SB 203580 inhibits IL-2-driven T cell proliferation with an IC50 of 3-5 μM, SB 203580 is able to inhibit the activity of PDK1 in a dose-dependent manner with an IC50 in the 3-10 μM range[1]. SB 203580 at a concentration of 1 μM is sufficient for inhibiting p38 kinase activity in TF-1 cells. SB 203580 at 5 and 10 μM enhances NF-κB-mediated gene transcription independently of phosphorylation on the transactivation domains of the p65 subunit. SB 203580 at 10 μM enhances phosphorylation of ERK1/2 and JNK[1].
SB 203580 decreases protein concentrations of IL-1β from 106.49±10.93 to 67.85±7.39 pg/mL and TNF-α from 462.54±50.16 to 252.71±44.03 pg/mL. Similarly, the protein levels of MMP-2 and MMP-9 are significantly lower in the SB 203580 than the EM group. After treatment with SB 203580, the protein levels of MMP-2 and MMP-9 decreases from 2.70±0.14 to 1.74±0.26 ng/mL and from 3.17±0.31 to 1.98±0.24 ng/mL, respectively[3]. SB 203580 is evaluated in several models of cytokine inhibition and inflammatory disease. It is demonstrated clearly to be a potent inhibitor of inflammatory cytokine production in both mice and rats with IC50 values of 15 to 25 mg/kg[4].
