Tenidap is a synthetic organic compound and dual inhibitor of cyclooxygenase (COX) and 5-lipoxygenase (LOX) enzymes, primarily used as a research reagent in pharmaceutical studies on rheumatoid arthritis due to its anti-inflammatory and analgesic properties. It inhibits the biosynthesis of prostaglandins and leukotrienes, key mediators of inflammation and pain, making it effective in experimental models for reducing joint swelling, stiffness, and discomfort. It has also been investigated for osteoarthritis and ankylosing spondylitis. Typically supplied as a high-purity solid (≥98%) for laboratory use. Note: For research purposes only; not intended for human or veterinary therapeutic use. Clinical development was limited due to potential hepatotoxicity.
