General description

A cell-permeable benzoxadiazole compound that is shown to preferentially disrupt the interactions of c-Myc-Max, Mad1-Max, and Myf5-HEB, over those of 31 other pairs of HLH-, ZIP-, and HLH-ZIP-containing proteins. Similarly to 10058-F4 (Cat. No. 475956), 10074-G5 is shown to selectively inhibit the c-Myc-dependent growth of rat fibroblast cell line TGR1 and effectively suppress c-Myc-dependent transcription activity. Binding studies using various mutated and truncated c-Myc constructs reveal that 10074-G5 targets c-Myc helix-1 region between aa residues 363 and 381 (KD = 4.4 µM), while 10058-F4 interaction site is located within aa residues 402 through 412 (KD = 13 µM).

Endothelial dysfunction is prominent in atherosclerosis, hypertension, diabetes, peripheral and cardiovascular diseases, and stroke. Novel therapeutic approaches to these conditions often involve development of tissue-engineered veins with ex vivo expanded endothelial cells. However, high cell number requirements limit these approaches

c-Myc is a transcription factor that plays a crucial role in cellular homeostasis, and its deregulation is associated with highly aggressive and chemotherapy-resistant cancers. After binding with partner MAX, the c-Myc-MAX heterodimer regulates the expression of several genes, leading to
