Description

Asivatrep (PAC-14028) is a potent and selective transient receptor potential vanilloid type I (TRPV1) antagonist.

In Vitro

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].

In Vivo

Asivatrep (PAC-14028) shows a plasma half-life of 2.1 h in rats while it is extended slightly to 3.8 h in minipigs. Oral bioavailability at 10 mg/kg dose is determined to be 52.7% and 64.2% in rats and minipigs, respectively suggesting that Asivatrep (PAC-14028) is relatively well-absorbed through oral route[1]. Asivatrep (PAC-14028) could inhibit capsaicin-evoked calcium influx in keratinocytes at sub-micromolar concentrations. This potent TRPV1 antagonistic activity in keratinocytes is manifested in vivo as the blockade of capsaicin-induced blood perfusion increase, and the accelerated barrier recovery from tape-stripping-induced barrier damages in hairless mice[3].

In Vivo:

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.

  • Protocol 1

    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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.09 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Animal Administration
[1]

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
