Compound Overview
Prasugrel hydrochloride, also known as PCR 4099 hydrochloride, is a thienopyridine prodrug that inhibits platelet function. It is an orally active P2Y12 receptor antagonist that inhibits ADP-induced platelet aggregation[1]. It is supplied as a light yellow to yellow solid (C20H21ClFNO3S, MW 409.90) at 98.49% purity.

Safety
For Research Use Only. Not for use in diagnostic or therapeutic procedures, and not for human or veterinary use. Handle in accordance with the Safety Data Sheet and your institution's chemical hygiene plan.
In Vitro
| Solvent | Solubility | Notes |
|---|---|---|
| DMSO | 41.67 mg/mL (101.66 mM) | requires sonication; use freshly opened DMSO (absorbed moisture lowers solubility) |
Aliquot the stock solution and store it at -80°C (up to 6 months) or -20°C (up to 1 month); sealed storage, away from moisture and light; avoid repeated freeze-thaw cycles.
In Vivo
Choose the formulation that suits the animal model and route of administration; percentages are volume ratios of the final working solution. Start from a clear DMSO stock (see In Vitro above), add the co-solvents one at a time in the order listed, mixing after each addition, and prepare the working solution fresh on the day of dosing. If precipitation or phase separation occurs, gentle warming or sonication can help.
Protocol 1
| Composition | 10% DMSO + 40% PEG300 + 5% Tween-80 + 45% saline |
|---|---|
| Result | ≥ 2.08 mg/mL (5.07 mM); clear solution |
| How to prepare | Gives a clear solution at ≥ 2.08 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 400 μL PEG300; then 50 μL Tween-80; then 450 μL saline to bring the volume to 1 mL. Saline: dissolve 0.9 g sodium chloride in ddH2O and make up to 100 mL. |
Protocol 2
| Composition | 10% DMSO + 90% (20% SBE-β-CD in saline) |
|---|---|
| Result | ≥ 2.08 mg/mL (5.07 mM); clear solution |
| How to prepare | Gives a clear solution at ≥ 2.08 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 900 μL 20% SBE-β-CD in saline. 20% SBE-β-CD in saline: dissolve 2 g SBE-β-CD powder in 10 mL saline until clear (4°C, store up to one week). |
Protocol 3
| Composition | 10% DMSO + 90% Corn Oil |
|---|---|
| Result | ≥ 2.08 mg/mL (5.07 mM); clear solution |
| How to prepare | Gives a clear solution at ≥ 2.08 mg/mL (saturation not determined). Use with caution if continuous dosing will exceed two weeks. For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 900 μL corn oil. |

In Vivo
In rat platelets, the active metabolite of Prasugrel hydrochloride inhibits in vitro platelet aggregation triggered by ADP (10μM), with an IC50 value of 1.8 μM[2]. In vivo, Prasugrel hydrochloride acts faster than Clopidogrel and is significantly more potent. Prasugrel hydrochloride is an inactive prodrug, and metabolic processing in vivo is needed to produce the active antiplatelet metabolite. It is absorbed rapidly from the gut. After oral standard-loading doses of 60 mg, the active metabolite reaches maximum plasma levels within 1 h, and effective, maximum inhibition of platelet aggregation occurs at 1-2 h[1].
