Zingerone Alleviates Morphine Tolerance and Dependence in Mice by Reducing Oxidative Stress-Mediated NLRP3 Inflammasome Activation.

Morphine (MPH) is widely used for pain management; however, long-term MPH therapy results in antinociceptive tolerance and physical dependence, limiting its clinical use. Zingerone (ZIN) is a natural phenolic compound with neuroprotective effects. We investigated the effects of single and repeated doses of ZIN on MPH-induced tolerance, dependence, and underlying biochemical mechanisms.

PMSF Attenuates Morphine Antinociceptive Tolerance and Dependence in Mice: Its Association with the Oxidative Stress Suppression.

Opioids use has been limited due to tolerance and dependence as major unwanted effects. Previous evidence has shown that targeting endocannabinoid signaling can prevent the development of opioid tolerance and dependence. This study was designed to evaluate the effect of phenylmethylsulfonyl fluoride (PMSF), an inhibitor of fatty acid amide hydrolase (FAAH), on morphine antinociceptive tolerance and physical dependence in mice.

Epicatechin protective effects on bleomycin-induced pulmonary oxidative stress and fibrosis in mice.

Lung fibrosis is a chronic and intermittent pulmonary disease, caused by damage to the lung parenchyma due to inflammation and fibrosis. Epicatechin (Epi) as a flavonoid has antioxidant and anti-inflammatory properties. This study was conducted to evaluate the effect of Epi on oxidative stress, inflammation and pulmonary fibrosis induced by bleomycin (BLM) in mice.

Gastroprotective Effect of Zingerone on Ethanol-Induced Gastric Ulcers in Rats.

Zingerone is an ingredient of ginger () with different pharmacological activities. Several studies have investigated the effect of zingerone on various gastrointestinal diseases, including irritable bowel syndrome and diarrhea. This study is aimed to evaluate the effect of zingerone on ethanol-induced gastric ulcers in rats.
