Active Ingredient History

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.   NCATS
