Abstract: The series of quinoline derivatives were prepared. The synthetic procedures of compounds are presented. All the prepared derivatives were analyzed using the reversed phase high performance liquid chromatography (RP-HPLC) method for the lipophilicity measurement. In the present study the correlation between RP-HPLC retention parameter Log K (the logarithm of capacity factor K) and various calculated Log P data is shown. The prepared compounds were tested for their photosynthesis-inhibiting activity (the inhibition of photosynthetic electron transport in spinach chloroplasts (Spinacia oleracea L.) and the reduction of chlorophyll content in Chlorella vulgaris Beij.). Structure-activity relationships between the chemical structure and the biological activities of the evaluated compounds are discussed.
Keywords: quinoline derivatives; styrylquinoline analogues; photosynthesis inhibition; lipophilicity; structure-activity relationships; Chlorella vulgaris; spinach chloroplasts
