Echinomycin is a cyclic peptide of the family of quinoxaline antibiotics that was originally isolated from Streptomyces echinatus. It is thought to act as a bifunctional DNA intercalator. Echinomycin has a binding site size of four base pairs. The strong binding sites for echinomycin contain the central two-base-pair sequence 5'-CG-3'. Echinomycin interferes with HIF-1 DNA binding in a sequence-specific fashion. It was brought into clinical trials by the NCI 20 years ago based on its antitumor activity. It has been extensively tested in phase I-II clinical trials. Nausea, vomiting, reversible liver enzyme abnormalities, and allergic reactions were the most common toxicities encountered. However, minimal or no antitumor activity was found in phase II clinical trials.

In Vitro Use Guide

Echinomycin very potently inhibited hypoxic induction of luciferase expression in U251-HRE in a dose-dependent fashion with an EC50 of 1.2 nmol/L. U251-HRE cells were treated with Echinomycin at 5, 10, and 20 nmol/L for 4 hours and then washed and incubated under normoxic or hypoxic conditions for 36 hours. 94%, 80%, and 42% of hypoxiainduced luciferase expression was restored in cells in which Echinomycin was washed out after 4-hour treatment at 5, 10, and 20 nmol/L, respectively, indicating that the DNA-binding activity of Echinomycin is in fact reversible.
