Area of Science:

  • Immunology
  • Pharmacology
  • Drug Discovery

Background:

  • Chemokines are crucial for immune cell migration and host defense.
  • Chemokine receptors, a type of G-protein-coupled receptor, are targets for inflammatory disease therapeutics.
  • Significant pharmaceutical investment is directed towards chemokine-based drug discovery.

Purpose of the Study:

  • To review in vitro assays used in identifying chemokine receptor antagonists.
  • To provide historical context of assay development in chemokine drug discovery.
  • To discuss clinical successes and failures of chemokine-targeted therapies.

Main Methods:

  • Literature review of in vitro assays for chemokine receptor antagonist screening.
  • Analysis of historical trends in drug discovery assays.
  • Examination of clinical trial outcomes for chemokine-targeting drugs.

Main Results:

  • Overview of various in vitro assay types employed at different discovery stages.
  • Examples illustrating the progression of drug candidates through the discovery pipeline.
  • Discussion of challenges and reasons for clinical trial failures.

Conclusions:

  • Targeting chemokine receptors remains a viable strategy despite past setbacks.
  • Future screening approaches may incorporate chemokine receptor dimerization.
  • Continued research is needed to overcome challenges in developing effective chemokine-based therapeutics.
