DHODH-IN-13 is primarily utilized in the field of medical research and drug development. It functions as a potent inhibitor of the dihydroorotate dehydrogenase (DHODH) enzyme, which plays a critical role in the de novo pyrimidine biosynthesis pathway. By targeting this enzyme, DHODH-IN-13 is studied for its potential to suppress the proliferation of rapidly dividing cells, such as cancer cells or activated immune cells. This makes it a promising candidate for investigating treatments for malignancies, autoimmune diseases, and certain viral infections that rely on pyrimidine synthesis for replication. Additionally, its application extends to preclinical studies aimed at understanding the mechanisms of DHODH inhibition and its therapeutic implications.
