derivatives of nucleosides are most commonly used for further functionalization in the cross-coupling reaction because they are more reactive than bromine and chlorine. Previously, the synthesis of the N-Tr-protected morpholino nucleoside containing 1a was reported. The same authors published a procedure for the preparation of 40-N-Trand 20-OCH2-silyl protected morpholino nucleoside containing 5-iodocytosine
核苷的吗啉衍生物作为合成 DNA 或 siRNA 类似物的单体广泛用于医学和生物学。它们被认为是抗癌、抗病毒、抗菌和抗寄生虫治疗以及生物分析应用的有前途的药物。Morpholino 寡核苷酸是反义治疗中影响深远的候选者。Eteplirsen,吗啉代磷酸二酰胺寡核苷酸,于 2016 年被 FDA 批准用于治疗杜兴氏肌营养不良症。吗啉代核苷三磷酸似乎是 DNA 聚合酶 b 和 HIV-1 逆转录酶的底物,而吗啉代胸苷三磷酸被发现是 Taq DNA 聚合酶的底物. 使用杂环碱基处卤化的核苷衍生物为核苷、核苷酸、和寡核苷酸。核苷的碘衍生物最常用于交叉偶联反应中的进一步官能化,因为它们比溴和氯更具反应性。此前,已报道了含有 1a 的 N-Tr 保护的吗啉代核苷的合成。同一作者发表了一种制备含有 5-碘胞嘧啶作为杂环碱基的 40-N-Trand 20-OCH2-甲硅烷基保护的吗啉代核苷的程序。该方法包

as well as on the linkage between ADP and morpholino nucleoside. The 5-iodination of uracil and the introduction of the P–N bond in NAD+-mimetics have shown to increase inhibition properties. Structural modeling suggested that the P–N bond can stabilize the pyrophosphate group in active conformation due to the formation of an intramolecular hydrogen bond. The most active NAD+ analog against PARP-1 contained

Synthesis and cell transfection properties of guanidinium-functionalized uracil morpholino tetramer have been reported for the first time. Due to the basic nature of guanidinium groups they remain protonated under physiological conditions. Such cationic tetramer exhibits efficient cellular uptake properties as visualized by microscopy imaging using fluorescent dye BODIPY. 7'-End of this morpholino tetramer was functionalized with an azide group for conjugation with various types of biomolecules or drugs for cellular delivery.
