Definitions
- the present invention relates to a prophylactic and / or therapeutic agent for respiratory diseases, particularly an analgesic, comprising a 4-hydroxypiperidine derivative or a pharmaceutically acceptable salt thereof as an active ingredient.
- analgesic comprising a 4-hydroxypiperidine derivative or a pharmaceutically acceptable salt thereof as an active ingredient.
- the present invention provides a novel 4-hydroxypyridine derivative or a salt thereof, a method for producing the same, and a pharmaceutical composition comprising at least one of the derivatives as an active ingredient, particularly an agent for treating respiratory diseases, In particular, it relates to a cooling agent.
- Respiratory system is a general term for organs and tissues related to respiration, and plays an important role in sustaining life by taking in necessary oxygen and excreting carbon dioxide generated as a result of metabolism .
- typical diseases presenting with cough include lung ⁇ , cancerous lymphangiosis, rib fracture, spontaneous pneumothorax, cold syndrome, pulmonary tuberculosis, interstitial pneumonia, pleurisy, pneumonia, acute bronchitis, Examples include chronic bronchitis, emphysema, pneumoconiosis, bronchiectasis, diffuse panbronchiolitis, bronchial asthma, pulmonary embolism, pulmonary infarction, and the like.
- ⁇ refers to a phenomenon in which the lungs expand due to deep inhalation, the throat closes, and then the respiratory muscles strongly contract, increasing the pressure in the lungs, suddenly the laryngeal muscles relax, the throat opens, and air is rapidly exhaled. . At this time, secretions in the respiratory tract are exhaled. If secretions or foreign bodies accumulate in the respiratory tract mucous membrane, or if there is an abnormality in the pleura, lungs, diaphragm, etc., the stimulus from the ulcer reaches the central part of the posterior part of the medulla oblongata, causing reflex seizures. Science, 10.3 Antitussives, Sumiko Fujino, 1990, Kodansha).
- the main causes of cough are excessive secretion from the respiratory tract mucous membranes, chemical irritation such as smoke and gas, foreign bodies, inflammation of the respiratory tract, allergic reactions, compression of the bronchi due to intrathoracic tumors, psychogenicity, etc. is there.
- This exacerbation and chronicity of the cough results in the expenditure of respiratory muscle energy, depletion of physical strength, and impede the recovery of the underlying disease.
- antitussives There are two types of antitussives: centrally acting antitussives by blocking the central nervous system and peripherally antitussives that exert antitussively by reducing the stimulation of peripheral ⁇ receptors.
- Central antitussives represented by codin phosphate are generally sharp, but side effects include respiratory depression, constipation, nausea, vomiting, headache, drowsiness, and rash. It is also known that repeated use causes tolerance and dependence.
- Peripheral analgesics such as methylefedrine, can exert only mild analgesic effects.
- antagonists selective for opioid ⁇ receptors have been developed as analgesics.However, ⁇ receptors have been suggested to be deeply involved in mental and emotional behavior, and side effects have been suggested. There is concern (Natya Genetics, Vol. 25, No. 2, pp. 195, 2000). Therefore, antitussives that are more effective and have fewer side effects are needed.
- WO 02/22572 discloses a 3-substituted azetidine derivative, a 3-substituted pyrrolidine derivative, or a 3-substituted derivative having an action of regulating dopamine / seguchi tonin or norepinephrine receptor or transporter.
