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 13C- and 31P 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 P2Y2 receptors (P2Y2R) 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 μM (in NG108-15 cells) and of 0.1 μM (in CF/T43 cells), respectively. 5-Substituted UTP derivatives were agonists at the P2Y2R, but were less potent than UTP. 5-Ethyl-UTP, for example, exhibited an EC50 value of 99 μM at P2Y2R of NG108-15 cells and proved to be a full agonist. With increasing volume of the 5- substituent of UTP derivatives, P2Y2 activity decreased.
Process for the preparation of 5-(2-bromovinyl)-uridine

The invention relates to (E)-5-(2-bromovinyl)-uridine and its derivatives of general formula VI, STR1 wherein R1 stands for a hydrogen atom, C1-8 alkanoyl group, benzoyl group or a benzoyl group substituted in para position either with a C1-4 alkyl group or a halogen atom, and a process for preparing them by brominating 2',3',5'-tri-O-acyl-5-ethyl-uridine of general formula IV, STR2 wherein R is identical with R1, except where R1 stands for a hydrogen atom, dehydrohalogenating the resulting dibromo compound of general formula V STR3 and optionally deacylating it. The resulting compounds of general formula VI are exhibiting significant potency against Herpes simplex virus species and are of remarkably low acute toxicity.
