DAPT (GSI-IX)DAPT (GSI-IX)是一种新型γ-secretase抑制剂，抑制 Aβ产生，在HEK 293细胞中IC50为20 nM。DAPT可促进人类舌癌细胞的凋亡并调节自噬。 |

RO4929097RO4929097是一种γ secretase抑制剂，无细胞试验中IC50为4 nM，抑制Aβ40和Notch的细胞加工，EC50分别为14 nM和5 nM。Phase 2。 |

Semagacestat (LY450139)Semagacestat (LY450139)是一种γ-分泌酶抑制剂，作用于Aβ42，Aβ40和Aβ38，IC50分别为10.9 nM，12.1 nM和12.0 nM，也抑制Notch信号通路，人神经胶质瘤细胞中IC50为14.1 nM。Phase 3。 |
HEK/APPswe cells were either left non-treated (-) or exposed to the γ-secretase inhibitor (GSI) semagacestat (+) for 19 h prior to cell harvesting and membrane preparation (Substrate accumulation). Exposure of cells with GSI prior to membrane preparation results in higher Aβ1-42 and Aβx-42 signals as compared to membranes derived from non-GSI treated cells. Direct addition of semagacestat to the membranes in the novo Aβ production assay inhibited Aβ production (Semagacestat (1 µM)). The amount of Aβx-42 is higher than Aβ1-42 suggesting that C83 is the major substrate for the Aβ42 signal detected. |

A panel of GICs lines was treated with various concentrations of γ secretase inhibitors BMS-708163. Cells were treated with increasing concentrations of γ secretase inhibitors in triplicate wells for 72 hours, and cell viability was assessed by CellTiter-Blue assay as described in Materials and Methods. The results shown are of a single experiment with three independent replicates cell viability was measured by CellTiter-Blue assay. The graph depicts cell viability at 72 hours. Cell viability in the vehicle control was considered as to be 100%. |
