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. 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. L-685,458 also inhibit the Notch signaling, then affects embryonic development in zebrafish embryos.
