生物活性

产品描述

κ-Carrageenan 是⼀种天然聚合物,主要存在于红⾊海藻中。κ-Carrageenan 是⼀种有效的药物载体,能在癌细胞中传递 姜⻩素,诱导凋亡。κ-Carrageenan 是⼀种潜在的炎症因⼦,可以放⼤现有的肠道炎症。

靶点

 

体外研究

κ-Car- Curcumin (Cur) (0-500μg/mL; 24-72 hours) effectively involves in cancer cell growth inhibition at lower concentrations of 40μg/mL.

The cytotoxicity of the Cur loaded κ-Car has a significantly high apoptotic activity in selected lung cancer cells of A549.

κ-Carrageenan (1-60μg/mL; 0.5-24 hours) enhances LPS-induced IL-8 secretion in HT-29 cells

Cell Viability Assay

Cell Line:

A549 cells

Concentration:

0-500μg/mL

Incubation Time:

24, 48 and 72 hours

Result:

The dose response effects of cells treated with Cur loaded κ-Car after incubation of 24, 48 and 72 h exhibited a significant IC50 values of 65, 50 and 40μg/mL respectively, for 24, 48, 72 h ours.

体内研究

κ-Carrageenan (1.7-41.7 mg/kg; p.o. for 1 week prior to C. freundii DBS100 treatment) can synergistically activate LPSinduced inflammatory through the Bcl10-NF-κB pathway, as indicated by its aggravation of C. freundii DBS100-induced colitis in mice.

κ-Carrageenan enhances the C. freundii DBS100-dependent induction of TLR4 and NF-κB in the intestinal mucosa of infected mice.

κ-Carrageenan aggravates the TNBS-induced intestinal inflammation, and such an effect could be associated with the oxidative stress and activation of TLR4-NF-κB and MAPK/ERK1/2 pathway

Animal Model:

Male and female NIH (s) mice

Dosage:

1.7 mg/kg, LOW; 8.3 mg/kg, MED; or 41.7 mg/kg, HIG

Administration:

Orally administered for 1 week prior to C. freundii DBS100 treatment

Result:

Enhanced the C. freundii DBS100-dependent induction of TLR4 and NF-κB in the intestinal mucosa of infected mice.
