Importance of new trends nucleosides

This analysis focuses on new developments in nucleoside biotechnology that have arisen in the recent decade.

A variety of variables are fuelling an ever-increasing interest in the research of this family of compounds:

(i) an increasing need for large-scale production of natural 2' -deoxy- -D-ribonucleosides, as well as analogs with carbohydrate and base fragment modifications, which may subsequently be utilized to synthesize and research oligonucleotides such as short interfering RNA (siRNA), microRNA (miRNA), and other oligonucleotides.

Nucleosides are a vast class of natural chemicals and chemically modified analogs with a wide range of structural characteristics.

The four 2′-deoxy—D-ribonucleosides of adenine (1) and guanine (2), as well as thymine (3) and cytosine (4), and the associated four -D-ribonucleosides (5-8), make up DNA and RNA, respectively (Scheme 1).

Analogs of these native nucleosides have been identified in RNA with variously changed carbohydrate and/or aglycon fragments and are also included in a sub-family of nucleoside antibiotics with a wide structural variety.

Phosphorylated nucleosides, commonly known as nucleotides, are key intermediates in the biosynthesis of DNA and RNA and co-substrates and cofactors in a variety of metabolic reactions.

New nucleobases are added to the genetic code regularly to meet specific scientific demands.

These synthetic nucleotides are employed to research DNA polymerase kinetics and sensitivity, and they have the potential to impede DNA polymerase activity.

With the increasing chemical variety of nucleotides available, issues on how different DNA polymerases use them may be addressed.

Much of the research in this field has focused on the A family DNA polymerases, such as Escherichia coli DNA polymerase, which are DNA polymerases that are engaged in replication and have a high fidelity, but more recent work has included other polymerases families, such as the Y family, whose members are known to be error-driven.
