Benzodiazepine derivatives

The present invention relates to new benzodiazepine derivatives which can be orally administrated to exhibit a strong anticoagulant effect by reversibly inhibiting activated blood-coagulation factor X; anticoagulants containing them as active ingredients; and agents for preventing or treating diseases caused by thrombi or emboli. These diseases include, for example, cerebrovascular disorders such as cerebral infarction, cerebral stroke, cerebral thrombosis, cerebral embolism, transient ischemic attack (TIA) and subarachnoidal hemorrhage (vasospasm); ischemic heart diseases such as acute and chronic myocardial infarction, unstable angina and coronary thrombolysis; pulmonary vascular disorders such as pulmonary infarction and pulmonary embolism; peripheral arterial occlusive disease; deep vein thrombosis; disseminated intravascular coagulation; thrombus formation after an artificial blood vessel-forming operation or an artificial valve substitution; reocclusion and restenosis after a coronary artery bypass grafting; reocclusion and restenosis after a reconstructive operation for the blood circulation such as percutaneous transluminal coronary angioplasty (PTCA) or percutaneous transluminal coronary recanalization (PTCR); and thrombus formation in the course of the extracorporeal circulation.

As the habit of life is being westernized and people of advanced ages are increasing in Japan, thrombotic and embolismic patients such as those suffering from myocardial infarction, cerebral thrombosis and peripheral thrombosis are increasing in number year by year, and the treatment of patients with these diseases is becoming more and more important in the society. Anticoagulation treatment is included in the internal treatments for the remedy and prevention of thrombosis, like fibrinolytic therapy and antiplatelet therapy.

Thrombin inhibitors were developed as thrombus-formation inhibitors in the prior art. However, it has been known that since thrombin not only controls the activation of fibrinogen to form fibrin, which is the last step of the coagulation reaction, but also deeply relates to the activation and aggregation of blood platelets, the inhibition of the action of thrombin causes a danger of causing hemorrhage. In addition, when thrombin inhibitors are orally administered, the bioavailability thereof is low. At present, no thrombin inhibitors which can be orally administered is available on the market.

Since the activated blood coagulation factor X is positioned at the juncture of an extrinsic coagulation cascade reaction and an intrinsic coagulation cascade reaction and in the upstream of thrombin, it is possible to inhibit the coagulation system more efficiently and specifically, than the thrombin inhibition, by inhibiting the factor X (Tidwell, R.; Webster, W. P.; Shaver, S. R.; Geratz, J. D. THROMBOSIS RESEARCH, Vol. 19, pages 339 to 349; 1980).

Determination of Activity of inhibiting the Activated Blood-coagulation Factor X

130 μl of 100 mM tris hydrochloride buffer adjusted to pH 8.4 was added to 10 μl of an aqueous solution of a compound to be tested. Then 10 μl of a 0.5 unit/ml solution of activated human blood coagulation factor X (a product of Enzyme Research Co.) in tris hydrochloride buffer of pH 8.4 was added to the resultant mixture. After the incubation at room temperature for 10 minutes, 50 μl of a solution of N-benzoyl-L-isoleucyl-L-glutamyl-glycyl-L-arginyl-P-nitroanilide hydrochloride (a product of Peptide Institute Inc.) adjusted to 0.8 mM with tris hydrochloride (pH 8.4) was added thereto. The a absorbance was determined and then the initial reaction rate was determined. A control was prepared in the same manner as that described above except that the solution of the compound to be tested was replaced with 10 μl of tris hydrochloride buffer adjusted to pH 8.4. The absorbance was determined with MICROPLATE READER Model 3550-UV (a product of BIO RAD) at a wave length of 405 nm at intervals of 15 seconds for 16 minutes. The negative logarithm (pIC

50

) of a concentration of the test compound which inhibits 50% of the activity (initial rate) of the activated blood coagulation factor X in the absence of the test compound was determined, and employed as the index of the activity of inhibiting activated blood coagulation factor X. The activities, of inhibiting activated blood coagulation factor X, of typical compounds are shown in Table 1 given below.

