Isoform Comparison

Biological Activity

Description
L-685458 serves as a potent γ-secretase inhibitor (GSI), classified as a transition state analog (TSA), and effectively inhibits amyloid β-protein precursor γ-secretase activity with an IC50 of 17 nM, displaying more than 50-100-fold selectivity against other tested aspartyl proteases. This compound impedes γ-secretase-mediated cleavage of APP-C99 and Notch-100 with IC50 values of 301.3 nM and 351.3 nM, respectively, and is investigated for its potential in Alzheimer’s disease (AD) and cancer research[1].[2].

Hippocampal neurons 1 µM 24 h Inhibited γ-secretase activity, increased mEPSC frequency and amplitude PMC3169340
SKOV3 cells 0.5 and 2 μM To investigate the inhibitory effect of L-685458 on γ-secretase activity, results showed that L-685458 significantly blocked the production of p80Her2. PMC7734010
Primary neurons of AppSwe mice 1 µM 12 h To investigate if NHE6 inhibition or knockdown alters BACE1 activity, results showed that NHE6 inhibition or knockdown did not alter BACE1 activity, and the amount of β-CTF remained unchanged. PMC8547963
Inner ear stem cells 1 μg/ml 5 days Inhibition of γ-secretase increased the differentiation of inner ear stem cells into hair cells, as evidenced by increased immunostaining for myosin VIIa and Math1. PMC3136123
