MRK-560
Based on 4 publication(s) in Google Scholar
MRK-560, a chemical probe, is an orally active, brain barrier-penetrated γ-Secretase inhibitor, reducing Aβ peptide in rat brain and cerebrospinal fluid. MRK-560 decreases mutant NOTCH1 processing by selectively inhibiting PSEN1. MRK-560 can be used in studies of Alzheimer's disease and T-cell acute lymphoblastic leukaemia (T-ALL).

Result:Reduced NICD1 generation in cells and resulted in a dose-dependent decrease of proliferation in HPB-ALL and DND-41, which depend on NOTCH signaling for their survival.
MRK-560 (1, 3, 10, 30, 100 mg/kg; p.o.; single) shows good blood-brain barrier permeability in a dose-dependent manner in rats[2].
MRK-560 (1, 3, 10, 30, 100 mg/kg; p.o.; single) inhibits the production of Aβ levels in brain and cerebrospinal fluid[2].
MRK-560 (1 mg/kg; p.o.; single) shows a good bioavailability of 70 to 90%, and Tmax is 12 h[2].
MRK-560 (1 mg/kg; i.v.; single) is suitable for once-a-day dosing (with a low plasma clearance and a half-life of more than 15 h)[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
