Description: LY900009 is a small molecule inhibitor of Notch signalling via selective inhibition of the γ-secretase protein. LY900009 inhibited plasma levels of amyloid-β peptide in a dose-dependent manner with 80-90% inhibition observed in the 30- to 60-mg cohorts. LY900009 is an orally available GSI (Aβ: IC50= 10.9−12.1 nM; Notch: IC50 = 14.1 nM) that was developed as a candidate therapeutic drug against AD (IDENTITY trial), which failed in phase III trials.
