Several synthetic and natural naphthoquinone derivatives have been associated with antifungal activity. Candida albicans is a fungus that is known to exist in the normal human flora, but under certain conditions it can cause mild to fatal infections. Its pathogenicity has been associated with fungus conversion from cellular yeast to filamentous form Y – M . Inhibition of this process by several anilino-
几种合成的和天然的萘醌衍生物与抗真菌活性有关。 白色念珠菌 是一种已知存在于正常人类菌群中的真菌,但在某些条件下会引起轻度至致命的感染。其致病性与真菌从细胞酵母转化为丝状 Y – M有关 。为了发现结构,氧化还原性质和生物活性之间的相关性,研究了几种苯胺基,二苯胺基,苯氧基和二苯氧基-1,4-萘醌对这一过程的抑制作用。

The preparation of novel 2-(fluoroanilino)-1,4-naphthoquinones is presented. It takes place under mild conditions by reacting the corresponding fluoroaniline and 1,4-naphthoquinone in the presence of a Lewis acid catalyst with strong oxidation properties such as CeCl3·7H2O. This preparation was also investigated under microwave irradiation. All 1,4-naphthoquinone derivatives were characterized by UV–Vis
介绍了新型2-(氟苯胺基)-1,4-萘醌的制备。它是在温和的条件下,通过使相应的氟苯胺和1,4-萘醌在具有强氧化性能的路易斯酸催化剂(例如CeCl 3 ·7H 2 O)存在下反应来进行的。该制备方法也在微波辐射下进行了研究。所有1,4-萘醌衍生物均通过UV-Vis,IR,1 H和19 F NMR,MS和循环伏安法进行表征,以研究含氟取代基对其电子性能的影响。
