Definitions
- the present invention relates to a 1,8-naphthyridine derivative or a salt thereof. These substances are useful for prevention or treatment of diseases associated with ⁇ ⁇ ⁇ -type phosphodiesterase, particularly bronchial asthma.
- Asthma is a respiratory disorder that controls wheezing and seizures due to airway constriction.
- the number of patients has been steadily increasing, and is expected to increase further in the future.
- the predominant pathology of asthma is a) a sudden contraction of the smooth muscle surrounding the airways and b) an inflammatory response due to the activation of infiltrating cells in the respiratory tract, including the lungs. Therefore, it is considered that one of the effective means for asthma symptoms is to inhibit the contraction of airway smooth muscle and suppress or prevent the activation of infiltrating cells.
- xanthine skeleton such as aminophylline and theophylline
- PDE phosphodiesterase
- cAMP adenosine cyclic 3 ', 5'-monophosphate
- type IV PDEs specifically degrade cAMP without affecting guanosine cyclic 3 ', 5' monomonophosphate (cGMP) among nucleotides, Its presence has been observed in both infiltrating cells.
- cGMP guanosine cyclic 3 ', 5' monomonophosphate
- the intracellular cAMP concentration is determined by the balance between the rate of cAMP production by adenylate cyclase and the rate of cAMP degradation by PDE.
- intracellular cAMP levels can be increased by stimulating adenylate cyclase or inhibiting PDEs.
- Increased intracellular cAMP concentration causes suppression of contraction in airway smooth muscle and suppression of activation in inflammatory cells (Clin. Exp. Allergy 22 337-344 (1992), Drugs of the Futur) e J_7_ 799-807 (1 992)) 0
- Japanese Patent Application Laid-Open No. 55-164682 discloses 2-oxo-41-phenyl-1,5,7-trimethyl-2H-1,8-naphthyridine which has a diuretic effect, but type IV phosphodiesterase None has been disclosed about the anti-asthmatic effect associated with the selective suppression of the disease.
- WO 94/12499 Pamphlet (1994) discloses a compound having a phosphodiesterase inhibitory action and having the following general formula.
- the compounds of the present invention which are shown in a one-part formula below, are structurally different in that they have a ring-type substituent at the 4-position of the naphthyridine skeleton, and have a more excellent W-type phosphodiesterase inhibitory action. This is a remarkable difference.
- the compound of the present invention is expected to be an anti-asthmatic drug by selectively inhibiting type IV phosphodiesterase.
- type IV phosphodiesterase by inhibiting the contraction of airway smooth muscle and the activation of infiltrating cells, it suppresses not only the contraction of the airway that causes dyspnea, but also the inflammatory response that is considered to be the root of chronic asthmatic symptoms. It has a combination of properties and is less likely to exhibit the systemic effects exhibited by asthma therapeutics such as aminophylline (JPET 257 741-747 (1991)), so its safety and efficacy Is expected to be a high antiasthmatic drug.
