Ozagrel hydrochloride
Based on 1 publication(s) in Google Scholar
Ozagrel hydrochloride (OKY-046 hydrochloride) is a high selective and orally active thromboxane A2 (TXA2) synthase inhibitor with an IC50 of 11 nM. Ozagrel hydrochloride exerts anti-platelet aggregation, vasodilation and anti-inflammatory effects by inhibiting the production of TXA2 and increasing the production of prostacyclin (PGI2). Ozagrel hydrochloride can be used for the study of ischemic stroke, asthma and thromboembolic diseases.

Ozagrel hydrochloride significantly inhibits platelet aggregation induced by Arachidonic acid (HY-109590) with an IC50 of 53.12 μM[1].
Ozagrel hydrochloride (100 μM) exhibits the inhibitory rate on plasma TXB2 of 99.6% but has no inhibitory effect on PGH2[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Ozagrel (80 mg/kg, i,v., single dose) hydrochloride attenuates lung injury and decreases monocyte chemoattractant protein-1 and interleukin-8 mRNA expression in Oleic acid (OA) (HY-N1446)-induced lung injury in guinea pigs[4].

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 (7.86 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 (7.86 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 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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: PBS
