synthesized, bearing two to six OCD3 groups, in some cases in combination with methoxy groups, and in others together with fluorine or chlorine atoms. A model ring-deuterated hexamethoxy-CUR-BF2 and its corresponding CUR compound were also synthesized from a 2,4,6-trimethoxybenzaldehyde-3,5-d2 precursor. As with their protio analogues, the deuterated compounds were found to remain exclusively in the enolic
合成了一系列氘代姜黄素(CUR),带有两个至六个OCD3基团,在某些情况下与甲氧基结合,在另一些情况下与氟或氯原子结合。还从2,4,6-三甲氧基苯甲醛-3,5-d2前体合成了模型环氘化的六甲氧基-CUR-BF2及其相应的CUR化合物。与它们的蛋白质类似物一样,发现氘代化合物仅以烯醇形式保留。这些化合物的抗增殖活性通过体外生物测定针对一组60种癌细胞系进行了研究,更具体地说,是针对人结肠直肠癌(CRC)细胞(HCT116,HT29,DLD-1,RKO,SW837和Caco2)进行的。正常结肠细胞(CCD841CoN)。通过NCI-60分析,氘代CUR-BF2加合物表现出更好的整体生长抑制作用,而对于其他CUR-BF2加合物,非氘代类似物具有更高的细胞毒性。比较集中的比较细胞活力分析的结果遵循相同的趋势,但根据细胞系有所不同。CUR-BF2加合物显示出比CURs高得多的细胞毒性。还报道了结构研
