Application

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

Biochem/physiol Actions

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

Echinomycin is an antitumor antibiotic secondary metabolite isolated from streptomycetes, whose core structure is biosynthesized by nonribosomal peptide synthetase (NRPS). The echinomycin biosynthetic pathway was successfully reconstituted in Escherichia coli. NRPS often contains a thioesterase domain at its C terminus
