    Chelerythrine 抑制 BclXL-Bak BH3 肽結(jié)合,IC50 為 1.5 μM,并從 BclXL 中置換 Bax (一種含有 BH3 的蛋白質(zhì))。用 Chelerythrine 處理的哺乳動物細胞發(fā)生細胞凋亡,其特征表明線粒體通路參與[1]。Chelerythrine 處理通過選擇性抑制 p38 絲裂原活化蛋白激酶 (MAPK) 和細胞外信號調(diào)節(jié)蛋白激酶 1 和 2 (ERK1/2) 激活,抑制 LPS 誘導(dǎo)的 TNF-α 水平和 LPS 誘導(dǎo)的小鼠腹腔巨噬細胞中的 NO 產(chǎn)生。此外,Chelerythrine 對 NO 和細胞因子 TNF-α 產(chǎn)生的影響可能可以通過 p38 MAPK 和 ERK1/2 在炎癥介質(zhì)表達調(diào)節(jié)中的作用來解釋[2]。Chelerythrine 對人單核細胞白血病細胞具有細胞毒作用,LD50 值為 3.46 μM。LPS 刺激兩小時后,受血根堿和 Chelerythrine 影響的細胞顯著降低 CCL-2 表達 3.5 倍和 1.9 倍[3]。Chelerythrine chloride 以劑量依賴的方式顯著增強 ERK1/2 的磷酸化。此外,chelerythrine chloride 可抑制 p38 的磷酸化[4]。

    Cell Assay
    [1]

    Cell viability is evaluated via MTT assay. Cells (2×103?HEK-293 cells/well and 3×103?SW-839 cells/well) in 100 μL medium are seeded into 96-well plates, and incubated for 12 h. Next, the medium in each well is replaced with medium containing various concentrations of Chelerythrine Chloride, and the cells are incubated at 37°C for an additional 24 and 48 h. Subsequently, 20 μL MTT (5 mg/mL) is added to each well. Following an additional incubation at 37°C for 4 h, the supernatant is removed, and 100 μL DMSO is added to each well. The absorbance values (read at 540 nm) are determined using the iMark? Microplate Absorbance Reader. The data are analyzed using Microplate Manager software (ver. 6.3; 1689520).

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [1]

    A total of 5×106 SW-839 cells are mixed with Matrigel?, and injected subcutaneously into the flanks of 14 5-week-old male BALB/c nude mice. The mice are maintained in 18×30-cm cages containing three mice each, at a temperature of 22°C using a 12 h light/dark cycle. Food and water is available ad libitum. The mice are randomLy divided into two groups (n=7). As previously described, the mice are administrated with chelerythrine chloride at a dose of 5 mg/kg/day via intraperitoneal injection for 5 weeks, with the first injection of chelerythrine chlorideurring 24 h after injection with the SW-839 cells. The control mice are administered with the same volume of PBS containing 1% DMSO. The volume and weight of the mouse tumors are measured once a week. All the mice are sacrificed 36 days subsequent to inoculation of the cancer cells, when the tumors are resected.

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
