Application

MK-8719 may be used in enzyme and cell-based assays to analyze its inhibitory effects on O-GlcNAcase activity and to assess its binding kinetics via surface plasmon resonance.

Biochem/physiol Actions

MK-8719 is an orally available, brain-penetrant, potent and selective O-GlcNAcase (OGA) inhibitor (Ki in nM = 7.9/human, 9.7/rat, 12.1/dog, 9.7/mouse) that upregulates O-linked N-acetylglucosamine (O-GlcNAc) levels both in cultures (EC50 = 52.7 nM in rat PC-12 cells) and in vivo (fold increase = 3.2 in brain and 2.2 in PBMC 8h post 10 mg/kg p.o. in rats). Chronic MK-8719 treatment ameliorates brain atrophy in human mutant tau (P301L) expressing rTg4510 mice (100 mg/kg b.i.d. p.o. from 8 to 32 weeks of age).
