  • A p38α/ERK crosstalk exists in CRC cells and tissues. Use of a structurally and functionally different p38α inhibitor (BIRB-796) confirms ERK1/2 phospho-activation. Using BIRB-796 for up to 72 h triggers MEK-ERK1/2 signaling in HT-29 cells.

    Inhibition of p38 MAPK activity prevents induction of autophagy by glucose. NIH 3T3 cells were incubated in KH medium without glucose in the presence of the p38 MAPK inhibitor BIRB796 (50 nM, middle panels). After 30 min, glucose (10 mM) and lysosomal inhibitors were added to the indicated samples and cells were further incubated for 2 h. Cell lysates were collected and processed for SDS/PAGE. LC3 levels were detected and actin served as a loading control. The values shown in the histograms represent means盨.D. from three independent experiments with the LC3-II levels normalized to actin and expressed as a percentage of the values of KH medium without glucose. *P<0.05.

Biological Activity

Description Doramapimod (BIRB 796) is a pan-p38 MAPK inhibitor with IC50 of 38 nM, 65 nM, 200 nM and 520 nM for p38α/β/γ/δ in cell-free assays, and binds p38α with Kd of 0.1 nM in THP-1 cells, 330-fold greater selectivity versus JNK2, weak inhibition for c-RAF, Fyn and Lck, insignificant inhibition of ERK-1, SYK, IKK2.
Features The first p38 MAPK inhibitor to be tested in a phase III clinical trial.
p38α [1]
(Cell-free assay)
p38α [7]
0.1 nM(Kd) 38 nM
In vitro

BIRB 796 shows no significant inhibition to ERK-1, SYK, IKK2β, ZAP-70, EGF receptor kinase, HER2, protein kinase A (PKA), PKC, PKC-α, PKC-β (I and II) and PKC-γ. BIRB 796 greatly improves binding affinity by forming a hydrogen bond between the morpholine oxygen and the ATP-binding domain of p38α. BIRB 796 represents one of the most potent and slowest dissociating inhibitors against human p38 MAP kinase now known. [1] BIRB 796 potently inhibits c-Raf-1 and Jnk2α2 with IC50 of 1.4 and 0.1 nM, respectively. [2] BIRB796 also inhibits the activity and the activation of SAPK3/p38γ at a higher concentration than it does in p38α. BIRB796 blocks the stress-induced phosphorylation of the scaffold protein SAP97, which is a physiological substrate of SAPK3/p38γ. BIRB796 blocks JNK1/2 activation and activity in HEK293 cells, while not inhibits the activation and activity of ERK1/ERK2 in Hela cells. Moreover, the binding of BIRB796 to the p38 MAPKs or JNK1/2 is impairing their phosphorylation by the upstream kinase MKK6 or MKK4 rather than enhancing their dephosphorylation. [3] BIRB 796 blocks baseline and bortezomib-triggered upregulation of p38 MAPK and Hsp27 phosphorylation, thereby enhancing cytotoxicity and caspase activation. BIRB 796 downregulates IL-6 and VEGF secretion in BMSCs triggered by TNF-α and TGF-β1. [4] BIRB-796 has a pyrazole scaffold that places a lipophilic t-butyl group into the lower selectivity site and a tolyl ring into the upper selectivity site. BIRB-796 also inhibits B-Raf and Abl with IC50 of 83 nM and 14.6 μM, respectively. [5]
