生物活性

製品説明 Lumiracoxib（COX-189）は、Kiが0.06 μMの新規選択的COX-2阻害剤です。また、Kiが3 μMでCOX1も阻害します。
in vitro Lumumiracoxib has an IC50 of 0.14 μm in COX-2-expressing dermal fibroblasts, but caused no inhibition of COX-1 at concentrations up to 30 μm (HEK 293 cells transfected with human COX-1). In a human whole blood assay, IC50 values for this compound are 0.13 μM for COX-2 and 67 μM for COX-1 (COX-1/COX-2 selectivity ratio 515).
in vivo Lumiracoxib is a highly selective COX-2 inhibitor with anti-inflammatory, analgesic and antipyretic activities comparable with diclofenac, the reference NSAID, but with much improved gastrointestinal safety. This compound is rapidly absorbed following oral administration in rats with peak plasma levels being reached between 0.5 and 1 h. Efficacy of this chemical in rat models of hyperalgesia, oedema, pyresis and arthritis is dose-dependent and similar to diclofenac. However, consistent with its low COX-1 inhibitory activity, it at a dose of 100 mg/kg orally causes no ulcers and is significantly less ulcerogenic than diclofenac.

プロトコル(参考用のみ)

キナーゼアッセイ Inhibition of purified COX-1 and COX-2
Purified enzyme preparations with control activities of 80 nmol of O2 consumption min−1 are pretreated with inhibitors at 37°C for various lengths of time (0–60 min). Arachidonic acid (20 μM) is then added, and O2 consumption measured using an oxygen electrode. Kinetic parameters are calculated.
動物実験 動物モデル Female Lewis rats
投薬量 0.2–2 mg/kg
投与方法 Oral gavage
