描述 | JR14a, a potent thiophene antagonist of the human complement C3a receptor, exhibits selectivity for the human C3a receptor over the C5a receptor and can mitigate C3aR-mediated inflammation [1]. |
体内研究 | JR14a (10 mg/kg; pO. 2 h prior) diminishes paw swelling by 65% compared to control 30 minutes after agonist injection in an acute rat paw model of inflammation and edema [1]. JR14a (1 mg/kg; i.v.) exhibits an elimination half-life of 191 minutes, a clearance of 4.4 mL/min/kg, and an AUC of 3795 ng h/mL in rats [1]. JR14a (10 mg/kg; pO.) in rats displays a Cmax of 88 ng/mL, Tmax of 300 minutes, and an AUC of 478 ng h/mL [1]. |
体外研究 | JR14a (0.1 nM-100 μM) blocks C3a-induced intracellular Ca2+ release in human monocyte-derived macrophages, exhibiting an IC50 of 10 nM [1]. JR14a (0.1 nM-100 μM) maintains metabolic stability after exposure to rat liver microsomes for 1 hour [1]. JR14a (0.1 nM-100 μM) hinders C3a-induced β-hexosaminidase secretion in human LAD2 mast cells, with an IC50 of 8 nM [1]. |

溶解方案 |
DMSO: 105 mg/mL(196.82 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
