10058-F4 is a c-Myc inhibitor that inhibits the c-Myc-Max associationn and function. It prevents the growth of fibroblasts in a c-Myc-dependent manner. Downregulates human telomerase reverse transcriptase and enhances chemosensitivity in human hepatocellular carcinoma cells. Induces cell cycle arrest, apoptosis and myeloid differentiation in human acute myeloid leukemia. 10058-F4 inhibits the MYCN/Max interaction leading to cell cycle arrest, apoptosis and neuronal differentiation in MYCN-amplified neuroblastoma cells.
