Chemical Structures Of Antisense Oligonucleotides Mentioned In This ... The basic structure of an antisense oligonucleotide consists of a short chain of nucleosides linked by phosphodiester bonds. nucleosides include one base (adenine, cytosine, guanine, thymine, or uracil), a pentose sugar (deoxyribose or ribose), and a phosphate group. In this review, we systematically discuss the chemical modifications, mechanism of action, and optimized delivery strategies of several different classes of asos.

Key advancements include phosphorothioate oligonucleotides, pmo oligos, and gapmer antisense oligonucleotides, which improve clinical efficacy by increasing resistance to nuclease degradation. "antisense oligonucleotides are synthesized strands of dna, rna, or chemical analogs designed to bind to mrna produced by a disease causing gene, thereby inactivating it and turning the gene ""off.""". Antisense oligonucleotides (asos) are short (usually 15–25 nucleotides, nt), single stranded synthetic oligomers of nitrogenous bases that mimic dna or rna molecules. they can recognize specific messenger rna (mrna) molecules in a sequence dependent manner.

Figure 1 depicts a brief history of key discoveries, nucleic acid structure analysis, and breakthroughs in dna and rna synthesis as well as modification strategies on the way to fda approved oligonucleotide therapeutics. Antisense nucleic acids are independent of the cell cycle and can enter both proliferating and non proliferating cells. antisense oligonucleotides do not contain viral sequences, so they do not trigger immune responses or integrate into host chromosomes. To achieve his dream, we had to improve antisense oligonucleotide chemistry, understand how the chemistry, structure, and sequence influences antisense oligonucleotide function, and how the immune system deals with exogenous nucleic acids. The nuances of antisense oligonucleotide design are crucial for their functionality. through this exploration, we aim to elucidate the various strategies that underpin successful aso development, unpacking essential considerations such as sequence parameters and chemical modifications.
