Effects induced by compounds 6 and 11 in the tail flick (left panel) and in the formalin (right test) tests. In the tail flick test, compounds were injected i.c.v. at a dose of 0.6 nmol/10 μL. In the formalin test, compounds were injected s.c. in the dorsal surface of the hind paw, 15 min before formalin. V is for vehicle-treated animals. * is for p < 0.05; ** is for p < 0.01; *** is for p < 0.001. N = 7.
