Biological Activity
Asivatrep (PAC-14028) could prevent barrier damages, accelerate skin barrier recovery and suppress pruritus, showing a potential for the treatment of atopic dermatitis. It could suppress serum IgE increase, epidermal infiltration of inflammatory cells and mast cell degranulation associated with atopic dermatitis[1]. Asivatrep (PAC-14028) shows efficacies against diverse disease models including visceral pain, inflammatory bowel disease, and inflammatory pain[2].

Solvent & Solubility
DMSO : 50 mg/mL (101.74 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (5.09 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.

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 .

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
Rats: 1 mg of Asivatrep (PAC-14028) is dissolved in 10 mL of methanol to obtain a concentration of 100 μg/mL. Male Sprague-Dawley rats/minipigs are given intravenously Asivatrep (PAC-14028) at a single dose of 1 mg/kg, orally PAC-14028 at a single dose of 10 mg/kg as a suspension in 1% methylcellulose and 0.5% Tween80, or topically a single or multiple doses of 10 mg/kg as 1% Asivatrep (PAC-14028) solution (gel form) in 68% PEG400 vehicle. For the topical application, dorsal area is shaved and painted with designated dose of Asivatrep (PAC-14028) formulation. Occlusive dressing is placed on the applied region for 6 h to withhold licking or scratching the area. Blood samples are collected from the retroorbital sinus or jugular vein into heparinized tubes at designated times after drug administration. Blood samples are centrifuged immediately, and the plasma is collected and store for analysis[1].
