Pain is growing to be a massive health issue across the globe. It is reported that one in every five adults tends to suffer from pain worldwide each year, regardless of age and gender. Inflammation caused by tissue damage, chemical stimulus, and foreign substances is commonly associated with pain. Inflammatory pain is mainly caused by the direct effect of inflammatory mediators on particular classes of nociceptive neurons. In the current investigation, the antinociceptive and anti-inflammatory effect of corynoline, a phytochemical compound isolated from Corydalis bungeana Turcz., has been evaluated in experimental mice. The experimental mice were divided into 5 groups of 6 animals each. The first control group was fed with water. The second, third, and fourth groups received different doses of corynoline and the fifth group of mice received positive controls. Nociception was induced with the help of acetic acid, formalin, glutamate, capsaicin, hot plate, and tail immersion in mice whereas carrageenan was used to induce inflammation. The peritoneal cavity leukocyte infiltration and pro-inflammatory mediator generation were also analyzed to confirm the anti-inflammatory effect and the natural locomotor activity was determined using an open field test. Corynoline treatment significantly suppressed the paw licking, writhing in the abdominal region, and displayed high nociceptive inhibitory reaction in a dose-related manner. Additionally, corynoline significantly reduced the carrageenan-triggered paw edema and also reduced the levels of pro-inflammatory cytokines. Thus, the antinociceptive and anti-inflammatory activity of corynoline has been successfully established.
