  • Antiviral activity of benzimidazole derivatives. III. Novel anti-CVB-5, anti-RSV and anti-Sb-1 agents

    A library of eighty-six assorted benzimidazole derivatives was screened for antiviral activity against a panel of ten RNA and DNA viruses. Fifty-two of them displayed different levels of activity against one or more viruses, among which CVB-5, RSV, BVDV and Sb-1 were the most frequently affected. In particular, fourteen compounds exhibited an EC50 in the range 9–17 μM (SI from 6 to >11) versus CVB-5
    筛选了八十六种各种苯并咪唑衍生物的文库对十种RNA和DNA病毒的抗病毒活性。 其中有52个针对一种或多种病毒表现出不同水平的活性,其中CVB-5,RSV,BVDV和Sb-1受感染最频繁。特别是,与CVB-5相比,十四种化合物的EC 50为9–17μM(SI为6至> 11),七种化合物的EC 50为5–15μM(SI为6.7至⩾20) )对抗RSV,因此所产生的效果与相应的参考药物(NM108和利巴韦林)相当或更高。这些化合物大多数衍生自2-苄基苯并咪唑,也衍生自其他分子支架[例如1-苯基苯并咪唑(2),2-三氟甲基苯并咪唑(69),二氢吡啶并[3',2':4,5]咪唑[1,2- a ] [1,4]苯并二氮杂-5-酮(3),二苯并[ c ^,ë ]苯并咪唑[1,2一]氮杂(22),和2-(四氢-吡喃-2-基)苯并咪唑(81,82和86)]都与活动的针对这些有趣水平或其他病毒(BVDV,Sb-

    日期:2015.6.15
    A highly regio‐ and stereoselective synthesis of 3,3‐disubstituted phthalides from aryl carboxylic acids and allenes using a rhodium(III) catalyst has been demonstrated. The reaction features broad functional group tolerance and provides a simple and straightforward route to the synthesis of various 3‐vinyl‐substituted phthalides. Furthermore, the catalytic reaction can also be applied to the synthesis
    已证明使用铑(III)催化剂可从芳基羧酸和丙二烯高度区域和立体选择性地合成3,3-二取代的邻苯二甲酸酯。该反应具有宽泛的官能团耐受性,并提供了简单而直接的途径来合成各种3-乙烯基取代的邻苯二甲酸酯。此外,该催化反应还可以用于由α,β-不饱和羧酸和丙二烯合成具有生物活性的5-乙烯基取代的2-呋喃酮。反应进行通过羧酸盐助邻-C  ħ活化和[4 + 1]环。初步的力学研究表明,CH裂解是决定速率的步骤。
  • Substrate selectivity of an isolated enoyl reductase catalytic domain from an iterative highly reducing fungal polyketide synthase reveals key components of programming
    作者:Douglas M. Roberts、Christoph Bartel、Alan Scott、David Ivison、Thomas J. Simpson、Russell J. Cox
    DOI:10.1039/c6sc03496a
    日期:——
    A cis-acting enoyl reductase (ER) catalytic domain was isolated from a fungal highly reducing iterative polyketide synthase (HR-iPKS) for the first time and studied in vitro. The ER from the squalestatin tetraketide synthase forms a discrete dimeric protein in solution. The ER shows broad substrate selectivity, reducing enoyl species including both natural and unnatural substrates. Pantetheine-bound
    首次从真菌高还原性重复聚酮合酶(HR-iPKS)中分离出顺式烯酰还原酶(ER)催化结构域并进行体外研究。来自角鲨他汀四酮化合物合酶的 ER 在溶液中形成离散的二聚体蛋白质。ER 显示出广泛的底物选择性,可减少烯酰基物质,包括天然和非天然底物。泛硫氨酸结合底物硫醇酯的反应速度比相应的 SNAC 硫醇酯快得多。非天然底物包括Z-烯烃、2-乙基烯烃和五肽。底物的甲基化改变了 ER 的活性,使得 2,4-二甲基辛-2-烯酰基底物适合活性位点但不能被还原。开发了一种新的基于 NMR 的测定法,用于直接观察 NADPH 辅因子 4' 位置以及底物 C-2 和 C-3 位置的立体化学偏好。该测定表明,真菌 iPKS ER 催化的反应在立体化学上与脊椎动物 FAS (vFAS) 在辅因子 4' 位和底物 3 位的反应相同,但完整 SQTKS 所表现出的高立体选择性消失,导致在2 位对分离的 ER 没有选择性。ER
  • Transfer-hydrogenation process
    申请人:Eastman Chemical Company
    公开号:US09988329B1
    公开(公告)日:2018-06-05
    A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an α,β-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is α,β-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C2-C4) feedstocks instead of hydrogen (H2).
    制备羰基化合物和醇化合物的转移氢化过程包括以下步骤:(a)在第一反应区域中,在存在转移氢化催化剂的条件下,将第一羰基化合物与第一醇化合物接触,以有效形成第二羰基化合物和第二醇化合物,(b)在步骤(a)期间从第一反应区域中去除第二羰基化合物。第一羰基化合物是饱和醛或酮,或α,β-不饱和醛或酮。第一醇化合物是一级或二级醇。第二醇化合物是α,β-饱和的。转移氢化催化剂包括8到11族金属。这个过程对于利用低级醇(C2-C4)原料而不是氢气(H2)来制备更高价值的醇,如丁醇或2-乙基己醇,是有用的。
