What is 5-Bromouridine?

Description

5-Bromouridine is an energy-related metabolite that is a precursor of uridine. 5-Bromouridine binds to the nuclear DNA in cells, where it can act as a transcriptional regulator. 5-Bromouridine is used in the treatment of malignant brain tumors, where it can inhibit tumor growth by binding to the dna of cancer cells and preventing the synthesis of proteins required for cell division.
