    摘要:
    制备了一系列新颖的6,7-二取代的反式3,4-二氢-2,2-二甲基-4-吡咯烷基-(或哌啶子基)-2H-1-苯并吡喃-3-醇,并在其中测试了降压活性有意识的自发性高血压大鼠(SHR),并与某些单取代类似物进行了比较。通过在C(7)处引入一个乙酰氨基或氨基,可以增强6个单取代化合物的有效降压活性,而在一个C(7)处引入一个氨基(而不是一个乙酰氨基),可以增强7-硝基取代的化合物的降血压活性。 C(6)。在反式-4-吡咯烷基-或-4-哌啶子基-2,2-二甲基-2H中6-硝基或6-氰基与7-(乙酰氨基)或7-氨基和6-氨基与7-硝基的组合-1-苯并吡喃酚在SHR中对肼屈嗪和钙拮抗剂硝苯地平具有优异的降压活性。这些化合物的合成途径涉及将2H-1-苯并吡喃转化为用吡咯烷或哌啶处理的溴代醇。当以6-氰基-7-[[(三氟乙酰基)氨基] -2,2-二甲基苯并吡喃]为起始原料时,完成了6-氰基-7-氨基类似物的制备。

  • SYNTHESIS OF AVRAINVILLAMIDE, STREPHACIDIN B, AND ANALOGUES THEREOF

    公开(公告)日:2009-06-04
    The syntheses of the natural products, avrainvillamide and stephacidin B, are provided. The α,β-unsaturated nitrone functionality of avrainvillamide and its 3-alkylidene-3H-indole 1-oxide core is shown to covalently and reversibly bond to heteroatom-based nucleophiles. This capability may allow these molecules to bind active site nucleophiles and may provide the basis for designing potent and selective enzyme inhibitors. Both avrainvillamide and its dimer stephacidin B have been reported to exhibit antiproliferative activity, and avrainvillamide has been reported to exhibit antimicrobial activity against multi-drug resistant bacteria. Avrainvillamide has been found to target cytoskeleton-linking membrane protein (CLIMP-63) thereby preventing cells from undergoing mitosis. The invention provides syntheses of these natural products as well as analogs of these natural products and their functional cores. The compounds of the invention may be used in the treatment of diseases such as cancer, autoimmune diseases, and bacterial infection.
    本文提供了天然产物avrinvillamide和stephacidin B的合成方法。avrinvillamide的α,β-不饱和亚硝基功能和其3-烷基亚甲基-3H-吲哚1-氧化物核心被证明可以共价可逆地结合到基于杂原子的亲核试剂上。这种能力可能使这些分子能够结合到活性位点的亲核试剂,并为设计有效和选择性的酶抑制剂提供基础。avrinvillamide和其二聚体stephacidin B均已报道具有抗增殖活性,avrinvillamide也已报道具有对多药耐药细菌的抗菌活性。发现avrinvillamide的靶点是细胞骨架连接膜蛋白(CLIMP-63),从而防止细胞进行有丝分裂。本发明提供了这些天然产物以及它们的类似物和功能核心的合成方法。本发明的化合物可以用于治疗癌症、自身免疫性疾病和细菌感染等疾病。
