Biological Activity
LY-411575 is a potent γ-secretase inhibitor with IC50 of 0.078 nM/0.082 nM (membrane/cell-based), and also inhibits Notch S3 cleavage with IC50 of 0.39 nM.
In Vitro
LY-411,575 blocks Notch activation, and results in apoptosis in primary and immortalized KS cells. LY-411,575 (500 μM) induces G2/M growth arrest SLK cells[2]. LY411575 treatment significantly decreases the amounts of intracellular HCV RNA with IC50 of 0.56 ± 0.20 μM and extracellular HCV particles. LY411575 (0-40 nM) alone or in combination with daclatasvir (0-40 pM) decreases supernatant infectious titers in a dose-dependent manner, and is synergistic regarding production of infectious virus. LY411575 (10 µM) treatment impairs ROS production in HCVcc-infected cells[4]. LY411575 significantly attenuates EMT by inhibiting the Notch signaling activation in vitro[5].
In Vivo
LY-411,575 (10 mg/kg) decreases brain and plasma Aβ40 and -42 robustly when chronically administered to TgCRND8 mice[1]. LY411,575 reduces cortical Aβ40 in young transgenic CRND8 mice (ED50 appr 0.6 mg/kg) and produces significant thymus atrophy and intestinal goblet cell hyperplasia at higher doses (>3 mg/kg). The extent of intestinal goblet cell hyperplasia induced by LY411,575 (10 mg/kg) is similar in young and aged mice[3]. LY411575 inhibits mouse proliferative vitreoretinopathy (PVR) formation in vivo[5].
