1. Introduction to DHODH Inhibitors and Their Therapeutic Relevance
Dihydroorotate dehydrogenase (DHODH) is an enzyme integral to pyrimidine biosynthesis, crucial for lymphocyte proliferation. Inhibition of DHODH suppresses immune responses, making these agents potent for autoimmune diseases such as rheumatoid arthritis (RA), multiple sclerosis (MS), and Crohn’s disease (CD). The therapeutic rationale hinges on selective immune modulation with minimal systemic toxicity.
