In [Formula [], R A represents a hydrogen atom or a phenyl group, and the phenyl group may be substituted with a hydroxy group or a nitro group. R B represents a hydroxy group or a lower alkoxy group, and the lower alkoxy group may be further substituted with a phenyl group. R C represents either a hydroxy group, a lower alkoxy group, an amino group, a hydroxyamino group or [Formula]. Q 1 represents a sulfur atom or a methylene group. A represents -X-Y-Z-. X represents a linear or branched lower alkylene group which may be substituted with a phenyl group. Y represents [Formula] -CO-, -S-, [Formula] -SCH 2 CO-, [Formula] or a single bond. R D represents a hydrogen atom, a lower alkyl group, a lower alkanoyl group, or a phenyl lower alkanoyl group, and the lower alkyl group may be further substituted with a phenyl group, a carboxyl group, or a lower alkoxycarbonyl group. Z represents a linear or branched lower alkylene group or [Formula], and the lower alkylene group may be substituted with a lower alkanoyl group, phenyl group, or phenylcarbonyl group. However, under the condition that Y represents -S- or a single bond, if the group adjacent thereto represents a lower alkylene group, the alkylene group does not represent a linear lower alkylene group. However, this does not apply when R C represents a hydroxyamino group. ] The compound of the present invention [ ] inhibits the enzyme - aldose reductase, and is effective in preventing various diseases caused by diabetes (e.g., diabetic cataract, diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, etc.). It is useful as a therapeutic agent. Diabetic complications (e.g. diabetic cataracts, diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, etc.)
It is known that the enzyme aldose reductase is involved in this [JHKinoshita et al.
Jap.J.Ophtalmol., 20 , 399 (1976)]. The enzyme aldose resectase converts aldoses (glucose and galactose) into sugar alcohols, polyols (sorbitol and galactitol), and the accumulation of these sugar alcohols is thought to cause tissue cell swelling and damage. [R. Quan-Ma et al., Biochem. Biophys.
Res.Comm., 22 , 492 (1966)]. For example, diabetic cataracts are caused by the accumulation of sugar alcohols in the crystalline lens [R. Gitzelman et al.
Exptl. Eye Res., 6 , 1 (1967)]. Thus, suppressing the production of sugar alcohols that cause systemic damage has the effect of preventing and treating various diseases that occur as a complication of diabetes. As described below, the compound of the present invention suppresses the activity of the enzyme aldose reductase, suppresses the production of sugar alcohol, and exhibits preventive and therapeutic effects on diabetic complications. On the other hand, in addition to the above-mentioned effects, the compound of the present invention [ ] has a blood pressure lowering effect because it strongly inhibits angiotensin-converting enzyme, and is extremely useful as a medicine. Although it is known that certain thiazolidine or pyrrolidine derivatives have angiotensin converting enzyme inhibitory activity, the compound of the present invention [] is a new compound, and as a result of intensive research, it has been found that it has a stronger angiotensin converting enzyme inhibitory activity. found. Furthermore, the compound of the present invention [] can be synthesized by a simple method and has extremely excellent stability. Typical production examples of the compound of the present invention [] are shown below. a General formula In [Formula [], when R A and R B contain a reactive group, they can be protected with a suitable protecting group (eg, lower alkyl group, acyl group, aralkyl group, aralkyloxy group, etc.). ] and the general formula HOOC-A-CO-R C [] [In the formula [], when A and R C contain a reactive group, a suitable protecting group (for example, a lower alkyl group, an acyl group, aralkyl group, aralkyloxy group, etc.). ] Reactive derivatives of carboxylic acid compounds (e.g., acid halides, acid anhydrides, mixed acid anhydrides,
active esters, lactones, etc.) by general methods commonly used in peptide synthesis or amidation reactions, and then, if necessary, by standard methods (e.g., hydrolysis, reduction, ammonolysis, alcoholysis, etc.). The compound of the present invention [ ] can be obtained by carrying out a deprotection reaction using (etc.). This deprotecting group operation is also applied in the following production method. b Compounds represented by the general formula [] and the general formula HOOC-A 1 -L [] (In the formula [], A 1 is -X-, -X-Y-,

The effect of the thiazolidine compounds of the present invention on reductase was measured according to the method of JHKinoshita [Invest. Ophthal., 13 , 713 (1974)]. The total volume of the reaction solution for measuring aldose reductase activity was 3.0 ml [0.007M phosphate buffer (PH6.2),

×10 −4 M DL-glyceraldehyde, 10 U aldose reductase enzyme, 10 −4 to 10 −10 M compound of the present invention], and the absorbance at 340 nm was measured. The results are shown in the table below. [Table] [Table] Pharmacological Test 2 Methods for measuring angiotensin converting enzyme activity include biological assays that measure isolated smooth muscle contraction activity or blood pressure increase effects in normal animals, and animal lung or other There is a chemical assay method using enzymes isolated and purified from tissue.
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 at 90°C via 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 decomposes bradykinin, which has the effect of contracting the guinea pig ileum, that is, kinin-degrading enzyme, is the same as angiotensin-converting enzyme. Since it is,
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. Results 50% inhibition of angiotensin contractile action or 50% inhibition of bradykinin contractile action of many compounds of the present invention.
The concentration of % enhancement was between 10 -7 and 10 -9 M. Pharmacological Test 3 As a method for measuring angiotensin converting enzyme activity, Biochem.Pharmacol., 20 . 1637 (1971) using the spectrophotometric method. The principle is hipryl-L-histidyl-L-leucine (HHL) 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℃ 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 on angiotensin converting enzyme 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 x 10 -9 M, calculate the inhibition rate at each concentration using the above formula, and calculate the concentration of the compound required to inhibit the enzyme activity by 50% (IC 50 ). did.
