В ІЧ-спектрах наявні смуги поглинання, характерні для зв'язків C-H (аром.), C-H (аліф), C-O-C та NH протонованих термінальних аміногруп. У спектрах 1 H-ЯМР наявні сигнали від ароматич-них та аліфатичних протонів, мультиплетність та інтегральна інтенсивність яких відповідає припи-суваним структурам. На клітинах ПТП вивчена цитотоксичність низки 4,4'-біс-(2-аміноетокси)дифе-нілів, значення якої зіставні з токсичністю аміксину та знаходяться в діапазоні від низьких до помірних. SYNTHESIS AND CYTOTOXICITY OF AMINOETHOXYDIPHENYLS to induce IFI in biphenyl derivatives that are incapable to intercalate in NA indicates the possibility of implementing alternative mechanisms. This determined our interest to the study of aminoethoxydiphenyls (AED), which synthesis and investigation of cytotoxicity become the subject of this article. 4,4'-Bis-(2-chloroethoxy)diphenyl was obtained by alkylation of dihydroxydiphenyl with dichloroethane in its mixture with aqueous sodium hydroxide (20%) in the presence of tetrabutylammonium chloride (TBAC). Series of AED were synthesized by substitution of chlorine by iodine in the mixture of xylene with the aqueous solution of sodium iodide in the presence of TBAC with subsequent amination with primary and secondary amines. The protonated molecular ions (MI) intensive peaks of the compounds synthesized are observed in the mass spectra with FAB ionization. The most common way of MI fragmentation is
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
