Bay 65-1942 HCl is the hydrochloride salt of of BAY65-1942 which is a novel, potent and selective ATP-competitive inhibitor of IKKβ.It targets the IKKbeta kinase activity specifically. Following an acute ischemia-reperfusion injury, IKKbeta inhibition reduces myocardial damage and dysfunction. The CK-MB levels of the animals pretreated with Bay 65-1942 (n=3) were significantly lower than those of the untreated animals before IR (14,170 ±3,219 units, P<0.05 vs. vehicle).

Compared to animals receiving a vehicle, the size of the left ventricular infarct is significantly reduced when Bay 65-1942 is administered before ischemia. Animals receiving vehicles have a significantly higher infarct-to-area at risk (AAR) ratio than sham animals (70.7±3.4 vs. 5.8±3.4%, P<0.05). Treatment with Bay 65-1942 at each time point significantly lowers this ratio (prior to ischemia 42.7±4.1%, at reperfusion 42.7±7.5%, 2 hours after reperfusion 29.4±5.2%; each group P<0.05 vs. vehicle). The CK-MB levels in the animals pretreated with Bay 65-1942 (n=3) were significantly lower than those in the control group before IR (14,170 ±3,219 units, P<0.05 vs. vehicle)[1].

| ln Vivo |
In order to sufficiently inhibit kinase activity, inhibitors of MEK (AZD6244) and IKK (BAY 65-1942) are used at their IC50 concentrations, as determined by a 48-hour MTS assay. AZD6244 (5 µM), BAY 65-1942 (10 µM), or a combination of these inhibitors at the same concentrations are applied to MYL-R cells for 24 hours. At the dose combination of (5 µM AZD6244+10 µM BAY 65-1942), which correlates with IC75 (CI = 0.48±0.01), AZD6244 and BAY 65-1942 show synergistic inhibition of cell viability. Additionally, the software reports that synergism is present at the IC50 (CI = 0.56±0.09) and IC90 (CI = 0.460.02) dose combinations (CI values are the mean of three independent experiments, ±standard deviation). In comparison to DMSO-treated cells, the effects of AZD6244 and BAY 65-1942 on caspase 3/7 activation are 1.3 and 2 times greater, respectively. Caspase 3/7 activity is 3.2 times higher after treatment with AZD6244 and BAY 65-1942[2].

| Cell Assay |
MYL-R cells are plated on a 96-well plate at a density of 4×104 cells/well in a growth medium of 100 µL RPMI containing kinase inhibitors to test the viability of the cells. During the first 24 and second 48 hours, growth media and kinase inhibitors are replenished. Each well is filled with 20 L of the MTS assay reagent. The absorbance at 490 nm is measured after the plate has been in the incubator for roughly an hour. Cells are cultivated and tested for combination index (CI) experiments. Cells are treated with a series of three-fold dilutions of either AZD6244 alone or in combination with BAY 65-1942 (10 µM) while maintaining a constant ratio of 1:2, respectively, to ascertain the dose-effects of each drug. To calculate CI values, cell viability test results are analyzed. Three independent experiments' CI values are averaged[2].

| Animal Protocol |
Mice: 8–10 week-old male C57BL/6 mice are used. Mice are given 30 minutes of cardiac ischemia followed by various amounts of reperfusion in order to study the effects of IKK inhibition on myocardial IR injury. At the proper dosing times, Bay 65-1942 (5 mg/kg) is injected intraperitoneally. A 10% cremaphor in water vehicle is given to non-treatment groups. In treatment groups, Bay 65-1942 is administered either before ischemia, during reperfusion, or two hours after reperfusion injury. The size of the infarct is determined 24 hours after the injury caused by the reperfusion in the vehicle, sham, and treatment groups. Serum creatine kinase-muscle-brain fraction (CK-MB) levels are assessed 1 hour after reperfusion in animals that have received Bay 65-1942 treatment in order to confirm myocardial injury.
