    234 derivatives of 7-hydroxy-3-aryloxy-2-trifluoromethyl-4H-4-chromenones were synthesized and tested for antitumor activity in vitro against human cancer cell lines in NCI (National Cancer Institute, USA) bioassay. It was shown high cytostatic and cytotoxic activity for the tested compounds 1-8 (GI50 3.44-41.1 mM and LC50 from 49.6 mM). The relationship between structures of the tested compounds and their antiproliferative activities is discussed.Π‘ΠΈΠ½Ρ‚Π΅Π·ΠΎΠ²Π°Π½ΠΎ 234 ΠΏΠΎΡ…Ρ–Π΄Π½ΠΈΡ… 7-гідрокси-3-арилокси-2-Ρ‚Ρ€ΠΈΡ„Ρ‚ΠΎΡ€ΠΌΠ΅Ρ‚ΠΈΠ»-4Н-4-Ρ…Ρ€ΠΎΠΌΠ΅Π½ΠΎΠ½Ρƒ Ρ‚Π° дослідТСно Ρ—Ρ…Π½ΡŽ ΠΏΡ€ΠΎΡ‚ΠΈΡ€Π°ΠΊΠΎΠ²Ρƒ Π°ΠΊΒ­Ρ‚ΠΈΠ²Π½Ρ–ΡΡ‚ΡŒ Π½Π° лініях Ρ€Π°ΠΊΠΎΠ²ΠΈΡ… ΠΊΠ»Ρ–Ρ‚ΠΈΠ½ людини Ρƒ ΠΠ°Ρ†Ρ–ΠΎΠ½Π°Π»ΡŒΠ½ΠΎΠΌΡƒ Інституті Π Π°ΠΊΡƒ (БША).

    Automobile Media Discourse: Verbal Media Presentation of the Electric Cars

    No full text
    The article is devoted to a research of automobile media discourse. In the article lexical features of the English-speaking presentations of electric vehicles in mass media are distinguished. The concept "electric car / vehicle" is defined and the main ways of development of electric vehicles are considered. In the article advantages and shortcomings of electric cars in comparison with internal combustion engine vehicles in media presentations are disclosed. Structural and semantic features of the lexical presentation of electric vehicles in English-language media are revealed. The article demonstrates that the main lexical semantic, stylistic and grammatical features help the addresser in the media presentations of electrical cars to inform the addressee about goods, to form the positive image of the electric vehicles at the buyer and to induce to buy the electric car. The research contributes to the development of psycholinguistics, media linguistics, cultural linguistics, discourse theory and influence theory, automobile media linguistics on the example of verbal media presentations of electric cars / vehicals in English-speaking countries
