Use | LY-411575 |
In vitro study | LY-411575 inhibits gamma-secretion, which can be assessed by substrate amyloid precursor protein (APP) and Notch S3 cleavage. In primary and immortalized KS cells, LY-411575 blocked Notch activation, leading to apoptosis. |
In vivo study | A LY-411575 dose-dependent reduction in brain and plasma Aβ40 and Aβ42 was achieved at an oral dose of 10 mg/kg. In young transgenic CRND8 mice, LY-411575 reduced cortical Aβ40(ED50 ≈ 0.6 mg/kg), and at higher doses (>3 mg/kg), significant thymic atrophy and intestinal goblet cell hyperplasia. The therapeutic window was similar for both oral and subcutaneous administration in young and old CRND8 mice. Thymic and intestinal side effects are reversible after a 2-week washout period. Treatment with 1 mg/kg LY411575 for 3 weeks reduced cortical Aβ40 by 69% without inducing an intestinal effect, although a previously unreported change in coat color would be observed. |

biological activity | LY411575 is an effective γ-secretase inhibitor. IC50 is 0.078 nM/0.082 nM (based on membrane/cell) in HEK293 cells expressing APP or NΔE, which also inhibits Notch division and IC50 is 0.39 nM. LY411575 can induce apoptosis. |

in vivo study | 10 mg/kg oral dose LY-411575 dose-dependent reduction of brain and plasma Aβ40 and Aβ42. In young (preplaque) transgenic CRND8 mice, the cortical layer Aβ40(ED50 ≈ 0.6 mg/kg) was LY-411575 reduced, and at higher doses (>3 mg/kg), significant thymus atrophy and intestinal goblet cell proliferation were produced. In young and old CRND8 mice, oral and subcutaneous administration, the therapeutic window is similar. Thymus and intestinal side effects are reversible after a 2-week clearance period. Treatment with 1 mg/kg LY411575 for 3 weeks reduced 69% cortical Aβ40 without inducing intestinal effects, although previously unreported changes in coat color would be observed. |
