Nitrofurylbenzimidazoles having general formula (I)
wherein R is hydrogen; * straight or branched C1-C12 alkyl; halogen; nitro group; or halogen-substituted C1-C4 lower alkyl are obtained with high yields by condensing an o-phenylendiamine having general formula (II)
wherein R has the above-identified meaning, with 5-nitro-2- furaldehyde in the presence of a ferricyanide of the alkaline or alkaline-earth metals.
Nitrofurylbenzimidazoles (I) are endowed with potent antimycotic, antibacterial and antitubercular activities and are suitable for being compounded into pharmaceutical compositions administrable via the systemic route.
具有通式(I)(其中 R 为氢;* 直链或支链 C1-C12 烷基;卤素;硝基;或卤素取代的 C1-C4 低级烷基)的硝基苯并咪唑,是在碱金属或碱土金属的三氯化铁存在下,通过将具有通式(II)(其中 R 具有上述含义)的邻苯基苯二胺与 5-硝基-2-呋喃甲醛缩合而得到的,产量很高。 硝基苯并咪唑(I)具有很强的抗霉菌、抗菌和抗结核活性,适合复配成可通过全身途径给药的药物组合物。
