- human activated blood coagulation factor X manufactured by Enzyme Research
- Solution 501 was added, the absorbance was measured, and the initial reaction rate was determined.
- a control was prepared by adding 10-1 of Tris-HCl buffer adjusted to pH 8.4 instead of the solution of the evaluation compound. The absorbance was measured using MICROPLATE READER Model 3550-UV (BIO RAD) at a wavelength of 405 nm at intervals of 15 seconds for 16 minutes. 50% inhibition of thrombin activity (initial velocity) when no test compound is added (abbreviated as PIC50) was used as an index of thrombin inhibitory activity.
- the thrombin inhibitory activity of representative compounds is shown in Table 1 below.
- Anticoagulant activity was determined using the prothrombin time (PT) assay.
- PT measurement was performed as shown below. That is, blood was collected from a healthy person, and 1/10 volume of a 3.8% aqueous solution of trisodium citrate was added thereto, and plasma was separated by centrifugation. Plasma (4) was added with 5 ⁇ 1 of DMS0 solution containing the compound to be evaluated, and incubated at room temperature for 2 minutes. After installing the test tube containing the plasma solution on a Sysmex CA-3000 fully automatic blood coagulation analyzer (Toa Medical Electronics), incubate at 37 ° C for 3 minutes, and load Sysmex PT II (Toa Medical Electronics, Esagi Brain).
- Sysmex CA-3000 fully automatic blood coagulation analyzer
- Tissue thromboplastin, 13.2 ⁇ (chloridium lucidum) 100 ⁇ 1 was added. ⁇ was automatically measured by the same apparatus.
- a control was prepared by adding DMS05 ⁇ 1 instead of the test compound solution, and the negative logarithm of the test compound concentration that prolonged the control PT by a factor of 2 (abbreviated as pPT2) was determined. The index was used.
- the structural formulas of the compounds of the present invention described in the examples are shown below.
- an anticoagulant containing the compound of the present invention or a salt thereof as an active ingredient exhibits an excellent anticoagulant effect based on an activated blood coagulation factor X inhibitory effect. Therefore, the compounds of the present invention are useful for diseases in cerebrovascular disorders such as cerebral infarction, stroke, cerebral thrombosis, cerebral embolism, transient ischemic attack (TIA), subarachnoid hemorrhage (vascular spasm), acute and chronic myocardial infarction, Diseases in ischemic heart disease such as unstable angina, coronary artery thrombosis, diseases in pulmonary vascular disorders such as pulmonary infarction, pulmonary embolism, peripheral arterial occlusion, deep vein thrombosis, generalized intravascular coagulation, In addition, thrombus formation after vascular angioplasty and valve replacement, reocclusion and restenosis after coronary artery bypass surgery, percutaneous transluminal coronary angioplasty (PTCA) or percutaneous transluminal coronary ang
