Mechanism of Action

Features	Appears to be more “notch sparing” than semagacestat (LY450139).
Targets/IC₅₀/Ki	Aβ42 ^[1] (in H4-8Sw cells) 0.27 nM Aβ40 ^[1] (in H4-8Sw cells) 0.3 nM
In vitro	Avagacestat (BMS-708163) exhibits weaker selectivity for inhibition of Notch processing with 193-fold IC50 value. ^[1]
In vivo	Avagacestat (BMS-708163) significantly reduces Aβ40 levels for sustained periods in brain, plasma, and cerebrospinal fluid in rats and dogs following oral administration. It has no dose-limiting effects in dogs (3 mg/kg during 6 months), with a high brain to plasma ratio (2.4). ^[1]
