Plicamycin (INN, also known as mithramycin; trade name Mithracin) is an antineoplastic antibiotic produced by Streptomyces plicatus. It is an RNA synthesis inhibitor.[1] The manufacturer discontinued production in 2000.


Plicamycin has been used in the treatment of testicular cancer,[2][3] Paget's disease of bone,[4][5] and, rarely, the management of hypercalcemia.

Plicamycin has been tested in chronic myeloid leukemia.[6]

Plicamycin is currently used in multiple areas of research, including cancer cell apoptosis[7] and as a metastasis inhibitor.[8]

One elucidated pathway shows it interacts by cross-binding chromatin GC-rich promoter motifs, thereby inhibiting gene transcription.[9]
