  Synthesis and inhibitory activity of benzoic acid and pyridine derivatives on influenza neuraminidase

  摘要：

  Based upon the activity and X-ray crystallographic studies of tri-substituted benzene derivatives containing carboxylic acid, acetamido and guanidine groups, we investigated the effect of the fourth substituent to fulfill the fourth pocket of neuraminidase enzyme. The groups selected as fourth substituents were hydroxymethyl, hydroxyethyl, oxime and amino. These tetra-substituted benzene derivatives were synthesized and evaluated for neuraminidase inhibitory activity. All these compounds were found to have poorer IC50 values than the tri-substituted compounds. Further, benzene ring was replaced by pyridine ring and di, tri and tetra-substituted pyridine derivatives were synthesized. The activity of the pyridine derivatives was comparable to benzene derivatives. The fourth substituent seems to disturb the binding of the other three substituents, so the activity is reduced as compared to trisubstituted benzene and pyridine derivatives. (c) 2005 Elsevier Ltd.

  瞬态保护的4-氮杂/苯并咪唑腈的六甲基锂二硅氮烷锂转化为Am及其二甲基亚砜介导的咪唑环形成

  摘要：

  三甲基甲硅烷基瞬态保护成功地允许使用六甲基二硅氮烷锂从腈中以58-88％的产率制备苯并咪唑（BI）和4-氮杂苯并咪唑（azaBI）idine。与冗长的，低产率的Pinner反应相比，该策略为制备BI / azaBI idine提供了更好的选择。在二甲基亚砜中，由芳族二胺和醛合成氮杂/苯并咪唑环的过程在10-15分钟内受到影响，而已知的方法则需要较长时间和纯化。这些方法对于基于BI / azaBI的制药行业以及开发用于扩展治疗应用的特定DNA结合剂都非常重要。

  Whole-cell high-throughput screening of the AstraZeneca compound library against the asexual blood stage of Plasmodium falciparum (Pf) led to the identification of amino imidazoles, a robust starting point for initiating a hit-to-lead medicinal chemistry effort. Structure-activity relationship studies followed by pharmacokinetics optimization resulted in the identification of 23 as an attractive lead with good oral bioavailability. Compound 23 was found to be efficacious (ED90 of 28.6 mg.kg(-1)) in the humanized P. falciparum mouse model of malaria (Pf/SCID model). Representative compounds displayed a moderate to fast killing profile that is comparable to that of chloroquine. This series demonstrates no cross-resistance against a panel of Pf strains with mutations to known antimalarial drugs, thereby suggesting a novel mechanism of action for this chemical class.

  from nitriles in 58–88% yields. This strategy offers a much better choice to prepare BI/azaBI amidines than the lengthy, low-yielding Pinner reaction. Synthesis of aza/benzimidazole rings from aromatic diamines and aldehydes was affected in dimethyl sulfoxide in 10–15 min, while known procedures require long time and purification. These methods are important for the BI/azaBI-based drug industry and
