Abstract:
Tuberculosis (TB) is the deadliest bacterial disease in the world. New therapeutic agents are urgently needed to replace existing drugs for which resistance is a significant problem. DNA topoisomerases are well-validated targets for antimicrobial and anticancer chemotherapies. Although bacterial topoisomerase I has yet to be exploited as a target for clinical antibiotics, DNA gyrase has been extensively targeted, including the highly clinically successful fluoroquinolones, which have been utilized in TB therapy. Here, we review the exploitation of topoisomerases as antibacterial targets and summarize progress in developing new agents to target DNA topoisomerase I and DNA gyrase from Mycobacterium tuberculosis.
Insights
New drugs targeting DNA topoisomerases are crucial for combating tuberculosis (TB), a deadly bacterial disease. This review explores targeting DNA topoisomerase I and DNA gyrase in Mycobacterium tuberculosis.
Area of Science:
- Microbiology
- Molecular Biology
- Drug Discovery
Background:
- Tuberculosis (TB) remains a leading cause of bacterial death globally.
- Antimicrobial resistance necessitates novel therapeutic agents.
- DNA topoisomerases are validated targets for antimicrobial therapies.
Purpose of the Study:
- To review the use of topoisomerases as antibacterial targets.
- To summarize progress in developing new agents against Mycobacterium tuberculosis topoisomerases.
Main Methods:
- Literature review of topoisomerase as antibacterial targets.
- Summary of research on agents targeting DNA gyrase and topoisomerase I in M. tuberculosis.
Main Results:
- DNA gyrase is a well-established target, with fluoroquinolones being clinically successful.
- DNA topoisomerase I from M. tuberculosis is an underexplored but promising target.
- Progress is being made in developing novel agents for both targets.
Conclusions:
- Targeting DNA topoisomerases offers a viable strategy for new TB therapies.
- Further research into DNA topoisomerase I inhibitors is warranted.
- Developing new agents against M. tuberculosis topoisomerases is critical for overcoming drug resistance.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
