Abstract
1.Производные олигонуклеотидов, содержащие одну или более фосфорамидных групп, соответствующих общей формуле (I):(I)где заместители R и Rнезависимо являются остатками нуклеозидов или модифицированных нуклеозидов, в том числе входящих в состав олигонуклеотида, либо один из них является остатком нуклеозида или олигонуклеотида, а другой является линкером к полимерному носителю, органическим радикалом или атомом водорода;Rявляется атомом водорода Н или органическим радикалом.2.Производное олигонуклеотидов по п. 1, отличающееся тем, что органический радикал Rвыбирается из группы, содержащей в том числе алкилазидную группу, соответствующие защитные группы, ацильную группу -СОR, алкоксикарбонильную группу -СООR, в том числе 9-флуоренилметоксикарбонильную группу (Fmoc), и карбамоильную группу -СОNRR, где Rи Rмогут быть независимо атомом водорода или органическим радикалом, в том числе защитной группой.3. Способ получения производных олигонуклеотидов по п. 1, включающий взаимодействие фосфита (II) с азидом RNпри температуре в диапазоне от -20С до 150С в течение периода времени от 1 мин до 24 ч до превращения указанного фосфита (II) в соответствующее защищенное производное олигонуклеотида по п. 1, и последующее удаление защитных групп с получением незащищенного модифицированного олигонуклеотида, содержащего одну или более фосфорамидных групп (I)(II)4. Способ по п. 3, отличающийся тем, что проводится выделение и очистка полученного модифицированного нуклеотида или олигонуклеотида при помощи обычных хроматографических или электрофоретических методов выделения и очистки нуклеотидов или олигонуклеотидов.5. Способ по п. 3 или 4, отличающийс1. Derivatives of oligonucleotides containing one or more phosphoramide groups corresponding to the general formula (I) :( I) where the substituents R and R are independently nucleoside or modified nucleoside residues, including those included in the oligonucleotide, or one of them is a nucleoside residue or oligonucleotide, and the other is a linker to a polymer carrier, an organic radical or a hydrogen atom; R is a hydrogen atom H or an organic radical. 2. The oligonucleotide derivative according to claim 1, characterized in that The radical R is selected from the group consisting of, among other things, the alkyl azide group, the corresponding protecting groups, the acyl group -COR, the alkoxycarbonyl group -COOR, including the 9-fluorenylmethoxycarbonyl group (Fmoc), and the carbamoyl group -CONRR, where R and R can independently be an atom hydrogen or an organic radical, including a protecting group. 3. A method for producing oligonucleotide derivatives according to claim 1, comprising reacting phosphite (II) with RN azide at a temperature in the range of -20 ° C to 150 ° C for a period of 1 minute to 24 hours before converting said phosphite (II) into the corresponding protected oligonucleotide derivative according to claim 1 . 1, and the subsequent removal of the protective groups to obtain an unprotected modified oligonucleotide containing one or more phosphoramide groups (I) (II) 4. The method according to claim 3, characterized in that the isolation and purification of the obtained modified nucleotide or oligonucleotide is carried out using conventional chromatographic or electrophoretic methods for the isolation and purification of nucleotides or oligonucleotides. A method according to claim 3 or 4, characterized in
