Drug Discovery: Overview

10.2K
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...

Pulmonary Tuberculosis V

287
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Area of Science:

  • Microbiology and Infectious Diseases
  • Drug Discovery and Development

Background:

  • Tuberculosis (TB), caused by *Mycobacterium tuberculosis*, remains a global health challenge.
  • Existing treatments face limitations due to drug resistance, long duration, and toxicity.
  • There is an urgent need for novel anti-tubercular agents.

Purpose of the Study:

  • To review traditional and innovative techniques for discovering new anti-tubercular compounds.
  • To highlight advancements enabling the discovery of hits and leads with known targets and whole-cell activity.
  • To discuss strategies for overcoming challenges in mycobacterial drug discovery.

Main Methods:

  • Exploration of target-to-drug approaches (biochemical assays, computational screens).
  • Examination of drug-to-target approaches (screening compound libraries for whole-cell activity).
  • Discussion of integrated approaches combining aspects of both traditional methods.

Main Results:

  • Target-to-drug approaches have shown limited success in yielding clinical candidates due to lack of whole-cell activity.
  • Drug-to-target approaches ensure whole-cell activity but face challenges in target identification.
  • Advances in science facilitate the development of novel tools that integrate both approaches.

Conclusions:

  • Novel drug discovery tools are emerging to accelerate the identification of anti-TB compounds.
  • These tools aim to yield hits and leads with both known targets and demonstrated whole-cell activity.
  • The review provides insights into current and future strategies for combating TB drug resistance.
