Biological Activity
|
Human FP Receptor 1 nM (Ki) |
Rat FP Receptor 26 nM (Ki) |
Ebopiprant (OBE022) and OBE002 are assayed for FP binding affinity by competitive binding analysis with 3H-PGF2α using HEK293 cells stably transfected with the FP receptor. Binding affinities (Ki) of OBE022 for the human and rat FP receptor are 1 nM and 26 nM respectively. For OBE002, Kis are 6 nM for the human and 313 nM for the rat FP receptor. The binding of both OBE022 and OBE002 is reversible and competitive since increasing concentrations of either compound causes successive decreases in the slope of the binding curves, consistent with an increase in equilibrium dissociation constant (KD) without a reduction in receptor density[1].

Solvent & Solubility
DMSO : 250 mg/mL (416.85 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (3.47 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.08 mg/mL (3.47 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

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.
Protocol
Mice[1]
Primigravid CD1 mice, on day 17 of pregnancy (about 85% gestation) at the beginning of the experiments, are used. Approximately 3 hours before induction of preterm labor (Day 1 (D1) at 10h00), the pregnant mice at gestational day 17, are placed in individual cages with food and water ad libitum. Pregnant mice receive on D1 (at day time: 13h00) a single subcutaneous (s.c.) injection of RU486 at a dose of 2.5 mg/kg in a final volume of 10 mL/kg of sesame oil. OBE022 (10, 30 and 100 mg/kg) or nifedipine (5 mg/kg) are administered orally (p.o.) at a volume of 5 mL/kg once on D1 (18h00), twice on D2 (8h00 and 18h00) and once on D3 (8h00) for a total of 4 administrations. For combination treatment, mice receive OBE022 plus nifedipine using the same experimental design as single treatment[1].
