Description Research Excerpts Clinical Trials Roles Classes Pathways Study Profile Bioassays Related Drugs Related Conditions Protein Interactions Research Growth

Diftalone is a synthetic steroid with anti-inflammatory and immunosuppressive properties. It has been studied for its potential therapeutic applications in various conditions, including rheumatoid arthritis, inflammatory bowel disease, and organ transplantation. Diftalone's mechanism of action involves inhibiting the production of inflammatory mediators, such as prostaglandins and leukotrienes, by blocking the activity of cyclooxygenase (COX) enzymes. It has also been shown to suppress the activity of T lymphocytes, key players in the immune response. However, diftalone's clinical use has been limited due to concerns regarding its potential side effects, including liver toxicity. Despite these challenges, ongoing research efforts are focused on developing safer and more effective diftalone analogs for therapeutic purposes.'
