MDA-MB-231 or T47D cells were pretreated with 300 nM NH125 for 1 h, followed by treatment with 8 μM TBMS1 for 24 h. The protein levels were measured by Western blot.

NH125 sensitizes NPC cells to lapatinib. NPC cells were treated with lapatinib or DMSO for 48 h in the presence or absence of 0.25 μM NH125. Cell viability was assessed by the CCK-8 assay. Results are expressed as means±standard deviation. *, P<0.05;**, P<0.01 and ***, P<0.001.

CNE-2 cultured in medium supplemented with 10% FBS was treated with a series of concentrations of MK-2206 for 72 hours in the presence or absence of 20 μM HCQ and 0.25 μM NH125. Cleaved caspase-3 was measured by Western blotting, and β-actin was used as a loading control.

|Description||NH125 is a selective eEF-2 kinase inhibitor with IC50 of 60 nM, >125-fold selectivity over PKC, PKA, and CaMKII, and also a potent histidine kinase inhibitor.|
In C6 glioma cells, NH125 decreases the cellular content of phospho-eEF-2 without affecting total content eEF-2 content, and blocks cell cycle transit at the G1-S boundary. NH125 potently inhibits cell viability of 10 cancer cells with IC50 ranging from 0.7 to 4.8 μM.  NH125 effectively inhibits histidine protein kinases, including Envz, PhoQ, BvgS, EvgS, and thus produces potent anti-bacteria activities on oxacillin-resistant Staphylococcus aureus (ORSA), vancomycin-resistant Enterococcus faecalis (VRE), penicillin-resistant Streptococcus pneumoniae (PRS), and other Gram-positive and Gram-negative bacteria.  EEF2K inhibition by NH125 renders tumor cells more sensitive to curcumin and velcade, which possess ER stress-inducing action. 
|In vivo||NH125 reduces blood pressure in SHR and ROS production, induction of inflammatory molecules, and hypertrophy in SHR superior mesenteric artery. |
eEF-2 Kinase Assay:eEF-2 kinase activity is measured by two methods: (a) a filter-based assay; and (b) by immunoblotting using antiphospho-eEF2 antibody. For both of these, reactions are carried out in 20 μl of total volume containing 50 mM HEPES (pH 7.5), 10 mM MgCl2, 1.5 mM CaCl2, 100 μg/ml calmodulin, 2 μM His-tagged eEF-2 and 400 nM GST-eEF-2 kinase, and ATP mixture [50 μM ATP with 1μCi (γ-33P)ATP]. The kinase mixture without ATP is prepared on ice and then preincubated for 15 min at room temperature. Kinase reactions are started by adding ATP and allowed to progress at 30°C for 30 min. For the filter-based assay, the reaction is terminated by adding 20 μl of cold 1.5% phosphoric acid, and 5 μl of the reaction are applied to P81 Whatman phosphocellulose paper. The paper is washed three times in 500 ml of 0.5% phosphoric acid and once with 200 ml of acetone. The paper is then air-dried and immersed in 10 ml of scintillation mixture. Radioactivity is counted using a Beckton-Dickinson liquid scintillation counter. For immunoblotting, the reactions are stopped by addition of 20 μl of 3× Lamelli buffer [190 mM Tris (pH 6.8), 6% SDS, 30% glycerol, 15% 2-mercaptoethanol, and 0.003% bromphenol blue dye]. Samples are boiled for 5 min and resolved by 7% SDS-PAGE and processed for Western blotting as described below. Conditions for both assays are chosen to ensure linearity of the reaction with respect to time of incubation and concentration of enzyme.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
