SUMMARY

Nucleosides, such as cytidine, uridine, adenosine, guanosine, thymidine, and inosine, are glycosylamines that play a crucial role in drug development, particularly in the treatment of HIV. These compounds can be phosphorylated by specific kinases to produce nucleotides, which are essential for DNA and RNA synthesis. Nucleoside analogs are incorporated into viral genetic material, disrupting reverse transcriptase synthesis, thereby leveraging the faster replication rates of viruses compared to human cells. While effective, these treatments can have side effects.

PREREQUISITES
  • Understanding of nucleoside and nucleotide structures
  • Knowledge of biochemical pathways involving kinases
  • Familiarity with reverse transcriptase and its role in HIV
  • Basic concepts of drug development and pharmacology
NEXT STEPS
  • Research the role of nucleoside analogs in antiviral therapies
  • Study the mechanisms of reverse transcriptase inhibitors
  • Explore the biochemical pathways of nucleotide biosynthesis
  • Investigate the side effects of nucleoside-based drugs in clinical applications
USEFUL FOR

This discussion is beneficial for pharmacologists, virologists, and researchers involved in drug development, particularly those focusing on antiviral therapies and the biochemical mechanisms of nucleosides.

The pathway of biosynthesis of nucleotide is commonly available in most textbook, but it is a bit difficult to find out that of nucleoside...

I know nucleoside can be useful drug, and it also exist in living body, but for what ?? for making nucleotide ?? or it form just by dissociation from nucleotide ??

Nucleosides are glycosylamines made by attaching a nitrogenous base to a ribose ring. Examples of these include cytidine, uridine, adenosine, guanosine, thymidine and inosine.

Nucleosides can be phosphorylated by specific kinases in the cell, producing nucleotides, which are the molecular building blocks of DNA and RNA.

Nucleoside triphosphates are the energy rich end products of the majority of biochemical energy releasing pathways.

Nucleoside use for drugs are analogous to those used by organisims. Therefore, the analogous nucleoside will be incorporate into the genetic material. These are mostly used in HIV treatment. These drugs interfere with the production of reverse transcriptase synthesis. The idea behind using these drugs is that viruses synthesis is faster than that of human and human have better error-repair mechanisms than retroviruses. Side effects exist.
