    Metabolism-Based Identification of a Potent Thrombin Receptor Antagonist
    摘要:
    The metabolism of our prototypical thrombin receptor antagonist 1, K-i = 2.7 nM, was studied and three major metabolites (2,4, and 5) were found. The structures of the metabolites were verified independently by synthesis. Compound 4 was shown to be a potent antagonist of the thrombin receptor with a K-i = 11 nM. Additionally, compound 4 showed a 3-fold improvement in potency with respect to 1 in an agonist-induced ex-vivo platelet aggregation assay in cynomolgus monkeys after oral administration; this activity was sustained with 60% inhibition observed at 24 h post-dose. Compound 4 was highly active in functional assays and showed excellent oral bioavailability in rats and monkeys. Compound 4 showed a superior rat enzyme induction profile relative to compound 1, allowing it to replace compound 1 as a development candidate.

    正交几何中硅的β效应
    摘要:
    已经通过制备1-(三甲基甲硅烷基)双环[2.2.2]辛-2-醇(5-OH)及其磺酸酯衍生物研究了对硅的β效应的感应贡献。三甲基甲硅烷基与离去基团的键之间5的二面关系接近正交,从而防止了超共轭或桥连对β效应的任何贡献。硅的任何残留效应都应来自感应。与无硅模型双环[2.2.2]辛-2-基甲苯磺酸酯(7-OTs)相比,甲苯磺酸酯的比率在80-97%的三氟乙醇水溶液中于20-72%时为1.2-1.3。 35℃。这种微不足道的β效应与在近平面上的几何值大约为10 5,在渐近几何上的近似值为10 4以及在10 12上近似为10 12。在反平面几何形状处。完全的二面角依赖性类似于超共轭机制而不是桥接所期望的余弦平方曲线,归纳贡献很小。

    日期:2000.7.1
    The scope and limitations of a tandem 5-exo dig cyclization/Claisen rearrangement sequence involving appropriately substituted 4-alkyn-1-ols as an efficient "one-pot" route to fused tricyclic ring systems is described. The reaction rates were found to be strongly dependent on the nature of the terminal substitutent of the triple bond. In some cases the entire sequence was found to proceed in good yield

    quinones anti-6 and syn-7, which were obtained from the kinetic resolution of the racemic diene. In all cases, (SS)-(2-p-tolylsulfinyl)-1,4-naphthoquinone reacted from the less hindered face of the more reactive s-cis conformation, to form products in good enantiomeric excesses. Steric effects and torsional interactions in the corresponding approaches account for the observed pi-facial diastereoselectivities
