GLPG1205 is novel, specific, orally bioactive and negative allosteric GPR84 antagonist with a favorable PK/PD profiles. GLPG1205 has anti-inflammatory activity and is used for the treatment of pulmonary fibrosis. GLPG1205 reduced disease activity index score and neutrophil infiltration in a mouse dextran sodium sulfate-induced chronic inflammatory bowel disease model, with efficacy similar to positive-control compound sulfasalazine. The drug discovery steps leading to GLPG1205 identification, currently under phase II clinical investigation, are described herein.
| ln Vitro |
Neutrophils that are stimulated by ZQ16 to produce [Ca2+]i respond entirely to GLPG1205 (0.5 μM) [1]. The ROS response caused by GPR84 agonist is totally blocked by GLPG1205 (1 μM) when applied for 5 minutes [1]. ZQ16-induced ROS can be successfully countered by GLPG1205, as demonstrated by its IC50 value of 15 nM in TNF-primed neutrophils[1].

| ln Vivo |
In a model of idiopathic pulmonary fibrosis, GLPG1250 (orally given; 30 mg/kg; twice daily) dramatically decreased Ashcroft scores commencing 7 days after challenge and continuing for 2 weeks [3]. ? In mice, GLPG1250 (given orally at a dose of 30 mg/kg once day) dramatically decreased lung deposition beginning eighteen weeks after radiation. Moreover, GLPG1250 prevents lung bronchial epithelial cells and parenchymal macrophages from increasing MnSOD in a radiation model [3]. ? GLPG1205 dose-dependently decreased colonic MPO levels, neutrophil influx, disease activity, and histopathological activity in a mouse model of IBD [4].

| Solubility (In Vivo) |
Solubility in Formulation 1: 6.25 mg/mL (16.52 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 62.5 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: ≥ 6.25 mg/mL (16.52 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 62.5 mg/mL clear DMSO stock solution to 900 μL corn oil and mix evenly. View More
Solubility in Formulation 3: 5 mg/mL (13.21 mM) in 0.5% CMC-Na/saline water (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
