Description
PA-8 is a potent, selective and orally active PACAP type I (PAC1) receptor antagonist. PA-8 inhibits the phosphorylation of CREB induced by PACAP in PAC1-, but not VPAC1- or VPAC2-receptor. PA-8 also inhibits PACAP-induced cAMP elevation with an IC50 of 2 nM.

How to use
In Vitro:
In PAC1/CHO cells, PA-8 (10 pM to 10 nM; 30 minutes) dose dependently inhibits PACAP (1 nM)-induced CREB phosphorylation. In VPAC1/CHO and VPAC2/CHO cells, PACAP (1 nM) also induced CREB phosphorylation; however, PA-8 (10 pM to 10 nM) does not inhibit PACAP (1 nM)-induced CREB phosphorylation.
In Vivo:
PA-8 (100 pmol/5 µL; intrathecal injection; once; male ddY mice) treatment inhibits PACAP-induced aversive responses and mechanical allodynia in vivo. PA-8 (3-30 mg/kg, p.o.) treatment results in the dose-dependent attenuation of the second phase of formalin-induced nociceptive responses. PA-8 also inhibits c-fos upregulation in the ipsilateral dorsal horn of the spinal cord.
