for in vitro antimicrobial activity a new series of hydrazide-hydrazones obtained from 5-nitrofuran-2-carboxylic acid. New compounds were identified and characterized by spectral methods (1 H NMR and 13 C NMR). All tested hydrazide-hydrazones proved to be promising antimicrobialagents. Antimicrobial activity and antifungal activity of new derivatives of 5-nitrofuran-2-carboxylic acid were revealed
在这项研究中,我们合成并评估了由5-硝基呋喃-2-羧酸制得的一系列新的酰肼-azo类化合物的体外抗菌活性。通过光谱方法(1 H NMR和13 C NMR)鉴定并表征了新化合物。所有测试过的酰肼-均被证明是有前途的抗菌剂。在许多情况下,发现5-硝基呋喃-2-羧酸新衍生物的抗菌活性和抗真菌活性高于参考物质(硝基呋喃妥因,头孢呋辛和氨苄青霉素)的活性。

Various 5-nitro-2-furoic acid hydrazones were synthesized and evaluated for in vitro activities against log and starved phase culture of two mycobacterial species and Mycobacterium tuberculosis (MTB) isocitrate lyase (ICL) enzyme inhibition studies. Among twenty one compounds, 5-nitro-N'-[(5-nitro-2-furyl) methylidene]-2-furohydrazide (4o) was found to be the most active compound in vitro with MICs of 2.65 and 10.64 mu M against log-and starved-phase culture of MTB. Compound 4o also showed good enzyme inhibition of MTB ICL at 10 mu M. The docking studies also confirmed the binding potential of the compounds at the ICL active site. (C) 2010 Elsevier Ltd.
