Maximizing ISRIB Potential Requires Addressing Specificity, Long-term Safety, and Disease-specific Considerations

Area of Science:

• Biomedical research
• Pharmacology
• Cellular biology

Background:

• Integrated Stress Response Inhibitor (ISRIB) targets the integrated stress response pathway, affecting protein synthesis.
• Potential applications include neurological disorders, metabolic diseases, cognitive impairment, viral infections, and cancer.

Purpose of the Study:

• To review the challenges of ISRIB, focusing on specificity, long-term safety, and disease-specific considerations.
• To evaluate the therapeutic potential of ISRIB.

Main Methods:

• A narrative literature review was performed.
• The review examined ISRIB's chemistry, mechanisms of action, disease-specific factors, and long-term safety.

Main Results:

• ISRIB demonstrates promising preclinical results but requires further investigation for human safety and efficacy.
• Clinical trials are necessary to validate therapeutic potential, with recent discussions of trials lacking published data and raising concerns about side effects.

Conclusions:

• ISRIB presents significant potential for biomedical applications.
• Overcoming challenges in specificity, disease-specific application, and long-term safety is essential for ISRIB's clinical success.
