Bioactivity | ELN318463 is an amyloid precursor protein (APP) selective γ-secretase inhibitor. ELN318463 shows differential inhibition of presenilin (PS1)- and PS2-comprised γ-secretase with EC50s of 12 nM and 656 nM for PS1 and PS2, respectively. ELN318463 is 51-fold more selective for PS1[1][2]. | ||||||||||||
Target | EC50: 12 nM (PS1 γ-secretase), 656 nM (PS2 γ-secretase) | ||||||||||||
Invitro | ELN318463 behaves as a classic γ-secretase inhibitor, demonstrates 75- to 120-fold selectivity for inhibiting Aβ production compared with Notch signaling in cells, and displaces an active site directed inhibitor at very high concentrations only in the presence of substrate[2]. | ||||||||||||
In Vivo | ELN318463 (30 mg/kg or 100 mg/kg; orally) leads acute reduction of brain Aβ in in the PDAPP transgene model of Alzheimer's disease (AD) as well as in wild-type FVB strain mice[2]. Animal Model: | ||||||||||||
