Description: | 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. PAC-14028 shows efficacies against diverse disease models including visceral pain, inflammatory bowel disease, and inflammatory pain.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 PAC-14028 is relatively well-absorbed through oral route. 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. |
