產品描述：
LY-411575 is a potent inhibitor of γ-secretase with IC50 value of 0.078 nM in membrane assay.[1]
γ-Secertase 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 precursor protein.γ-Secertase 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.[2]
LY-411,575 significantly inhibits theγ-secretase activity in vitro. LY-411,575 inhibits the production of Aβproduction with IC50 value of 0.078 nM in membrane-assay and 0.082 nM in cell-basedγ-secretase assays, respectively. LY-411,575 also affects the Notch pathway by inhibiting Notch S3 cleavage with IC50 value of 0.39 nM.[1] LY-411,575 treatment also significantly inhibited the Notch pathway by inhibiting the γ-secretase activity luciferase activity in primary KS cells. LY-411,575 also induced the apoptosis though Notch pathway inhibition in primary and immortalized Kaposi's sarcoma (KS) tumor cells.[2]
LY-411,575 decreases the levels of brain and plasma Aβ40 and -42 at 10 mg/kg oral doses.[1] LY-411,575 also decreases cortical Aβ40 levels in transgenic CRND8 mice with ED50 ≈ 0.6 mg/kg. LY-411,575 also induced significantly intestinal goblet cell hyperplasia and thymus atrophy by inhibiting Notch signaling pathway at higher doses in vivo.[3]
