After pre-incubation with serial dilutions of test compound (0.25% v/v DMSO final) for 30 min at 37 °C, cells were stimulated with the addition of IFNγ (10 ng/ml) and lipopolysaccharide (LPS) (5 μg/ml) per well and incubated for 3 h at 37 °C. Following a brief centrifugation, supernatant (10 μl) sample from each well was quantified against TNFα calibration curve using HTRF TNFα kit (CisBio).

Cells were washed, prior to incubation with secondary goat anti-rabbit IgG ALEXA (fluor) 647-conjugated antibody diluted 1:5000 in wash buffer (50 μl/well) for 60 min at room temperature in the dark. Cells were washed as described above, prior to careful resuspension in wash buffer (50 μl) for FACS (fluorescence activated cell sorting) analysis. Cells were transferred to 'V' bottom 96-well plates and analysed using a FACSCalibur™ cytometer (Becton Dickinson) equipped with red-diode laser (excitation 635 nm). Gating of cells according to forward and side scatter, mean fluorescent intensity (MFI) was calculated at 653-669 nm (emission).

    • The MK2 compound was administered po to OF1 mice (female, 8 weeks old), followed by LPS injection (20 mg/kg) 1 h later. 1 h post LPS injection the experiment was terminated and blood withdrawn. Compound blood levels were determined by LC-MS/MS and plasma levels of mouse TNFα determined by ELISA.
