Catalog No.S8426

For research use only.

10074-G5 is a c-Myc inhibitor that binds to and distorts the bHLH-ZIP domain of c-Myc (Kd = 2.8 µM), thereby inhibiting c-Myc/Max heterodimer formation and inhibiting its transcriptional activity (IC50 = 146 µM).

Biological Activity

Description 10074-G5 is a c-Myc inhibitor that binds to and distorts the bHLH-ZIP domain of c-Myc (Kd = 2.8 µM), thereby inhibiting c-Myc/Max heterodimer formation and inhibiting its transcriptional activity (IC50 = 146 µM).

In vitro

10074-G5 binds to and distorts the bHLH-ZIP domain of c-Myc, thereby inhibiting c-Myc/Max heterodimer formation and inhibiting its transcriptional activity. In vitro, 10074-G5 inhibits the growth of Daudi Burkitt's lymphoma cells and disrupts c-Myc/Max dimerization. Daudi cells accumulates 10074-G5, and the highest intracellular concentration is observed at 6 h. 10074-G5 inhibits c-Myc/Max dimerization in Daudi cells by approximately 75% at 4 h, and this inhibition is maintained through 24 h of incubation. Total c-Myc protein expression also decreases, and after 24 h exposure to 10 μM 10074-G5, c-Myc protein expression decreases approximately 40% compared with vehicle-treated control. 10074-G5 is cytotoxic in vitro against Daudi and HL-60 cells, which overexpress c-Myc [2].

In vivo The plasma half-life of 10074-G5 in mice treated with 20 mg/kg i.v. is 37 min, and peak plasma concentration is 58 μM, which is 10-fold higher than peak tumor concentration. The lack of antitumor activity probably is caused by the rapid metabolism of 10074-G5 to inactive metabolites, resulting in tumor concentrations of 10074-G5 insufficient to inhibit c-Myc/Max dimerization. Plasma 10074-G5 peak concentration (Cmax) of 58.5 ± 2.7 nmol/ml is observed at 5 min after intravenous administration of 20 mg/kg to mice bearing Daudi xenografts, 10074-G5 concentration in plasma declines rapidly. Except for lung, liver, and fat, tissue concentrations of 10074-G5 are lower than those of plasma at all time points[2].

Protocol (from reference)

Cell Research:[2]
  • Cell lines: Daudi cells
  • Concentrations: 10 μM
  • Incubation Time: 0, 1, 3, 6, or 24 h
  • Method: Daudi cells (3 × 108 cells in logarithmic growth) are incubated for 0, 1, 3, 6, or 24 h in 3 ml of complete medium containing 10 μM 10074-G5. After incubation, cells are harvested, split into two samples of 1.5 ml each, and overlaid in microcentrifuge tubes containing 0.5 ml of silicon oil. The tubes are centrifuged at 12,000g for 4 min. After centrifugation, the top 1 ml of medium is removed and stored in cryovials at −70°C until analysis. The remaining medium and silicon oil are carefully removed without disturbing the cell pellets. The sides of the tubes are cleaned with cotton-tipped applicators, and the cell pellets are stored at −70°C until analysis.
Animal Research:[2]
  • Animal Models: Specific-pathogen-free, female C.B-17 SCID mice
  • Dosages: 20 mg/kg
  • Administration: i.v.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
