Background:

SB202190 (FHPI) is a potent p38 MAPK inhibitor that specifically inhibits p38α and p38β with IC50 values of 50 and 100 nM, respectively [1].

SB202190 has been reported to potently enhance the growth of leukemia cell lines THP-1 and MV4-11. SB202190 activates the phosphorylation ERK and C-Raf. Studies have shown that the ED50?values of U0126 and FPT inhibitor II were significantly decreased in the presence of SB202190 [2].

SB202190 triggers changes in cell cycle profiles both during HU treatment and caffeine-induced PCC?(premature chromosome condensation) in plants. Moreover, SB202190 and caffeine decrease independently HU-induced histone H4 Lys5 acetylation [3].
