Pharmacology

Chromomycin A3 is a glycosidic antineoplastic antibiotic isolated from the bacterium Streptomyces griseus. Chromomycin A3 reversibly binds to guanine-cytosine (G-C) base pairs in the minor groove of DNA, thereby inhibiting RNA synthesis. This agent is used as a fluorescent chromosome dye. (NCI04)
