Biological Activity
| ln Vitro | eIF4A3-IN-2 (Compound 2) binds to the allosteric region of eIF4A3 and, in vitro, inhibits the activities of ATPase, helicase, and cellular nonsense-mediated RNA decay (NMD) [1]. |
| Cell Assay |
Apoptosis analysis [1] Cell Types: HEK293T cells (transfected with NMD reporter gene) Luciferase assay Tested Concentrations: 0.3, 1, 3 or 10 μM Incubation Duration: 3 or 6 hrs (hours) Experimental Results: eIF4A3-IN-2 induces apoptosis The luciferase activity increased approximately 3.2 times, indicating that NMD was inhibited by compound 2[1]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~165.92 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (4.15 mM) in 5% DMSO + 40% PEG300 + 5% Tween80 + 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1.67 mg/mL (2.77 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 16.7 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 3: ≥ 1.67 mg/mL (2.77 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 16.7 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.) |
