Biological Activity
| ln Vitro | JR14a cells, whose IC50 ranges from 0.1 nM to 100 μM, have been shown to block C3a-induced internal Ca2+ release in human monocyte-derived macrophages[1]. An IC50 of 8 nM is observed in human LAD2 mast cells exposed to intravenous injection of JR14a (0.1 nM-100 μM) to inhibit C3a β-hexosaminidase [1]. |
| ln Vivo | JR14a (10 mg/kg; po 2 h before) induced 65% more paw swelling than controls 30 minutes after hemostatic injection in an acute state paw model of edema and edema [1]. JR14a (1 mg/kg; iv) exhibited elimination half-life (191 minutes), clearance (4.4 mL/min/kg), and AUC (3795 ng·h/mL) at shelf [1]. JR14a (10 mg/kg; po) exhibited Cmax (88 ng/mL), Tmax (300 min), and AUC (478 ng h/mL) at shelf [1]. |
| Animal Protocol |
Animal/Disease Models: Male Wister rats (8 weeks, 250-300 g) were injected with BR103[1]. Doses: 10 mg/kg Route of Administration: Oral 2 hrs (hrs (hours)) before agonist challenge Experimental Results: Inhibits C3aR-mediated inflammation. Animal/Disease Models: Male Wister rat (8 weeks, 250-300 g) [1] Doses: 1 mg/kg, intravenous (iv) (iv)injection; oral 10 mg/kg (pharmacokinetic/PK/PK analysis) Route of Administration: intravenous (iv) (iv)administration and oral administration Dosing Experimental Results: IV: t1/2=191 min, clearance=4.4 mL/min/kg, AUC=3795 ng·h/mL. Po: Cmax=88 ng/mL, Tmax=300 minutes, AUC=478 ng·h/mL. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~187.45 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.69 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.69 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 3: 2.5 mg/mL (4.69 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
