Product Usage Information

10058-F4 is supplied as a lyophilized powder. For a 10 mM stock, reconstitute 1 mg of powder in 0.40 mL of DMSO. Working concentrations and length of treatment can vary depending on the desired effect.

Storage

Store lyophilized at room temperature, desiccated. In lyophilized form, the chemical is stable for 24 months. Once in solution, store at -20ºC and use within 1 month to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

Background

The small-molecule 10058-F4 inhibits c-Myc, a transcriptional regulator involved in cell proliferation, differentiation, and apoptosis. Dysregulation of the oncoprotein c-Myc is common in human cancers. 10058-F4 inhibits transactivation of gene expression by c-Myc-Max heterodimers by disrupting the association between c-Myc and the transcription factor Max (1). 10058-F4 treatment of acute myeloid leukemia cells inhibited c-Myc expression and induced apoptosis and cell arrest at G0/G1 (2). In a mouse neuroblastoma model, 10058-F4 inhibited transactivation by N-Myc-Max, resulting in cell cycle arrest, apoptosis, and tumor growth reduction (3). Ovarian cancer cells treated with 10058-F4 displayed reduced cell proliferation and enhanced effects of chemotherapeutic drugs. The 10058-F4 inhibitor likely upregulates FOXO transcription factors and downstream genes involved in ovarian G1 cell cycle arrest, apoptosis, and autophagic cell death (4). 10058-F4 promoted increased expression of thioredoxin-interacting protein (TXNIP) in triple-negative breast cancer drug-resistant cells, which promoted reactive oxygen species synthesis and reversed doxorubicin-induced chemotherapy resistance (5).
