Biological Activity

BIRB 796 (Doramapimod) is a protein kinase inhibitor of p38 MAPK. BIRB 796 (Doramapimod) has high picomolar affinity (Kd = 100 pM) for p38 MAP kinase and low nanomolar inhibitory activity (IC50 = 18 nM) against TNFα in THP-1 cell culture. The p38 inhibitor BIRB 796 (Doramapimod) binds tightly (Kd = 40 nM) to ABL (T315I) and inhibits the BMS-354825- and imatinib-resistant ABL (T315I) kinase.

Customer Product Validations & Biological Datas
Source PLoS One (2013). Figure 4. BIRB796
Method Western blot
Cell Lines MDR cells
Concentrations 10 μM
Incubation Time 72 h
Results These data indicated that BIRB796 mediated the reversal of MDR by inhibiting the function of ABCB1, and not due to inhibition of ABCB1 expression.
Cell Experiment
Cell lines MM derived cell line
Preparation method Growth inhibition assay. The growth inhibitory effect of BIRB 796 on MM cell line growth was assessed by measuring 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrasodium bromide (MTT, Sigma Chem-ical) dye absorbance, as previously described (Yasui et al,2005a)
Concentrations 0, 100, 400nM
Incubation time 72h
Animal Experiment
Animal models Male Crlj:CD1(ICR)mice
Formulation saline
Dosages 250, 500 or 1000 mg/kg
Administration oral

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
