Oligonucleotide Therapeutics: New Analytical Tools And Applications

Oligonucleotide Therapeutics: New Analytical Tools And Applications Oligonucleotide oligonucleotides are short dna or rna molecules, oligomers, that have a wide range of applications in genetic testing, research, and forensics. An oligonucleotide is a short chain of nucleotides (nitrogen containing units linked to a sugar and a phosphate group) that consist of either single or double stranded dna or rna.

Oligonucleotide Therapeutics: New Analytical Tools And Applications

Oligonucleotide Therapeutics: New Analytical Tools And Applications The term oligonucleotide is derived from the greek “oligo,” which means few or small. the length of the oligonucleotide is usually denoted by the term “mer,”which is greek for “part.”. There have been 20 oligonucleotide drugs approved by the fda since 1998, and it's climbed to roughly two new drugs every year since 2016. such approvals range from antisense oligos (asos) to small interfering rnas (sirnas) to aptamers, reinforcing the multidisciplinary nature of this class of drugs. Following the first proof of concept of using small nucleic acids to modulate gene expression, a long period of maturation led, at the end of the last century, to the first marketing authorization of an oligonucleotide based therapy. The unique feature of components of nucleotides is how their structure influences the overall stability and functionality of the oligonucleotide. the presence of ribose or deoxyribose determines whether the oligonucleotide will serve as rna or dna, impacting its biological role.

The unique feature of components of nucleotides is how their structure influences the overall stability and functionality of the oligonucleotide. the presence of ribose or deoxyribose determines whether the oligonucleotide will serve as rna or dna, impacting its biological role. The structure of an oligonucleotide is similar to that of natural nucleic acids: it consists of a sugar phosphate backbone with attached nitrogenous bases (adenine, cytosine, guanine, thymine in dna, and uracil instead of thymine in rna). This review examines several oligonucleotide synthesis techniques, including phosphodiester, phosphotriester, and phosphoramidite approaches. it begins with a discussion of an early synthesis method involving a phosphoryl chloride intermediate, which proved unstable and prone to hydrolysis. Different classes of oligonucleotide therapeutics exist, referring to their mode of interaction with the target molecules. oligonucleotides binding to mrna rely on a watson crick base paring mechanism. To obtain the desired oligonucleotide, the building blocks are sequentially coupled to the growing oligonucleotide chain in the order required by the sequence of the product (see synthetic cycle below). the process has been fully automated since the late 1970s.
