As a result during the synthesis and cleavage from the resin the tendency of PANAM with the N-terminal negatively charged monomer to cyclization with simultaneous N-acyl transfer of carboxyethyl base residue was found. Application of MALDI-TOF mass - spectrometry allowed us to find suitable conditions for obtaining PANAM oligomers without the significant amount of by-products.</p></abstract><trans-abstract xml:lang="ru"><p>Осуществлен твердофазный синтез тетрамерной модельной последовательности поли-амидных миметиков нуклеиновых кислот (ПАНКМ) с включением концевого хирального заряженного звена. Выявлена склонность ПАНКМ, содержащих N -концевой отрицательно заряженный мономер на основе L -глутаминовой кислоты, к циклизации с одновременным N -ацильным переносом карбоксиэтильного производного нуклеинового основания в ходе синтеза и отщепления со смолы. Использование MALDI - TOF -масс-спектрометрии в ходе эксперимента позволило найти подходящие условия отщепления олигомеров ПАНКМ, приводящие к существенному снижению количества побочных продуктов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиамидные миметики нуклеиновых кислот</kwd><kwd>пептидно-нуклеиновые кислоты (ПНК)</kwd><kwd>твердофазный синтез</kwd><kwd>MALDI-TOF-масс-спектрометрия</kwd><kwd>polyamide nucleic acid mimetics (PANAM)</kwd><kwd>peptide nucleic acids (PNA)</kwd><kwd>solid phase synthesis</kwd><kwd>MALDI-TOF mass-spectrometry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lebedeva I., Stein C.A.
