Application

Echinomycin has been used for inhibition of hypoxia-inducible factor 1.

Actions biochimiques/physiologiques

Echinomycin is an antitumor antibiotic and potent hypoxia inducible factor 1α (HIF-1α) inhibitor. 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.