Example 210

Determination of Thrombin-inhibiting Activity

130 μL of 100 mM tris hydrochloride buffer adjusted to pH 8.4 was added to 10 μl of an aqueous solution of a test compound. Then 10 μl of a solution of human thrombin (a product of SIGMA Co.) adjusted to 2 units/ml with tris hydrochloride buffer of pH 8.4 was added to the resultant mixture. After the incubation at room temperature for 10 minutes, 50 μl of a solution of D-phenylalanine-L-pipecolyl-L-arginine-P-nitroanilide dihydrochloride (S-2238; a product of Daiichi Kagaku Yakuhin Co.) adjusted to 0.4 mM with tris hydrochloride buffer of pH 8.4 was added thereto. The absorbance was determined and then the initial reaction rate was determined. A control was prepared in the same manner as that described above except that the solution of the compound to be tested was replaced with 10 μl of tris hydrochloride buffer adjusted to pH 8.4. The absorbance was determined with MICROPLATE READER Model 3550-UV (a product of BIO RAD) at a wave length of 405 nm at intervals of 15 seconds for 16 minutes. The negative logarithm (pIC

50

) of a concentration of the test compound which inhibits 50% of the activity (initial rate) of the thrombin in the absence of the test compound was determined, and employed as the index of the activity of inhibiting thrombin. The activities, of inhibiting thrombin, of typical compounds are shown in Table 1 given below.

Example 211

Determination of Blood Anticoagulating Activity

The blood anticoagulating activity was determined by a prothrombin time (PT) determination method. The PT was determined as follows: The blood was taken from healthy people. 3.8% aqueous trisodium citrate solution was added to the blood in a volume ratio of 1:10. The blood plasma was separated by the centrifugation. 5 μl of DMSO solution containing a test compound was added to 45 μl of the blood plasma. After the incubation apt room temperature for 2 minutes, a test tube containing the blood plasma solution was placed in Sysmex CA-3000 fully automatic blood coagulation determination device (a product of Toa Medical Electronics Co., Ltd), and incubated at 37° C. for 3 minutes. 100 μl of Sysmex PT II (rabbit brain tissue thromboplastin, 13.2 mM calcium chloride; a product of Toa Medical Electronics Co., Ltd) was fed into the test tube. PT was automatically determined with the device. A sample containing 5 μl of DMSO in place of the solution of the test compound was used as the control. The negative logarithm (pPT2) of the concentration of the test compound which elongated PT of the control to the twice as long was determined, and employed as the index of the blood anticoagulating activity.

The structural formulae of the compounds of the present invention described in the Examples are given below.

The blood coagulation inhibitor containing a compound of the present invention or a salt thereof as the active ingredient has a blood-coagulation inhibiting effect based on the excellent effect of inhibiting activated blood-coagulation factor X. In addition, the blood coagulation inhibitor containing a compound of the present invention or a salt thereof as the active ingredient also has a high oral absorbability. Therefore, the compounds of the present invention are usable as agents for preventing or treating diseases, for example, cerebrovascular disorders such as cerebral infarction, cerebral thrombosis, cerebral embolism, transient ischemic attack (TIA) and subarachnoidal hemorrhage (vasospasm); ischemic heart diseases such as acute and chronic myocardial infarction, unstable angina and coronary thrombolysis; pulmonary vascular disorders such as pulmonary infarction and pulmonary embolism; peripheral arterial occlusive disease; deep vein thrombosis; disseminated intravascular coagulation; thrombus formation after an artificial blood vessel-forming operation or artificial valve substitution; reocclusion and restenosis after a coronary artery bypass grafting; reocclusion and restenosis after reconstructive operation for the blood circulation such as percutaneous transluminal coronary angioplasty (PTCA) or percutaneous transluminal coronary recanalization (PTCR); and thrombus formation in the course of the extracorporeal circulation.
