Description: Brivudine, also known as bromovinyl-deoxyuridine, is a uridine derivative and nucleoside analog with pro-apoptotic and chemosensitizing properties. In vitro, bromovinyl-deoxyuridine (BVDU) has been shown to downregulate the multifunctional DNA repair enzyme APEX nuclease 1, resulting in the inhibition of DNA repair and the induction of apoptosis. In addition, this agent may inhibit the expression of STAT3 (signal transducer and activator of transcription 3), which may result in the downregulation of vascular endothelial growth factor (VEGF). BVDU has also been found to inhibit the upregulation of chemoresistance genes (Mdr1 and DHFR) during chemotherapy. Overall, the gene expression changes associated with BVDU treatment result in the decrease or prevention of chemoresistance. In addition, this agent has been shown to enhance the cytolytic activity of NK-92 natural killer cells towards a pancreatic cancer cell line in vitro.

Additional Information

According to, Brivudine is approved for use in Germany and other European countries including Italy. Brivudine is a similar drug to acyclovir The compound was first synthesized by scientists at the University of Birmingham in the UK in the 1970s. It was shown to be a potent inhibitor of the herpes simplex virus Type 1 (HSV-1) as well as the varicella zoster virus (VZV) by Erik De Clercq at the Rega Institute for Medical Research in Belgium in 1979. In the 1980s the drug became commercially available in East Germany, where it was marketed as Helpin by a pharmaceutical company called Berlin-Chemie.
