Complex of human dihydroorotate dehydrogenase with the inhibitor 221290
Structural highlights
DiseasePYRD_HUMAN Defects in DHODH are the cause of postaxial acrofacial dysostosis (POADS) [MIM:263750; also known as Miller syndrome. POADS is characterized by severe micrognathia, cleft lip and/or palate, hypoplasia or aplasia of the posterior elements of the limbs, coloboma of the eyelids and supernumerary nipples. POADS is a very rare disorder: only 2 multiplex families, each consisting of 2 affected siblings born to unaffected, nonconsanguineous parents, have been described among a total of around 30 reported cases.[1] FunctionPYRD_HUMAN Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor.

Publication Abstract from PubMedA strategy that combines virtual screening and structure-guided selection of fragments was used to identify three unexplored classes of human DHODH inhibitor compounds: 4-hydroxycoumarins, fenamic acids, and N-(alkylcarbonyl)anthranilic acids. Structure-guided selection of fragments targeting the inner subsite of the DHODH ubiquinone binding site made these findings possible with screening of fewer than 300 fragments in a DHODH assay. Fragments from the three inhibitor classes identified were subsequently chemically expanded to target an additional subsite of hydrophobic character. All three classes were found to exhibit distinct structure-activity relationships upon expansion. The novel N-(alkylcarbonyl)anthranilic acid class shows the most promising potency against human DHODH, with IC(50) values in the low nanomolar range. The structure of human DHODH in complex with an inhibitor of this class is presented.
