Progress and challenges of selective Farnesoid X Receptor modulation

Area of Science:

• Endocrinology and Metabolism
• Molecular Biology
• Pharmacology

Background:

• Bile acids are key signaling molecules regulating metabolism and inflammation via the farnesoid X receptor (FXR).
• FXR activation influences bile acid, lipid, glucose, and amino acid metabolism, and also limits inflammatory responses.
• FXR is a therapeutic target for metabolic and inflammatory diseases like obesity, NASH, and cholestasis.

Purpose of the Study:

• To review the rationale for developing selective FXR modulators (SBARMs).
• To discuss strategies for dissociating metabolic and inflammatory signaling pathways.
• To explore gene- and tissue-specific targeting for improved therapeutic outcomes.

Main Methods:

• Review of existing literature on bile acid signaling and FXR.
• Analysis of strategies for designing selective nuclear receptor modulators.
• Discussion of structural mechanisms underlying ligand-receptor interactions.

Main Results:

• Current FXR agonists often lack specificity, leading to potential side effects.
• SBARMs aim to separate beneficial metabolic effects from inflammatory modulation.
• Development focuses on achieving gene- and tissue-specific FXR activation.

Conclusions:

• Selective FXR modulators offer a promising therapeutic approach for metabolic and inflammatory diseases.
• Dissociating FXR signaling pathways is key to minimizing adverse effects.
• Further research into SBARM design and pharmacology is warranted.
