Documented Uses

• Mesh Heading: Antibiotics, antineoplastic, fluorescent dyes, nucleic acid synthesis inhibitors, protein synthesis inhibitors
• Oligosaccharide antibiotic produced by Streptomyces argillaceus n. Sp. And S. Tanashiensis. Hungarian patent 155,679 (1969 to Gyogyszerkutato Intezet).
• ELABORATED DURING CULTURE OF SUITABLE STRAIN OF STREPTOMYCES, RECOVERED BY EXTRACTION WITH 1-BUTANOL, & PURIFIED BY CHROMATOGRAPHY. ELUATE CONTAINS MAGNESIUM SALT OF MITHRAMYCIN WHICH YIELDS ANTIBIOTIC ON ACIDIFICATION & ETHYL ACETATE EXTRACTION.
• For the treatment of testicular cancer, as well as hypercalcemia and hypercalciuria associated with a variety of advanced forms of cancer.
• Plicamycin, which was formerly known as mithramycin, is an antibiotic that is used as an anticancer agent in the therapy of testicular and germ cell cancers. Plicamycin causes acute hepatic injury that arises within days of starting therapy, but is usually transient and asymptomatic and rarely leads to jaundice. Plicamycin has not been approved for use as cancer chemotherapy in the United States, but continues to be used on an investigational basis.
• Plicamycin is of limited value in the treatment of neoplastic disease because of its severe toxicity.
