TLR4 18.5 μM (EC50) |
Neoseptin 3 is a Toll-like receptor 4/myeloid differentiation factor 2 (mTLR4/MD-2) agonist with an EC50 of 18.5 μM. Neoseptin-3 induces TNFα production by macrophages in a concentration-dependent manner. Neoseptin-3 induces phosphorylation of IκB kinases α (IKKα), IKKβ, p38, c-Jun N-terminal kinase (JNK), and ERK, and degradation of IκBα, consistent with activation of MAPK and canonical NF-κB signaling. TANK-binding kinase 1 (TBK1) and IRF3 phosphorylation also increase in response to Neoseptin-3[1].

Solvent & Solubility
DMSO : ≥ 100 mg/mL (210.71 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.27 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.27 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
HEK293T cells are transfected with an NF-κB-dependent luciferase reporter plasmid and clones with stable expression are selected by culture in DMEM containing puromycin. Cells are cotransfected with constructs for mouse or human TLR4 plus mouse or human MD-2, and 2 d later are stimulated with 50 μM Neoseptin-3 or 1 μg/mL LPS for 6 h. Cells are lysed, and luciferase activity is measured[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Cells are seeded onto 96-well plates at 1×105 cells per well and stimulated with Neoseptin-3 [dissolved in DMSO; final DMSO concentrations (≤0.2%) are kept constant in all experiments] for 4 h. Mouse TNFα, IL-6, or IFN-β, or human TNFα in the supernatants are measured by ELISA kits according to the manufacturer’s instructions. Unless otherwise indicated, mouse cells are from wild-type C57BL/6J mice[1].
