10074-G5 is an inhibitor of c-Myc-Max dimerization with an IC₅₀ of 146 μM.

IC50: 15.6 μM (Daudi cells), 13.5 μM (HL-60 cells)^[1], 146 μM (c-Myc–Max)^[2]

10074-G5 inhibits the growth of Daudi Burkitt’s lymphoma cells and disruptes c-Myc/Max dimerization. The IC₅₀ values against Daudi and HL-60 cells are 15.6 and 13.5 μM, respectively^[1]. 10074-G5 binds the Myc peptide Myc353-437 with a K_d value of 2.8 μM in the region Arg363-Ile381. 10074-G5 binds in a cavity that is created by a kink (Asp379-Ile381) in the N-terminus of an induced helical domain (Leu370–Arg378)^[3].

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].

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].
