    Effects of Peficitinib on IL-6 and IL-6R responses in RA FLS. The RA FLS are stimulated with IL-6 (100 ng/mL) and IL-6R (100 ng/mL) after treating with Peficitinib (0.1, 1, 5 μM) for 24 h. Representative western blot images showed that peficitinib suppressed the phosphorylation of STAT1, STAT3, and STAT5 in RA FLS.

    Description

    Peficitinib is an oral JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively.

    IC50 & Target[1]

    JAK3

    0.7 nM (IC50)

    JAK1

    3.9 nM (IC50)

    Tyk2

    4.8 nM (IC50)

    JAK2

    5 nM (IC50)

    In Vitro

    Peficitinib is an oral JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. Peficitinib inhibits IL-2-induced T cell proliferation with an IC50 of 10 nM. Peficitinib also suppresses the IL-2-induced STAT5 phosphorylation in rat and human whole blood, with mean IC50s of 124 nM and 127 nM, respectively[1].

    In Vivo

    Peficitinib (20 mg/kg, p.o.) suppresses IL-2-induced STAT5 phosphorylation by 78% in the rat model of adjuvant-induced arthritis (AIA). Peficitinib potently inhibits the increase in paw volume (≥1 mg/kg) with an ED50 of 2.7 mg/kg, significantly reduces the bone destruction score (≥10 mg/kg) and almost fully ameliorates both paw swelling and bone destruction scores (30 mg/kg)[1].

    Kinase Assay
    [1]

    Human JAK1, JAK2, JAK3, TYK2-domains assays performed using streptavidin-coated 96-well plates. Reaction mixture contained 15 mM Tris-HCl (pH 7.5), 0.01% Tween 20, 2 mM dithiothreitol, 10 mM MgCl2, 250 nM Biotin-Lyn-Substrate-2 (for JAK1, 2 and 3) or Biotin-IRS1-Substrate (for TYK2), and ATP (at final concentrations of 200 μM [JAK1], 10 μM [JAK2], 8 μM [JAK3], and 4 μM [TYK2]). Peficitinib or tofacitinib is dissolved in DMSO. The reaction is initiated by adding the kinase domain, followed by incubation at room temperature for 1 h. Kinase activity is measured as the rate of phosphorylation of Biotin-Lyn-Substrate-2 or Biotin-IRS-Substrate using HRP-conjugated anti-phosphotyrosine antibody (HRP-PY-20) using a phosphotyrosine-specific ELISA. TYK2 kinase assay of Peficitinib is performed with the ATP concentration of 10 μM[1].

    Cell Assay
    [1]

    Splenocytes from male Lewis rats are suspended in RPMI1640 supplemented with 10% fetal bovine serum and 50 μM 2-mercaptoethanol at a density of 1.5 × 106 cells/mL. Rat splenocytes are cultured with Concanavalin A for 24 h at 37°C to induce IL-2 receptor expression. Splenocytes are then incubated with IL-2 and Peficitinib or tofacitinib at designated concentrations in 96-well tissue culture plates. After 3-day incubation, alamarBlue® is added to each of the test wells, followed by 4-6 h incubation. Fluorescence intensity is measured at an excitation wavelength of 545 nm and an emission wavelength of 590 nm. All experiments are performed in triplicate, and experiments are performed either four times or once for assays using Peficitinib or tofacitinib, respectively. For each individual, wells cultured with cells and medium alone are prepared for the blanks, and IL-2 stimulated cells without JAK inhibitors are prepared for the controls. To calculate the % inhibition of JAK inhibitors, blanks and controls are designated as 100% and 0% inhibition, respectively[1].

    Animal Administration
    [1]

    Rats[1]
    Seven-weeks-old female Lewis rats are used for the adjuvant-induced arthritis (AIA) model. Body weight and left hind paw volume of each rat are measured (MK-101PR volume meter), and the values are used to assign animals to one of six groups (n = 10). Arthritis is induced on day 0 in five of these groups by injecting a suspension of Mycobacterium tuberculosis H37 RA strain (0.5 mg/rat) in liquid paraffin into the right hind foot pad. The remaining group is not injected with adjuvant (normal group, n = 10). For the oral administration regimen, four of the adjuvant-injected groups receive Peficitinib (1, 3, 10, and 30 mg/kg) dissolved in 0.5% methylcellulose (MC) once daily. Rats in the normal and control groups receive 0.5% MC alone[1].
