Biochem/physiol Actions

Primary TargetNurr1/NR4A2

Cell permeable: yes

General description

A cell-permeable, isoxazolopyridinone compound that acts as a potent activator of Nurr1/NR4A2-dependent transcription activity in reporter assays using Nurr1-expressing murine midbrain dopaminergic neuronal cell line MN9D (EC₅₀ = 3.9 nM, E_max = 2.1-fold of basal activity) and exhibits oral availability as well as blood-brain-barrier permeability in mice. Preventive treatment (10 mg/kg/12h from 7th to 23rd day post MOG_35-55 immunization) is shown to delay the onset (15 d.p.i. with & 12 d.p.i. without preventive treatment) and severity of experimental autoimmune encephalomyelitis (EAE) in a murine multiple sclerosis (MS) model in vivo, while no improvement of EAE symptoms is observed if the treatment starts after the disease onset (10 mg/kg/12h from 21 d.p.i. to 36 d.p.i.). Consistent with the known negative regulating role of Nurr1 against NF-κB pathway, preventive treatment is shown to result in significantly reduced expression of 16 NF-κB pathway genes in the spinal cord of EAE mice.
