    摘要:
    2型糖尿病是一种复杂的代谢疾病,需要多药理学方法才能有效治疗。已设计并合成了15种新的三环苯并咪唑衍生物的组合库,以结合通常在变构AMPK激活剂和AT 1受体拮抗剂中发现的片段。发现2'-氰基联苯用作AMPK活化活性的药效基团,其也随着外部氢化循环的扩展而增加。同样,显着的抗血小板活性是所研究化合物的特征。衍生物之一被确定为具有反应性二羰基清除活性的高级蛋白质糖基化终产物形成的有效抑制剂。两个亚微摩尔AMPK激活剂2b和3b防止小鼠巨噬细胞的炎症激活。这些结果以及良好的水溶性和合成可用性使稠合苯并咪唑的联苯衍生物成为开发具有多目标抗糖尿病活性的AMPK活化剂的宝贵起点。

    Based on the X-ray crystallography and 1H NMR spectroscopy data and quantum chemical studies, it was found that 1(11)H-2, 3, 4, 5-tetrahydro[1, 3]diazepino[1, 2-a]benzimidazole (1) exists almost exclusively in the 1H-prototropic form. To prepare the fixed 11H-diazepinobenzimidazole forms of 1, 1-R-2-(4-chlorobutylamino)benzimidazoles (R = Me, N=CHAr) were synthesized, which underwent thermal cyclization with the formation of a mixture of 11-Rsubstituted diazepine 1 and 1-R-2-(pyrrolidin-1-yl)benzimidazole. Alkylation of diazepine 1 in a neutral medium regioselectively gave 11-R-diazepinobenzimidazoles in high yield. Their 1-substituted isomers were obtained by carrying out this reaction in the system NaH—THF. The N(11)-derivatives of diazepinobenzimidazole 1 were found to inhibit dipeptidyl peptidase 4 (DPP-4), but less actively than a comparator drug sitagliptin. The compounds under study did not exhibit antiglycation action in vitro and virtually did not affect activity of α-glucosidase and glycogen phosphorylase. However, they are characterized by a strong antiaggregant effect, making these derivatives promising for further studies.
    基于X射线晶体学、1H NMR光谱数据和量子化学研究,发现1(11)H-2,3,4,5-四氢[1,3]二氮杂环[1,2-a]苯并咪唑(1)几乎完全以1H-质子化形式存在。为了制备固定化的11H-二氮杂环苯并咪唑形式1,合成了1-R-2-(4-氯丁胺)苯并咪唑(R=Me,N=CHAr),它们经过热环化反应,形成11-R取代的二氮杂环1和1-R-2-(吡咯烷-1-基)苯并咪唑的混合物。二氮杂环1在中性介质中的烷基化反应选择性地得到高产率的11-R-二氮杂环苯并咪唑。它们的1-取代异构体是通过在NaH-THF体系中进行此反应得到的。发现二氮杂环苯并咪唑1的N(11)衍生物抑制二肽基肽酶4(DPP-4),但活性低于对照药物西他列汀。所研究的化合物在体外未表现出抗糖基化作用,并且几乎不影响α-葡萄糖苷酶和糖原磷酸化酶的活性。然而,它们的特点是具有强大的抗聚集作用,使这些衍生物有望进一步研究。

  • Synthesis of 1(11)H-2,3,4,5-tetrahydro[1,3]diazepino[1,2-a]benzimidazole starting from benzimidazole-2-sulfonic acid. Intramolecular cyclization of 2-(δ-chlorobutylamino)benzimidazole

    The intramolecular cyclization of 2-(δ-chlorobutylamino)benzimidazole (3c) follows the unusual pathway involving the predominant attack on the exocyclic amino group rather than on the much more nucleophilic endocyclic nitrogen atom. This reaction affords 2-pyrrolidinobenzimidazole and 1(11)H-2,3,4,5-tetrahydro[1,3]diazepino[1,2-a]benzimidazole as the major product and the by-product, respectively. The cyclization can be directed exclusively toward the annulation of the diazepine ring only after the acetylation of the amino group of compound 3c. According to the quantum chemical calculations, the unusual regioselectivity of the cyclization of chloramine 3c is associated primarily with a substantially less steric strain and the higher entropy of pyrrolidine transition states compared to diazepine transition states.
    2-(δ-chlorobutylamino)benzimidazole (3c)的分子内环化采用了不寻常的途径,即主要攻击环外氨基,而不是攻击亲核性更强的环内氮原子。该反应的主要产物和副产物分别是 2-吡咯烷基苯并咪唑和 1(11)H-2,3,4,5- 四氢[1,3]二氮杂卓[1,2-a]苯并咪唑。只有在化合物 3c 的氨基发生乙酰化反应后,环化反应才能完全指向二氮杂环的环化。根据量子化学计算,氯胺 3c 环化反应的非同寻常的区域选择性主要与吡咯烷过渡态的立体应变和熵值大大低于二氮杂环庚烷过渡态有关。
