摘要:
在涉及核酸的大量应用中,带有硫醇基团的寡核苷酸是有用的中间体。本研究制备了携带叔丁基硫酰(t-BuS)保护硫醇基团的 DNA 寡核苷酸。我们开发了一种源自苏氨醇的构建模块,可在寡核苷酸的任何预定位置引入一个硫醇基团。所制备的硫醇化寡核苷酸已用于制备寡核苷酸共轭物,以及利用硫醇基团的反应活性对金纳米粒子进行功能化。

A method of preventing or inhibiting L-cystine crystallization using the compounds of formula (I) is disclosed, wherein A, L, R1a, R1b, and m are as described herein. The compounds may be prepared as pharmaceutical compositions, and may be used for the prevention and treatment of conditions that are causally related to L-cystine crystallization, such as comprising (but not limited to) kidney stones.
Oligonucleotides carrying thiol groups are useful intermediates for a remarkable number of applications involving nucleic acids. In this study, DNA oligonucleotides carrying tert-butylsulfanyl (t-BuS) protected thiol groups have been prepared. A building block derived from threoninol has been developed to introduce a thiol group at any predetemined position of an oligonucleotide. The resulting thiolated oligonucleotides have been used for the preparation of oligonucleotide conjugates and for the functionalization of gold nanoparticles using the reactivity of the thiol groups.
