Abstract

The frameshifting element (FSE) comprises a slippery heptanucleotide sequence followed by a downstream RNA structure, such as a pseudoknot or stem-loop. Found in various RNA viruses, FSE regulates viral replication via programmed -1 ribosomal frameshifting (-1 PRF), making it a potential broad-spectrum antiviral target. Advances in RNA structural analysis have elucidated the dynamic conformations and cross-viral diversity of FSE, with the SARS-CoV-2 outbreak further highlighting its role in viral replication. Efforts to develop antiviral drugs targeting FSE have progressed through virtual and phenotypic screening. In this review, we explore the evolution, structure, and function of FSE in coronaviruses, evaluate recent advances in FSE-targeted drug development, and discuss their design advantages, efficacy, and challenges, providing insights for future antiviral strategies.

冠状病毒中的移框元件:结构、功能和作为治疗靶点的潜力
移框元件(FSE)包括一个光滑的七核苷酸序列,随后是一个下游RNA结构,如假结或茎环。在多种RNA病毒中发现,FSE通过程序化-1核糖体移框(-1 PRF)调节病毒复制,使其成为潜在的广谱抗病毒靶点。RNA结构分析的进展已经阐明了FSE的动态构象和跨病毒多样性,SARS-CoV-2爆发进一步凸显了它在病毒复制中的作用。通过虚拟和表型筛选,开发针对FSE的抗病毒药物的努力取得了进展。在本文中,我们探讨了冠状病毒中FSE的进化、结构和功能,评估了FSE靶向药物开发的最新进展,并讨论了它们的设计优势、疗效和挑战,为未来的抗病毒策略提供见解。

期刊介绍: Trends in Pharmacological Sciences (TIPS) is a monthly peer-reviewed reviews journal that focuses on a wide range of topics in pharmacology, pharmacy, pharmaceutics, and toxicology. Launched in 1979, TIPS publishes concise articles discussing the latest advancements in pharmacology and therapeutics research. The journal encourages submissions that align with its core themes while also being open to articles on the biopharma regulatory landscape, science policy and regulation, and bioethics. Each issue of TIPS provides a platform for experts to share their insights and perspectives on the most exciting developments in the field. Through rigorous peer review, the journal ensures the quality and reliability of published articles. Authors are invited to contribute articles that contribute to the understanding of pharmacology and its applications in various domains. Whether it's exploring innovative drug therapies or discussing the ethical considerations of pharmaceutical research, TIPS provides a valuable resource for researchers, practitioners, and policymakers in the pharmacological sciences.
