ln Vitro |
With IC50s of 1.5 and 0.35 μM, respectively, FR171113 exhibits an antiplatelet effect on the aggregation of guinea pig platelets induced by PAR1 agonist peptide and thrombin in vitro[2]. FR171113 (0.032-1 μM) inhibits platelet aggregation that is induced by TRAP-6 and thrombin in a dose-dependent manner[1]. In HUVECs, FR171113 dramatically inhibits the up-regulation of RAGE, MCP-1, and ICAM-1 mRNA levels that is induced by plasma[2]. FR171113 (1 μM; pretreatment for 30 minutes) inhibits ERK activation induced by thrombin and SFLLRN (human PAR1 agonist peptide), but not that induced by factor Xa or SLIGKV (PAR2 agonist peptide), suggesting that PAR2 in mesangial cells specifically mediates ERK activation by factor Xa[3].

ln Vivo |
In the carotid artery thrombosis model, FR171113 significantly prolongs the disease process at 1 mg/kg sc and suppresses occlusive thrombosis in a dose-dependent manner. In vivo, FR171113 exhibits antiplatelet and antithrombotic properties. A helpful tool for examining antithrombotic effects via PAR1 in vivo is FR171113[4].

Cell Viability Assay[1]
Cell Types: Human washed platelets Tested Concentrations: 0.001, 0.01, 0.1, 1, 10, 100 μM Incubation Duration: Experimental Results: The IC50 value for thrombin-induced platelet aggregation was 0.29 μM. The IC50 value for TRAP-6 -induced platelet aggregation was 0.15 μM. RT-PCR[2] Cell Types: human umbilical vein endothelial cells (HUVECs) Tested Concentrations: 1 μM Incubation Duration: 4 hrs (hours) Experimental Results: 3% citrated human plasma-evoked ROS generation, RAGE, MCP- 1 and ICAM-1 gene induction was Dramatically blocked. Western Blot Analysis[3] Cell Types: Mesangial cells Tested Concentrations: 1 μM Incubation Duration:Pretreatment for 30 minutes Experimental Results: Pretreatment inhibited thrombin (10 nM; for 5 minutes)- and SFLLRN( 100 μM for 5 minutes)-induced ERK activation. |
Animal Protocol |
Animal/Disease Models: Male Hartley guinea pigs (650–950 g) were anesthetized with urethane (1.25 g/kg, ip)[4]
Doses: 0.32, 1.0, and 3.2 mg/kg Route of Administration: Administered subcutaneously (sc) (sc) Experimental Results: Pretreatment with FR171113 prolonged this parameter in a dose-dependent manner. The time to thrombotic occlusion for 0.32, 1.0 and 3.2 mg/kg of FR171113 was 30.7±5.36, 44.7±8.41 and 92.6±9.79, respectively. |

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

*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.
