γ secretase(aβ40)

Avagacestat (BMS-708163) (BMS-708163) is a potent, selective, orally bioavailable γ-secretase inhibitor of Aβ40 and Aβ42 with IC50 of 0.3 nM and 0.27 nM, demonstrating a 193-fold selectivity against Notch. Phase 2.

LY-411575, a potent γ-secretase inhibitor, is with IC50 of 0.078 nM in the membrane and 0.082 nM in cell-based. It also suppresses Notch clevage with IC50 of 0.39 nM.

Itanapraced (CHF5074), a γ-secretase modulator, reduces Aβ42 40 secretion (IC50: 3.6 18.4 μM).

MK-0752, a γ-secretase inhibitor, reduces Aβ40 production(IC50=5 nM).

BPN-15606, an orally active γ-secretase modulator (GSM), significantly reduces Aβ42 and Aβ40 production in SHSY5Y neuroblastoma cells, demonstrating IC50 values of 7 nM and 17 nM, respectively. This compound exhibits favorable pharmacokinetic pharmacodynamic (PK PD) properties, such as bioavailability, half-life, and clearance. Importantly, BPN-15606 markedly decreases Aβ42 and Aβ40 levels in the central nervous system of both rats and mice[1].

BPN-15606 besylate is a potent, orally active γ-secretase regulator (GSM) that reduces the production of Aβ42 (IC50: 7 nM) and Aβ40 (IC50: 17 nM) by SHSY5Y neuroblastoma cells. BPN-15606 besylate exhibited good PK PD properties (including bioavailability, half-life and clearance).

GSK-B, a potent γ-secretase modulator, decreases Aβ42, increases Aβ38 with no effect on Aβ40 levels.

BPN-15606 besylate is a highly potent, orally active γ-secretase modulator, attenuates the production of Aβ40 and Aβ42 by SHSY5Y neuroblastoma cells (IC50s: 7 nM and 17nM).

RO4929097 (RG-4733), a γ secretase inhibitor (IC50: 4 nM), inhibits cellular processing of Aβ40 and Notch (EC50: 14 5 nM).

Semagacestat (LY450139) (LY450139) is a γ-secretase blocker for Aβ42 Aβ40 Aβ38 (IC50: 10.9 12.1 12.0 nM) and also inhibits Notch signaling (IC50: 14.1 nM).
