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。
产品描述
Lithospermate B is a natural product activates eNOS and ameliorates endothelial dysfunction in diabetes by enhancing vasodilation in addition to reducing oxidative stress, it can protecte cardiomyocytes from ischemic injury through specific inhibition of TAB1-p38 apoptosis signaling.improves renal failure.
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), a bioactive ingredient extracted from Salvia miltiorrhiza, exerts neuroprotective effects in several central nervous system insults.administration of MLB significantly attenuated brain edema and neurological deficits after SAH[1].
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].
