Isovitexin

一种C-糖基化黄酮；在无细胞测定中清除DPPH自由基（IC50=370µg/ml）；在50和100µg/ml浓度下对HepG2、MCF-7和HCT116癌细胞有细胞毒性；在50µg/ml浓度下抑制LPS诱导的TNF-α和IL-6产生并降低RAW 264.7细胞中的iNOS和COX-2水平；在200µg/ml浓度下降低PC12细胞中Aβ(25-35)诱导的细胞毒性。A C-glycosylated flavone; scavenges DPPH radicals in a cell-free assay (IC50 = 370 µg/ml); cytotoxic to HepG2, MCF-7, and HCT116 cancer cells at 50 and 100 µg/ml; inhibits LPS-induced production of TNF-α and IL-6 and decreases iNOS and COX-2 levels in RAW 264.7 cells at 50 µg/ml; reduces cytotoxicity induced by Aβ (25-35) in PC12 cells at 200 µg/ml.分子式C21H20O10分子量432.4O=C1C2=C(O)C([C@H]3[C@H](O)[C@@H](O)[C@H](O)[C@@H](CO)O3)=C(O)C=C2OC(C4=CC=C(O)C=C4)=C1
