PAR1 .29 μM (IC50) |
FR171113 shows antiplatelet effect on the aggregation of guinea pig platelets induced by PAR1 agonist peptide and thrombin in vitro with IC50s of 1.5 and 0.35 μM, respectively[2].
FR171113 (0.032-1 μM) dose-dependently inhibits platelet aggregation induced by both thrombin and TRAP-6[1].
FR171113 significantly prevents the plasma-elicited up-regulation of RAGE, MCP-1 and ICAM-1 mRNA levels in HUVECs[2].
FR171113 (1 μM; pretreatment for 30 minutes) inhibits thrombin- and SFLLRN (human PAR1 agonist peptide)-induced ERK activation, but not factor Xa- or SLIGKV (PAR2 agonist peptide)-induced ERK activation, indicating that activation of ERK by factor Xa is specifically mediated by PAR2 in mesangial cells[3].

Cell Line:Human washed platelets
-
Concentration:0.001, 0.01, 0.1, 1, 10, 100 μM
-
Incubation Time:
-
Result: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.
-
Cell Line:human umbilical vein endothelial cells (HUVECs)
-
Concentration:1 μM
-
Incubation Time:4 hours
-
Result:3% citrated human plasma-evoked ROS generation, RAGE, MCP-1 and ICAM-1 gene induction was significantly blocked.
-
Cell Line:Mesangial cells
-
Concentration:1 μM
-
Incubation Time:Pretreatment for 30 minutes
-
Result:Pretreatment inhibited thrombin (10 nM; for 5 minutes)- and SFLLRN(100 μM for 5 minutes)-induced ERK activation.

-
Animal Model:Male Hartley guinea pigs (650–950 g) were anesthetized with urethane (1.25 g/kg, i.p.)[4]
-
Dosage:0.32, 1.0, and 3.2 mg/kg
-
Administration:Administered subcutaneously (s.c.)
-
Result: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.
