Description：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. Edicotinib limits microglial expansion and attenuates microglial proliferation and neurodegeneration in mice. Edicotinib has the potential for Alzheimer’s disease and rheumatoid arthritis research.

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].

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].

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