| 体外研究 |
DAPT功能性抑制γ-分泌酶而降低HEK 293细胞中全部Aβ产量，IC50为20 nM。DAPT作用于原代培养的人神经细胞，也抑制Aβ产量，作用于全部Aβ和Aβ42时, IC50分别为115 nM和200 nM，比作用于HEK 293细胞时低5-10倍。最新研究显示DAPT 抑制SK-MES-1 细胞增殖，这种作用存在浓度依赖性，IC50为11.265 μM。此外, DAPT作用于肺鳞状细胞癌细胞，通过抑制Notch受体信号通路，也诱导依赖型和非依赖型细胞凋亡。[1] |

| 体内研究 | DAPT按100mg/kg剂量处理PDAPP小鼠，产生强劲和持久的药效，1小时内脑中 DAPT水平超过100 ng/g ，且处理后，持续上升达18小时，3小时后的时候观察到最高水平为490 ng/g。在此期间, DAPT 按100 mg/kg剂量处理，也降低大脑皮层全部Aβ和Aβ42，这种作用存在剂量依赖性，降低50%。[1] DAPT按40 mg/kg剂量作用于大鼠大脑皮层, 抑制LPS诱导的γ分泌酶活性，且提高携带长期神经炎症的细胞凋亡。[3] |

体外Aβ减少检测实验 : 转染APP751(HEK 293)基因的人类胚胎肾细胞，用于常规 Aβ减少检测。细胞接种在96孔板上，在含10%热灭活胎牛血清的DMEM培养基上粘附过夜。 DAPT 在 DMSO中稀释，终浓度为0.1% DMSO。使用DAPT在37oC下预处理细胞2小时，吸除培养基，使用新鲜实验化合物溶液。再处理2小时后，抽除条件培养基，使用标准 ELISA(266-3D6)分析全部Aβ。根据使用 0.1% DMSO 处理的对照组细胞，测量Aβ产量的减少，表示为抑制百分数。实验至少按6种剂量重复进行，得到实验数据，然后使用XLfit软件拟合四参数方程，测定 药性。培养的人和PDAPP小鼠神经细胞在无血清培养基上生长，增强他们的神经元特性，其中有90%以上神经元在实验使用前成熟。通过在每孔中加入新鲜培养基，然后在没有DAPT存在时，在37oC下温育24小时，收集条件培养基中得到的基底Aβ值。使用含DAPT的新鲜培养基，按所需浓度范围在37oC下再处理培养细胞24小时，收集条件培养基。为了测量全部Aβ,使用与HE2K 293细胞实验 相同的ELISA(266-3D6) 分析样本。通过分开的ELISA(21F12-3D6)，使用特定Aβ42 C-端捕获抗体，进行Aβ42 产量分析。测定对全部Aβ和Aβ42产量的抑制情况。绘制与DAPT浓度相对的抑制百分数,使用 XLfit 软件分析数据，测定药性。 |

常见问题及建议解决方法
-
问题 1：
Could you please help test the formulation of S2215 for in vivo studies?
-
回答：
S2215 DAPT in 30% PEG400+0.5% Tween80+5% Propylene glycol at 10 mg/ml is a suspension. We tried to add some EtOH, and it dissolved clearly in organice solvents, but when water added, the precipitation went out immediately. Then we tried other vehicles, and found S2215 can be dissolved in 4% DMSO+corn oil at 10 mg/ml clearly.
-
问题 2：
I would like to ask if you would recommend this product used in endothelial cells (e.g. both murine and human endothelial cells).
-
回答：
I think DAPT can be used in endothelial cells from both human and mouse, please see the following reference: http://www.ncbi.nlm.nih.gov/pubmed/19481797; http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2615564/
