A Review on Pyrazole Derivatives Used in the Treatment of Rheumatoid Arthritis: Recent Advancement and Drug Development

Abstract

Abstract: Rheumatoid arthritis (RA) is an autoimmune disorder where inflammation and destruc-tion of bone are the hallmarks of the disease. This review focuses on the etiology, pathophysiolo-gy, and treatment strategies for RA, along with the different approaches used for the synthesis of pyrazoles, the characterization of various properties, and their biological significance for curing RA. The activated immune system of the body causes inflammation of the synovial joint due to the interaction of immune cells, such as T and B lymphocytes, macrophages, plasma cells, den-dritic cells and mast cells. The treatment for RA has been revolutionized with the discovery of new chemical compounds and an understanding of their mechanism in the treatment of the dis-ease. Pyrazoles are the starting materials for the synthesis of heterocyclic compounds and possess great relevance in the pharmaceutical field for the development of new drugs. They are versatile bio-scaffolds in medicinal chemistry and organic synthesis. This has been followed by a deep analysis of pyrazoles and their derivatives on the basis of medical significance in the treatment of RA. This follow-up and information may help the chemists, scientists, and researchers to generate new pyrazole compounds with high efficacy for better treatment of patients with RA. We summa-rize the review with an understanding of the core of pyrazoles and a claim that their derivatives may be helpful in the development of efficient drugs against RA.
