A-484954 (A484954; A 484954) is a highly selective, cell-permeable and ATP-competitive eukaryotic elongation factor-2 (eEF2) inhibitor with potential antitumor activity. It inhibits eEF2 with an IC50 of 280 nM. eEF2 is a member of the GTP-binding translation elongation factor family, and an essential factor for protein synthesis and cell survival.
| ln Vitro |
In an enzymatic experiment, A-484954, a highly selective eEF2K inhibitor, has an IC50 value of 280 nM for eEF2K at concentrations that are active against a range of serine/threonine and tyrosine inhibitors. In enzymatic experiments, the IC50 value of A-484954 rises as ATP concentrations rise, although calmodulin concentrations do not change this relationship [1].

| ln Vivo |
NA precontraction in the E(+) and E(-) aorta and mesenteric arteries is caused by A484954. A-484954-induced mesenteric artery relaxation can be partially blocked by treatment with L-NAME in conjunction with methacin or cimetidine [2]. Long-term A-484954 administration prevents MCT-induced elevation of PA pressure. It was demonstrated that A-484954 inhibited MCT-induced PA fibrosis and hypertrophy, but not endothelial regulated or unregulated damage. Furthermore, A-484954 prevents ROS production, matrix metallochrome-2 activation, and MCT-induced NADPH oxidase-1 expression [3].

| Solubility (In Vitro) |
DMSO : ~25 mg/mL (~86.42 mM)
H2O : < 0.1 mg/mL |
|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.64 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2 mg/mL (6.91 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
