The compounds of formula (I) are useful in the treatment of any conditions, including clinically .20 clinical ones, which are characterized by excessive secretion of B4 or D4 leukotrienes. These conditions include instant hypertension such as asthma. Evidence obtained over the past few years has shown the presence of leukotrienes in the saliva of patients with chronic bronchitis and cyst fibrosis. The presence of leukotrienes is the cause of these diseases. Moreover, a material has been found in rheumatic synovial fluid that reacts antigenically with LTD4 antibodies. This confirms the existence of leukotriene permeability factor, which together with LTBa increases the inflammatory process. The compounds of the invention should reduce some symptoms of chronic bronchitis and fibrosis of the cyst and probably rheumatoid arthritis due to their ability to: ™ counteract leukotrins. The term overexposure of leukotrins refers to the amount of leukotrins sufficient to cause a certain condition associated with such an amount. The amount of leukotrienes that is considered excessive depends on various factors, including the specific leukotrin, the amount of leukotrin needed to cause a certain condition, and the type of mammal. The effectiveness of the compound in reducing the connection of leukotriene B4 with human peripheral neutrophils. For this purpose, freshly prepared films of leukocytes in centrifuned blood from two individuals were obtained from the local donor center. Cells are mixed and diluted to 484 ml with phosphoric acid buffer salt containing heparin (10 units / ml) and calf blood serum inactivated by heat (5%). This was divided into 20 ml portions and servings deposited on the surface of the FP (12 ml). The material is then centrifuged to 500 g for 40 minutes at room temperature. The obtained top layer of platelets and mononuclear cells was removed. The lower layer containing red blood cells and neutrophils is left. A buffer solution (1 ml per 4 ml of the lower layer) was added and the suspension was mixed. For each 1 ml of this mixture, 0.33 ml of 6% MacRODex was added. After stirring, the cells were precipitated for 1 h at'37 ° C. The obtained erythrocyte pill was removed, and the pop-up liquid rich in neutrophils was centrifuged to 500 g for 10 min at 4 ° C. The erythrocyte cells still present in this pill were dissolved by keeping 5-8 ml of ice-cold distilled water for 30-45 s. Then the volume was adjusted to 50 ml by adding ice-cold buffer solution and resuspending the cells. The suspension was then centrifuged to 300 g for 10 min at 4 ° C. Finally, the cells were resuspended at a density of 2 x 10 7 cells / ml in the sample buffer solution. This solution contained a balanced saline solution of HaNKS and 0.1% ovalbumin (pH 7.3). This separation process resulted in> 90% neutrophil cell preparations and> 90% viability. The binder radioligand sample was carried out by incubation of neutrophils (1 x 10 7 cells) with 0.1-0.2 pm 3 K - 1_TVL (150-220 curie / mol) and the experimental compound (1 x 10 ' 5 M and 1 x 10 6 M) in for 10 min at 4 ° C. Then the number of bound STs - LTB4 was measured and compared with the number of bound ones without an experimental compound. The analysis was carried out in microcentrifuge tubes with the addition of 10 ml of the experimental compound first. dissolved in DMSO, followed by the addition of 20 ml of H - LTB4. diluted in test buffer. and finally, 500 ml of cell suspension was added. After 10 min incubation, 300 ml of a mixture of dibutyl phthalate and dinonil (7: 2) were added to the tubes, centrifuged for 2 min in a microcentrifuge. We measured the radioactive bond to the cell pill by scintillation spectroscopy. Corresponding corrections for nonspecific 3 H - LTB4 bonds were separated. '' The results of the experiments are shown in the table. As can be seen from the table, the compounds of formula (I) are superior in inhibitory effect to the binding of tritium-labeled leukotrin B4 to human peripheral neutrophils.
