Alternative Name: Quinomycin A

Chemical Name: N-(2-Quinoxalinylcarbonyl)-O-[N-(2-quinoxalinylcarbonyl)-D-seryl-L-alanyl-3-mercapto-N,S-dimethylcysteinyl-N-methyl-L-valyl]-D-seryl-L-alanyl-N-methylcysteinyl-N-methyl-L-valine-(81)-lactone-cyclic (37)-thioether

Biological Activity

Highly potent and selective HIF-1α inhibitor (IC50 = 29.4 pM). Selectively inhibits HIF-1 binding to the VEGF promoter without affecting the binding of AP-1 or NF-κB. Inhibits colony formation of cancer stem cells (CSC) with a 100-fold selectivity over normal hematopoietic progenitor cells. Eradicates mouse lymphomas and human AML xenografts by eliminating CSCs.
