Biosynthesis of Nucleic Acids

2
Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...

Area of Science:

  • Virology
  • Drug Discovery
  • Molecular Biology

Background:

  • Recent monkeypox (mpox) outbreaks present a new public health challenge.
  • Specific antiviral treatments for mpox are limited, necessitating drug repurposing strategies.
  • Existing antivirals like Tecovirimat may be used, but targeted therapies are needed.

Purpose of the Study:

  • To review nucleoside analogues as potential antiviral agents against mpox.
  • To highlight the importance of viral polymerase structural specificity in drug selection.
  • To provide a framework for developing targeted antiviral therapies.

Main Methods:

  • Focus on nucleoside analogues targeting viral DNA-dependent DNA polymerase.
  • Comparison of DNA-dependent DNA polymerases with other viral polymerases.
  • Analysis of structural features influencing nucleoside analogue efficacy and selectivity.

Main Results:

  • Nucleoside analogues are promising candidates for mpox antiviral therapy.
  • Structural specificity of viral polymerases is crucial for rational drug design.
  • Understanding polymerase structure aids in preselection and optimization of nucleoside analogues.

Conclusions:

  • Targeted development of nucleoside analogues can accelerate mpox antiviral therapy.
  • Structural insights into viral polymerases are essential for effective drug repurposing.
  • This approach can benefit the development of therapies for other viral infections.
