  Pyrimidine Nucleotides with 4-Alkyloxyimino and Terminal Tetraphosphate δ-Ester Modifications as Selective Agonists of the P2Y₄ Receptor

  摘要：

  P2Y(2) and P2Y(4) receptors are G protein-coupled receptors, activated by UTP and dinudeoside tetraphosphates, which are difficult to distinguish pharmacologically for lack of potent and selective ligands. We structurally varied phosphate and uracil moieties in analogues of pyrimidine nucleoside 5'-triphosphates and 5'-tetraphosphate esters. P2Y(4) receptor potency in phospholipase C stimulation in transfected 1321N1 human astrocytoma cells was enhanced in N-4-alkyloxycytidine derivatives. OH groups on a terminal delta-glucose phosphoester of uridine 5'-tetraphosphate were inverted or substituted with H or F to probe H-bonding effects. N-4-(Phenylpropoxy)-CTP 16 (MRS4062), Up(4)-[1]3'-deoxy-3'-fluoroglucose 34 (MRS2927), and N-4-(phenylethoxy)-CTP 15 exhibit >= 10-fold selectivity for human P2Y(4) over P2Y(2) and P2Y(6) receptors (EC50 values 23, 62, and 73 nM, respectively). delta-3-Chlorophenyl phosphoester 21 of Up(4) activated P2Y(2) but not P2Y(4) receptor. Selected nucleotides tested for chemical and enzymatic stability were much more stable than UTP. Agonist docking at CXCR4-based P2Y(2) and P2Y(4) receptor models indicated greater steric tolerance of N-4-phenylpropoxy group at P2Y(4). Thus, distal structural changes modulate potency, selectivity, and stability of extended uridine tetraphosphate derivatives, and we report the first P2Y(4) receptor-selective agonists.

  Small ligands interacting with the phosphotyrosine binding pocket of the Src SH2 protein

  摘要：

  Various small fragments bearing phosphate, phosphonate or phosphonic acid moieties have been prepared through parallel synthesis and their binding potencies evaluated on the Sre SH2 protein using a BIAcore assay. This provided us insight into the requirement of the Src SH2 pTyr binding pocket and some promising small ligands have been characterised. (C) 2002 Elsevier Science Ltd. All rights reserved.
