产品介绍

L-685458 是一种有效的过渡状态模拟(TSA) γ-分泌酶 (γ-secretase) 抑制剂 (GSI)。L-685458 抑制淀粉样 β-蛋白前体 γ-分泌酶活性，IC₅₀ 为 17 nM，选择性高于其他检测的天冬氨酸蛋白酶 50-100 倍。L-685458 抑制 γ-分泌酶介导的 APP-C99 和 Notch-100 的裂解，IC₅₀ 分别为 301.3 nM 和 351.3 nM。L-685458 可用于阿尔茨海默病 (AD) 和癌症的研究。

生物活性

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.

体外研究

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^[4].
