  5-Substituted UTP derivatives as P2Y2 receptor agonists

  摘要：

  A series of 5-alkyl-substituted UTP derivatives, which had been synthesized previously with a moderate degree of purity, was resynthesized, purified, and characterized. Synthetic and purification procedures were optimized. New spectroscopic data, including C-13- and P-31 NMR data, are presented. Phosphorylation reactions yielded a number of side products, such as the 2'-, 3'-, and 5'-monophosphates, the 2',3'-cyclic monophosphates, and the 2',3'-cyclic phosphates of the 5'-triphosphates. Furthermore, raw products were contaminated with inorganic phosphates, including cyclometatriphosphate, phosphate, and pyrophosphate. The uracil nucleotides were investigated for their potency to increase intracellular calcium concentrations by stimulation of P2Y(2) receptors (P2Y(2)R) on NG108-15 cells, a mouse neuroblastoma x glioma cell line, and in human basal epithelial airway cells, including a cystic fibrosis (CF/T43) cell line. UTP exhibited EC50 values of ca. 1 mu M (in NG108-15 cells) and of 0.1 mu M (in CF/T43 cells), respectively. 5-Substituted UTP derivatives were agonists at the P2Y(2)R, but were less potent than UTP. 5-Ethyl-UTP, for example, exhibited an EC50 value of 99 mu M at P2Y(2)R of NG108-15 cells and proved to be a full agonist. With increasing volume of the 5-substituent of UTP derivatives, P2Y(2) activity decreased. (C) 1999 Editions scientifiques et medicales Elsevier SAS.

  Synthesis of three novel 2'-deoxy-2'-[F-18]fluoro-1-beta-D-arabinofuranosyluracil derivatives [F-18] FPAU, [F-18]-FBrVAU, and [F-18] FTMAU is reported. The compounds were synthesized by coupling of 1-bromo-2-deoxy-2- fluoro sugars with corresponding silylated uracil derivatives. In vitro cell uptake indicated that all three compounds are taken up selectively in RG2TK+ cells with negligible uptake in RG2 cells. The results indicate that [F-18]FBrVAU and [F-18]FTMAU have better uptake profiles in comparison to [F-18]FPAU and have potential as PET probes for imaging HSV1-tk gene expression.
