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].

Animal Administration

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.
