CXCR2 receptor antagonists: a medicinal chemistry perspective

Area of Science:

• Medicinal Chemistry
• Pharmacology
• Immunology

Background:

• Dysregulated leukocyte recruitment drives acute and chronic inflammatory diseases.
• Chemokines like CXCL8 and CXCL1 are crucial for directing leukocytes to inflammation sites.
• CXCR2 receptor antagonists are attractive therapeutic targets for inflammatory conditions.

Purpose of the Study:

• To review medicinal chemistry efforts in identifying CXCR2 receptor antagonists over the past 15 years.
• To focus on structure-activity relationships, pharmacology, and preclinical in vivo evaluations.
• To discuss clinical data of advanced CXCR2 antagonist compounds and future perspectives.

Main Methods:

• Literature review of medicinal chemistry research on CXCR2 antagonists.
• Analysis of structure-activity relationships (SAR) for various antagonist classes.
• Evaluation of preclinical pharmacology and in vivo data for identified compounds.

Main Results:

• Over a dozen distinct classes of CXCR2 receptor antagonists have been developed.
• Several compounds have progressed to mid-stage clinical trials.
• Extensive preclinical data exists for various series of CXCR2 antagonists.

Conclusions:

• Significant medicinal chemistry progress has been made in developing CXCR2 antagonists.
• The CXCR2 pathway remains a key target for novel anti-inflammatory therapies.
• Further clinical evaluation is essential for advancing these compounds.
