Description

GPR84 antagonist 8 is a selective GPR84 antagonist.

IC₅₀ & Target

GPR84^[1]

In Vitro

GPR84 is a member of the metabolic G protein-coupled receptor family, and its expression has been described predominantly in immune cells. To test the hypothesis that blocking the activation of GPR84 can be a potential anti-inflammatory strategy in different inflammatory diseases, GPR84 antagonist 8 is used. The potency and specificity of GPR84 antagonist 8 is assessed tusing GPR84-CHO cells in the cAMP assay. GPR84 antagonist 8 effectively inhibits the action of 6-OAU in decreasing cAMP production in GPR84-CHO cells. To test GPR84 antagonist 8’s inhibition of the pro-inflammatory effects of GPR84 activation in macrophages, LPS pre-treated BMDMs are incubated with 10 µM GPR84 antagonist 8 for 30 min before adding 1 µM 6-OAU. Protein analysis by Western Blot shows that the GPR84 antagonist 8 partially blocks the phosphorylation of AKT and ERK induced by 6-OAU^[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.54 mg/mL (1.28 mM); Clear solution

This protocol yields a clear solution of ≥ 0.54 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.4 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.54 mg/mL (1.28 mM); Clear solution

This protocol yields a clear solution of ≥ 0.54 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.4 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 0.54 mg/mL (1.28 mM); Clear solution

This protocol yields a clear solution of ≥ 0.54 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.4 mg/mL) to 900 μL Corn oil, and mix evenly.

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Cell Assay
^[1]

Bone marrow-derived macrophages treated with either vehicle (0.3% DMSO) or 1 µM 6-OAU for 1 h are incubated with unopsonised pHrodo E. coli bioparticles at 0.1 mg/mL in a 96-well flat clear bottom plate. For the inhibition studies with GPR84 antagonist 8, cells are pretreated with 10 µM GPR84 antagonist 8 for 30 min before addition of either vehicle or 6-OAU. The plate is then placed into the IncuCyte Zoom platform which is housed inside a humidified incubator at 37°C, 5% CO₂. Two to four images per well from three technical replicates are taken every 15 min for 4 h^[1].
