Description
W-54011 is a potent and orally active non-peptide C5a receptor antagonist. W-54011 inhibits the binding of 125I-labeled C5a to human neutrophils with a Ki value of 2.2 nM. W-54011 also inhibits C5a-induced intracellular Ca2+ mobilization, chemotaxis, and generation of ROS in human neutrophils with IC50s of 3.1 nM, 2.7 nM, and 1.6 nM, respectively.

How to use
In Vitro:
In C5a-induced intracellular Ca2+ mobilization assay with human neutrophils, W-54011 does not show agonistic activity at up to 10 μM and shifts rightward the concentration-response curves to C5a without depressing the maximal responses, indicating that W-54011 is a full antagonist. At concentrations up to 10 μM, W-54011 does not affect Ca2+ mobilization stimulated with sub-maximally effective concentrations of fMLP (1 nM), plateletactivating factor (0.3 nM), and IL-8 (0.1 nM). This result demonstrates that W-54011 is highly specific for C5a receptor.
In Vivo:
W-54011 (3-30 mg/kg; oral administration; for 4 hours; male mongolian gerbils) treatment inhibited C5a-induced neutropenia in a dose-dependent manner in gerbils. The species selectivity of W-54011 is examined in rhC5a-induced intracellular Ca2+ mobilization of neutrophils in various species. The W-54011 is able to inhibit the response in cynomolgus monkeys and gerbils with IC50 values of 1.7 nM and 3.2 nM, respectively, but not in mice, rats, guinea pigs, rabbits, and dogs.
