A. Effects of VBA-AP, Benzo-AP or AP (1000 nM AP), VBA-Ø or Benzo-Ø on VFF withdrawal responses (mechanical allodynia) of contralateral paw. B, C. Effects of VBA-AP, Benzo-AP, PFPA-AP, AP (1000 nM AP), VBA-Ø, Benzo-Ø or PFPA-Ø on VFF withdrawal responses of ipsilateral paw. B shows time course and C shows AUC. D. Comparison between AP and AP-NH2 in SNI mice. E,F. Effects of VBA-AP, Benzo-AP, AP (1000 nM AP), VBA-Ø or Benzo-Ø on acetone withdrawal responses (cold allodynia) of ipsilateral paw in SNI mice.
