    1-Amino-2-hydrazinobenzimidazole and its reactions with some carbonyl compounds
    摘要:
    1-Amino-2-hydrazinobenzimidazole was obtained for the first time by treating 1-aminobenzimidazole-2-sulfonic acid with hydrazine hydrate. This compound readily condensed with aromatic aldehydes involving both amino groups. The condensation with 2,4-pentanedione affords 1-amino-2-(3,5-dimethylpyrazol-1-yl)benzimidazole, and with alpha-ketoacids in glacial acetic acid yields mixtures of 10-acetylamino-3-R-1,2,4-triazino[4,3-a]benzimidazol-4(10H)-ones and 4-amino-2-R-1,2,4-triazino[2,3-a]benzimidazol-3(4H)-ones.

  • Prototropic equilibrium in 1(11)H-2, 3, 4, 5-tetrahydro[1, 3]diazepino[1, 2-a]benzimidazole, synthesis and pharmacological properties of its N-substituted derivatives

    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。

    diffraction (XRD). From the XRD data it is found that the complexes crystallize in the triclinic space group \(P\bar1}\) as solvates with alcohol and water molecules. In mononuclear molecules of both complexes, two trischelate ligands in mono- and dianionic forms are coordinated to the Co(III) cation. The coordination environment of the cobalt atom CoN4O2 corresponds to a distorted octahedron in both compounds
