Application

CP-105,696 has been used as a leukotriene B4 receptor (LTB4R) antagonist to study the influence of the LTB4 pathway in the pathogenesis of acute itch flares in irritant calcipotriol (MC903)+ model allergen ovalbumin (OVA) sensitized murine model of atopic dermatitis (AD)-like disease.

Actions biochimiques/physiologiques

CP-105,696 is an orally active, potent and selective leukotriene B4 receptor (LTB4R) antagonist (IC50 against [3H]LTB4 = 5.6 nM for binding human neutrophils; IC50 = 9.7 nM & 30.3 nM, respectively using guinea pig spleen or mouse membranes) that targets LTB4R high- and low-affinity binding sites in a LTB4 non-competitive and competitive manner, respectively. CP-105,696 inhibits 5 nM LTB4-induced human neutrophils chemotaxis and CDllb upregualtion (IC50 = 5.2 nM and 430 nM, respectively) without inhibiting cyclooxygenase activity or affecting chemotaxis induced by C5a, PAF, IL-8. Oral administration is efficacious against intradermal LTB4 (100 ng/mouse), but not IL-1, injection-induced neutrophil accumulation in mice and guinea pigs (ED50 = 4.2 and 0.26 mgkg, respectively). CP-105,696 in vivo efficacy is also demonstrated in other animal models, including collagen-induced arthritis (CIA; 0.3-10 mg/kg in mice), allergic encephalomyelitis (ED50= 8.6 mg/kg; mice), and asthma (10-30 mg/kg; primate).

Leukotriene B4 (LTB4) is a product of the 5-lipoxygenase pathway of arachidonic acid metabolism. LTB4 is a potent chemotactic factor for neutrophils and has been postulated to play an important role in a variety of pathological conditions including rheumatoid arthritis

To test the hypothesis that leukotriene (LT) B4 antagonists may be clinically useful in the treatment of asthma, CP-105,696 was evaluated in vitro, using chemotaxis and flow cytometry assays, and in vivo, using a primate asthma model. CP-105,696 inhibited LTB4-mediated

Itch is an evolutionarily conserved sensation that facilitates expulsion of pathogens and noxious stimuli from the skin. However, in organ failure, cancer, and chronic inflammatory disorders such as atopic dermatitis (AD), itch becomes chronic, intractable, and debilitating. In addition to
