| 中文摘要: |
| G-四链体是一类由Hoogsteen氢键维持稳定的，富含鸟嘌呤的DNA或RNA二级结构。人类基因组中存在大量潜在的形成G-四链体的序列，所形成的G-四链体结构能够调控基因组的稳定性、DNA复制和基因表达，其中包括很多与癌症相关基因。因此寻找能够诱导DNA的G富集区域形成G-四链体结构的配体，进而筛选潜在抗癌药物的先导化合物，已成为癌症治疗研究的热点之一。本文对近年来发现和设计的以G-四链体为靶点的小分子配体，按照靶向的G-四链体结构类型和配体的分子结构进行分类，综述了这类化合物在癌症治疗方面的研究进展，分析了相关靶向治疗存在的问题，并对未来的研究方向进行了展望。 |
| 英文摘要: |
| G-quadruplex is a kind of guanine-rich DNA or RNA secondary structures stabilized by the Hoogsteen hydrogen bonds. A large number of potential G-quadruplex formation motifs are present in the human genome, and the G-quadruplex structures regulate genomic stability, DNA replication, and gene expression, many of which are related to oncogenesis. Therefore, searching for ligands that can induce G-quadruplex formation in the guanine-rich regions of DNA and screening for potential compounds as anticancer drugs represent one of the research hotspots in the field of cancer therapies. This review summarized small molecule ligands that can target G-quadruplex structures. We classified these small molecule ligands based on the types of targeted G-quadruplexes and their molecular structures. We also reviewed the research progress of cancer therapies employing these compounds, discussed the existing issues of their applications, and prospected future research directions. |
