Thiouracil refers both to a specific molecule consisting of a sulfated uracil, and a family of molecules based upon that structure.

Medical use[edit]

The substance is a historically relevant anti-thyroid preparation. Astwood E.B. used it in 1943 as therapy of Graves' disease for the first time.[1] It remains in use.

Thiouracil inhibits thyroid activity by blocking the enzyme thyroid peroxidase.[2]
