Actinomycin D is used as an anti-neoplastic antibiotic. It is also used to inhibit RNA polymerase and is a potent inducer of apoptosis. It is also used as a potent antibiotic that binds to the GpC steps of DNA. Inhibits DNA-primed RNA polymerase by complexing with DNA via deoxyguanosine residues. A DNA-intercalator with growth inhibitory activity against certain leukemias and sarcomas. At higher concentrations, DNA polymerase is inhibited. Inhibits cell growth and colony formation in synchronized HeLa cells.
