Phospha–Michael-type addition reaction of tetraethyl methylene-1,1-bisphosphonate reagent to a group of Schiff bases incorporating benzothiazole moiety. The reactions proceeded under microwave irradiation, utilizing the advantages of the environment, friendly protocol such as high efficiency, short reaction time, and excellent yields. In consistency with the prospected results, the new NBP acids revealed positive properties
苯并噻唑-β取代的新抗肿瘤系列-氨基双膦酸的开发是基于苯并噻唑基序和氨基亚甲基双膦酸酯部分的预期效力以及使用计算机程序PASS 2014-1版对生物活性的预测。通过亚甲基-1,1-双膦酸四乙酯的磷化钾与一组结合苯并噻唑基团的席夫碱的磷酰-迈克尔型加成反应,以优异的产率(70-90%)获得目标化合物。该反应在微波辐射下进行,利用了环境的优点,友好的方法,如高效,短反应时间和优异的收率。与预期结果一致,新的NBP酸显示出对人乳腺和结肠肿瘤细胞系的积极特性。与阳性对照阿霉素(乳腺,GI)相比,GI 50:2.05-6.47μM)和结肠癌(COLO-205,HCT-116,HCC-2998和SW-620,GI 50:3.03-7.92μM)50:3.27–6.64μM;结肠,GI 50:4.09–8.75μM)。值得注意的是,预测结果与确定的生物学结果之间存在一致性。
