Berubicin HCl

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 200490

CAS#: 293736-67-1 (HCl salt)

Description: Berubicin hydrochloride is the hydrochloride salt of the anthracycline derivative berubicin with potential antineoplastic activity. Berubicin intercalates into DNA and interrupts topoisomerase II activity, resulting in the inhibition of DNA replication and repair, and RNA and protein synthesis. Unlike other anthracycline derivatives, this agent crosses the blood-brain barrier (BBB).

Berubicin belongs to a novel class of anthracycline derivatives that cross the blood-brain barrier and show significant potential for the treatment of primary and secondary brain cancers. While other drugs in this class (for example, doxorubicin) are some of the most broadly used and effective cancer therapies, they do not cross the blood-brain barrier and are not effective in treating brain tumors. These compounds are potent inhibitors of topoisomerase II, a DNA repair enzyme. Overexpression of topo II has been identified as an indicator of aggressive cell proliferation and a negative prognostic indicator in patients with primary brain cancers. Topo II inhibition is likely to be effective in combination with temozolomide, the current standard therapy in glioblastoma.   see .
