one of dimeric derivatives of ferulic acid. Intragastric pretreatment of mice with KMS4001 (30mg/kg/day) for 5 days significantly attenuated the Aß1-42 (i.c.v.)-induced memory impairment both in passive avoidance test and in Y-maze test. APP/PS1 mutant transgenic mice at KMS4001 doses of 3 and 30mg/kg/day via drinking water showed the significantly enhanced novel-object recognition memory at both 1.5
阿魏酸是具有有效的抗氧化剂和抗炎活性的化合物。我们以前曾报道过阿魏酸对两种阿尔茨海默氏病(AD)动物模型的保护作用:在小鼠和APP / PS1突变转基因小鼠中脑室内(icv)注射Aß1-42。在使用相同AD动物模型的这项研究中,我们检查了阿魏酸二聚体衍生物之一KMS4001的作用。在被动回避测试和Y迷宫测试中,用KMS4001(30mg / kg /天)对小鼠进行胃内预处理5天可显着减轻Aß1-42(icv)引起的记忆障碍。通过KMS4001剂量分别为3和30mg / kg / day的饮用水通过APP / PS1突变体转基因小鼠在开始KMS4001治疗后1.5和3个月都显示出显着增强的新对象识别记忆。用KMS4001以3和30mg / kg /天的剂量治疗APP / PS1突变转基因小鼠3个月,额叶皮层中Aβ1-40和Aβ1-42水平明显降低。KMS4001的Aβ剂量-反应关系降低,而新
