Product Introduction
Bioactivity


英文名: Magnesium Lithospermate B

描述: Magnesium Lithospermate B 是一种咖啡酸四聚体的衍生物，从Salviae miltiorrhizae 中提取得到。它能够抑制神经炎症并减轻神经变性。它被广泛用于心血管疾病的研究，并且可以防止葡萄糖引起的细胞内氧化损伤。

动物实验: Adult male Sprague-Dawley rats were subjected to an endovascular perforation process to produce an SAH model.?MLB was administrated intraperitoneally at 30min after SAH with a dose of 25mg/kg or 50mg/kg[1].

体外活性: magnesium lithospermate B (MLB) dose-dependently inhibited the activation of microglia and reduced neuronal apoptosis.?Western blot analysis showed that MLB decreased the expression of inflammatory cytokine TNF- and pro-apoptotic protein cleaved caspase-3.?More importantly, MLB increased the expression of SIRT1, while inhibited the acetylation of NF-B.?Furthermore, pretreatment with sirtinol (a selective inhibitor of SIRT1) reversed all the aforementioned effects of MLB after SAH[1].

体内活性: Magnesium Lithospermate B (MLB)，一种从丹参中提取的活性成分，在多种中枢神经系统损伤中表现出神经保护作用。研究表明，MLB的给药显著减轻了蛛网膜下腔出血(SAH)[1]后的脑水肿和神经功能障碍。
