名称 | β-Caryophyllene |
描述 | β-Caryophyllene ((-)-(E)-Caryophyllene) acts as an CB2 receptor agonist. |
细胞实验 | Stock solution (10 mM) of β-Caryophyllene is prepared using DMSO. Further, various concentrations (3 to 100 μM) of β-Caryophyllene are prepared by serially diluting the stock with respective culture medium.Panel of human cancer cells such as, pancreatic (PANC-1), colorectal (HCT-116 and HT-29), invasive squamous cell carcinoma (ME-180), leukemia (K562), hormone sensitive and invasive breast cancer cell line (MCF-7), and prostatic (PC3) adenocarcinoma cell lines are used. Cells are incubated in a humidified CO2 incubator at 37°C supplied with 5% CO2. Inhibitory effect of β-Caryophyllene on proliferation of the cell lines is tested using the MTT assay. The selectivity index (SI) for the cytotoxicity of β-Caryophyllene is calculated using the ratio of IC50 of β-Caryophyllene on a normal cell line (NIH-3T3) to the IC50 of β-Caryophyllene on cancer cell lines. They are for reference only. |
动物实验 | β-Caryophyllene is initially dissolved in dimethyl sulfoxide and further diluted (2%) in sterile phosphate-buffered saline (PBS) with 10% Cremophor EL (poluoxyl-35 hydrogenated castor oil).Male double transgenic APP/PS1 mice and wild-type littermates are used. The mice are group housed (3 to 5 animals/cage) with a 12:12-hour light/dark cycle and ad libitum access to food and water. In this experiment, animals are orally treated by gavage with 16, 48, or 144 mg/kg of β-Caryophyllene every morning for 10 weeks starting at the age of 7 months. All vehicle solutions are used for the respective control animal treatments and the Morris water maze test is performed. They are for reference only. |
体外活性 | β-Caryophyllene对三种测试癌细胞系(分别为HCT 116(结肠癌,IC50=19μM)、PANC-1(胰腺癌,IC50=27μM)、HT29(结肠癌,IC50=63μM)细胞)表现出选择性的抗增殖效应,而对ME-180、PC3、K562和MCF-7细胞表现出中等或较差的细胞毒性效果。结果表明,β-Caryophyllene对结直肠癌细胞(HCT 116)具有更高的选择性,选择性指数(SI)=27.9,其次是PANC-1和HT 29细胞,选择性指数分别为19.6和8。在24小时治疗后,β-Caryophyllene对HCT 116细胞的凋亡指数估计为64±0.04。10μM浓度的β-Caryophyllene在6小时治疗后导致显著的细胞核凝缩。β-Caryophyllene对HCT 116细胞迁移的抑制作用表现出剂量和时间依赖性。 |
体内活性 | 在测试期间,使用不同剂量的β-Caryophyllene对游泳速度没有影响。通过口服β-Caryophyllene能够在大致剂量依赖的方式下,改善在转基因小鼠中β-淀粉样蛋白沉积的增加,两个较高剂量在修改β-淀粉样蛋白负担方面展现出几乎相同的效果。与接受载体处理的小鼠大脑相比,接受不同剂量的β-Caryophyllene处理的小鼠大脑中激活的星形胶质细胞数量更高。β-Caryophyllene有效降低了在接受载体处理的APP/PS1小鼠中发现的COX-2蛋白水平的增强。接受β-Caryophyllene处理的动物展示出比接受载体处理的动物更高的物体识别指数[t(14)=4.204, P<0.05]。在测试试验中,物体探索的总时间在接受β-Caryophyllene处理的动物和接受载体处理的动物之间没有显著差异(t(14)=0.5874, P>0.05)。β-Caryophyllene处理不会显著改变这些由癫痫引起的神经化学变化。 |
