased total c-Myc protein expression. In C.B-17 SCID mice bearing Daudi xenografts, treatment with 10074-G5, (20 mg/kg i.v., for 10 consecutive days) significantly inhibited tumor growth with no effects on body weight.
