About Pyrimidine Synthesis Inhibitors.

Pyrimidine synthesis inhibitors are an established pharmacologic class of immunomodulatory agents that block de novo pyrimidine nucleotide production.

They exert their therapeutic effect primarily by inhibiting dihydroorotate dehydrogenase, a key mitochondrial enzyme essential for generating the pyrimidines required for DNA and RNA synthesis in rapidly proliferating cells.

By arresting lymphocytes in the G1 phase and reducing active T- and B-cell proliferation, these agents suppress targeted immune-mediated inflammatory cascades.

In clinical practice, members of this class—most notably leflunomide and teriflunomide—are primarily indicated for the management of autoimmune disorders, specifically active rheumatoid arthritis and relapsing forms of multiple sclerosis.
