A method for the preparation of oligonucleotides containing the mutagenic base 4-O-ethylthymine is described for the first time. Use of p-nitrophenylethyl type base protecting groups together with phosphitetriester solid-phase methodology makes possible the rapid and efficient preparation of oligonucleotides bearing 4-O-ethylthymine, while standard base protecting groups are not compatible with the presence of this base. Possible applications of this methodology are discussed.
首次描述了一种制备含有诱变碱基4-O-乙基胸腺嘧啶的寡核苷酸的方法。对硝基苯乙基型碱基保护基团与亚磷酸三酯固相方法的使用使得快速有效地制备带有4-O-乙基胸腺嘧啶的寡核苷酸成为可能,而标准碱基保护基团与该碱基的存在不相容。讨论了该方法的可能应用。
