DAPT (GSI-IX)DAPT (GSI-IX) is a novel γ-secretase inhibitor, which inhibits Aβ production with IC50 of 20 nM in HEK 293 cells. DAPT enhances the apoptosis of human tongue carcinoma cells and regulates autophagy. |
Western blotting showing increased unconjugated SUMO1 levels in Notch1 ΔE cells treated with 10 uM DAPT for 3 days. Tubulin was used as a loading control.

RO4929097RO4929097 is a γ secretase inhibitor with IC50 of 4 nM in a cell-free assay, inhibiting cellular processing of Aβ40 and Notch with EC50 of 14 nM and 5 nM, respectively. Phase 2. |

Semagacestat (LY450139)Semagacestat (LY450139) is a γ-secretase blocker for Aβ42, Aβ40 and Aβ38 with IC50 of 10.9 nM, 12.1 nM and 12.0 nM, also inhibits Notch signaling with IC50 of 14.1 nM in H4 human glioma cell. 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. |
