in the 1H,3H-pyrrolo[1,2-c]thiazole ring system is essential to ensure high cytotoxicty against MCF7 breast cancer cell lines. To probe whether the absolute configuration of the lead compound might affect the anticancer activity, its enantiomer was prepared and the activity against MCF7 cells was evaluated. (3S)-6,7-Bis(hydroxymethyl)-5-methyl-3-phenyl-1H,3H-pyrrolo[1,2-c]thiazole proved to be the most
报道了6,7-双(羟甲基)-1 H,3 H-吡咯并[1,2- c ]噻唑类化合物作为抗MCF7乳腺癌细胞系的抗癌剂的合成及生物学评价。以(3 R)-6,7-双(羟甲基)-5-甲基-3-苯基-1 H,3 H-吡咯并[1,2- c ]噻唑为先导化合物的设计指导了新化合物的设计。化合物具有良好的抗MCF7乳腺癌细胞系性能(IC 50 = 1.0μM)。结构变化包括C-3处的苯基去除,3,4,5-三甲氧基苯基取代该基团,铅支架上C-5处的甲基去除以及该骨架的取代基团由苯基取代基取代。总体而言,这些研究表明,在1 H,3 H-吡咯并[1,2- c ]噻唑环系统中C-3处的苯基和C-5处的甲基的组合存在对于确保高细胞毒性至关重要对抗MCF7乳腺癌细胞系。为了探测前导化合物的绝对构型是否会影响其抗癌活性,制备了其对映异构体并评估了其对MCF7细胞的活性。(3 S)-6,7-双(羟甲基)-5-甲基-3-苯基-1H,3
