Biological Activity for MRK 560

MRK 560 is a γ-secretase inhibitor, which selectively inhibits proteolytic cleavage of amyloid precursor protein (APP) over the Notch pathway. MRK 560 reduces levels of Aβ in vitro (inhibits Aβ40 and Aβ42 in SH-SY5Y neuroblastoma cells with an IC₅₀ of 0.65 nM) and attenuates plaque deposition. This compound is orally bioavailable.
