生物活性

Edicotinib (JNJ-40346527) is a potent, selective, brain penetrant and orally active colony-stimulating factor-1 receptor (CSF-1R) inhibitor with an IC50 of 3.2 nM. Edicotinib exhibits less inhibitory effects on KIT and FLT3 with IC50 values of 20 nM and 190 nM, respectively[1]. Edicotinib limits microglial expansion and attenuates microglial proliferation and neurodegeneration in mice. Edicotinib has the potential for Alzheimer’s disease and rheumatoid arthritis research[1][2].

IC50 & Target

IC50: 3.2 nM (CSF-1R)[1]
20 nM (KIT); 190 nM (FLT3)[2]

体外研究
(In Vitro)

Edicotinib (0.1 nM-1μM; 24 hours) Leads to a dose-dependent decrease of CSF1R activation and a concurrent reduction of ERK1 and ERK2 phosphorylation. The dose response curve shows the effect of JNJ-527 on CSF1R and ERK1/2, and the IC50 values are 18.6 nM and 22.5 nM for CSF1R and ERK1/2, respectively[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[1]

Cell Line: N13 microglial cells
Concentration: 0.1 nM, 1 nM, 10 nM, 100 nM, 1000 nM
Incubation Time: 24 hours
Result: Prevented CSF1R and ERK1/2 phosphorylation in N13 microglial cells
体内研究
(In Vivo)

Edicotinib (oral gavage; 3, 10, 30 and 100 mg/kg; 5 days) significantly inhibits microglial proliferation in ME7 mice. It diminishes the number of microglia (total CD45+CD11b+ cells) only at the highest dose tested of 100 mg/kg, and JNJ-527 depletes up to 50% of patrolling blood monocytes at every dose tested (CD45+CD11bhighLy6Cintermediate/lowcells) with only a tendency for a reduction in the proportion of inflammatory monocytes (Ly6C high cells) at 100 mg/kg[1].
Edicotinib exhibits a good pharmacokinetic/pharmacodynamics (PK/PD) profile, the microglial proliferation data shows an EC50 of 196/ml and 69 ng/g calculated from plasmatic and brain compound concentration, respectively[1].
Edicotinib (oral gavage; 30 mg/kg; 33 days) significantly reduces the density of microglia in CA1 of the hippocampus of ME7-prion mice (PU.1+ cells) by up to 30%. And the expression of IL-1β is also reduced,but not other inflammatory cytokines[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6 J (Harlan) mice[1] 
Dosage: 3, 10, 30 and 100 mg/kg; 5 days
Administration: Oral gavage
Result: Did not affect microglial numbers when administered under 100 mg/kg.
Animal Model: C57BL/6 J (Harlan) mice[1] 
Dosage: 30 mg/kg; 33 days
Administration: Oral gavage
Result: Limited microglial expansion and attenuated behavioural deficits in ME7-prion mice.
