The present study was designed to examine the antinociceptive and anti-inflammatory effects of 7-chloro-4-phenylsulfonyl quinoline (PSOQ). Mice were orally (p.o) pretreated with PSOQ (0.01–10 mg/kg), meloxicam (10 mg/kg), 30 min prior to the acetic acid, hot-plate and open field tests. PSOQ reduced abdominal writhing induced by acetic acid, while meloxicam presented no effect. The latency time in the hot-plate test and locomotor/exploratory activities in the open field test were not altered by treatments. In order to evaluate the gastric tolerability after oral administration of PSOQ or meloxicam (10 mg/kg), mice were fasted for 18 h prior to drug exposure. Four hours later, the development of lesions was assessed. PSOQ and meloxicam did not induce ulcer at the dose and time evaluated. Indeed, anti-inflammatory and anti-edematogenic properties of PSOQ were investigated. For this, animals were pretreated with PSOQ (0.01–50 mg/kg; p.o.), meloxicam (50 mg/kg; p.o.), 30 min prior to croton oil application. PSOQ and meloxicam (50 mg/kg) diminished the edema formation and myeloperoxidase activity induced by croton oil in the ear tissue. Taken together these data demonstrated that PSOQ exerts acute anti-inflammatory and antinociceptive actions, suggesting that it may represent an alternative in the development of future new therapeutic strategies.
