Mechanism of Action

Features	A moderately potent γ-secretase inhibitor.
Targets/IC₅₀/Ki	Aβ (in human SH-SY5Y cells) 5 nM
In 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. In vitro, this compound blocks Notch-intracellular domain (ICD) cleavage and its subsequent nuclear translocation.
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, this compound treatment increases levels of Aβ 1-14, Aβ 1-15, and Aβ 1-16 , while decreases levels of Aβ 1-17. In guinea-pigs, oral administration of this chemical (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.
