Abstract

Advances have been made in the search for new multi-target modulators to control pain and inflammation. Therefore, compound 3,5-di-tert-butyl-4-hydroxyphenyl)(4-methylpiperazin-1-yl)methanone (LQFM202) was synthesised and evaluated. First, in vitro assays were performed for COX-1, COX-2, and 5-LOX enzymes. Subsequently, adult female Swiss albino mice treated orally with LQFM202 at doses of 25–200 mg/kg were subjected to acetic acid-induced writhing, formalin-induced pain, carrageenan-induced hyperalgesia, carrageenan- or zymosan-induced paw oedema, or pleurisy. LQFM202 inhibited COX-1, COX-2, and LOX-5 (IC50 = 3499 µM, 1565 µM, and 1343 µM, respectively). In acute animal models, LQFM202 (50, 100, or 200 mg/kg) decreased the amount of abdominal writhing (29%, 52% and 48%, respectively). Pain in the second phase of the formalin test was reduced by 46% with intermediate dose. LQFM202 (100 mg/kg) reduced the difference in nociceptive threshold in all 4 h evaluated (46%, 37%, 30%, and 26%, respectively). LQFM202 (50 mg/kg) decreased the carrageenan-oedema from the second hour (27%, 31% and 25%, respectively); however, LQFM202 (100 mg/kg) decreased the carrageenan-oedema in all hours evaluated (35%, 42%, 48% and 50%, respectively). When using zymosan, LQFM202 (50 mg/kg) decreased the oedema in all hours evaluated (33%, 32%, 31% and 20%, respectively). In the carrageenan-pleurisy test, LQFM202 (50 mg/kg) reduced significantly the number of polymorphonuclear cells (34%), the myeloperoxidase activity (53%), TNF-α levels (47%), and IL-1β levels (58.8%). When using zymosan, LQFM202 (50 mg/kg) reduced the number of polymorphonuclear and mononuclear cells (54% and 79%, respectively); and the myeloperoxidase activity (46%). These results suggest antinociceptive and anti-inflammatory effects of LQFM202.
