aflatoxin B1 biosynthesis was observed in presence of 6-NFBD. These benzimidazole derivatives also showed good anti-aflatoxigenic activity in rice, though the IC50 concentrations in rice were comparatively higher than those in YES medium. This study summarizes the most notable structure-activity relationship (SAR) of 2-(2-Furyl) benzimidazoles for anti-aflatoxigenic and anti-fungal activities. These molecules

the corresponding thioamide. The latter was oxidized with K3[Fe(CN)6] in alkaline environment to obtain 2,8-dimethyl-7-(furan-2-yl)-8H-imidazo[4,5-g][1,3]benzothiazole. Its reactions of electrophilic substitution were studied: nitration, bromination, sulfonation, formylation, acylation. The substituent is introduced exclusively in the position 5 of the furan ring.
在硫酸铜存在下,1,2-二氨基-4-硝基苯与呋喃-2-甲醛反应,得到2-(呋喃-2-基)-5(6)-硝基-1 H-苯并咪唑。其N-甲基化提供了1-甲基-5(6)-硝基异构体。用锡浓溶液还原异构体后。HCl得到纯的3-甲基-2-(呋喃-2-基)苯并咪唑-5-胺。该胺与乙酸酐的缩合导致形成N- [3-甲基-2-(呋喃-2-基)苯并咪唑-5-基]乙酰胺,其在无水吡啶中用过量的P 2 S 5处理可得到相应的硫代酰胺。后者在碱性环境下用K 3 [Fe(CN)6 ]氧化,得到2,8-二甲基-7-(呋喃-2-基)-8H-咪唑并[4,5- g ] [1,3]苯并噻唑。研究了其亲电取代反应:硝化,溴化,磺化,甲酰化,酰化。取代基仅引入呋喃环的5位。

inspired frommarinenaturalproducts (oroidin and bromoageliferin) was identified and synthesized to explore the antifouling/antifungal properties for the first time. Twelve 2-aryl benzimidazole derivatives were synthesized and evaluated for their antifouling performance against 10 strains of marine biofilm forming bacteria developed on copper panels exposed for 14 days at Dona Paula, ArabianSea, India
