AbstractA simple and practical protocol was developed for the synthesis of benzimidazoles. The protocol uses iminoester hydrochloride which is very useful in the reaction with 4,5-dichloro-1,2-phenylenediamine under microwave irradiation leading to the products with good yields and in short reaction times. This method can be used as a general technique for synthesizing benzimidazoles. The synthesized compounds
摘要为合成苯并咪唑开发了一种简单实用的方案。该方案使用亚氨基酯盐酸盐,其在微波辐射下与4,5-二氯-1,2-苯二胺的反应中非常有用,可得到产率高且反应时间短的产物。该方法可以用作合成苯并咪唑的通用技术。评价合成的化合物的生物学特性,例如抗脂肪酶,抗病毒和抗肿瘤活性。尽管有低毒性,但五种苯并咪唑-1-乙酸酰肼在25μg/ cm 3浓度下仍显示出轻微的抗病毒活性。取代的2-苄基苯并咪唑类药物对腺癌(CT26)和黑色素瘤(B16F10)癌细胞的活性低于10μg/ cm 3。。其中六种化合物在不同浓度下均显示出抗脂肪酶的活性。一种化合物的IC 50值为0.35μg/ cm 3,与奥利司他(0.32μg/ cm 3)具有相似的活性。 图形概要
