    New nonpeptide angiotensin II receptor antagonists. 3. Synthesis, biological properties, and structure-activity relationships of 2-alkyl-4-(biphenylylmethoxy)pyridine derivatives
    摘要:
    A novel series of nonpeptide angiotensin II (AII) receptor antagonists is reported, derived from linkage of the biphenylyltetrazole moiety found in previously described antagonists via a methyleneoxy chain to the 4-position of a 3-substituted 2,6-dialkylpyridine. When evaluated in an in vitro binding assay using a guinea pig adrenal membrane preparation, compounds in this series generally gave IC50 values in the range 0.005-0.5 muM. A variety of substituents was found to be effective at the 3-position of the pyridine ring. On intravenous administration in a normotensive rat model, the more potent compounds inhibited the AII-induced pressor response with ED50 values in the range 0.1-1.0 mg/kg. One of the compounds, 2-ethyl-5,6,7,8-tetrahydro-4-{[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methoxy}quinoline (26), demonstrated good oral activity in two rat models. At doses in the range 1-10 mg/kg po in AII-infused, conscious, normotensive rats, the compound exhibited a dose-related inhibition of the pressor response with a good duration of action at the higher doses. In a renal hypertensive rat model compound 26 showed a rapid and sustained lowering of blood pressure at a dose of 5 mg/kg po. Based on its profile, this compound, designated ICI D6888, has been selected for evaluation in volunteers.

  • Synthetic libraries of tyrosine-derived bacterial metabolites
    作者:Savvas N. Georgiades、Jon Clardy
    DOI:10.1016/j.bmcl.2007.10.058
    日期:2008.5
    The preparation of a collection of 131 small molecules, reminiscent of families of long chain N-acyl tyrosines, enamides and enol esters that have been isolated from heterologous expression of environmental DNA (eDNA) in Escherichia coli, is reported. The synthetic libraries of N-acyl tyrosines and their 3-keto counterparts were prepared via solid-phase routes, whereas the enamides and enol esters
    据报道,制备了 131 个小分子的集合,让人联想到长链 N-酰基酪氨酸、烯酰胺和烯醇酯家族,这些分子是从大肠杆菌环境 DNA (eDNA) 的异源表达中分离出来的。N-酰基酪氨酸及其3-酮对应物的合成库是通过固相途径制备的,而烯酰胺和烯醇酯是在溶液相中合成的。

    unsaturated ruthenium complex catalyzed the formation of a carbon-carbon bond between two judiciously chosen alkene and alkyne partners in good yield, and in a chemo- and regioselective fashion, despite the significant degree of unsaturation of the substrates. The resulting 1,4-diene forms the backbone of the cytotoxic marine natural product amphidinolide P. The alkene partner was rapidly assembled from (R)-glycidyl
    尽管底物具有显着的不饱和度,但配位不饱和钌络合物以良好的产率、化学和区域选择性的方式催化了两个精心选择的烯烃和炔烃伙伴之间碳-碳键的形成。由此产生的 1,4-二烯形成了细胞毒性海洋天然产物两栖内酯 P 的骨架。烯烃伴侣由 (R)-甲苯磺酸缩水甘油酯快速组装而成,它是单瓶连续三组分偶联过程的关键使用乙烯基锂和乙烯基氰铜酸酯。炔烃配偶体的合成利用了在螯合控制条件下由顺式乙酸衍生的烯丙基锡试剂的不寻常的反选择性加成。此外,还具有使用偶氮二羧酸酯-三苯基膦系统的显着E选择性E2工艺。还介绍了使用 β-内酯作为热力学弹簧来实现大内酯化的第一个例子。因此,氧杂环丁酮环被用作有效的保护基团,提高了该全合成的整体效率。这项工作也是进一步探讨钌催化的烯烃-炔烃偶联范围的机会,特别是使用烯炔,并描述了使用各种官能化底物的研究。

    Inhibition of dipeptidyl peptidase IV (DPP-4) is an exciting new approach for the treatment of diabetes. To date there has been no DPP-4 chemotype possessing a carboxy group that has progressed into clinical trials. Originating from the discovery of the structurally novel quinoline derivative 1, we designed novel pyridine derivatives containing a carboxy group. In our design, the carboxy group interacted
    抑制二肽基肽酶IV(DPP-4)是治疗糖尿病的令人兴奋的新方法。迄今为止,尚无具有羧基的DPP-4化学型已进入临床试验。从发现结构新颖的喹啉衍生物1出发,我们设计了含有羧基的新型吡啶衍生物。在我们的设计中,羧基与催化区域周围的目标氨基酸残基相互作用,从而增加了抑制活性。经过进一步优化后,我们确定了[5-(氨基甲基)-6-(2,2-二甲基丙基)-2-乙基-4-(4-甲基苯基)吡啶-3-基]乙酸的水合物(30c)作为有效且选择性的DPP-4抑制剂。通过X射线共晶结构分析确认了与关键活性位点残基的所需相互作用,例如与Arg125的盐桥相互作用。此外,化合物30c表现出所需的临床前安全性,编码为TAK-100。

    An electrochemical oxidative cross-coupling reaction between 2.5-substituted-pyrazolin-5-ones and ammonium thiocyanate has been developed, which resulted in a series of unprecedented cross-coupling products under metal catalyst-, exogenous-oxidant-, and exogenous-electrolyte-free conditions. It is worth noting that since the resulting cross-coupling products are nearly insoluble in MeCN, the pure product
