  Synthesis and biological evaluation of some 4-functionalized-pyrazoles as antimicrobial agents

  摘要：

  1,3-Diaryl-4-formylpyrazoles 8 bearing benzenesulfonamide moiety at position-1 were synthesized as important intermediates following Vilsmeier-Haack strategy. Aldehyde moiety of 4-formylpyrazole was then converted into carboxylic acid 9, cyano 10 and carbothioamide 11 using established procedures. Out of these 4-functionalized pyrazoles, pyrazole-4-carboxylic acids 9 and carbothioamides 11 were evaluated for their in vitro antibacterial activity against four pathogenic bacterial strains namely, Staphylococcus aureus, Bacillus subtilis (Gram-positive), Escherichia coli, Pseudomonas aeruginosa (Gram-negative), and in vitro antifungal activity against two pathogenic fungal strains namely, Aspergillus niger and Aspergillus flavus. Three tested compounds, 9e, 11b and 11f exhibited moderate antibacterial activity against Gram-positive bacteria and 9g showed moderate antifungal activity against the tested fungi. However, none of the compounds showed any activity against Gram-negative bacteria. (c) 2011 Elsevier Masson SAS. All rights reserved.

  were designed, synthesized and evaluated against four human carbonic anhydrase isoforms belonging to α family comprising of two cytosolic isoforms hCA I and II as well as two transmembrane tumor associated isoforms hCA IX and XII. Starting from these derivatives that showed high potency but low selectivity in favor of tumor associated isoforms hCA IX and XII, we investigated the impact of removing the

  设计，合成和评估了新型吡唑基苯并[d]咪唑衍生物（2a-2f），并针对四种属于α家族的人碳酸酐酶同工型，其中包括两个胞质同工型hCA I和II，以及两个跨膜肿瘤相关同工型hCA IX和XII。从显示出高效力但低选择性的这些衍生物开始，支持肿瘤相关同工型hCA IX和XII，我们研究了去除磺酰胺基团的影响。因此，合成了没有磺酰胺部分的类似物3a-3f，并且生物学测定显示出作为与肿瘤相关的hCA IX和hCA XII的抑制剂的良好的活性以及优异的选择性，并且通过分子对接研究对其进行了分析。
