reaction between 5-nitro-2furancarbohydrazone acid and 1,4-benzoquinone leading to mono- and bisamidrazones (I, II). Taking into account that acetylation of similar amidrazones was known to increase their activity [3], we have also attempted to synthesize the acetyl derivatives of compound I and II. However, we failed to obtain the target compounds, because both systems featured detachment of the benzoquinone
硝基呋喃系列药物的抗菌性能可与许多抗生素相媲美。此外,在某些情况下,前一种药物对抗生素抗性形式的感染剂有效 [1],并且与抗生素相比,增加了大型生物的总体免疫抗性 [2]。在继续寻找新的有效抗菌硝基呋喃化合物的过程中,我们研究了 5-硝基-2呋喃碳腙酸和 1,4-苯醌之间的反应,导致单腙和双脒腙(I,II)。考虑到已知类似脒腙的乙酰化会增加其活性 [3],我们还尝试合成化合物 I 和 II 的乙酰衍生物。然而,我们未能获得目标化合物,
