Notes: γ-Secretase is a protease complex that cleaves single-pass transmembrane proteins, such as Notch receptors and β-amyloid precursor protein (APP), within the transmembrane domain.{27051,25415} Avagacestat is a potent, orally bioavailable inhibitor of γ-secretase that more potently inhibits the cleavage of APP to Aβ40 than signaling through Notch (IC50s = 0.30 and 58 nM, respectively).{27425} It shows good pharmacokinetics in rats, dogs, and humans and passes the blood-brain barrier, reducing plasma, brain, and cerebrospinal fluid Aβ40 levels.{27425,27428} While suppressing the production of Aβ38, Aβ40, and Aβ42, γ-secretase inhibitors, including avagacestat, increase the level of APP β-C-terminal fragment, both in vitro and in vivo, altering cell function.{27426} Avagacestat may impact Notch signaling in vivo, although it is generally considered a “Notch-sparing” γ-secretase inhibitor.{27427}
