Description

Novel benzoazepine derivatives and their medical uses

The present invention relates to a novel benzoazepine derivative which is useful as a pharmaceutical and a medical use thereof. This compound has various medical uses as a V2 receptor agonist.

Arginine Vasopressin is a peptide containing nine amino acids that is biosynthesized in the hypothalamus and secreted from the posterior pituitary gland. The receptors for arginine superscriptin are classified into three subtypes: V1a, V1b and V2. V1a receptors are found in liver, muscle vascular cells, platelets, peripheral tissues and the central nervous system. V1b receptors are present in the central nervous system. In addition, another V2 receptor is present in the renal collecting duct cells. If ginsenoside is combined with the V2 receptor, it will promote the reabsorption of water in the renal collecting duct and reduce the amount of urine. Therefore, if the arginine vasopressin is insufficient, polyuria is exhibited, and the diseases caused thereby include central diabetes insipidus, nighttime enuresis in children, nocturnal urinary frequency, and overactive bladder. Therefore, V2 receptor agonists are useful as prophylactic or therapeutic agents for such diseases. Further, since the V2 receptor agonist has a blood factor VIII and a Wyberber's factor release action, it can be treated for a bleeding disease (hemophilia, Von Wylie disease, etc.).

Previously, as a V2 receptor agonist, it will act as a peptide of Desmopressin (removal of the amino group of cysteine at position 1 of arginine pressor and conversion of arginine at position 8) For d-type patients) for the treatment of central diabetes insipidus and nocturnal enuresis. However, the bioavailability of the desmopressin oral agent is very low, and a higher amount is required in order to obtain an effect. Further, the desmopressin preparation is relatively expensive, and the occurrence of side effects caused by the absorption deviation between individuals is worrying, and may not be satisfactory in terms of safety. therefore, It is expected to create medicines with higher bioavailability and less absorption deviation.

On the other hand, the metabolic reaction caused by cytochrome P-450 (CYP) plays a major role in the disappearance of the drug from the body. It can be considered that if the drug of the CYP metabolism of the same molecular species competes on its metabolic enzyme, it is subject to a certain Metabolic inhibition. If the CYP is inhibited, it may cause a change in the concentration of the drug in the blood and tissues, a change in the therapeutic effect, and a serious side effect. Therefore, it is desired to create a medicine which has low affinity for CYP and less concern for enzyme inhibition.

Benzene heterocyclic derivatives (Patent Documents 1 to 3), benzoazepine derivatives (Patent Documents 4 to 5), and guanamine have been reported as compounds having an vasopressin receptor agonistic effect. Derivatives (Patent Document 6) and benzodiazepine derivatives (Patent Document 7), as a compound having an angiogenic receptor antagonism, a substituted spirobenzoazinium derivative has been reported (Patent Document 8) However, such compounds are structurally different from the compounds of the invention having a carbonyl group on the carbon at the 4-position of the benzazepine.

Pharmacological test (1) Production of human V2 receptor expressing cells

Inserting a DNA fragment containing a human V2 receptor coding region into a vertebrate cell In the expression vector. The gene is introduced into animal cells to express human V2 receptor on the cell surface. The expression vector can express the neo gene functioning as a G418 resistance marker, and thus the human V2 receptor stably expressing cells can be selectively obtained by culturing in a medium containing G418.

(2) cAMP production test in V2 receptor-expressing cells

The human V2 receptor-expressing cells prepared by the above method were recovered, and after resuspending in a culture buffer (F-12 medium, 20 mM HEPES), 5 μl of the cells were dispensed to 384 wells at a density of 15,000 cells/well. In the board. Add 5 μl (10 μl/well) of compound solution diluted in assay buffer (F-12 medium, 20 mM HEPES, 1 mM IBMX) or 8-AVP ((Arg ⁸ )-vasopressin) solution to each well (final Concentration: 15,000 cells/well, 500 μM IBMX, 1% dimethylammonium). After incubation at room temperature for 30 minutes, the amount of cAMP production was measured according to the stated protocol using a commercially available HTRF cAMP kit (Cisbio). Excel Fit was used to determine the EC ₅₀ and Emax values of the test compounds. The Emax value of the test compound was calculated by setting the maximum reaction of 8-AVP to 100%, and based on the concentration-response curve of the test compound, the value showing the reaction of 50% was taken as the EC ₅₀ value, and the obtained EC ₅₀ was obtained. The Emax values are shown in Table 10.

As a result, it was found that all of the compounds of the examples subjected to this test had V2 receptor agonist activity.

(3) Rat PK (pharmacokinetics, pharmacokinetics) test

As experimental animals, male Sprague-Dawely (Crj: CD (SD) IGS: Charles River Laboratories Japan Co., Ltd.) rats of 7 to 8 weeks old were used. Rats used a hunger strike overnight. After the test compound was dissolved in DMSO, PEG (polyethylene glycol) and physiological saline were added to prepare at a concentration of 0.5 mg/mL (20/20/60, v/v/v) to 0.5 mg/ The amount of kg is administered to the tail vein. Blood was collected from the jugular vein by a heparin-treated syringe over a period of 6 to 8 hours after the administration, and the blood taken was centrifuged to obtain plasma. The concentration of the drug in the plasma was determined using LC/MS/MS. The sample for LC/MS/MS measurement was obtained by adding an internal standard substance and acetonitrile to plasma and removing the supernatant from the protein. PK parameters were analyzed using a non-compartmental model. The clearance rate (CL _p ) was calculated by dividing the AUC _0-∞ by the amount of administration. The distribution volume (Vd _ss ) is calculated by multiplying CL _p by the average residence time (MRT). The obtained CLp and Vd _{ss are} shown in Table 11.

As a result, it was found that all the compounds of the examples subjected to this test had good plasma clearance and distribution volume, and were excellent in dynamics.

Further, the comparative compound 2 is a compound of Example 32 described in International Publication No. 97/22591 (Compound: 2-[(5R)-1-(2-chloro-4-pyrrolidine-1-) Benzomethylene)-2,3,4,5-tetrahydrobenzoazin-5-yl]-N-isopropylacetamide).

[Industrial availability]

The compound of the present invention has a V2 receptor agonistic action and is therefore useful as a preventive or therapeutic agent for central diabetes insipidus, nocturnal enuresis, nocturnal urinary frequency, overactive bladder, hemophilia, or Von Wylie disease.
