实验参考方法

Cell experiment:

Platelet aggregation is measured in hirudin-treated rabbit platelet-rich plasma (PRP) with a platelet aggregometer. PRP is mixed with 2.5 μL of vehicle or BMS-654457 at 1 and 10 μM and incubated for 2 min at 37°C. Peak platelet aggregation is determined after the addition of 2.5 μL of the agonist (ADP at 10 μM, arachidonic acid at 250 μM and collagen at 10 μg/mL, final concentration)[1].

Animal experiment:

Rabbits[1][1]BMS-654457 or vehicle (10 % N-N-dimethylacetamide:90 % of 5 % dextrose) is administered as a bolus plus sustaining IV infusion begun 30 min prior to each protocol. Treatment groups include BMS-654457 (mg/kg+mg/kg/h) at 0.011+0.008, 0.037+0.027, 0.11+0.08, 0.37+0.27 and 1.1 +0.8 or vehicle (n=6 per group). The plasma concentration that increased iCBF to EC50 was estimated for BMS654457[1].

产品描述

BMS-654457 is a small-molecule, reversible inhibitor of factor XIa (FXIa), binding with human and rabbit FXIa with Kis of 0.2 and 0.42 nM, respectively.

BMS-654457 shows comparable in vitro potency against FXIa in humans (Ki=0.2 nM) and in rabbits (Ki =0.42 nM), and was over 500-fold selective against coagulation-related proteases (thrombin, FXa and FVIIa) in these species[1].

BMS-654457 is effective in the prevention of arterial thrombosis in rabbits with limited effects on bleeding time. BMS-654457 is a promising antithrombotic therapy with a wide therapeutic window[1].

Research Update

In vitro, antithrombotic and bleeding time studies of BMS-654457, a small-molecule, reversible and direct inhibitor of factor XIa

J Thromb Thrombolysis 2015 Nov;40(4):416-23.PMID:26249722DOI:10.1007/s11239-015-1258-7

BMS-654457 ((+) 3'-(6-carbamimidoyl-4-methyl-4-phenyl-1,2,3,4-tetrahydro-quinolin-2-yl)-4-carbamoyl-5'-(3-methyl-butyrylamino)-biphenyl-2-carboxylic acid) is a small-molecule factor XIa (FXIa) inhibitor. We evaluated the in vitro properties of BMS-654457 and its in vivo activities in rabbit models of electrolytic-induced carotid arterial thrombosis and cuticle bleeding time (BT). Kinetic studies conducted in vitro with a chromogenic substrate demonstrated that BMS-654457 is a reversible and competitive inhibitor for FXIa. BMS-654457 increased activated partial thromboplastin time (aPTT) without changing prothrombin time. It was equipotent in prolonging the plasma aPTT in human and rabbit, and less potent in rat and dog. It did not alter platelet aggregation to ADP, arachidonic acid and collagen. In vivo, BMS-654457 or vehicle was given IV prior to initiation of thrombosis or cuticle transection. Preservation of integrated carotid blood flow over 90 min (iCBF, % control) was used as a marker of antithrombotic efficacy. BMS-654457 at 0.37 mg/kg + 0.27 mg/kg/h produced almost 90 % preservation of iCBF compared to its vehicle (87 ± 10 and 16 ± 3 %, respectively, n = 6 per group) and increased BT by 1.2 ± 0.04-fold (P < 0.05). At a higher dose (1.1 mg/kg + 0.8 mg/kg/h), BMS-654457 increased BT by 1.33 ± 0.08-fold. This compares favorably to equivalent antithrombotic doses of reference anticoagulants (warfarin and dabigatran) and antiplatelet agents (clopidogrel and prasugrel) which produced four- to six-fold BT increases in the same model. In summary, BMS-654457 was effective in the prevention of arterial thrombosis in rabbits with limited effects on BT. This study supports inhibition of FXIa, with a small-molecule, reversible and direct inhibitor as a promising antithrombotic therapy with a wide therapeutic window.
