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 کاملHydrolysis of capecitabine to 5'-deoxy-5-fluorocytidine by human carboxylesterases and inhibition by loperamide.
Capecitabine is an oral prodrug of 5-fluorouracil that is indicated for the treatment of breast and colorectal cancers. A three-step in vivo-targeted activation process requiring carboxylesterases, cytidine deaminase, and thymidine phosphorylase converts capecitabine to 5-fluorouracil. Carboxylesterases hydrolyze capecitabine's carbamate side chain to form 5'-deoxy-5-fluorocytidine (5'-DFCR). T...
متن کاملConversion of 5'-deoxy-5'-methylthioadenosine and 5'-deoxy-5'-methylthioinosine to methionine in cultured human leukemic cells.
5'-Deoxy-5'-methylthioadenosine and 5'-deoxy-5'-methylthioinosine, which are metabolized to the methionine precursor, 5-methylthioribose-1-phosphate, by 5'-deoxy-5'-methylthioadenosine phosphorylase and purine nucleoside phosphorylase, respectively, can serve as sources of methionine for cultured HL-60 promyelocytic leukemia cells. CCRF-CEM T-cell leukemia cells, which lack 5'-deoxy-5'-methylth...
متن کاملAnticachectic activity of 5'-deoxy-5-fluorouridine in a murine tumor cachexia model, colon 26 adenocarcinoma.
Murine colon 26 adenocarcinoma causes a progressive weight loss and physiological changes associated with cachexia when it grows to a certain size. By the use of this tumor model several types of cytostatics were examined for their ability to alleviate cachexia. Among them, 5'-deoxy-5-fluorouridine could reverse a progressive weight loss and improve hypoglycemia, hyperglucocorticism, and hepati...
متن کاملInterferon-α Enhances 5′-Deoxy-5-Fluorouridine-Induced Apoptosis by ERK-Dependant Upregulation of Thymidine Phosphorylase
5-Florouracil (5-FU) is the basic agent used in the treatment of gastric cancer. Capecitabine, a prodrug of 5-FU, displays increased antitumor efficacy compared with 5-FU in the clinic. 5'-Deoxy-5-fluorouracil (5'-DFUR), the metabolite of capecitabine, is converted to 5-FU by the enzyme thymidine phosphorylase (TP), which is present at high concentrations in human tumors. In this study, we inve...
