MW073
MW073 is a highly selective and orally active 5-HT2BR antagonist (IC50 =70 nM). MW073 exerts its effects by concentration-dependently inhibiting receptor activity and β-arrestin-1 recruitment. MW073 ameliorates synaptic plasticity and behavioral deficits, including aggression, in Alzheimer’s disease (AD) mouse models. MW073 can be used for Alzheimer’s disease (AD) research[1][2].

Biological Activity
|
5-HT2B Receptor 70 nM (IC50) |
MW073 (0.1-10 μM) demonstrates that its biochemical mechanism of action for both h5-HT2BR (Kd = 86 nM, EC50Gprotein = 1.1 μM, EC50β-Arrestin1 = 2.4 μM) and m5-HT2BR (Kd = 125 nM, EC50Gprotein = 6.7 μM, EC50β-Arrestin1 = 0.6 μM) is the dose-dependent inhibition of both serotonin-induced activation/β-arrestin-1 recruitment and basal constitutive activity in transfected HEK293A cells, suggesting inverse agonism[1].
MW073 exhibits only 5-HT2BR antagonist activity when subjected to large-scale cellular screening of 165 diverse G Protein-Coupled Receptors (GPCRs) for agonist and antagonist activity using a panel of stably transfected CHO cell lines[1].
MW073 exhibits no activity against kinases, key enzymes, or transporters, and its lack of CYP450 substrate status predicts low drug-interaction potential[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
MW073 (0-5 mg/kg, p.o., q.d. for 30-45 days starting at the age of day 60-70) dose-dependently prevents and ameliorates memory deficits in APP/PS1 mice[1].
MW073 (5 mg/kg, p.o., q.d. for ~150-250 days) restores synaptic and memory function in hTau/Mapt-KO mice, proving effective in both preventive and therapeutic intervention paradigms during chronic treatment[1].
MW073 (5 mg/kg, i.p., q.d. for 3 weeks) reduces aggressive behavior without inducing sedation or hypoactivity in Tg2576 mice[2].
