Apafant
Based on 3 publication(s) in Google Scholar
Apafant (WEB 2086), a chemical probe, is a potent platelet-activating factor (PAF) antagonist, inhibits PAF binding to human PAF receptors with a Ki of 9.9 nM. Apafant increases the gene expression of PAF-r, α-globin, β-globin, decreases the c-myb gene expression. Apafant shows a protective effect on alkyl-PAF-mediated lethalit.

Ki: 9.9 nM (Platelet-activating factor)[1]
Apafant (1 mM; 5 days) increases the gene expression of PAF-r, α-globin, β-globin, and decreases the c-myb gene expression in murine erythroleukemia cells (MELCs)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Murine erythroleukemia cells (MELCs)
-
Concentration:1 mM
-
Incubation Time:5 days
-
Result:Iecreased the gene expression of PAF-r, α-globin, β-globin, decreased the c-myb gene expression.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:20-25 g, Swiss albino mice[3]
-
Dosage:1, 5, 10, 20, 30 mg/kg (3 h later, challenged with a lethal dose of alkyl-PAF (250 μg/kg); ip)
-
Administration:IP; once
-
Result:Increased mouse survival with none of the mice died when they were pretreated with WEB-2086 and then challenged with a lethal dose of alkyl-PAF 5 h later, Only 17% died when challenged 10 h after the WEB-2086 pretreatment. Even in the groups that received the alkyl-PAF injection 30 or 45 h after the WEB-2086 pretreatment, 33% of the mice still survived.

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: ≥ 5 mg/mL (10.97 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (10.97 mM); Clear solution

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
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.
