Uses
JR14a is a potent thiophene antagonist of human complement C3a receptor. JR14a shows selectivity for the human C3a receptor over C5a receptor. JR14a can suppress C3aR-mediated inflammation[1].
Biological Activity
JR14a is a potent thiophene antagonist of human complement C3a receptor. JR14a shows selectivity for the human C3a receptor over C5a receptor. JR14a can suppress C3aR-mediated inflammation[1]. JR14a (0.1 nM-100 μM) inhibits C3a-induced intracellular Ca2+ release in human monocyte-derived macrophages, with an IC50 of 10 nM[1].JR14a (0.1 nM-100 μM) is metabolically stable to exposure over 1 h to rat liver microsomes[1].JR14a (0.1 nM-100 μM) inhibits C3a-induced β-hexosaminidase secretion in human LAD2 mast cells, with an IC50 of 8 nM[1]. JR14a (10 mg/kg; p.o. 2 h prior) reduces paw swelling by 65% over control at 30 min after agonist injection in acute rat paw model of inflammation and edema[1].JR14a (1 mg/kg; i.v.) exhibits elimination half-life (191 min), clearance (4.4 mL/min/kg) and AUC (3795 ngh/mL) in rats[1].JR14a (10 mg/kg; p.o.) exhibits Cmax (88 ng/mL), Tmax (300 min) and AUC (478 ngh/mL) in rats[1].
in vivo
JR14a (10 mg/kg; p.o. 2 h prior) reduces paw swelling by 65% over control at 30 min after agonist injection in acute rat paw model of inflammation and edema[1].
JR14a (1 mg/kg; i.v.) exhibits elimination half-life (191 min), clearance (4.4 mL/min/kg) and AUC (3795 ng h/mL) in rats[1].
JR14a (10 mg/kg; p.o.) exhibits Cmax (88 ng/mL), Tmax (300 min) and AUC (478 ng h/mL) in rats[1].
| Animal Model: | Male Wister rats (8 weeks, 250-300 g) were injected with BR103[1] |
| Dosage: | 10 mg/kg |
| Administration: | P.o. 2 h prior to agonist challenge |
| Result: | Inhibited C3aR-mediated inflammation. |
| Animal Model: | Male Wister rats (8 weeks, 250-300 g)[1] |
| Dosage: | 1 mg/kg for i.v.; 10 mg/kg for oral (Pharmacokinetic Analysis) |
| Administration: | Intravenous administration and oral administration |
| Result: | I.v.: t1/2=191 min, clearance=4.4 mL/min/kg, AUC=3795 ngh/mL. P.o.: Cmax=88 ng/mL, Tmax=300 min, AUC=478 ngh/mL. |
