Summary Gut microbes (genus: Bacteroides) increase sorivudine's toxicity.
sorivudine (PubChem CID: 5282192)
Bacteroides (Tax ID: 816)
increase toxicity
A toxic interaction has been reported in 18 Japanese people upon concomitant administration of sorivudine orally and 5-fluorouracil (5-FU). Bacteroides species are responsible for this toxicity owing to their production of (E)-5-(2-bromovinyl) uracil (BVU) metabolite which in turn deactivates dihydropyrimidine dehydrogenase (DPD) responsible for the metabolism of 5-FU (Nakayama et al, 1997).
