Abstract:
Small nucleic acid drugs including antisense oligonucleotides, small interfering RNAs, microRNAs, and aptamers, among others, have revolutionized the pharmaceutical industry in the 21st century, offering novel therapeutic strategies for a myriad of diseases through precise gene expression regulation or protein synthesis modulation. As of December 2024, 19 small nucleic acid drugs have been approved globally, with applications primarily in treating rare and hereditary conditions, metabolic diseases, and ophthalmological disorders, demonstrating great clinical potential. This review provides an overview of the classification, mechanism of action, technical challenges, and addressing strategies for small nucleic acid drugs, with a focus on the indications for market-available drugs, aiming to equip healthcare professionals with a thorough understanding and practical guidance on their utilization.

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
