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.

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[1][2].
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[1].L-685458 (5-40 μM; 24 hours) leads to a dramatic downregulation of Hes-1 in 786-O cells[3].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[4].

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
