TECHNICAL FIELD

The present invention relates to a quinuclidine derivative, and to a medicament containing the quinuclidine derivative.

BACKGROUND ART

Chronic obstructive pulmonary disease (COPD) is a generic term for diseases that have been conventionally called chronic bronchitis or emphysema. COPD is a chronic disease of the lungs, which is caused by long-term inhalation exposure of harmful substances mainly containing tobacco smoke, and is said to be a lifestyle-related disease that occurs in middle-aged or older people against the background of smoking habit.

In the drug therapy for COPD, a bronchodilator (an anticholinergic drug, a 2 -agonist, or a theophylline drug) is mainly used, and an inhaled anticholinergic drug or an inhaled 2 -agonist that mainly dilates the bronchi for a long time is used. In addition, an inhaled corticosteroid is used in severe cases.

In recent years, as a drug effective for the treatment of COPD, for example, a quinuclidine derivative as a muscarinic M 3 receptor antagonist (Patent Literature 1), N-phenylbenzamide having a bronchodilation effect (Patent Literature 2), and a substance that inhibits the production or accumulation of chondroitin sulfate proteoglycans as an emphysema inhibitor (Patent Literature 3), have been reported.

Test Example 1 (Human M 3 Receptor Antagonist Activity)

Measurement of the receptor binding ability was performed by using a transgenic human M 3 receptor expression CHO cell membrane, 1-[N-methyl- 3 H] scopolamine methyl bromide ([ 3 H]NMS, specific activity of 82 Cimmol). Protein concentration of the cell membrane was 2 g per well, concentration of the [ 3 H]NMS was 1.0 nM.

Range of the antagonist concentration (10 4 to 10 11 M) was tested by creating a comparison curve. Unspecific binding was measured in the presence of 1 M of atropine.

The reagent was adjusted to a total volume of 100 L with a binding buffer (phosphate buffer/saline). The mixture was incubated at room temperature for 2 hours so as to reach equilibrium, and then the resultant mixture was transplanted to a GF/C filter plate that had been pretreated with a washing buffer containing 0.05% polyethyleneimine for 1 hour.

The bound [ 3 H]NMS and the free[ 3 H]NMS were separated by rapid vacuum filtration, and washed three times with a rinse buffer (50 mM of Tris, 100 mM of saline, and pH of 7.4). The obtained filter was dried, and then onto the dried filter, a solid scintillator, MeltiLex A (manufactured by PerkinElmer, Inc.) was fused, and the measurement and quantification were performed by using a -counter (MicroBeta microplate scintillation counter (Trilux)).

The Ki value was calculated by the following equation. ([L]:[ 3 H]NMS concentration, Kd: dissociation constant of [ 3 H]NMS)

Ki=IC 50/(1+[ L]/Kd )

The Ki value (nM) of the obtained compound was shown in each Example.

Test Example 2 (Effect on Methacholine-Induced Airway Constriction)

Method

The increase of airway resistance by methacholine induction was measured. To 4 to 6-week old ICR mice, methacholine at 1 mg/mL was administered 5 times by spraying the methacholine for 20 seconds. After completion of the methacholine administration, the airway resistance was measured by a snap shot technique. All of the data were analyzed by using FlexiVent software.

The test compound at 47.9 g/kg was administered to the mice through the transairway. The mice were exposed 5 times to nebulized methacholine 1 hour, 96 hours, and 120 hours after the administration, and the airway resistance at each time was measured.

The results are shown in FIGS. 1 to 3.

Results

As can be seen from the results shown in FIGS. 1 to 3, the compound (1-18) and the compound (1-20) reduced the airway resistance at 47.9 g/kg even 120 hours after the administration. In contrast, as shown in FIG. 2, aclidinium did not reduce the airway resistance when exceeding 96 hours after the administration.
