BMS-708163 (Avagacestat), γ-Secretase Inhibitor

BMS-708163 (Avagacestat) is a potent, selective and orally bioavailable γ-secretase inhibitor with an IC50 of 0.3 nM for APP cleavage. It is 190-fold more selective for APP than Notch, having an IC50 of 58 nM for Notch. Phase I clinical trial studies showed that in humans, BMS-708163 decreased CSF Aβ40 and Aβ42 approximately 30% following daily dose of 100 mg after 28 days and by 60% at daily dose of 150 mg.

How to use

In Vitro:

BMS-708163 was used at 1-10 µM in vitro.

In Vivo:

BMS-708163 was dosed orally in female rats at 10 and 100 mg/kg once per day, and could significantly reduced both plasma and brain Aβ40 levels relative to control for the entire dosing interval.
