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. Several different structures are currently reported in different places all with the same chromomycin core, but with different stereochemistry in the glycoside chain, a 1999 study has re-investigated the compound and proposed a revised structure.[2]
Uses
[edit]Plicamycin has been used in the treatment of testicular cancer,[3][4] Paget's disease of bone,[5][6] and, rarely, the management of hypercalcemia.
Plicamycin has been tested in chronic myeloid leukemia.[7]
Plicamycin is currently used in multiple areas of research, including cancer cell apoptosis[8] and as a metastasis inhibitor.[9]
One elucidated pathway shows it interacts by cross-binding chromatin GC-rich promoter motifs, thereby inhibiting gene transcription.[10]
