Biological Activity
| ln Vitro | ZQ-16 has an EC50 value of 0.213 μM and causes dose-dependent calcium responses [1]. Moreover, ZQ-16 reduced forskolin-stimulated cAMP buildup in GPR84-expressing HEK293 cells in a dose-dependent manner, with an EC50 value of 0.134 μM [1]. In HEK293 cells expressing GPR84, ZQ-16 (10 μM; 5 min) also causes phosphorylation of ERK1/2 [1]. ZQ-16 causes β-arrestin2 recruitment, internalization, and desensitization of GPR84. With an EC50 value of 0.597 μM, ZQ-16 causes dose-dependent recruitment of β-Arrestin2 to GPR84 in HEK293 cells expressing both proteins [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO: 25 mg/mL (109.50 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (10.95 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 (10.95 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 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (10.95 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
