  Design, synthesis and biological evaluation of new 5-nitro benzimidazole derivatives as AT1 antagonists with anti-hypertension activities

  摘要：

  The design, synthesis, in vitro and in vivo evaluation of 5-nitro benzimidazole with 1,4-disubsituted or 1,5-disubsituted indole derivatives as novel angiotensin II receptor antagonist is outlined. Radioligand binding assays showed that 2-(4-((2-butyl-5-nitro-1H-benzo[d] imidazol-1-yl) methyl)-1H-indol-1-yl) benzoic acid, compound 3, displayed a high affinity for the angiotensin II type 1 receptor with IC50 value of 1.03 +/- 0.26 nM. The biological evaluation on spontaneously hypertensive rats and renal hypertensive rats showed that 3 could cause significant decrease on MBP in a dose dependent manner, whose maximal response lowered 30 mmHg of MBP at 5 mg/kg and 41 mmHg of MBP at 10 mg/kg after oral administration, and the significant antihypertensive effect lasted beyond 24 h, which is better than Losartan. Taken together 3 could be considered as an effective and durable anti-hypertension drug candidate. These encouraging results are deserved of further investigation towards its use for therapeutic benefit. (c) 2014 Elsevier Ltd. All rights reserved.

• Inhibition of rat hepatic microsomal aminopyrine N-demethylase activity by benzimidazole derivatives. Quantitative structure-activity relationships
  作者：Michael Murray、Adrian J. Ryan、Peter J. Little

  日期：1982.8

  Eight-two benzimidazole derivatives have been prepared and tested for the ability to inhibit cytochrome P-450 mediated enzyme activity (aminopyrine N-demethylase) from phenobarbitone-induced rat hepatic microsomes. Using physicochemical parameters and multiple regression analysis, we derived a quantitative structure-activity relationship (QSAR) that describes up to 87% of the data variance in terms

• Baker’s Yeast-Mediated Regioselective Reduction of 2,4-Dinitroacylanilines: Synthesis of 2-Substituted 6-Nitrobenzimidazoles

  DOI：10.1055/s-2004-837203

  日期：——

  Several 2,4-dinitro-N-acylanilines were regioselectively reduced at the C-2 position by baker's yeast in slightly basic media (pH = 7.5) to afford 2-amino-4-nitroacylanilines, which were then cyclized under acidic conditions to the corresponding 2-substituted-6-nitrobenzimidazoles. The benzimidazoles thus obtained can be employed as precursors for bioactive derivatives.

  几种 2,4-二硝基-N-酰基苯胺在微碱性介质（pH = 7.5）中被面包酵母在 C-2 位置区域选择性还原，得到 2-氨基-4-硝基酰基苯胺，然后在酸性条件下环化为相应的 2-取代-6-硝基苯并咪唑。由此获得的苯并咪唑可用作生物活性衍生物的前体。
