Description |
MK-0752 is a moderately potent γ-secretase inhibitor, which reduces Aβ40 production with IC50 of 5 nM.IC50 value: 5 nM (reduces Aβ40 production) [1]Target: γ-secretasein vitro: MK-0752 is identified as a moderately potent γ-secretase inhibitor, which reduces Aβ40 in a dose-dependent manner with an IC50 of 5 nM in human SH-SY5Y cells [1]. In vitro, MK-0752 blocks Notch-intracellular domain (ICD) cleavage and its subsequent nuclear translocation [2]. in vivo: MK-0752 (240 mg/kg) reduces the generation of newly produced Aβ with 90% decrease of AUV in the brain of rhesus monkeys. In addition, MK-0752 treatment increases levels of Aβ 1-14, Aβ 1-15, and Aβ 1-16 , while decreases levels of Aβ 1-17 [1]. In guinea-pigs, oral administration of MK-0752 (10 mg/kg -30 mg/kg) results in the dose-dependent reduction of Aβ40 in plasma, brain and cerebrospinal fluid (CSF) with IC50 of 440 nM in brain [2].
