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.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 1.8745 mL 9.3726 mL 18.7452 mL
5 mM 0.3749 mL 1.8745 mL 3.7490 mL
10 mM 0.1875 mL 0.9373 mL 1.8745 mL
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
