sorivudine

Sorivudine (BV-araU) 是口服有效的，嘧啶核苷抗代谢药物。它的抗病毒活性来自某些 DNA 病毒中存在的特定胸苷激酶选择性转化为核苷酸，从而反过来会干扰病毒 DNA 合成。

(E)-5-(2-Bromovinyl)uracil (BVU) is a pyrimidine base and an inactive metabolite of the antiviral agents sorivudine and (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU) that may be regenerated to BVDU in vivo. BVU irreversibly inactivates dihydropyrimidine dehydrogenase (DPD) in an NADPH-dependent manner. It enhances the efficacy of the chemotherapeutic agent and DPD substrate 5-fluorouracil in a P388 murine leukemia model when administered at a dose of 200 μmol kg, increasing survival time.
