Description

Verubecestat (MK-8931) is an orally active, high-affinity BACE1 and BACE2 inhibitor with Ki values of 2.2 nM and 0.38 nM. Verubecestat effectively reduces Aβ40 and has the potential for Alzheimer's Disease[1][2].

In Vitro

Verubecestat (MK-8931) is a β-site amyloid precursor protein cleaving enzyme 1/2 (BACE1/2) inhibitor. Verubecestat does not significantly inhibit human CYP isoforms 1A2, 2C9, 2C19, 2D6, and 3A4 (all IC50>40 μM), indicating that the compound is unlikely to be a perpetrator of CYP-mediated drug-drug interactions[1].
Verubecestat has IC50s of 2.1 nM, 0.7 nM, 4.4 nM for Aβ1-40, Aβ1-42, sAPPβ in HEK293 APPSwe/Lon cells[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Verubecestat (MK-8931; 3 mg/kg; IV or oral) has a T1/2 of 1.9 hours, a CL of 46 mL/min/kg, a Vss of 5.4 L/kg, a C max of 0.27 μM and a AUC of 1.1 μM•h for Sprague-Dawley (SD) rats[1].
Verubecestat (1 mg/kg; IV) has a T1/2 of 4.9 hours, a CL of 21 mL/min/kg, a Vss of 7.5 L/kg for cynomolgus monkeys[1].
Verubecestat (1 mg/kg; IV) has a T1/2 of 9.7 hours, a CL of 4.3 mL/min/kg, a Vss of 2.7 L/kg for beagle dogs[1].
Verubecestat (30 mg/kg; orally; BID for 5 days) causes a modest (1.4-fold) induction of CYP 3A1 activity but does not significantly alter the expression of CYPs 1A1, 1A2, 2B, 3A2, or 4A in rats[1].
Verubecestat dose-dependently reduces CSF and cortex Aβ40 with ED50 values of 5 and 8 mg/kg, respectively, corresponding to unbound plasma EC50 values of 48 and 81 nM, respectively[1].
Verubecestat (3 and 10 mg/kg; orally) reduces profound, sustained of CSF Aβ40 levels and has peak effects on CSF Aβ lowering (72 and 81% reduction at 3 and 10 mg/kg, respectively) 12 h after dosing[1].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (6.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
