将细胞以每孔2.5×103铺板于96孔组织培养板上并孵育一个细胞倍增(18-24小时)。吉西他滨稀释液通过半对数步骤设定,最终浓度范围为1-1000nM。通过在DMSO中稀释至5000×终浓度制备LY2603618,然后将1000倍稀释到培养基中以产生5x原液以添加到孔中。加入吉西他滨后约24小时,加入LY2603618。每种组合一式三份进行。在添加LY2603618后两次细胞倍增一段时间后,根据制造商的说明将MTS/PMS试剂加入每个孔中。在Spectra Max 250分光光度计上在490nm处读取吸光度,并用GraphPad Prism 4.0分析数据。剂量 – 反应曲线通过非线性回归拟合,底部拟合约束为0%抑制[1]。

来自老年人群(16-26个月大)的小鼠是退休的育种者或实验性幼稚小鼠。在开始给药之前和研究期间,将小鼠单独用塑料冰屋和筑巢材料饲养。在最后给药后2至4小时处死小鼠。对于口服给药,将LY411,575和LY-D配制成10mg / mL溶液,并用0.4%甲基纤维素1:10稀释。在皮下给药的情况下,将10mg / mL储备溶液用20%羟基 – 丙基-β-环糊精1:10稀释。如有必要,使用适当的1:10载体从1 mg / mL溶液中进行连续稀释。剂量体积为10 mL / kg。口服10mg / kg LY411,575后,给药后血浆Aβ的抑制仍然显著24,但不是48小时,因此为了维持连续的γ-分泌酶抑制,LY411,575和LY-D给药所有研究中每天一次。
