Abstract
Przedmiotem wynalazku są nowe pochodne 3-podstawione-1-{2-[(4-nitrofenylo)amino]etylo}mocznika o wzorze ogólnym 1, gdzie R oznacza 1-naftyl, 4-acetylofenyl, 4-chlorobenzyl, 4-metoksybenzyl oraz nowe pochodne 3-podstawione-1-{2-[(5-nitropirydyn-2-ylo)amino]etylo}mocznika o wzorze ogólnym 2, gdzie R oznacza 1-naftyl, 3,4-dichlorofenyl, 4-acetylofenyl, 4-chlorobenzyl, metyl, 4-metoksybenzyl, 4-metoksyfenyl oraz sposób ich otrzymywania. Związki o wzorze ogólnym 1 oraz związki o wzorze ogólnym 2 otrzymuje się w reakcji odpowiednio podstawionymi izocyjanianami o wzorze ogólnym 3, gdzie R oznacza 1-naftyl, 4-acetylofenyl, 4-chlorobenzyl, 4-metoksybenzyl, 3,4-dichlorofenyl, 4-metoksyfenyl. Związek o wzorze ogólnym 2, gdzie R oznacza metyl otrzymuje się w reakcji z N-metylo-1H-imidazolo-1-karboksamidem z dodatkiem zasady organicznej. Reakcje prowadzi się w temperaturze pokojowej dobierając reagenty w stosunku molowym 1:1. Wydzielony osad oczyszcza się przez krystalizację z polarnego rozpuszczalnika, korzystnie z propan-2-olu, 1,4-dioksanu, kwasu octowego lub metodą chromatografii kolumnowej z użycie krzemionki i mieszaniny octanu etylu z heksanem. Ujawnione związki mogą znaleźć zastosowanie w leczeniu wybranych nowotworów.The present invention relates to new 3-substituted-1- {2 - [(4-nitrophenyl) amino] ethyl} urea derivatives of general formula 1, where R is 1-naphthyl, 4-acetylphenyl, 4-chlorobenzyl, 4-methoxybenzyl and new 3-substituted-1- {2 - [(5-nitropyridin-2-yl) amino] ethyl} urea derivatives of general formula 2 where R is 1-naphthyl, 3,4-dichlorophenyl, 4-acetylphenyl, 4-chlorobenzyl , methyl, 4-methoxybenzyl, 4-methoxyphenyl and the method of their preparation. Compounds of general formula 1 and compounds of general formula 2 are obtained by reacting appropriately substituted isocyanates of general formula 3, where R is 1-naphthyl, 4-acetylphenyl, 4-chlorobenzyl, 4-methoxybenzyl, 3,4-dichlorophenyl, 4- methoxyphenyl. The compound of general formula 2 where R is methyl is obtained by reaction with N-methyl-1H-imidazole-1-carboxamide with the addition of an organic base. The reactions are carried out at room temperature, selecting reagents in a 1: 1 molar ratio. The precipitate formed is purified by crystallization from a polar solvent, preferably propan-2-ol, 1,4-dioxane, acetic acid or by column chromatography using silica and a mixture of ethyl acetate and hexane. The disclosed compounds may find use in the treatment of selected cancers.
