Notes: NDT 9513727 is a competitive antagonist of the C5a receptor (C5aR; IC50 = 11.6 nM for human recombinant receptors) that has inverse agonist activity in a GTPγ[35S] assay.{35197,43605} It is selective for human recombinant over rat and mouse recombinant C5aRs (IC50 = >10 µM for both) but does have activity at macaque and gerbil receptors (IC50s = 7.3 and 6.4 nM, respectively). NDT 9513727 inhibits degranulation in U937 cells stimulated with C5a (IC50 = 7.1 nM). It also prevents neutropenia induced by human recombinant C5a in gerbils (ED50 = 2.2 mg/kg) and in cynomolgus macaques when administered at doses of 5 and 25 mg/kg.{43605}
