Three new heterocyclic analogues (4-6) of dihydroorotic acid were designed, synthesized, and tested as inhibitors of dihydroorotase. Each compound possessed a tetrahedral sulfur atom at the position equivalent to carbon 4 in the dihydroorotate ring in an attempt to mimic the presumed tetrahedral transitionstate in the course of the enzymatic reaction. Additionally, N-carbamyl-3-phosphonoalanine was
