Description

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.

How to use

In Vitro:

L-685458 reduces both Aβ(40) and Aβ(42) peptide formation in 3 different cells. It against Neuro2A h AβPP695, CHO h AβPP695, and SHSY5 spβA4CTF reduction of Aβ(40) with IC50 values of 402 nM, 113 nM and 48 nM, respectively. And the IC50 values are 775 nM, 248 nM, 67 nM, respectively. L-685458 (5-40 μM; 24 hours) leads to a dramatic downregulation of Hes-1 in 786-O cells. L-685458 has inhibitory effects in hepatoma cell lines, it against Huh7, HepG2, HLE and SKHep1 cells with IC50 of 12.91 μM, 12.69 μM, 21.76 μM and 12.18 μM, respectively.

In Vivo:

L-685458 (percutaneous administration; 5 mg/kg; 2 weeks) has antitumor effects in mouse hepatoma models. L-685458 inhibits EpCAM production except in necrotic areas. And HES1 staining is also diminished in the nucleus.
