生物活性
Kaempferitrin 是一种天然黄酮苷类化合物,具有镇痛、消炎、抗糖尿病、抗肿瘤和化疗的作用,同时可激活胰岛素 (insulin) 信号传导。
体外研究
Kaempferitrin activates insulin signaling pathway. Kaempferitrin causes survival rates higher than 90% at 1-20 μM in matured 3T3-L1 adipocyte, and the survival rates decline rapidly at 25 and 50 μM. Kaempferitrin (15 μM) increases insulin receptor beta tyrosine phosphorylation and tyrosine phosphorylation of the insulin receptor substrate 1, and such effects are similar to that of 10 nM insulin. Kaempferitrin (15 μM) also stimulates akt phosphorylation on ser473, and the stimulation can be blocked by a PI3-K inhibitor wortmannin. Kaempferitrin potently exerts the translocation of GLUT4 to the membrane of adipocytes at 15 μM, and this is suppressed by wortmannin. In addition, Kaempferitrin increases the total levels of Glu4 protein in differentiated cells and secreted adiponectin in mature 3T3-L1 adipocytes. Kaempferitrin is cytotoxic to human cancer cells such as HeLa and MDA-MB231 cells, with IC 50 s of 45 ± 2.6 and 65 ± 2.6 μM, and shows low toxic effects on non-tumorigenic cells. Kaempferitrin (45 μM) induces apoptosis of HeLa cells after treatment for 24 and 48 h, and causes reactive oxygen species (ROS) generation in HeLa cells. Furthermore, Kaempferitrin (45 μM) exerts G1 arrest, causes the expression of proteins associated with intrinsic pathway of apoptosis and activates caspase 3 in HeLa cells.
体内研究
Kaempferitrin (2.5, 10 and 25 mg/kg, i.p.) markedly suppresses the growth of tumor by 40%, 87% and 97%, and decreases tumor weight by 37%, 81% and 95%, respectively in nu/nu mice bearing HeLa tumor. Kaempferitrin also inhibits cell proliferation and extends life span in mice bearing tumor.
