体外研究 |
异牡荆素通过抑制细胞内ROS的产生来预防LPS诱导的氧化损伤,并且还减弱H2O2对细胞活力的影响。含有LPS(2μg/ mL)的异牡荆素(0-100μg/ mL)对RAW 264.7细胞没有细胞毒性,但200μg/ mL异牡荆素显示出显着的细胞毒性。异牡荆素(25,50μg/ mL)抑制LPS诱导的TNF-α,IL-6,iNOS和COX-2水平的增加。异牡荆苷(25,50μg/ mL)也抑制RAW 264.7细胞中的IκBα磷酸化和降解,这种作用与JNK1 / 2抑制剂的作用一致[1]。 |

体内研究 |
异牡荆素(50和100mg / kg,ip)引起肺切片中较不严重的组织病理学变化,并减少LPS诱导的小鼠中的炎性细胞计数。异嗜酸蛋白(50和100 mg / kg,ip)通过降低TNF-α和IL-6产生,ROS产生,MPO和MDA含量,增加SOD和GSH,在LPS诱导的ALI小鼠中预防LPS诱导的炎症和氧化应激。水平并有效抑制iNOS和COX-2的蛋白表达[1]。异牡荆素(25,50,100mg / kg)剂量依赖性地降低小鼠中LPS / D-gal诱导的肝损伤的存活率。异牡荆素还抑制NF-κB的活化,并上调小鼠LPS / D-gal诱导的Nrf2和HO-1 [2]。 |

细胞实验 |
通过MTT测定确定细胞活力。将RAW 264.7细胞接种在96孔板(1×10 4个细胞/孔)中,并与各种浓度的异牡荆素(终浓度:0-200μg/ mL)和LPS(2μg/ mL)孵育24小时。此外,用IV(25或50μg/ mL)预处理细胞1小时,然后加入H 2 O 2(300μM)。 24小时后,将MTT(5mg / mL)加入细胞中,然后再孵育4小时[1]。 |

动物实验 |
小鼠[1]为了建立ALI模型,将小鼠随机分成6组:对照(盐水),仅异牡荆素(100 mg / kg,溶于0.5%DMSO),仅LPS(0.5 mg / kg,溶于盐水) ,LPS(0.5mg / kg)+异牡荆苷(50或100mg / kg)和LPS(0.5mg / kg)+地塞米松(Dex,5mg / kg溶于盐水中)。给予异牡荆苷或Dex(5mg / kg)异牡荆苷。在暴露于异牡荆素或Dex 1小时后,用乙醚麻醉小鼠,并鼻内(in)施用LPS以诱导肺损伤。 LPS施用12小时后,对动物实施安乐死。因此,收获支气管肺泡灌洗液(BALF)和肺组织样品以测量细胞因子水平; ROS生成; SOD,GSH,MDA和MPO活性;和COX-2,iNOS,HO-1和Nrf2蛋白的表达[1]。 |
