Heliquinomycin (Rubymycin, NSC 702208)

Antibiotic. DNA helicase inhibitor. Inhibits the DNA helicase activity of the human minichromosome maintenance (MCM) 4/6/7 complex. Topoisomerase I and II inhibitor (weaker than DNA helicase). DNA and RNA synthesis inhibitor in cell culture. Does not inhibit protein synthesis. Induces cell cycle arrest. Anticancer compound. Antibacterial against Gram-positive bacteria.
