JR14a

产品介绍 JR14a 是一种有效的人补体 C3a 受体噻吩拮抗剂。JR14a 对人 C3a 受体的选择性高于 C5a 受体。JR14a 可以抑制 C3aR 介导的炎症。
生物活性

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.

体外研究

JR14a (0.1 nM-100 μM) inhibits C3a-induced intracellular Ca2+ release in human monocyte-derived macrophages, with an IC50 of 10 nM.
JR14a (0.1 nM-100 μM) is metabolically stable to exposure over 1 h to rat liver microsomes.
JR14a (0.1 nM-100 μM) inhibits C3a-induced β-hexosaminidase secretion in human LAD2 mast cells, with an IC50 of 8 nM.

体内研究

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.
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.
JR14a (10 mg/kg; p.o.) exhibits Cmax (88 ng/mL), Tmax (300 min) and AUC (478 ng•h/mL) in rats.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Wister rats (8 weeks, 250-300 g) were injected with BR103
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)
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 ng•h/mL.
P.o.: Cmax=88 ng/mL, Tmax=300 min, AUC=478 ng•h/mL.
