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. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
