背景说明 |
Fisetin是一种黄酮醇,是有效的Sirtuin活化化合物,可以调节Sirtuin。具有抗氧化,抗癌,神经保护等多种生理活性。 |
生物活性 |
Fisetin is a natural flavonol found in many fruits and vegetables with various benefits, such as antioxidant, anticancer, neuroprotection effects.[1-2] |
In Vitro |
Fisetin 抑制脂质积累并抑制 3T3-L1 细胞中 PPARγ 的表达。Fisetin 抑制前脂肪细胞分化的早期阶段,并诱导 Sirt1 的表达。Fisetin 促进 Sirt1 介导的 PPARγ 和 FoxO1 去乙酰化,增强 Sirt1 与 PPARγ 启动子的结合,从而抑制 PPARγ 转录活性,从而抑制脂肪形成[1]。Fisetin 结合微管蛋白并稳定微管,其结合特性远优于紫杉醇。Fisetin 处理人前列腺癌细胞导致微管相关蛋白 (MAP)-2 和-4 的强烈上调。Fisetin 显著抑制 PCa 细胞增殖、迁移和侵袭。Nudc 是一种与调节微管动力学的微管运动动力蛋白/动力蛋白复合物相关的蛋白质,被 Fisetin 处理抑制[2]。 |
In Vivo |
对暴露于 UVB 的小鼠进行 Fisetin 处理可减少增生并减少炎症细胞的浸润。Fisetin 处理还可以降低炎症介质,例如 COX-2、PGE2 及其受体 (EP1-EP4) 和 MPO 活性。此外,Fisetin 可降低暴露于 UVB 的皮肤中炎性细胞因子 TNFα、IL-1β 和 IL-6 的水平。Fisetin 处理还可以减少细胞增殖标志物以及 DNA 损伤,p53 和 p21 蛋白的表达增加就证明了这一点[3]。 |
细胞实验 |
3T3-L1 cells are transfected with reporter vector, and expression plasmids using TransIT-LT1. After 24 h, media is replaced with viral supernatant. After 15-18 h of infection, media is replaced with DMI, 0.1 μM troglitazone and Fisetin (50 μM). Cells are lysed using cell culture lysis buffer two days after addition of differentiation stimulus. Luciferase activity is determined using an analytical luminescence luminometer[1]. |
动物实验 |
Mice: The mice are divided into six groups of eight animals each. The mice in the first group are topically treated with 0.2 mL acetone and used as vehicle control. The mice in the second and third groups receive topical treatment of Fisetin 250 nmol/0.2 mL acetone/mouse and 500 nmol/0.2 mL acetone/mouse respectively on their dorsal skin and serves as agent controls. The mice in the fourth, fifth and sixth groups are exposed to UVB. The mice in the fourth group receive a topical application of 0.2 mL acetone after 15 min of UVB exposure designated as vehicle control. The mice in the fifth and sixth groups are treated with topical application of Fisetin 250 nmol/0.2 mL acetone/mouse and 500 nmol/0.2 mL acetone/mouse respectively on to their dorsal skin after 15 min of UVB exposure[3]. |
