compound 3c, (IC50 value 6.25 μM) has shown better cytotoxicity effect against three cell lines. According to results of SAR study, it was found that 4H-pyrimido[2,1-b]benzothiazole derivatives (2e and 2f), pyrazoles (3a, 3b, 3c and 3d) benzylidenes (4d) exhibited better antioxidant activity than curcumin. A correlation of structure and activities relationship of these compounds with respect to drug
设计了一系列姜黄素衍生物/类似物,并描述了其合成的有效方法。筛选所有合成的化合物的细胞毒性并评估其抗氧化活性。已经通过MTT测定法评估了针对三种细胞系Hep-G2,HCT-116和QG-56的细胞毒性作用。结构活性关系表明,特别是化合物3c(IC50值为6.25μM)对三种细胞系表现出更好的细胞毒性作用。根据SAR研究的结果,发现4H-嘧啶并[2,1-b]苯并噻唑衍生物(2e和2f),吡唑(3a,3b,3c和3d)亚苄基(4d)具有比姜黄素更好的抗氧化活性。
