2. Description of the Related Art Pneumonia is an inflammation that occurs in the alveoli or lung interstitium. 1) Pneumonia due to microbial infection, 2) Allergic pneumonia, 3)
Lipoid pneumonia, 4) radioactive pneumonia, 5) chemical-induced pneumonia,

Pneumonia is most often caused by microorganisms, but pneumonia due to microbial infections has been decreasing due to recent improvements in treatment results with antibiotics and improved sanitary conditions. On the other hand, pneumonia caused by factors other than microorganisms (hereinafter abbreviated as non-infectious pneumonia) is less common than infectious pneumonia, but is often intractable, and if there is no effective therapeutic agent, There are many things. Only the adrenal steroid hormones that have been recognized as having a therapeutic effect are currently greatly restricted in application due to their strong side effects. Under such circumstances, a new preventive or therapeutic agent that is effective in treating these pneumonia and has few side effects is expected in medical practice.

Means for Solving the Problems The present inventors have conventionally proposed:
We have been investigating the mechanism and treatment of pneumonia, i.e., inflammation that occurs in the alveoli or interstitium. In the course of this research, ST638 and its derivatives, which are known to exhibit tyrosine kinase inhibitory activity, were used in rats. It has been found that the compound exhibits a therapeutic effect in an experimental pneumonia model such as a hypersensitivity pneumonia model and a paraquat pneumonia model. Based on the results, further studies have been made and the present invention has been completed.

Example 1 Wistar rats (male, 4-5 weeks old), an ovalbumin solution (1 mg / ml) dissolved in phosphate buffered saline (hereinafter abbreviated as PBS) and Freund's complete. 1 ml of an equal volume mixed oil emulsion of adjuvant (hereinafter abbreviated as FCA) was intraperitoneally administered, and after 3 weeks, the same booster immunization was performed.
500 mg of ovalbumin dissolved in ml was inhaled with an ultrasonic nebulizer for about 2 weeks to induce acute lung injury. 48 hours after inhalation, the rats were bled to death and the lungs were removed or washed to determine the degree of lung injury. The degree of lung injury was determined by gross findings and pathological observation of the removed lung and the degree of infiltration of inflammatory cells into the lung lavage fluid. Rats in the treatment group received S suspended in 0.2% Tween 80 solution one hour before inhalation.
T-638 was administered intraperitoneally at 100 mg / kg. The control group received the same volume of 0.2% Tween 80 solution as the treatment group.
The resected lung of the control group rats had a remarkable bleeding tendency, and the histopathological observation revealed a marked lesion. On the other hand, in the ST638 administration group, the bleeding tendency was clearly suppressed, and the tissue lesion was weak. In addition, when the number of inflammatory cells recovered in the lung lavage fluid was measured using a toma hemocytometer, the number of inflammatory cells was clearly reduced in the ST638 administration group as shown below.

The type and number of inflammatory cells recovered in the lung lavage were measured. The total cell count, neutrophil count, lymphocyte count and alveolar macrophage count collected in the lung lavage are shown in FIGS. In the figure, the control shows the normal group without antigen sensitization, the model shows the ovalbumin sensitization group, and ST638 shows the ST638 administration group. The antigen administration markedly increased the total cell count, neutrophil count, lymphocyte count and alveolar macrophage count recovered in the lung lavage fluid, and ST638 administration significantly suppressed these cell count increases.

Example 3 A group of 4 Wistar rats (male, 4-5 weeks old) was intraperitoneally administered with 30 mg / kg of paraquat, the lungs were removed on the 8th day, and observation of tissue lesions and lungs The number of cells in the washing solution was measured. Treatment groups included ST suspended in 0.2% Tween 80

Intraperitoneal administration was performed three times every hour, and the control group received the same volume of Tween 80. By administration of paraquat 30mg / kg, 8
By the day, 50% of the rats in both the control group and the ST638 administration group had died. When lung tissue lesions were compared for the surviving rats, diffuse changes were observed in almost all lungs in the control group, but the changes were clearly weak in the ST638-administered group.
The number of cells in the lung lavage fluid was also clearly reduced to (1.62 ± 0.11) × 10 6 cells compared to (4.42 ± 0.58) × 10 6 cells in the control group.
