  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.

  that result in selective phosphoryl transfer to phenols and aliphatic alcohols. Optimization was performed by monitoring the impact of base, solvent, and molar equivalence on reactivity. We identified ZnBr2/Cs2CO3 as matched conditions for phenol phosphoryl transfer and Ti(OR)4/NiPr2Et as matched conditions for aliphatic alcohol phosphoryl transfer. The selectivity of the optimized conditions was then

  开发了一种筛选方法来识别导致选择性磷酰基转移到酚和脂肪醇的催化剂。通过监测碱、溶剂和摩尔当量对反应性的影响来进行优化。我们确定ZnBr 2 /Cs 2 CO 3作为苯酚磷酰基转移的匹配条件，Ti(OR) 4 /N i Pr 2 Et 作为脂肪醇磷酰基转移的匹配条件。然后测试优化条件对 3-(4-羟基苯基)-1-丙醇（同时含有脂肪族羟基和酚羟基的二醇）磷酸化的选择性。在每种情况下，均以大于 80% 的分离产率形成匹配的单磷酸盐产物。
