DERIVATIVES OF AMIN 1- [í?) - (3, 4-DIHIDRO-2-NAFTALENIL) ALQUIL] -CÍCLICA, PROCESS FOR YOUR PREPARATION AND PHARMACEUTICAL COMPOSITIONS THAT CONTAIN THE SAME "
FIELD OF THE INVENTION
The present invention relates to a new cyclic alkylene derivative 1- £ G * - (3, 4-dihydro-2-naphthaleniDJ) which shows an inhibitory effect on the micturition reflex, a process for preparing it and a pharmaceutical composition containing them.
contains them.
BACKGROUND OF THE ART Until now there are many reports about amine derivatives l - [α- (3,4-dihydro-2-naphthalenyl) alkyl]
cyclical
However, as far as the known reports of current inventors, amine derivatives l - [α- (3,4-dihydro-2-naphthalenyl) alkyl] cyclic are known in which the alkyl portion is ethyl, only the next time. That is, Pharmazie, 42, 369 (1987) discloses that l- [2 (3,4-dihydro-2-hydrochloride
REP 25784 naphthalenyl) ethyljpiperidine shows a very low affinity for the dopamine receptor ip vi tro.
The following compounds are known as a
amine derivative l - [? - (3,4-dihydro-2-naphthalenyl) alkyl] cyclic wherein the alkyl portion is a methyl.
USP 4,022,791 discloses that the compound of the following formula is employed as an analgesic and tranquilizing agent, and the role of almost the same content is reported in J. Med. Chem., 21, 257 (1978).
wherein X and Y are independently H, F, Cl, Br, an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms, and Z is a secondary or tertiary amino group , provided that X and Y are not simultaneously H. In addition, Chem. Pharm. Bull., 31, 2006 (1983) describes that hypotensive activities and
vasodilation of l - [(3,4-dihydro-6-morpholino-2-naphthalenyl) methyl] piperazine and 4-benzyl-l - [(3,4-dihydro-6-morpholino-2-naphthalenyl) methyl] piperidine were tested using dogs and hypertensive rats spontaneously.
With the arrival of the increase in the age of people in society, year after year the number of patients suffering from frequent urination and urinary incontinence tends to increase. At present, three drugs, namely flavoxate, oxybutynin and propiverine, are used clinically in the treatment of these conditions, in smaller quantities than drugs for treatment of frequent urination and urinary incontinence accompanied by prostatic heterotrophy. All these drugs expose their pharmacological activity (increases the capacity of the bladder volume) based on the relaxation of the smooth muscle of the bladder, and are not necessarily satisfactory in terms of less efficacy and difficulty for use in the case of frequent urination. urinary incontinence which is accompanied by urethral obstruction (difficulty in urination) as well as side effects.
Under the circumstances, the development of medications for the treatment of frequent urination and urinary incontinence via a central mechanism, which is different from current or existing medicines that have been tested. For example, 1-4 (-ethylphenyl) -2-methyl-3- (1-pyrrolidinyl) -1-propanone hydrochloride (generic name: inaperisone hydrochloride), which is a central muscle relaxant (cf., Drugs Fut., 18, 375 (1993)) have been reported to be effective for symptoms such as neurogenic bladder, unstable or irregular bladder, and neural polaquisuria (cf., Nishinihon J.Urol., 54, 1472 and 1820 (1992)). However, the improvement of the efficacy and side effects thereof may not necessarily be sufficient. The present inventors have studied intensively and have found that the amine derivative 1 - [α- (3,4-dihydro-2-naphthalenyl) alkyl] cyclic of the following formula (I) exhibits an immediate potent inhibitory effect mainly via a central mechanism in the reflection of the micturition, and some of the compounds (I) show their powerful inhibitory effect on the reflex of micturition without side effects such as depression in the central nervous system and inhibition of the spinal reflex.

