New heterocyclic derivatives of benzimidazole with germicidal activity
摘要:
Several benzimidazole derivatives have been tested in vitro for their ability to inhibit human placental aromatase activity. The results show that five out of the six compounds tested are more active in the inhibition of aromatase activity than aminoglutethimide (AG), which we chose as the reference compound and which, as an aromatase inhibitor, is currently being used in the treatment of metastatic breast cancer.

5-Fluoro-2-(5-nitrofuryl)benzimidazole (I) was synthesized from 4-fluoro-1,2-diaminobenzene and 5-nitro-2-furoic acid using ethyl polyphosphate as cyclization reagent. N-Ethyl derivative was isolated as by-product in substantial amount.
Process for preparing nitrofurylbenzimidazoles and pharmaceutical compositions having antimycotic, antibacterial and antitubercular activities containing same
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。
