Background | Procyanidin B2 is a flavonoid with antitumor, antioxidant and other activities. |
Biological Activity | Procyanidin B2 是一种天然黄酮类物质,具有抗肿瘤,抗氧化等作用。[1-3] |
In Vitro | 原花青素B2显示对MCF-7细胞的抗增殖活性,IC50为19.21μM。然而,原花青素B2对DNA梯形成没有影响[1]。原花青素B2(0.1,1,2μM)抑制人脐静脉内皮细胞(HUVECs)中含有3(NLRP3)炎性体的pyrin结构域的激活,并且通过抑制AP-1活性来抑制这种作用,并且可以通过抑制这种作用来消除这种作用。过表达c-Jun。原花青素B2(2μM,12小时)也可降低HUVEC中的ROS [2]。 |
In Vivo | 原花青素B2(40,20和10mg / kg,口服)保护免受脑缺血诱导的大鼠梗塞体积和脑水肿。原花青素B2(40mg / kg,口服)也改善功能结果,调节脑缺血后的血脑屏障(BBB)通透性。此外,原花青素B2减轻脑缺血诱导的紧密连接降解,线粒体去极化和细胞内氧化应激。原花青素B2(40 mg / kg,po)可增加体内正常大脑中Nrf2的活化和HO-1,GSTα和NQO1蛋白的表达[3]。 |
Cell Experiment | 使MCF-7细胞在5mL补充有20%胎牛血清,青霉素(100U / mL)和链霉素(100μg/ mL)的RPMI 1640培养基中生长。将细胞保持在37℃,5%CO 2的空气湿润气氛中,每3天传代培养。将指数生长的细胞以2×10 4个细胞/ mL的接种密度接种在96孔板或培养皿中。在孵育过夜以允许附着后,将细胞暴露24或48小时至在蒸馏水中稀释的各种浓度的原花青素B2(0.5; 1.0; 5.0; 10.0; 25.0和50.0μM)。使用2毫摩尔环磷酰胺(CP)作为阳性对照,并通过过滤对溶液进行灭菌[1]。 |
Animal Experiment | 为了观察原花青素B2对梗死面积或脑水肿的影响,将40只大鼠随机分成5组,每组给予载体(通过管饲法施用相当剂量的0.9%盐水)或40,20或10mg /分别为kg的原花青素B2。为了阐明原花青素B2对血脑屏障(BBB)通透性的影响,大鼠(伊文思蓝外渗每组n = 6,IgG组泄漏每组n = 4)随机分为两组:载体和原花青素B2(40毫克/千克)。从大脑中动脉闭塞(MCAO)后3小时开始,每天一次胃内施用原花青素B2(40mg / kg)。对于其他观察,包括免疫组织学染色和蛋白质印迹分析,将大鼠随机分成三组:假手术,载体和原花青素B2(每组n = 4)。从MCAO后3小时开始,每天一次胃内施用原花青素B2(40mg / kg)。为了阐明大鼠缺血性中风后神经功能的改善,大鼠(每组n = 8)进行神经行为测定以评估在MCAO后24小时开始每天一次施用原花青素B2(40mg / kg)后的功能结果。 。在MCAO后1,3,7,11和14天评估神经功能缺损[3]。 |
