This is clear from the results of comparing the pharmacological actions of known compounds and the compound of the present invention. It has been shown that drugs that inhibit angiotensin-converting enzyme, which converts the biologically inactive decapeptide angiotensin to the active octapeptide angiotensin, can be used to treat hypertension. Based on this, the pharmacological effects of antihypertensive drugs were investigated using the enzyme inhibition as an indicator. Pharmacological test example 1 Methods for measuring angiotensin converting enzyme activity include biological assays that measure dripping, smooth muscle contraction, or blood pressure increase in normal animals as indicators, and angiotensin-converting enzyme activity that is isolated from animal lungs or other tissues. There is a chemical assay method using purified enzyme, but
It has been revealed that the former method is advantageous for understanding the conversion of angiotensin to angiotensin in vivo. Therefore, in this experiment, a method was used in which the contraction of the guinea pig's isolated ileum, which occurs after the action of angiotensin, was used as an index. Angiotensin-converting enzyme inhibition effect measurement method A guinea pig isolated ileum specimen was prepared according to a conventional method, suspended in an organ bath containing 20 ml of Tyrode's solution heated to 30°C, and 95% O 2 + 5% CO 2 gas was aerated. angiotensin (final concentration) at 10 minute intervals.
0.1 μg/ml) and the generated contractile force was measured using an FD pickup (Nihon Kohden, ST-1T-H).
The time was recorded on a second recticcorder (Nihon Kohden). The test drug was applied 5 minutes before the addition of angiotensin. The angiotensin converting enzyme inhibitory effect was determined using the following formula. A-B/A×100 A: Contraction strength of angiotensin before drug action B: Contraction strength of angiotensin after drug action In addition, the enzyme that degrades bradykinin, which has the effect of contracting the guinea pig ileum, ie, kinin-degrading enzyme, is angiotensin-converting enzyme. Since they are the same, bradykinin (0.005 μg/ml) was used as a contractile substance instead of angiotensin, and the bradykinin contractility enhancing effect of the test drug was assayed by the method described above. The experimental results are shown in Table 1. All of the tested drugs inhibit the contractile action of angiotensin and enhance the contractile action of bradykinin. Pharmacological test example 2 As a method for measuring angiotensin converting enzyme activity, Biochem.Pharmacol., 20 . 1637 (1971) using the spectrophotometric method. The principle is that hipryl-L-histidyl-L-leucine (HHL) is used as a substrate.
When it is reacted with angiotensin-converting enzyme extracted from rabbit lung, hippuric acid is liberated, and the absorbance of the liberated hippuric acid is measured. Method for measuring angiotensin-converting enzyme inhibition effect The reaction was carried out under the following reaction conditions. 100mM phosphate buffer (PH8.3) 300mM Sodium chloride 5mM HHL 10 -3 - 10 -9 M Enzyme inhibitor 5mU Enzyme solution After reacting 0.25ml of the above solution at 37°C for 30 minutes, add 0.25ml of 1N hydrochloric acid. Stop the reaction, add 1.5 ml of ethyl acetate to extract hippuric acid, take 1.0 ml of the ethyl acetate layer, evaporate to dryness, add 1.0 ml of water, and measure the absorbance at a wavelength of 228 nm. The inhibitory effect of angiotensin-converted hypothermia was determined using the following formula. Inhibition rate of compound = AB/A x 100 A: Absorbance of reaction solution B: Absorbance when compound is added to reaction solution Concentration of compound required to inhibit angiotensin converting enzyme by 50% (IC 50 ) 1 x 10 Add and react compounds at various concentrations from -3 M to 1×10 -9 M, calculate the inhibition rate at each concentration using the above formula, and calculate the concentration of the compound required to inhibit enzyme activity by 50% (IC 50 ). did.

む。[Table] Concentration of Compound Required for Compound Concentration As is clear from the above pharmacological tests, the compound of the present invention [ ] is useful as an antihypertensive agent. In that case, it may optionally be combined with a diuretic, as is currently common practice. The administration form may be either oral or parenteral administration, and therapeutic preparations include tablets, capsules, granules, powders, suppositories, and injections.
In addition to the usual fillers, especially in the treatment of hypertension, these preparations can also contain antihypertensive agents such as reserpine, alpha-methyldopa, guanethidine, clonidine or hydrazine. The dosage varies depending on symptoms, administration method, etc., but is usually 1 to 5000 mg per day, preferably 10 to 1000 mg per day.
