| | QUINOMYCIN A Usage And Synthesis |
| Description | Hypoxia-inducible factor-1 (HIF-1) is a transcription factor that controls genes involved in glycolysis, angiogenesis, migration, and invasion. Echinomycin is a cell-permeable inhibitor of HIF-1-mediated gene transcription. It acts by intercalating into DNA in a sequence-specific manner, blocking the binding of either HIF-1α or HIF-1β to the hypoxia-responsive element. Echinomycin reversibly inhibits hypoxia-induced HIF-1 transcription activity in U215 cells with an EC50 value of 1.2 nM. It inhibits hypoxia-induced expression of vascular endothelial growth factor, blocking angiogenesis and altering excitatory synaptic transmission in hippocampal neurons. Echinomycin also impairs expression of survivin, enhancing the sensitivity of multiple myeloma cells to melphalan. | | Uses | Quinomycin A is a cyclic depsipeptide metabolite. Quinomycin A has broad activity against bacteria, fungi and viruses, and has found application as an antitumor agent. Quinomycin A acts by bifunctional intercalation of nucleic acids. Recent research has shown quinomycin A to be an extremely potent inhibitor of hypoxia-inducible factor-1 (HIF-1). This transcription factor plays an essential role in tumor progression and metastasis. | | Uses | Quiniomycin A is a cyclic depsipeptide metabolite.

It binds to DNA via bifunctional intercalation, blocking the binding of HIF-1α, a transcription factor important in tumor growth. Echinomycin selectively eliminated cancer stem cells in a study with mouse lymphoma and human AML xenogeneic models, eradicating the lymphomas. Recently, echinomycin was also found to act as an antibiotic adjuvant having synergistic effects with novobiocin in gram negative bacteria. | | storage | Store at -20°C | | References | 1) Kong?et al.?(2005),?Echinomycin, a small-molecule inhibitor of hypoxia-inducible factor-1 DNA-binding activity; Cancer Res.,?65?9047
