Nimesulide is an anti-inflammatory drug (NSAID) whose preferential selectivity for cyclooxygenase-2 (COX-2) leads to fewer adverse effects. Nimesulide acts on a single metabolic pathway of the arachidonic acid cascade. Recent studies show that multi-target NSAID is an important strategy for obtaining drugs fewer adverse effects. LQFM-091 has been proposed as a molecular hybridization from nimesulide and BF-389, with the aim to inhibit two enzymes involved in arachidonic acid metabolic cascade. The aim this work was the electrochemical characterization of LQFM-091. The electrochemical analyzes were conclusive to prove that the electroactive groups are unhindered and were important in this drug action mechanism.
