    After preincubation at 37 ° C for 3 hours, test compound
    added in the amount of 5000 h / min to B 16 melanoma cells growing as a monolayer in growth medium. The experiment was carried out three times. The mixture was then incubated at 37 ° C for 20 hours. After the growth medium was removed, the compounds for testing were washed and fresh growth medium was added. The number of cells was determined after 48 hours from the beginning of the incubation period with the microcellular Coulter Counter No. 1, which caused a 58% inhibition of cell growth in comparison with the experiment without the test compound.
    Thus, the compounds obtained inhibit the growth of tumor cells and have a higher acaricidal activity.
