General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.Reacting condition48 hoursApplicationsIn HeLa and SiHa cells, L-685,458 (8 μM) blocked Notch activation. In L-685,458-treated cells, Hes1 nuclear translocation was largely blocked and about 6.63% of HeLa and 9.03% of SiHa cells were subjected to apoptosis. L-685,458 (10 μM, 3 days) inhibited Notch pathways and caused accumulation of oocytes at the pachytene stages and decreased the number of oocytes that are able to reach diplotene. In SGHPL-5 cells, L-685,458 suppressed canonical notch activity. L-685,458 significantly increased the amount of BrdU-labeled primary CTB cells. L-685,458 increased migration of SGHPL-5 cells. L-685,458 (10 μM, 48 hours) strongly increased motility of the nonproliferating EVTs. L-685,458 (0.5 μM) attenuated the isoflurane-induced increase in Tau-PS262 levels in WT mice and AD Tg mice primary neurons.Other notesPlease test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.References:[1]. Zhang P, Li H, Yang B, et al.

BackgroundL-685,458 is a selective and Potent inhibitor of γ-secretase with IC50 value of 17 nM[1]. γ-Secretase is one of intramenbrane-cleaving aspartyl protease which cleaves many type-I membrane proteins and many of them have important biological functions. γ-Secretase is a multi-subunit protease and it contains presenilin, nicastrin, APH-1(Anterior Pharynx- defective 1) and PEN-2. Presenilin contains Asp258 and Asp385 embedded in the sixth and seventh transmembrane domain and forms the active site. The feature of being a membrane integrated protease complex makes it difficult to be purified as well as studying its mechanism. γ-secretase is responsible for the generation Aβfrom the amyloid precusor protein. γ-Secretase has been considered as an important drug target for Alzheimer"s disease. γ-Secertase also is responsible for Notch processing which is related to cancer such as leukemia.L-685,458 is a transition state analogue inhibitor.It is a pan-inhibitor of γ-secretase which decrease the products of Aβ(42) and Aβ(40) peptides. It displays a selectivity of 50-fold or greater inhibition than a range of aspartyl, serine, and cysteine protease in vitro membrane assay. L-685,458 reduced the product both total Aβand Aβ42 in human primary neuronal cells with IC50 value of 115 nM for Aβand Aβ42 for 200 nM[2]. L-685,458 also inhibitedγ-secretase activity by characterizing the production of total secreted Aβby ELISA with IC50 value of about 5 nM in HEK 293 cells overexpressing human APP751.L-685,458 reduced the cortical total Aβwith a 50% reduction occurring at 100 mg/kg in a dose-dependent manner in PDAPP, and similar reductions in cortical Aβ42 were observed. L-685,458 decreased brain levels of Aβwhen given orally to Tg2576 mice that are transgenic for human APPV717F mutation. [3] L-685,458 also inhibit the Notch signaling, then affects embryonic development in zebrafish embryos[4].References: 1.Shearman MS, Beher D, Clarke EE, Lewis HD, Harrison T, Hunt P, Nadin A, Smith AL, Stevenson G, Castro JL: L-685,458, an aspartyl protease transition state mimic, is a potent inhibitor of amyloid beta-protein precursor gamma-secretase activity.
