Genetic Screens

5.5K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Area of Science:

  • Medicinal Chemistry
  • Pharmacology
  • Biochemistry

Background:

  • Free-radicals are implicated in the pathogenesis of numerous diseases.
  • There is a continuous need for novel antioxidants to prevent radical-induced damage.
  • Complex diseases may involve free-radicals as significant, but not sole, drivers.

Purpose of the Study:

  • To explore the development of multipotent antioxidants with additional pharmacological effects.
  • To investigate strategies for obtaining antioxidants that can combat complex diseases.
  • To leverage nature's design principles for improved antioxidant development.

Main Methods:

  • Screening of drug collections and natural-product libraries for antioxidant compounds.
  • Coupling antioxidant moieties with other pharmacophores to create multifunctional molecules.
  • Analyzing the structural differences between rationally designed and naturally occurring antioxidants.

Main Results:

  • Multipotent antioxidants with diverse pharmacological actions are desirable for complex diseases.
  • Screening and chemical coupling are viable methods for generating novel antioxidants.
  • Nature's design strategies offer valuable insights for enhancing antioxidant design.

Conclusions:

  • Developing multipotent antioxidants is essential for addressing complex diseases.
  • Nature-inspired design approaches can lead to more effective antioxidant therapies.
  • Further research into nature's strategies can optimize the design of novel antioxidants.
