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. 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. | [Uses]
NDT 9513727 is a selective, and potent inverse agonist of the human C5aR. NDT 9513727 has been shown to effectively inhibit C5a-induced neutropenia in gerbil and cynomolgus macaque in vivo. These results suggest that NDT 9513727 is a promising candidate for the treatment of human inflammatory diseases. | [in vivo]
NDT 9513727 (3-30 mg/kg; p.o.) exhibits a dose-dependent inhibition of hC5a-induced neutropenia[1].
?
NDT 9513727 exhibits moderate oral bioavailability (rat 73%, monkey 26%) and Cmax (rat 5.98 μM, monkey 830 nM) following oral administration (rat 50, monkey 25.2 mg/kg)[1].
?
NDT 9513727 exhibits moderate plasma elimination half-lives (rat 4.8, monkey 7.9 h) due to low plasma clearance (1.4 L/h/kg and 3.8 L/h/kg respectively) following oral administration (rat 50, monkey 25.2 mg/kg)[1].
