體外研究: |
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. 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 BMS-790052 (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. LY411575 significantly attenuates EMT by inhibiting the Notch signaling activation in vitro. |
體內研究: |
LY-411,575 (10 mg/kg) decreases brain and plasma Aβ40 and -42 robustly when chronically administered to TgCRND8 mice. 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. LY411575 inhibits mouse proliferative vitreoretinopathy (PVR) formation in vivo. |
