Why the expression of phospho-p38 was increased in SH-SY5Y cell treated with SB203580? Isn’t the role of SB203580 is to block p38 phosphorylation?

Although we used p38 inhibitor (SB203580) why the expression of phosphorylated-p38 was increased in SH-SY5Y cell treated with SB203580? Isn’t the role of SB203580 is to block the phosphorylation...
