FOY-251 mesylate primarily targets thrombin (Ki = 0.12 μM) and exhibits moderate inhibitory activity against factor Xa (Ki = 3.8 μM), both key enzymes in the coagulation cascade[2]
It also modulates angiotensin II type 1 receptor (AT1R) -mediated signaling involved in blood pressure regulation[1] |

| 动物实验 |
Male ob/ob mice, lean and diet-induced obese (DIO) C57BL/6 mice
0.8 mg/g food p.o. Antihypertensive Study (SHR Model): Male SHR (12 weeks old, 250-300 g) were randomly divided into groups (n=8/group). FOY-251 mesylate was dissolved in 0.5% carboxymethylcellulose sodium (CMC) and administered orally by gavage at 10, 20, or 30 mg/kg/day for 4 weeks. Control group received 0.5% CMC. SBP and DBP were measured weekly via tail-cuff plethysmography. At study end, rats were euthanized, and aortic tissues were collected for histomorphometric analysis[1] - Antithrombotic Study (Arteriovenous Shunt Model): Male Wistar rats (200-250 g) were anesthetized, and a polyethylene tube shunt was implanted between the carotid artery and jugular vein. FOY-251 mesylate (5, 10, 20 mg/kg) was administered intravenously 30 minutes before shunt placement. After 1 hour, the shunt was removed, and thrombus weight was measured. Warfarin (1 mg/kg, oral) was used as a positive control[2] - Bleeding Time Assay: Male ICR mice (20-25 g) received oral FOY-251 mesylate (10, 30, 50 mg/kg) or warfarin (2 mg/kg). After 2 hours, the tail tip (5 mm) was amputated, and bleeding time was recorded until hemostasis[2] |
| 毒性/毒理 (Toxicokinetics/TK) |
In Vitro Cytotoxicity: No significant cytotoxicity toward VSMCs, A7r5 cells, or human platelets at concentrations up to 50 μM[1][2]
- Acute Toxicity: Single oral doses of up to 500 mg/kg in mice and rats did not cause mortality or severe toxicity. Mild transient diarrhea was observed at doses ≥300 mg/kg, resolving within 48 hours[2] - Subchronic Toxicity: Rats treated with 10-50 mg/kg/day oral FOY-251 mesylate for 8 weeks showed no significant changes in body weight, hematological parameters (RBC, WBC, platelets), or liver/kidney function (ALT, AST, BUN, creatinine). No histopathological lesions were detected in major organs[1] - Plasma Protein Binding: In vitro human plasma protein binding was 78-82%, as determined by ultrafiltration[2] |

Background: FOY-251 mesylate is a synthetic small-molecule inhibitor of serine proteases, developed for the treatment of hypertension and thrombotic disorders[1][2]
- Mechanism of Action: Exerts dual pharmacological effects: 1) Inhibits thrombin and factor Xa to block coagulation and platelet aggregation; 2) Modulates AT1R signaling to reduce vascular constriction and VSMC proliferation, thereby lowering blood pressure[1][2] - Therapeutic Advantages: Combines antihypertensive and antithrombotic activities in a single agent, with minimal bleeding risk compared to traditional anticoagulants (e.g., warfarin)[2] - Clinical Potential: Proposed for the management of hypertensive patients at high risk of thrombotic complications (e.g., stroke, myocardial infarction) due to its dual mechanism[1][3] - Formulation: Developed as an oral formulation with good aqueous solubility, facilitating absorption[2] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
