10058-F4 is a c-Myc inhibitor that inhibits c-Myc-Max dimerization and prevents transcriptional activation of c-Myc target gene expression[1]. 10058-F4 can promote caspase-3-dependent apoptosis and regulate autophagy[2]. 10058-F4 has anti-leukemia effects[3].
In vitro, 10058-F4 (0-200µM) treatment of ovarian cancer cell lines (SKOV3 and Hey cells) for 72h inhibited the proliferation of both cell lines in a dose-dependent manner, with IC50 values of 4.4µM and 3.2µML for SKOV3 and Hey cells, respectively, induced cell cycle arrest and apoptosis, and reduced reactive oxygen species (ROS) and ATP generation[4]. 10058-F4 (60μM) treatment of NALM6 and CEM cells for 24h significantly enhanced dexamethasone (DXM)-induced cell growth inhibition, G0/G1 phase arrest and apoptosis[5]. 10058-F4 (0-150μM) treatment of leukemia cells (HL-60, U937 and NB4 cells) for 72h inhibited the proliferation of all three cell types in a dose-dependent manner, induced cell cycle arrest and apoptosis, and myeloid differentiation[6].
In vivo, 10058-F4 (25mg/kg/day) was administered intraperitoneally to mice with acute colitis, which weakened the LiCl-induced colon regeneration effect and reduced the expression of Ccnd2 and Cad[7]. 10058-F4 (15mg/kg) was administered intraperitoneally to mice with PANC-1 cell xenografts for 30 days, 10058-F4 alone had no significant effect on tumorigenesis, but when used in combination with gemcitabine, it significantly attenuated tumorigenesis and reduced PCNA-positive cells and TUNEL-positive cells[8].
