    摘要:
    瓜德西他滨 (SGI-110) 是一种二核苷酸,是地西他滨的前药。该二核苷酸包含地西他滨(顶部片段)和 2'-脱氧鸟苷(9;dG;底部片段)通过 3' → 5' 磷酸二酯键连接。瓜地西他滨的制造过程需要大量的 N 2 , 3'-O-(4-叔丁基苯氧基乙酰基)-保护的 dG (2; Bis-Tac-dG) 以掺入底部片段。受保护的2是二核苷酸的关键起始材料,对其合成和分离提出了严格的质量要求。本文介绍的是从商业 dG 开始的化合物 2 的实用且可扩展的路线的开发工作。该方法的显着特点包括用 4,4'-二甲氧基三苯甲基 (DMT) 基团以及随后的 3'-O- 对 N 2 -Tac-dG (3) 的 5'-OH 基团进行一锅保护。 Tac 保护为 dG 8 提供全面保护,从而通过更少的分离步骤缩短循环时间并降低溶剂使用量。随后,利用 NaIO 4 从 8 中裂解 DMT 基团,实现了温和、高选择性和稳健的路线,以公斤级生产高纯度

  • PROCESS FOR THE SYNTHESIS OF OLIGONUCLEOTIDES
    申请人:Leuck Michael
    公开号:US20080064867A1
    公开(公告)日:2008-03-13
    The present invention discloses novel methods for the synthesis of oligonucleotides with nucleoside phosphoramidites on solid supports. The methods comprise the stepwise chain assembly of oligonucleotides on supports with 5′-acyl phosphoramidites. The synthesis cycles consist of a front end deprotection step which is conducted with a solution of a primary amine or a phenolate, a phosphoramidite coupling step with a 5′-acyl nucleoside phosphoramidite in the presence of an activator, a phosphite oxidation step and an optional capping step. The novel methods improve the quality of synthetic oligonucleotides due to the irreversibility of the front end deprotection step, which prevents the formation of deletion sequences, and due to the avoidance of acidic reagents in the synthesis cycles, which prevent the formation of depurination side products. The invention further discloses novel nucleoside phosphoramidite compositions wherein the phosphoramidites carry acyl front end protective groups which are cleavable with primary amines or phenolates. The invention is applicable to the synthesis of oligodeoxyribonucleotides, oligoribonucleotides and oligonucleotides with modifications in their sugar or phosphate groups.
    本发明揭示了一种新的方法,用于在固相支持上合成具有核苷酸磷酰胺酯的寡核苷酸。该方法包括使用5'-酰基磷酰胺酯在支持上逐步组装寡核苷酸链。合成周期包括前端去保护步骤,该步骤使用一种原始胺或酚酸溶液进行,磷酰胺酯偶联步骤使用5'-酰基核苷酸磷酰胺酯在活化剂存在下进行,磷酸酯氧化步骤和可选的帽子步骤。由于前端去保护步骤的不可逆性防止了缺失序列的形成,而避免使用酸性试剂在合成周期中防止了去噻嗪副产物的形成,因此,这种新方法提高了合成寡核苷酸的质量。本发明进一步揭示了新的核苷酸磷酰胺酯组合物,其中磷酰胺酯携带可用原始胺或酚酸裂解的酰基前端保护基团。该发明适用于合成具有糖或磷酸基团修饰的寡脱氧核苷酸,寡核糖核苷酸和寡核苷酸。

  • Process Development of Biocatalytic Regioselective 5′-<i>O</i>-Levulinylation of 2′-Deoxynucleosides
    作者:Alejandro Carnero、Yogesh S. Sanghvi、Vicente Gotor、Susana Fernández、Miguel Ferrero
    DOI:10.1021/acs.oprd.5b00152
    日期:2015.7.17
    An enzymatic process was optimized for regioselective levulinylation of the S'-hydroxyl group in 2'-deoxynucleosides. The results revealed that the nucleobase protecting group influenced the successful outcome of the enzymatic reaction. The enhanced solubility of 4-tert-butylphenoxyacetyl protected 2'-deoxynucleoside played a major role during acylation reaction enabling the starting nucleosides to be the best substrates for Candida antarctica lipase B. Furthermore, we have developed a packed column protocol as a superior alternative to batch process carried-out in a flask, particularly when scale-up is required. The industrial application of this method was demonstrated via the synthesis of 5'-O-levulinylthymidine on a 25 g scale.
