چکیده

5-Fluorouracil (5-FU) has effectively inhibited fibroblast proliferation to prevent scar formation and bleb failure after glaucoma filtering surgery. To identify more potent but less toxic antiproliferative drugs, the authors studied cell attachment and proliferation of 5-FU metabolites: 5-fluorouridine (FUR), 5-fluorodeoxyuridine (FUdR), 5-fluorouridine-5'-monophosphate (FUMP), and 5-fluorodeoxyuridine-5'-monophosphate (FdUMP) on human Tenon's fibroblasts in vitro.

Effects of 5-Fluorodeoxyuridine and Related Halogenated Pyrimidines on the Sand-Dollar Embryo

The embryo of the sand-dollar (Echinarachnius parma) was exposed to various concentrations of fluorinated pyrimidines immediately after fertilization. FUDR (5-fluorodeoxyuridine) was most active, and a concentration of 2 to 4 mgamma/10 cc. (0.8 to 1.6 x 10(-6) m.eq./liter) blocked development at the early blastula stage. Larger doses interrupted development at the same stage. This effect was pr...

Comparative studies of fluorinated pyrimidines with various cell lines.

pound (1 7) with useful clinical activity ( 16), a wide variety of pyrimidines and nucleoside analogs of various types have been synthesized and their biologic and biochemical activities de scribed. This laboratory has been engaged in the synthesis and study of a number of other fluorinated pyrimidines (cf 14), among which the most interesting are FUR, FUDR (14), and F3TDR (18). Recently we hav...

The multidrug resistance protein 5 (ABCC5) confers resistance to 5-fluorouracil and transports its monophosphorylated metabolites.

5'-Fluorouracil (5-FU), used in the treatment of colon and breast cancers, is converted intracellularly to 5'-fluoro-2'-deoxyuridine (5-FUdR) by thymidine phosphorylase and is subsequently phosphorylated by thymidine kinase to 5'-fluoro-2'-dUMP (5-FdUMP). This active metabolite, along with the reduced folate cofactor, 5,10-methylenetetrahydrofolate, forms a stable inhibitory complex with thymid...

The anti-tumor activity of the fluorinated uracil derivatives, 5-fluorouracil (FU), 5-fluorouridine (FUR), 5-fluorodeoxyuridine (FUDR), and 5fluoroorotic acid (FO), prepared by Duschinsky, Pleven, Malbica, and Heidelberger (9) 1 have been demonstrated in mice and rats by Heidelberger et al. (11-13). These results have been confirmed and extended by Law (14), Liebling and Humphreys (15), and our...

Mechanisms of action of FdUMP[10]: metabolite activation and thymidylate synthase inhibition.

FdUMP[10] is a multimer of FdUMP, a suicide inhibitor of thymidylate synthase (TS), and was designed to bypass resistance to 5-fluorouracil (5FU). The aim of the study was to compare the effect of FdUMP[10] with 5FU and 5-fluoro-2-deoxyuridine (FUdR) in their efficacy to inhibit their target TS in resistant cells. Therefore cell lines FM3A/0, FM3A/TK- (deficient in thymidine kinase) and FM3A/TS...
