determined by X-ray diffraction. In addition, the in vitro ability of compounds (1)–(4) to inhibit the growth of Leishmania infantum has been evaluated. Comparisons of the redox potential of the compounds and leishmanicidal activity indicate that the presence of the electroactive nitro group is important for the biological activity. The inhibition activity of compound (3) is comparable to that of the reference
摘要 在本文中,我们报道了四种新型硝基芳香族化合物 2-6-nitrobenzo[1,3]dioxol-5-(methyleneamino)}benzoic acid (1), 2-[5-(2-硝基苯基)呋喃-2-基]亚甲基-氨基}苯甲酸 (2), 2-(6-nitrobenzo[1,3]dioxol-5-yl)methylene}hydrazinecarboxamide (3) 和 2-[5-( 2-硝基苯基)呋喃-2-基]亚甲基}肼甲酰胺(4)。化合物(1)-(4)已通过红外光谱和核磁共振光谱验证,(1)、(2)和(4)的结构已通过X射线衍射确定。此外,还评估了化合物 (1)-(4) 抑制婴儿利什曼原虫生长的体外能力。化合物的氧化还原电位和利什曼原虫活性的比较表明电活性硝基的存在对生物活性很重要。化合物(3)的抑制活性与参考药物SbCl 3 的抑制活性相当。考虑到SbCl3在耐
