Genetic Screens

5.8K
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...

Drug Discovery: Overview

12.3K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Area of Science:

  • Medicinal Chemistry
  • Drug Discovery
  • Chemical Biology

Background:

  • Identifying and prioritizing drug targets is crucial for new medicine discovery.
  • Existing methods for target identification and prioritization can be time-consuming and resource-intensive.

Purpose of the Study:

  • To develop and validate a novel method for rapid screening of multiple protein targets.
  • To assess the utility of DNA-encoded library technology (ELT) for evaluating protein ligandability.
  • To discover antibacterial leads and chemical series against challenging pathogens.

Main Methods:

  • Utilized DNA-encoded library technology (ELT) for parallel screening of proteins.
  • Screened 119 targets from Acinetobacter baumannii and Staphylococcus aureus.
  • Screened 42 targets from Mycobacterium tuberculosis.

Main Results:

  • Identified active chemical series for six targets from the initial screening.
  • Discovered three chemotypes for DHFR from Mycobacterium tuberculosis.
  • Demonstrated that parallel ELT selections can effectively assess protein ligandability.

Conclusions:

  • Parallel ELT selections offer a rapid and efficient approach to assess protein ligandability.
  • This method accelerates the discovery of potential drug leads and research tools.
  • Highlights opportunities for developing new therapeutics against bacterial infections.
