Effect of the Invention

The compound of the present invention has a D₂ receptor partial agonist effect, a 5-HT_2A receptor antagonist effect and a serotonin uptake inhibitory effect (or serotonin reuptake inhibitory effect).

The D₂ receptor partial agonist effect suppresses dopaminergic (DA) neurotransmission when it is enhanced, and accelerates the DAergic neurotransmission when it is lowered and thus has a function to stabilize the DA neurotransmission to a normal state (dopamine system stabilizer). According to this function, excellent clinically improving effect on the abnormal DA neurotransmission (enhancement and lowering), for example, improving effect on positive and negative symptoms, improving effect on cognitive impairment, improving effect on depressive symptom etc. are developed without causing side effects (see Michio Toru: Clinical Psychiatry, vol. 46, pages 855-864 (2004), Tetsuro Kikuchi and Tsuyoshi Hirose: Brain Science, vol. 25, pages 579-583 (2004), and Harrison, T. S. and Perry, C. M.: Drugs 64: 1715-1736, 2004).

5-HT_2A receptor antagonist effect reduces extrapyramidal side effects, develops superior clinical effects, and is effective, for example, for improvement of negative symptoms, improvement of cognitive impairment, improvement of depressive symptom, improvement of insomnia and the like (see Jun Ishigooka and Ken Inada: Japanese Journal of Clinical Psychopharmacology, vol. 4, pages 1653-1664 (2001), Mitsukuni Murasaki: Japanese Journal of Clinical Psychopharmacology, vol. 1, pages 5-22 (1998), Pullar, I. A. et al.: Eur. J. Pharmacol., 407: 39-46, 2000, and Meltzer, H. Y. et al.: Prog. Neuro-psychopharmacol. Biol. Psychiatry 27: 1159-1172, 2003).

Serotonin uptake inhibitory effect (or serotonin reuptake inhibitory effect) is effective, for example, for improvement of depressive symptom (see Mitsukuni Murasaki: Japanese Journal of Clinical Psychopharmacology, vol. 1, pages 5-22 (1998)).

The compound of the present invention is excellent in all of these three effects, or remarkably excellent in one or two of these effects.

In addition, some of the compounds of the present invention have α₁ receptor antagonist effect in addition to the above-mentioned effects.

Experimental Example 2; Pharmacokinetics of Intramuscular Preparations

A suspended fine particle preparation used as a sustainable injection requires re-suspending before administration, and the particle surface area markedly affects the drug release profile. Thus, the particle size after re-suspending needs to be strictly controlled, so that coagulation and the like will not occur.

On the other hand, since an oil-soluble preparation contains a drug completely dissolved therein, re-suspending before administration is not necessary and, since the drug is released depending on the oil-water distribution coefficient, control of the particle size is not necessary. Furthermore, since sterilization by filtration, which has been unattainable for suspended fine particle preparations, has become possible, a preparation can be prepared more conveniently.

Since the compound disclosed in patent document 1 shows low solubility in an oil base material such as benzyl benzoate and the like, an oil-soluble preparation cannot be produced. When a soluble preparation is produced, an aqueous base material using a solubilizing agent such as Captisol (Sulfobutylether-β-cyclodextrin) and the like needs to be used. In contrast, since the compound of the present invention shows high solubility in an oil base material, an oil-soluble preparation can be produced.

Thus, an oil-soluble preparation of the compound of the present invention and an water soluble preparation of the compound disclosed in patent document 1 were prepared, intramuscularly administered to rats and pharmacokinetics of these preparations were evaluated.

Animal

7-week-old male rats were purchased from CHARLES RIVER LABORATORIES JAPAN, INC, preliminarily bred and rats weighing 265.2 g-288.6 g were used for the experiment. The experiment was performed under the conditions of no fasting, free access to water and feed, and the following breeding environment. Rats per cage: 4, temperature: 23±2° C., humidity: 60±10%, light-on time: 7:00-19:00

Production Method of Preparation

As the compound disclosed in patent document 1, used was 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one (control compound) disclosed in Example 1 that expresses desired efficacy. A water-soluble preparation was obtained by dissolving the control compound in aqueous 15% Captisol and 0.78% tartaric acid solution to a concentration of 0.5%, and the pH was adjusted to 4.3 with 5N aqueous sodium hydroxide solution.

An oil-soluble preparation was obtained by dissolving the compound of the present invention disclosed in Example 146 in benzyl benzoate to a concentration of 15%, and adjusted.

Methods of Administration and Blood Sampling

Under isoflurane anesthesia, non-fasting male rats were intramuscularly administered at left leg region (about 4 mm depth) using a syringe with 24 G needle. The dose is as described below.

Test preparation 1: low dose of oil-soluble preparation of the compound of the present invention: 25 mg/kg (based on control compound)
Test preparation 2: high dose of oil-soluble preparation of the compound of the present invention: 50 mg/kg (based on control compound)
Test preparation 3: water-soluble preparation of control compound: 0.1 mg/kg

The test preparation was administered to the rats. For test preparation 3, about 0.3 mL each of blood samples were collected from the jugular vein 5 min, 15 min, 30 min, 1 hr, 2 hr, 4 hr and 20 hr later. For test preparations 1 and 2, about 0.3 mL each of blood samples were collected from the jugular vein 6 hr, 1 day, 3 days, 7 days, 14 days, 21 days and 28 days later. For collection of blood samples, a 1 mL syringe treated with EDTA-lithium fluoride-heparin was used. The collected blood was preserved under ice-cooling, the plasma was rapidly separated by centrifugation, and the concentration of the control compound was quantified by LCMS. The pharmacokinetics parameters such as Cmax, Tmax, AUClast, AUCinf, t½ and the like were determined by WinNonlin Professional Version 6.1 (model-independent method, Pharsight corporation).

Results

The results are shown in FIG. 1 (blood concentration profile of control compound after administration of test preparations 1, 2 and 3) and Table 5 (pharmacokinetics parameters of test preparations 1, 2 and 3).

TABLE 5
	Cmax	Tmax	AUClast	AUCinf	t1/2
	(μg/mL)	(day)	(μg · day/mL)	(μg · day/mL)	(day)
Test preparation 1	0.0258	5.00	0.270	0.473	27.99
Test preparation 2	0.0423	5.31	0.480	0.621	16.99
Test preparation 3	0.0629	0.01	0.003	0.003	0.05
Each parameter shows mean value (n = 4)

Discussion

In test preparation 3, the control compound disappeared immediately after intramuscular administration. On the other hand, in test preparations 1 and 2, the control compound showed a sustained blood concentration profile. Therefrom it was shown that the improved solubility of the compound of the present invention in an oily substrate has enabled the production of a dissolution preparation that shows blood concentration sustainability of the compound of patent document 1.
