Biological Activity

Description Verubecestat (MK-8931) is a potent and selective beta-secretase (also known as Beta-site APP-cleaving enzyme 1) inhibitor.
BACE2 [1]
(Cell-free assay)
BACE1 [1]
(Cell-free assay)
0.37 nM(Ki) 1.75 nM(Ki)
In vitro

Verubecestat(MK-8931) effectively reduces Aβ40 in cells with a Ki of 7.8 nM and an IC50 of 13 nM[2].

In vivo Verubecestat(MK-8931) dramatically lowers CSF and cortex Aβ40 in both rats and cynomolgus monkeys following a single oral dose. Due to the 20 h half-life of MK-8931 it is ideal for once-a-day dosing[2].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
