  Synthesis and antibacterial activity of novel 4″-O-benzimidazolyl clarithromycin derivatives

  摘要：

  Novel 4 ''-O-benzimidazolyl clarithromycin derivatives were designed, synthesized and evaluated for their in vitro antibacterial activities. These benzimidazolyl derivatives exhibited excellent activity against erythromycin-susceptible strains better than the references, and some of them showed greatly improved activity against erythromycin-resistant strains. Compounds 16 and 17, which have the terminal 2-(4-methylphenyl)benzimidazolyl and 2-(2-methoxyphenyl)benzimidazolyl groups on the C-4 '' bishydrazide side chains, were the most active against erythromycin-resistant Staphylococcus pneumoniae expressing the erm gene and the me! gene. In addition, compound 17 exhibited the highest activity against erythromycin-susceptible S. pneumoniae ATCC49619 and Staphylococcus aureus ATCC25923 as well. It is worth noting that the 4 ''-O-(2-aryl)benzimidazolyl derivatives show higher activity against erythromycin-susceptible and erythromycin-resistant strains than the 4 ''-O-(2-alkyl) benzimidazolyl derivatives.

  Novel Clarithromycin Analogs with C-4” 2-arylbenzimidazolyl Bishydrazide Side Chain: Synthesis and Antibacterial Evaluation

  摘要：

  一系列新型的克拉霉素4”-O-2-芳基苯并咪唑衍生物被合成并评估。这些4”-O-2-芳基苯并咪唑衍生物对红霉素敏感菌株显示出优异的活性，并且相较于参考药物，对红霉素耐药菌株的活性显著提高。特别是化合物7c，其在C-4”双酰肼侧链上带有末端的2-（2-甲氧基苯基）苯并咪唑基团，不仅对红霉素敏感的肺炎链球菌ATCC49619和金黄色葡萄球菌ATCC25923表现出最强的活性，效能分别是母体克拉霉素的4倍和4倍，而且对表达mef基因和erm基因的红霉素耐药肺炎链球菌的活性也是最高的，分别是克拉霉素或阿奇霉素的133倍和32倍。

  A series of novel 4” -O-2-arylbenzimidazolyl derivatives of clarithromycin were synthesized and evaluated. These 4” -O-2-arylbenzimidazolyl derivatives demonstrated excellent activity against erythromycin-susceptible strains and showed remarkably improved activity against erythromycin-resistant strains compared with the references. In particular, compound 7c, which possesses the terminal 2-(2-methoxyphenyl)benzimidazolyl group on the C-4” bishydrazide side chain, not only presented the most potent activity against erythromycin-susceptible Streptococcus pneumoniae ATCC49619 and Staphylococcus aureus ATCC25923, exhibiting 4-fold and 4-fold higher efficacy than the parent clarithromycin, but also displayed the highest activity against erythromycin-resistant Streptococcus pneumoniae expressing the mef gene and the erm gene, which was 133-fold and 32-fold better than clarithromycin or azithromycin, respectively.
