Nedocromil inhibits the release of histamine, LTC4, and PGD2 from mast cells challenged with antigen (with IC30 values of 2.1 μM, 2.3 μM, and 1.9 μM, respectively) and with anti-human IgE (IC30 values of 4.7 μM, 1.3 μM, and 1.3 μM, respectively)[1].

Solvant et solubilité
DMSO : 5.2 mg/mL (12.52 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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: ≥ 0.52 mg/mL (1.25 mM); Clear solution
This protocol yields a clear solution of ≥ 0.52 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.2 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: ≥ 0.52 mg/mL (1.25 mM); Clear solution
This protocol yields a clear solution of ≥ 0.52 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.2 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
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.
Protocole
Mice[2]
8-12 weeks old C57/BL6 male mice between 23-25 g receive intraperitoneal (i.p.) injections of 50 mg/kg Streptozotocin (STZ), dissolved in 100 mM citrate buffer pH 4.5, for five consecutive days. Diabetic mice (13-week-old) are randomly divided into three groups: 1) untreated group; 2) Nedocromil group, with Nedocromil released at the rate of 30 mg/kg per day from a subcutaneous (s.c.) pellet implantation; and vehicle group, with an inactive pellet implanted. Normal mice (non-diabetic) and normal mice that receive Nedocromil (30 mg/kg per day) are also included in this study for comparison. All sample groups included 15 mice (n=15)[2].