Experiment 1 Inhibitory effect on rhythmic contractions of the bladder (reflex of micturition)
The experiment was carried out according to the method of Maggi, C.A. and Meli, A. [J: Pharmacol.Methods, 10, 79 (1983)]. It is generally accepted that the rhythmic contractions of the bladder evoked by the instillation of saline solution within the bladder are mediating via the micturition reflex, a path similar to that of natural urination.
Female Std-Wistar rats weighing 160-190 g were used in groups of 3-4 animals. Under urethane anesthesia (1 g / kg, s.c.) both uteri were attached and cut laterally to the kidney after a half line of incision in the abdomen. A probe connected to the kidney was inserted through the external urethral orifice.
a syringe and a pressure transducer and ligated around the proximal urethra. The animal remained that way for approximately 30 minutes after the operation. The bladder was slowly emptied with heated saline (0.4-1 ml) by means of a syringe to induce rhythmic contractions. The change in intravesicular pressure was recorded on a recorder via pressure transducer. After the rhythmic contractions were constant, the test compounds were dissolved or suspended in 0.5% aqueous tragacanth solution, administered via the inserted probe by intraduodenal administration. The effect of each compound on the contractile frequency was investigated every 15 minutes even two hours after administration.
Table 3 shows the inhibitory effect on the contractile frequency (two hours) at prescribed doses of each test compound or the doses of compound test required for 50% inhibition of the contractile frequency (ED50 value). The inhibitory rate in the contractile frequency (two hours) was expressed as the mean value of the inhibitory rates at a 15-minute interval for two hours after administration, which was determined based on the contractile frequency for 15 minutes before the administration. administration. The ED50 value was determined by the Litchfield-Wilcoxon method [J. Pharmacol. Exp. Ther.,
96, 99 (1949)] based on the rates of inhibitory frequency (two hours) contractile at each dose.

As is clear from Table 3, all of the compounds of the present invention tested in this experiment markedly expose the inhibitory effects on the frequency of rhythmic contractions of the bladder. Especially the effects on the compounds of Examples 1 and 2, which were about 8 times more potent than those with inaperisone hydrochloride (Compound A). Additionally, the effects on the compounds of examples 62.68, 4, 36 and 43 were approximately 5.7, 4.7, 3.3 and 3 times more potent compared to those of inaperisone hydrochloride respectively.
In addition, the compounds of Examples 2, 3, 4, 12, 20, 26, 36, 41, 43-47, 49, 50, 56, 62, 68 and 72 not only expose the inhibition of contractile frequency, but also they suppress the amplitude of the contraction.
Experiment 2 Effect on contractions of the bladder induced by pelvic nerve stimulation.
Std- istar male rats weighing 250-350 g were used. Under urethane anesthesia (1 g / kg, ip) both uteri were attached and cut laterally to the kidney after a midline incision in the abdomen. When the peripheral end of the pelvic nerve was stimulated, one side of the pelvic nerve was cut off. When the end of the central cut of the nerve was stimulated, one side of the pelvic nerve was cut similarly to the peripheral end and then both stimulations of the hypogastric nerve were cut. Then, the bladder was exposed, the probe connected to a syringe and a pressure transducer, was inserted into the bladder via a small incision at one apex of the abdomen, and then the proximal urethra was ligated. Fifteen minutes after the operation, a warm saline solution in an amount (0.1-0.2 ml) being small enough not to cause rhythmic contraction, was introduced into the bladder using a syringe.
The change in intravesical pressure was recorded on a recorder via a pressure transducer. The pelvic nerve was stimulated and cut to the final periphery or center once by a pair of platinum electrodes with pulses of duration 1 msec, 3v force and a frequency of 10 Hz (per periphery) or 5 v of force and a frequency of 20 Hz (per center), for 5 seconds every 2 minutes. The test compounds dissolved in distilled water were injected at a dose of 5 mg / kg via the probe inserted into the jugular vein.
