Oral efficacy of compound 19 in mouse formalin paw test. Measurement of formalin-induced nociceptive behaviors in mice (C57BL/6 mice) following administration of vehicle (10% Tween 80; dose volume = 5 mL/kg) or rising oral doses of compound 19. Compound 19 was administered 15 min prior to formalin injection and plasma concentrations were evaluated 1.5 h postadministration. Data were analyzed using within-subject ANOVA to determine main effects and 1 sample t test to compare to vehicle (N = 8/group); **P > 0.001.
