COX-2-IN-1 is primarily used in research settings to study the role of cyclooxygenase-2 (COX-2) enzymes in various biological processes. It serves as a selective inhibitor, helping scientists understand the enzyme's involvement in inflammation, pain, and certain diseases like cancer and arthritis. By blocking COX-2 activity, researchers can explore its impact on cellular pathways and develop potential therapeutic strategies. Additionally, it aids in distinguishing the effects of COX-2 from COX-1, providing insights into the development of safer anti-inflammatory drugs with fewer side effects.
