OX-201
OX-201 is an orally active, blood-brain barrier-permeable OX2R agonist with an EC50 of 8.0 nM. OX-201 activates OX2R to induce wakefulness and neuronal activation. OX-201 promotes the release of neuron activity-dependent tau protein from neurons into the interstitial fluid of hippocampal tissues. OX-201 is applicable to research related to Alzheimer's disease and tauopathies.

OX1 Receptor 8.1 μM (EC50) |
OX-201 (8.0 nM-10 μM) is a potent, highly selective OX2R agonist with minimal off-target activity in cell-based in vitro assays[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
OX-201 (3-30 mg/kg; p.o.; single administration or once daily for consecutive 2 months) enhances wakefulness during the active phase in male human P301S tau transgenic mice; at the dose of 30 mg/kg, it induces neuronal activation and increases interstitial fluid (ISF) tau levels in the hippocampus, while the regimen of 30 mg/kg once daily for consecutive 2 months does not exacerbate hippocampal tau aggregation[1].

-
Animal Model:C57BL/6J (male, 8-12 weeks old)[1]
-
Dosage:10 mg/kg; 30 mg/kg; 100 mg/kg
-
Administration:p.o.; single dose
-
Result:Significantly increased total wakefulness time over 6 hours post-administration during the sleep phase, with dose-dependent effects.
Showed a non-significant tendency to increase hippocampal ISF tau levels for 4.5 hours at 100 mg/kg.
Significantly increased hippocampal ISF lactate levels for 7.5 hours at 100 mg/kg.
Had no clear effect on hippocampal ISF glucose levels at 100 mg/kg.
-
Animal Model:human P301S tau transgenic (Tg) (male, 7-9 months old, tauopathy model)[1]
-
Dosage:3 mg/kg; 10 mg/kg; 30 mg/kg (single dose wakefulness/ISF studies); 30 mg/kg (chronic 2-month tau accumulation study)
-
Administration:p.o.; single dose; once daily for 2 months
-
Result:Significantly increased total wakefulness time during the 6-hour window post-administration (ZT13-18) during the active phase, with no residual effect on wakefulness during the subsequent sleep phase, at 3, 10, and 30 mg/kg.
Increased hippocampal ISF tau levels for > 16.5 hours at 30 mg/kg.
Increased ISF lactate levels for >6 hours at 30 mg/kg.
Increased ISF glucose levels at 30 mg/kg.
Did not alter total hippocampal tau levels after chronic once-daily administration of 30 mg/kg for 2 months.
