製品説明 | 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. |
---|---|
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] |
in vivo | BIRB 796 (30 mg/kg) inhibits 84% of TNF-α in LPS-stimulated mice and demonstrates efficacy in a mouse model of established collagen-induced arthritis. [1] BIRB 796 has good pharmacokinetic performance even after oral administration in mice. [2] |
特徴 | The first p38 MAPK inhibitor to be tested in a phase III clinical trial. |

---|---|---|
THP-1 cells are preincubated in the presence and absence of BIRB 796 for 30 min. Cell mixture is stimulated with LPS (1 μg/mL final) and incubation continued overnight (18−24 hours) as above. Supernatant is analyzed for human TNF-α by a commercially available ELISA. Data are combined and analyzed by nonlinear regression using a three parameter logistic model to obtain an EC50 value. BIRB 796 is analyzed in each experiment and the 95% confidence intervals for the EC50 are between 16 and 22 nM. | ||
