[https://www.uniprot.org/uniprot/PYRD_HUMAN PYRD_HUMAN] Defects in DHODH are the cause of postaxial acrofacial dysostosis (POADS) [MIM:[https://omim.org/entry/263750 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.<ref>PMID:19915526</ref>

== Publication Abstract from PubMed ==
 +
Pyrimidine biosynthesis is an attractive drug target in a variety of organisms, including humans and the malaria parasite Plasmodium falciparum. Dihydroorotate dehydrogenase, an enzyme catalyzing the only redox reaction of the pyrimidine biosynthesis pathway, is a well-characterized target for chemotherapeutical intervention. In this study, we have applied SPROUT-LeadOpt, a software package for structure-based drug discovery and lead optimization, to improve the binding of the active metabolite of the anti-inflammatory drug leflunomide to the target cavities of the P. falciparum and human dihydroorotate dehydrogenases. Following synthesis of a library of compounds based upon the SPROUT-optimized molecular scaffolds, a series of inhibitors generally showing good inhibitory activity was obtained, in keeping with the SPROUT-LeadOpt predictions. Furthermore, cocrystal structures of five of these SPROUT-designed inhibitors bound in the ubiquinone binding cavity of the human dihydroorotate dehydrogenase are also analyzed.
