MODELING OF 5-FLUOROURACIL INFULENCE ON ACTIVITY OF ITS’ METABOLIC ENZYMES M. Stashkevych O. O. Bogomolets National Medical University Abstract This article presents the results of model experiment which involved intraperitoneal administration of 5-fluorouracil (5-FU) to rats with further determination of the activity of its’ key metabolic enzymes: dehydropyrimidine dehydrogenase (DPD) and thymidine phosphorylase (TP), in various time intervals after 5-FU injection. These results were compared to ones from the control group of animals which did not receive 5-FU. It was revealed that 5-FU has the suppressive influence on TP up to 12 hours after injection and does not affect activity of DPD. As these enzymes are responsible for 5-FU activation (TP) and degradation (DPD) the observed influence of the drug is desired effect associated with lesser toxic impact on normal cells. Keywords: 5-fluorouracil, dehydropyrimidine dehydrogenase, thymidine phosphorylase, rat liver
