Activité biologique
IC50: 0.1 nM (complement 5a receptor )[1]
CCX168 displaces [125I]-C5a binding to C5aR on a human myeloid cell line (U937) with a potency (IC50) of 0.1 nM. CCX168 inhibits C5a-mediated chemotaxis of U937 cells with a potency (the concentration of CCX168 that produces a 2-fold right-shift in C5a activity) of 0.2 nM. CCX168 competitively and selectively blocked C5a-induced calcium mobilization in purified human neutrophils, with an IC50 value of 0.2 nM. CCX168 inhibited C5a-induced release of reactive-oxygen species from isolated neutrophils, and is able to completely block respiratory burst in these neutrophils[1].

Avacopan purchased from MedChemExpress. Usage Cited in: bioRxiv. 2025 Oct 29.
Inhibition of the C5a-induced response by the specific C5aR1 antagonist Avacopan. TNF-primed neutrophils were incubated without (solid line) or with Avacopan (50 nM, dashed line) for 5 min before addition of C5a (2 nM; added at the time point marked with an arrow) and determination of the NADPH oxidase activity. Inset: The inhibitory effect of Avacopan on the neutrophil NADPH oxidase activity expressed as peak values (Mcpm) of O2-production induced by C5a in absence and presence of the antagonist, respectively (mean ± SEM, n = 6).

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
