Biological Activity

Targets γ-secretase          
IC50 5 nM          

Protocol

Cell experiment: [1]

Cell lines

SH-SY5Y cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reacting condition

IC50: 5 nM.

Applications

As a moderately potent γ-secretase inhibitor, MK-0752 inhibited the production of Aβ40 in a dose-dependent manner with an IC50 of 5 nM in human SH-SY5Y cells.

Animal experiment : [1]

Animal models

Male CMP rhesus monkeys

Dosage form

Oral administration, 60 mg/kg and 240mg/kg

Application

Oral administration of MK-0752 demonstrated a dose-related reduction of Aβ levels. After 48 h, the Aβ levels with 240mg/kg treatment only recovered to 50%of baseline, while the 60mg/kg treatment group reached baseline at 30 h without overshoot. Plasma Aβ levels rebounded above baseline after MK-0752 inhibition (60 mg/kg, h 33–48).

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

MK-0752 is a potent gamma secretase inhibitor in clinical development (IC50 ~50 nM). Gamma secretase is an important component in the NOTCH cleavage machinery that catalyzes the cleavage of receptor protein substrates within their transmembrane domain. Inhibition of Notch inhibits BC cell proliferation in vitro. Notch signaling requires gamma secretase, which cleaves Notch, releasing the Notch intracellular domain (NICD) to activate transcription of target genes. NOTCH signaling plays an important role in normal tissue development, cell fate determination, proliferation, and survival. NOTCH signaling is activated following the binding of cognate ligands that include Delta1, Delta2, and Delta3 and Jagged1 and Jagged2.
