一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
L-Alpha glycerylphosphorylcholine (alpha-GPC, choline alfoscerate) 是一种在大脑和牛奶中发现的天然胆碱化合物。它也是一种拟副交感神经乙酰胆碱前体[1],可能有治疗阿尔茨海默病[2]和痴呆症的潜力[3]。Alpha- gpc通过血脑屏障迅速向大脑传递胆碱,是乙酰胆碱神经递质的生物合成前体[2]。
功效:
研究已经调查了它对包括中风和阿尔茨海默氏症在内的认知障碍的疗效。一项意大利多中心临床试验对2044名近期中风患者进行了研究,在接下来的5个月里,每天提供alpha-GPC 1000mg剂量,连续28天,每天3次,每次400mg。本试验通过四种测量量表验证了alpha-GPC对患者认知恢复的治疗作用,其中三种测量量表具有统计学意义[4]。
