Dihydroorotate dehydrogenase (DHODH) is the fourth enzyme in the de novo pyrimidine biosynthesis pathway, serving as the catalyst to oxidize the dihydroorotate to orotic acid in the biosynthesis of uridine monophosphate (UMP). DHODH is a known target for autoimmune diseases as well as an important target for malaria.

Based on localization and electron acceptor, DHODHs have classified into two families: Family 1 members are soluble proteins localized to the cytosol, while family 2 members are membrane proteins localized to the inner mitochondrial membrane. Family 1 is further subdivided into family 1A and family 1B, which use fumarate and NAD+ (respectively) as electron acceptors. Family 2 DHODH enzymes use respiratory quinones as electron acceptors.

    BRD7539
    		Inhibitor
    BRD7539 is a PfDHODH inhibitor (IC50 = 0.033 μM). BRD7539 has potent activity against both multidrug-resistant asexual blood-stage (P. falciparum, Dd2 strain, EC50 = 0.010 μM) and liver-stage (P. berghei, EC50 = 0.015 μM) parasites.

    Redoxal
    		Inhibitor
    Redoxal is a dihydroorotate dehydrogenase (DHODH) inhibitor and anti-HIV-1 agent. Redoxal induces intracellular pyrimidine depletion by inhibiting the de novo pyrimidine biosynthesis pathway, enhances the protein stability of APOBEC3G (A3G), upregulates the abundance of A3G protein in cells and progeny viral particles, thereby strengthening the host endogenous antiviral restriction mediated by A3G. Redoxal selectively targets DHOdehase at the mitochondrial level, with an IC50 of 430 nM for inhibiting DHO oxidation in human mitochondria and an IC50 of 910 nM in rat mitochondria. Redoxal can be used in studies related to HIV-1 infection.
