GEA 3162
Based on 1 Customer Validation
GEA 3162 is an orally active compound that acts as a NO/ONOO⁻ donor. GEA 3162 significantly inhibits the activation of human polymorphonuclear leukocytes (PMNs) through the cGMP pathway, inhibits the release of inflammatory mediators, and exerts anti-inflammatory and protective effects. GEA 3162 induces apoptosis of neutrophils and bone marrow cells by activating caspase-2/3/8/9 through the ONOO⁻ pathway. GEA 3162 has a bidirectional effect in the rat gastric ulcer model: at low doses, it significantly reduces gastric mucosal damage, while at high doses, it aggravates the ulcer area. GEA 3162 can be used for research on inflammatory conditions such as gastric ulcers.

GEA 3162 (1-100 μM) inhibits Ca ionophore A23187-induced LTB4 and beta-glucuronidase release, chemotactic peptide FMLP-induced chemotaxis and opsonized zymosan-triggered chemiluminescence dose-dependently in human PMNs[1].
GEA 3162 (0-1 mM) inhibits LTB4 release from human PMNs dose-dependently[1].
GEA 3162 (0-1 mM) suppresses β-glucuronidase release from A23187-activated PMNs dose-dependently[1].
GEA 3162 (0-1 mM) is effective inhibitor of FMLP-induced chemotactic movement of human PMNs with IC50 value of 6 μM[1].
GEA 3162 increases the cyclic GMP levels more rapidly and at lower drug concentrations[1].

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 (10.82 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 (10.82 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.
