Mechanism of Action

Features	The first p38 MAPK inhibitor to be tested in a phase III clinical trial.
Targets/IC₅₀/Ki	JNK2 c-RAF Fyn p38α (Cell-free assay) 0.1 nM(Kd) p38α 38 nM
In vitro	Doramapimod (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. This compound greatly improves binding affinity by forming a hydrogen bond between the morpholine oxygen and the ATP-binding domain of p38α. It represents one of the most potent and slowest dissociating inhibitors against human p38 MAP kinase now known. It potently inhibits c-Raf-1 and Jnk2α2 with IC50 of 1.4 and 0.1 nM, respectively. BIRB796 also inhibits the activity and the activation of SAPK3/p38γ at a higher concentration than it does in p38α. It blocks the stress-induced phosphorylation of the scaffold protein SAP97, which is a physiological substrate of SAPK3/p38γ. This compound 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. It blocks baseline and upregulation of p38 MAPK and Hsp27 phosphorylation, thereby enhancing cytotoxicity and caspase activation. This compound downregulates IL-6 and VEGF secretion in BMSCs triggered by TNF-α and TGF-β1. It 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. This compound also inhibits B-Raf and Abl with IC50 of 83 nM and 14.6 μM, respectively.
Kinase Assay	Procedures for the THP-1 cellular assay for inhibition of LPS-stimulated TNF-α production
Kinase Assay	THP-1 cells are preincubated in the presence and absence of Doramapimod (BIRB 796) for 30 min. The 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. This compound is analyzed in each experiment and the 95% confidence intervals for the EC50 are between 16 and 22 nM.
In vivo	Doramapimod (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. This compound has good pharmacokinetic performance even after oral administration in mice.
