    苯并吡喃衍生物作为KATP通道开放剂的设计,合成及生物学评价
    摘要:
    为了完成SAR并发现新的有效PCO和选择性PCO,对克罗马卡林的C-4和C-2替代品进行了一些更改。合成并评价了一系列与cromakalim结构相关的4-氨基酸取代的-2,2-二烷基苯并二氢吡喃,作为ATP敏感的钾通道开放剂(8a-1)。初步生物学测试表明,这些化合物对KCl收缩的大鼠主动脉条显示出对轻度松弛活性的作用。化合物8b(IC50 =0.25μM),8f(IC50 =6.44μM)和8j(IC50 =8.65μM)表现出值得称赞的钾通道开放活性。除了抗高血压外,这些化合物还可被视为进一步开发心肌抗缺血药物的主要候选药物。

    Identification of 3-hydroxy-4[3,4-dihydro-3-oxo-2H-1,4-benzoxazin-4-yl]-2,2-dimethyldihydro-2H-benzopyran derivatives as potassium channel activators and anti-inflammatory agents
    摘要:
    The present study described the design, synthesis and identification of 3-hydroxy-4[3,4-dihydro-3-oxo-2H-1,4-benzoxazin-4-yl]-2,2-dimethyldihydro-2H-benzopyran derivatives. Their biological activity was tested for K-ATP channel opener as antihypertensives, COX-1 and COX-2 activity. The results were compared with the activity of cromakalim, ibuprofen and celecoxib. The study aimed at exploring the influence of introduction of a benzoxazine substituent at position 6 of various derivatives of benzopyrans in order to improve biological activity. Several compounds were found to be equipotent or even more potent than cromakalim. Out of these nitro-substituted benzopyrans, nitro substitution at benzoxazino group possessed potent antihypertensive activity in the R/S isomers. With amino derivatives, activity remains constant when compared with standard cromakalim. Similarly, compounds 17b, 17c, 17e and 17h have exhibited around 40 % inhibition of COX-1 as compared to the inhibition of COX-2. Only two compounds 17g and 17i exhibited effective inhibition more than 50 % of COX-2 compared with the inhibition of COX-1 at a concentration of 0.3 mg/ml.

  • Iron‐Catalyzed Wacker‐type Oxidation of Olefins at Room Temperature with 1,3‐Diketones or Neocuproine as Ligands**

    Herein, we describe a convenient and general method for the oxidation of olefins to ketones using either tris(dibenzoylmethanato)iron(III) [Fe(dbm)3] or a combination of iron(II) chloride and neocuproine (2,9-dimethyl-1,10-phenanthroline) as catalysts and phenylsilane (PhSiH3) as additive. All reactions proceed efficiently at room temperature using air as sole oxidant. This transformation has been

    oxidation of olefins into ketones. The reaction is catalyzed by the hexadecafluorinated iron–phthalocyanine complex FePcF16 with stoichiometric amounts of triethylsilane as an additive under oxygen atmosphere to give ketones in good to high yields with excellent chemoselectivity and functional group tolerance. Ketone formation proceeds in up to 95 % yield and with 100 % regioselectivity while the corresponding

The removal of the 3-hydroxy function (----17a) does not significantly reduce the activity.

    描述了4-(1,2-二氢-2-氧代-1-吡啶基)-2H-1-苯并吡喃-3-醇的合成和降压活性。未取代的吡啶酮加合物铅化合物7e具有高活性,吡啶酮环上的取代基导致活性降低。为了获得最佳活性,必须在C-6位上强烈吸电子的取代基。当2-吡啶酮环被其他杂环如4-吡啶酮,嘧啶酮,哒嗪酮,吡嗪酮和1,4-丁烷磺胺取代时,活性得以维持。3-羟基官能团(---- 17a)的去除不会显着降低活性。从苯并二氢吡喃醇中除去水会导致苯并二氢吡喃酮的形成,这是已知最有效的降压药之一。各种取代基,尤其是杂环C-6取代基的影响,以4-(2-氧代-1-吡咯烷基)色满-3-醇系列进行了研究。铬醇在3-羟基处被短链酸酯化,保持其活性。色烯双键的环氧化也产生活性化合物。环氧化物22的重排产生3-酮化合物23和烯醇衍生物25。酮23a的还原产生顺式-苯并二氢吡喃醇7ab及其反式异构体7e。在自发性高血压大鼠中以1 mg / kg

    study is an attempt to characterize the impact of the nature of substituents introduced at the 4‐ and 6‐positions of 2,2‐dimethylchromans on their capacities to inhibit insulin release from pancreatic β‐cells or to relax vascular smooth muscle cells, both biological responses that are supposed to reflect interaction with specific ion channels.

    据报道4,6-二取代的2,2-二甲基苯并二氢吡喃是主要针对ATP敏感钾通道的药理活性化合物。本研究旨在描述在2,2-二甲基苯并吡喃的4和6位上引入的取代基的性质对其抑制胰岛β细胞释放胰岛素或舒张血管平滑肌细胞的能力的影响,这两种生物反应都应该反映与特定离子通道的相互作用。从4-氨基-2,2-二甲基苯并吡喃的核心结构中,在4-位(氨基,甲酰胺基,乙酰胺基,芳基脲基/硫脲基)和6-位(氨基,甲酰胺,乙酰胺,烷氧基羰基氨基)导致对胰岛素释放过程的抑制作用逐步扩大,并且在较小程度上导致血管舒张活性降低。此外,2,2-二甲基苯并二氢吡喃化合物的右旋对映异构体29比左旋对应物对抑制胰岛素分泌过程更有效。然而,另外的药理研究表明,11和15的肌肉松弛药活性是由直接的Ca 2+进入封锁引起的。
