Based on 6 publication(s) in Google Scholar
L-685458 is a potent transition state analog (TSA) γ-secretase inhibitor (GSI). L-685458 inhibits amyloid β-protein precursor γ-secretase activity with IC50 of 17 nM, shows greater than 50-100-fold selectivity over other aspartyl proteases tested. L685458 inhibits γ-secretase-mediated cleavage of APP-C99 and Notch-100 with IC50s of 301.3 nM and 351.3 nM, respectively. L-685458 can be used for the research of alzheimer’s disease (AD) and cancers.
