Description

Verubecestat, also known as MK-8931 or SCH 900931, is a potent and selective beta-secretase inhibitor, and BACE1 protein inhibitor or Beta-site APP-cleaving enzyme 1 inhibitor. Verubecestat is a promising novel therapeutic drug candidate in Alzheimer's disease. Verubecestat reduced Aβ cerebral spinal fluids (CSF) levels up to 92% and was well tolerated by patients.

How to use

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. Verubecestat has IC50s of 2.1 nM, 0.7 nM, 4.4 nM for Aβ1-40, Aβ1-42, sAPPβ in HEK293 APPSwe/Lon cells.

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. 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. 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. 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. 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. 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.
