  • Development of 5-(Aryl)-3-phenyl-1H-pyrazole Derivatives as Potent Antimicrobial Compounds
    作者:B. Nagendra Chowdary、M. Umashankara、B. Dinesh、K. Girish、A. Ramesha Baba

    A series of 16 chalcone compounds were synthesized by Claisen-Schmidt condensation of various aldehydes with acetophenone using KOH as a base in ethanol. The reaction affords the desired products in good yields. Then all the 16 compounds were converted into pyrazoles by treating with hydrazine hydrate in ethanol under reflux condition. Both chalcones and pyrazoles were screened for their in vitro antibacterial (Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa) and antifungal (Aspergillus flavus, Chrysosporium keratinophilum and Candida albicans) activity. Biological activities of these compounds were compared with those of commercially available antibiotic ampicillin and antifungal agent miconazole. Pyrazoles were found to be most active and effective than corresponding chalcones for antimicrobial activity. Out of the 7 pyrazole compounds tested for antibacterial and antifungal activity, 5 compounds, 4h, 4j, 4l, 4m and 4n are turned out to be potent antimicrobial agents. Therefore these derivatives could serve as a highly promising molecules for further development.
    通过克莱森-施密特冷凝反应,合成了一系列16种查尔酮化合物,使用不同的醛与乙酰苯酮在氢氧化钾的碱性条件下于乙醇中发生反应。反应获得期望产物,产率良好。随后,所有16种化合物通过在回流条件下用水合肼处理转化为吡唑。对查尔酮和吡唑进行了体外抗菌(大肠杆菌、金黄色葡萄球菌和铜绿假单胞菌)和抗真菌(青霉菌、角质毛霉和白色念珠菌)活性筛选。这些化合物的生物活性与市售抗生素氨苄青霉素和抗真菌剂米康唑进行了比较。研究发现,吡唑在抗微生物活性方面比对应的查尔酮更为活跃和有效。在测试的7种吡唑化合物中,4h、4j、4l、4m和4n五种化合物表现出很强的抗微生物活性。因此,这些衍生物有望成为进一步开发的极具潜力的分子。

    isothiosemicarbazone, influenced the isocitrate lyase activity and caused a better inhibition at 10 μmol/L than 3‐nitropropionic acid, a standard inhibitor. The compounds were also found to act as exogenous chelators of iron, which is an obligate cofactor for many mycobacterial enzymes. Due to their low cytotoxicity, together with the activity against isocitrate lyase and the ability to sequester iron
