生物活性：
Semagacestat is a γ-secretase inhibitor, inhibits β-amyloid (Aβ42), Aβ38 and Aβ40 with IC50s of 10.9, 12 and 12.1 nM, respectively; also inhibits Notch signaling with IC50 of 14.1 nM. Semagacestat can be used for the research of alzheimer's?disease.
体内研究：
Semagacestat (LY450139) is found to decrease both Aβ42 and Aβ40 at 10 mg/kg (22-23% reduction;p<0.01) and increase β-CTF at 0.3-10 mg/kg in a dose-dependent manner (15-162% elevation; p<0.01 at 1-10 mg/kg). The γ-secretase inhibitor, Semagacestat (LY450139), a highly potent low molecular weight compound, significantly reduces β-amyloid (Aβ) levels in cell cultures permanently over-expressing APP and in both wildtype and transgenic APP-expressing mice. Three hours following p.o. dosing of 30 mg/kg Semagacestat levels of Aβ40 are reduced by 43% (unpaired t-test, p=0.002) in the brains of wildtype C57BL/6 mice compare with vehicle treated controls. Subcutaneous administration of Semagacestat (30 mg/kg) transiently decreases the amounts of Aβ40 in the dialysate with a maximum reduction in Aβ40 levels of 80% at 3 h post-dosing (p<0.001).
体外研究：
Semagacestat (LY450139) reduces the secretion of Aβ42, Aβ40, and Aβ38 in 96-well-cultured media and increases β-CTF in cell lysates as expected, although this increase is unexpectedly attenuated at high concentrations. In cortical neurons (CTX), Semagacestat (LY450139) causes a concentration-dependent decrease in Aβ40 secreted into the medium with IC50 value 111 nM for Semagacestat. Semagacestat causes a concentration-dependent decrease in Aβ40 and Aβ42 secreted into the medium with an IC50 value of 126 and 130 nM, respectively. Semagacestat (3 Μm; for 4 days) exhibits no significant cell toxicity in Huh7 cells.
