產品描述：
L-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 Aβ?by 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].
