Decreased immunosuppression associated with antitumor activity of 5-deoxy-5-fluorouridine compared to 5-fluorouracil and 5-fluorouridine.
5-Fluorouracil (5-FUra), 5-deoxy-5-fluorouridine (5'dFUrd), and 5-fluorouridine were compared for their relative antitumor activity, their capacity to inhibit leukocyte exudation and macrophage (macrophage) killing of tumor cells in vivo and in vitro, and their ability to induce leukopenia and monocytopenia. 5'dFUrd was less toxic than 5-FUra and exhibited anti-Ehrlich ascites activity over a w...
متن کاملSensitivity of human, murine, and rat cells to 5-fluorouracil and 5'-deoxy-5-fluorouridine in relation to drug-metabolizing enzymes.
Six cell lines differing in histological origin were studied regarding the growth inhibitory effect of fluoropyrimidines in relation to their metabolism. The human colon carcinoma cell line WiDr was most sensitive to 5-fluorouracil (FUra) (50% growth inhibitory concentration, 0.7 microM) and to its analogue 5'deoxy-5-fluorouridine (5'dFUR) (50% growth inhibitory concentration, 18 microM). The m...
متن کاملEffect of Skimmed Milk on the Absorption and Metabolism of 5-Fluorouracil (5-FU) in Animals
Several modalities of drug administration have been investigated to improve bioavailability and to reduce 5-FU related toxicity. The aim of present study was to evaluate the effect of skimmed milk on the absorption and metabolism of 5-FU in rabbits, mice and dogs. It was further aimed to determine its route related toxicity in rabbits. Plasma concentration of both 5-FU and its metabolit...
