生物活性
PA-8 是一種有效的，選擇性的，具有口服活性的 PACAP I 型 (PAC1) 受體拮抗劑。PA-8 抑制 PAC1受體中 PACAP 誘導(dǎo)的 CREB 的磷酸化，但不抑制 VPAC1 或 VPAC2 受體。PA-8 還抑制 PACAP 誘導(dǎo)的 cAMP 升高，IC50 為 2 nM。體外研究
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.
體內(nèi)研究
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.
| Animal Model: | Male ddY mice (6 weeks old) injected with PACAP (100 pmol) |
| Dosage: | 100 pmol/5 μL |
| Administration: | Intrathecal injection; once |
| Result: | Inhibited PACAP-induced aversive responses and mechanical allodynia in vivo. |
