Target	IC50: 14.2 nM (FXIa); 27900 nM (PKal)[1]
In Vitro	FXIa-IN-8 (compound 35) (0-250 µg/mL) shows significant anticoagulant activity toward the intrinsic pathway without affecting the extrinsic pathway[1].
In Vivo	FXIa-IN-8 shows selectivity for FXIa and PKal with IC50s of 14.2, 27900 nM, respectively[1]. FXIa-IN-8 (6.5, 19.5 mg/kg; i.v.) shows antithrombotic activity in vivo[1]. FXIa-IN-8 (50, 100 mg/kg; i.v.) shows no acute toxicity[1]. FXIa-IN-8 (10 mg/kg; i.v.) shows moderate PK profiles[1].FXIa-IN-8 (19.5, 39 mg/kg) exhibits a much lower bleeding risk than heparin sodium at 300 IU/kg[1].

Animal Model: Male SD rats[1] Dosage: 10 mg/kg (300 IU/kg (2.7 mg/kg) heparin sodium were injected into the tail vein 10 min before surgery) Administration: I.v. Result: Showed moderate PK profiles with a half-life value (T1/2) of 1.26 h and a clearance (Cl) value of 553 mL/h/kg. Animal Model: C57BL/6J mice (FeCl3-induced carotid artery thrombus model)[1] Dosage: 6.5, 19.5 mg/kg Administration: I.v. Result: Slightly prolonged the time of occlusion at 6.5 mg/kg, and showed excellent antithrombotic activity at 35 mg/kg. Animal Model: ICR mice[1] Dosage: 50, 100 mg/kg Administration: I.v. Result: Showed no obvious toxic reaction to different tissues of mice. Animal Model: C57BL/6J mice[1] Dosage: 19.5, 39, 20, 60, 100 mg/kg Administration: I.v. Result: Showed a low bleeding risk at 60 and 100 mg/kg.
