General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |
||
About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Shipping Condition | Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request. |
Description | BMS-345541 free base is a selective inhibitor of the catalytic subunits of IKK (IKK-2 IC50=0.3 μM, IKK-1 IC50=4 μM). BMS-345541 binds at an allosteric site of IKK.In Vitro:BMS-345541 selectively inhibits the stimulated phosphorylation of IκBα in cells (IC50=4 μM). Consistent with the role of IKK/NF-κB in the regulation of cytokine transcription, BMS-345541 inhibits lipopolysaccharide-stimulated tumor necrosis factor α, interleukin-1β, interleukin-8, and interleukin-6 in THP-1 cells with IC50 values in the 1 to 5 μM range[1]. BMS-345541 treatment results in a concentration-dependent inhibition of melanoma cell proliferation in SK-MEL-5, A375, and Hs 294T cells. BMS-345541 (0, 100 μM) shows apoptotic features as revealed by TUNEL staining and nuclear condensation[2].In Vivo:BMS-345541 (10 mg/kg, p.o.) results in prolonged serum drug levels, with concentrations sustained at or above 1 μM for many hours in mice. BMS-345541 dose-dependently inhibits the production of TNFα measured in the serum of animals challenged with an intraperitoneal administration of LPS[1]. BMS-345541 (0, 10, 25, and 75 mg/kg, p.o.) effectively inhibits SK-MEL-5 tumor growth in a dose-dependent manner in the mice. Tumor-bearing mice treated with 75 mg/kg of BMS-345541 show effective inhibition of growth of SK-MEL-5, A375, and Hs 294T tumors by 86±2.8%, 69±11% and 67±3.4%, respectively[2]. References: |

BMS-345541(free base) is a selective inhibitor of IKK-1 and IKK-2 with IC50 value of 4μM and 0.3μM, respectively [1].
IKK is also known as nuclear factor kappa-B kinase subunit inhibitor and involves in cytokine-activated intracellular signaling pathways. IKK-1 and IKK-2 are members of IKK family. It has been reported that IKK-2 plays a pivotal role in brain cells following a stroke [2] [3].
BMS-345541 is a potent IKK inhibitor and has a highly selective activity compared with other kinases. When tested with THP-1 monocytic cells, pre-incubation with BMS-345541 inhibited TNF-α-stimulated IKK phosphorylation and reduced a variety of cytokines production including TNF-α, IL-1β, IL-8, and IL-6 [1]. In 4 human glioma cell lines, BMS-345541 treatment significantly blocked cell proliferation (80%-95%) at the concentration of 10 μM or higher and also inhibited IL-8 expression in a dose dependent manner (IC50>2 μM) [2]. And similar result of BMS-34551 inhibition on IKK which induced cell apoptosis was verified in human melanoma cell lines SK-MEL-5, Hs 294T, and A375 [3].
In 18-22g female BALB/c mice model, administration of BMS-345541 inhibited TNF-αproduction in a dose-dependent manner, ~50% inhibition was seen when used the concentration of 10 mg/kg and near complete inhibition was seen at a dose of 100 mg/kg [1].
