O-GlcNAcase-IN-6 is an orally active, blood-brain barrier-permeable O-GlcNAcase (OGA) inhibitor with an IC50 of 5.4 nM. O-GlcNAcase-IN-6 inhibits OGA activity, thereby increasing the level of O-GlcNAc glycosylation in brain tissues. O-GlcNAcase-IN-6 can be used for the research of Alzheimer's disease.

Description

O-GlcNAcase-IN-6 is an orally active, blood-brain barrier-permeable O-GlcNAcase (OGA) inhibitor with an IC50 of 5.4 nM. O-GlcNAcase-IN-6 inhibits OGA activity, thereby increasing the level of O-GlcNAc glycosylation in brain tissues. O-GlcNAcase-IN-6 can be used for the research of Alzheimer's disease[1].

In Vitro

O-GlcNAcase-IN-6 (Compound 24) potently inhibits human OGA by directly binding to the active site of the enzyme, with an IC50 value of 5.4 nM[1].
O-GlcNAcase-IN-6 inhibits OGA activity in HEK293 cells with an IC50 of 26 nM[1].
O-GlcNAcase-IN-6 exhibits low in vitro MDR1-MDCK permeability of 0.7 × 10-6 cm/s, a high P-glycoprotein (PgP) efflux ratio (> 28), a free plasma protein binding rate of 0.61, and a free brain tissue binding rate of 0.24[1].

In Vivo

O-GlcNAcase-IN-6 (Compound 24) (100 mg/kg; p.o.; single dose) induces a transient, significant elevation of brain O-GlcNAcylation levels in male CD1 mice, confirming in vivo OGA target engagement[1].

Animal Model: CD1 mice (male)[1]
Dosage: 100 mg/kg
Administration: p.o.; single dose
Result: Induced a transient elevation of brain O-GlcNAcylation levels, peaking at 8 hours post-administration.
Reached a peak increase similar to the 3-3.5-fold increase observed with the reference compound Thiamet-G (500 mg/kg).
Showed measurable brain exposure, with an AUC(brain)/AUC(plasma) ratio of 0.16 and an unbound brain-to-plasma partition coefficient (Kp,uu) of 0.07.

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.
