Biochem/physiol Actions

Lumiracoxib (COX189) is an orally active, potent and selective cyclooxygenase-2 inhibitor (Ki = 60 nM/COX-2 vs. 3.2 μM/COX-1) that inhibits COX-2-mediated PGE2 production in human whole blood (IC50 = 130 nM; stimulation = 50 μM A23187), but not COX-1-dependent TxB2 production (IC50 = 67 μM; stimulation = 10 μg/mL LPS). Lumiracoxib shows in vivo anti-inflammatory efficacy against carrageenan-induced paw oedema (ED30 = 0.35 mg/kg p.o.), CFA-induced hyperalgesia (ED30 = 5.1 mg/kg p.o.), as well as adjuvant-induced arthritis (ED50 = 3 mg/kg/day p.o.) in rats in vivo.

Pain, 107(1-2), 33-40 (2004-01-13)
Chronic pain resulting from metastatic bone cancer remains poorly understood and resistant to treatment. Here we have examined the effect of the novel COX-2 enzyme inhibitor lumiracoxib in a model of bone cancer pain in the rat. Lumiracoxib was administered

Lumiracoxib is a selective cyclooxygenase-2 inhibitor, which has been reported to cause rare but severe liver injury. Considering that lumiracoxib has a carboxylic group in the molecule, glucuronidation to form acylglucuronide would be one of the possible mechanisms of lumiracoxib-induced

Toxicology and applied pharmacology, 369, 39-48 (2019-02-16)
The occurrence of drug hypersensitivity reactions (DHRs) following administration of low molecular weight (LMW) drugs is an important health concern. However, in vivo animal models which could be used as tools for the prediction of DHRs are lacking. As a

Neurobiology of stress, 11, 100190-100190 (2019-08-31)
Chronic stress increases the probability of receiving an anxiety, depression, or chronic illness diagnosis. Pharmacological interventions that reduce the behavioral and physiological effects of chronic stress in animal models may represent novel approaches for the treatment of stress-related psychiatric disorders.

1. This manuscript presents the preclinical profile of lumiracoxib, a novel cyclooxygenase-2 (COX-2) selective inhibitor. 2. Lumiracoxib inhibited purified COX-1 and COX-2 with K(i) values of 3 and 0.06 microM, respectively. In cellular assays, lumiracoxib had an IC(50) of 0.14
