Cat.No. 3333 - NDT 9513727 | C36H35N3O4 | CAS No. 439571-48-9
Description: Potent, selective human C5a receptor antagonist
Chemical Name: N,N-Bis(1,3-benzodioxol-5-ylmethyl)-1-butyl-2,4-diphenyl-1H-Imidazole-5-methanamine
Purity: ≥98% (HPLC)

Biological Activity

Potent C5a receptor (C5aR) competitive antagonist (IC50 = 11.6 nM); selective for human C5aR (IC50 values for rat and mouse C5aR are > 10 μM). Exhibits inverse agonist pharmacokinetics. Blocks degranulation response in C5a-stimulated U937 cells (IC50 = 7.1 nM). Exhibits selectivity for primate and gerbil receptor over other species. Orally bioavailable.