Table 4 shows the inhibitory rate of the test compounds in the contractions at 2.40, 10 and 20 minutes after the administration of the test compounds which was calculated as compared to the control response before the administration of the compound test, and was compared with those of the vehicle (distilled water) and treated group (unpaired t-test). Each value in the table is medium + standard error of males in 3-4 animals.

As is clear from Table 4, the effects of the compounds of Examples 1, 2 and 43 on bladder contractions induced by stimulation of the central and final cut were more potent than those in contractions induced by stimulation of the bladder. cut in the final periphery. The result arises that the effects of the compounds of the invention can be measured immediately via the central nervous system.
Experiment 3: Inhibitory effect on exploratory operation. Male Std-Wistar rats weighing 150-200 g were used in groups of 5 animals. One hour after oral administration of the test compounds suspended in 0.5% aqueous tragacanth solution, the animals were placed individually in a test box (23x35x30 cm) in an Animex activity counter (Farad Co., Switzerland). Immediately afterwards, the counting machine was started and continued for three minutes.
The mean value of the exploratory operation (cont / 3 minutes) in the test compound was determined with the treated groups, and the inhibitory effect of each test compound was calculated compared to that of the control group (0.5% aqueous tragacanth solution per group). treated). The results are shown in Table 5 together with the results of experiments 4 and
. Experiment 4: Inhibitory effect on the polysynaptic spinal reflex.
The experiment was carried out in accordance with the method of Itoh, et. to the. [Japan J. Pharmacol., 23, 1125
(1982)]. Male Std-Wistar rats weighing 250-350 g were used in groups of 4-6 animals. Under anesthesia combined with i.p. urethane injection (400 mg / kg) and a-chloralose (50 mg / kg), rats fixed in a stereotactic apparatus were screwed to the spine and tibia. A concentric needle electrode was inserted into the left gastronemius muscle, and the final end of the common peroneal nerve ipsilateral to the same side was stimulated supramaximally by an electrical stimulator (rectangular pulse, 0.1 msec, 0.1 Hz). The test compounds dissolved in distilled water were injected via the inserted probe into the right femoral vein, and the evoked electromyogram was recorded periodically (2, 5, 10, 20 and 30 minutes after the injection). The inhibitory effect of the test compounds on the amplitude of the evoked electromyogram was expressed as a percentage against the amplitude before administration and then, the ID50 value (the dose required for 50% inhibition of amplitude) was calculated in accordance with the Litchfield-ilcoxon method based on the maximum inhibitory ratio at each dose. The results are shown in table 5 together with the results of experiments 3 and 5. Experiment: 5 Acute toxicity
Male ddY mice weighing between 18-25 g were used in groups of 5-15 animals. The test compounds were suspended in 0.5% aqueous tragacanth solution administered orally, and mortality was investigated for 7 days followed by administration. The LDso value (50% lethal dose) was calculated according to the Litchfield-Wilcoxon method. The results are shown in Table 5 together with the results of experiments 3 and 4.

Comp. 500 mg / kg 28.3% 4.22 mg / kg 458 mg / kg
As is clear from Table 5, the inhibitory effects of the compounds of Examples 1 and 2 on the exploratory operation were less potent than those of compound A, and the inhibitory effect of the compound of Example 43 on the exploratory operation was almost the same as that of compound A. In the spinal reflex experiment, the inhibitory effect of the compound of Example 43 was about the same as compound A, but the effects of the compounds of examples 1 and 2 were more deficient than those of compound A. The acute toxicity of the compound of Example 43 was approximately two times smaller than that of compound A, and those of the compounds of Examples 1 and 2 were also lower than those of compound A.
Judging as a whole from these results and the results of Experiment 1, the inhibitory effects of the compounds of Examples 1,2 and 43 on the rhythmic contractions of the bladder (micturition reflex) are extremely separated from the effects laterals such as central depression and inhibition of the spinal reflex, and toxicity, compared with those of compound A.
