Common Name4,5-Dihydroorotic acid
Description4,5-Dihydroorotic acid, also known as dihydroorotate or hydroorotate is a pyrimidinemonocarboxylic acid that results from the base-catalysed cyclisation of N-alpha-carbethoxyasparagine. It is classified as a secondary amide, a monocarboxylic acid, a pyrimidinemonocarboxylic acid and a N-acylurea. 4,5-Dihydroorotic acid is a derivative of orotic acid which serves as an intermediate in pyrimidine biosynthesis. 4,5-Dihydroorotic acid exists in all living species, ranging from bacteria to plants to humans. 4,5-Dihydroorotic acid is synthesized by the enzyme known as Dihydroorotase (EC 3.5.2.3) Which converts carbamoyl aspartic acid into 4,5-dihydroorotic acid as part of the de novo pyrimidine biosynthesis pathway (PMID: 13163076 ). 4,5-Dihydroorotic acid is also a substrate for the enzyme known as dihydroorotate dehydrogenase (DHODH). In mammalian species, DHODH catalyzes the fourth step in the de novo pyrimidine biosynthesis pathway, which involves the ubiquinone-mediated oxidation of dihydroorotate to orotate and the reduction of flavin mononucleotide (FMN) to dihydroflavin mononucleotide (FMNH2). Inhibition of DHODH activity with teriflunomide (an immunomodulatory drug) or expression with RNA interference results in reduced ROS generation and consequent apoptosis of transformed skin and prostate epithelial cells. Mutations in the DHOD gene have been shown to cause Miller syndrome, also known as Genee-Wiedemann syndrome, Wildervanck-Smith syndrome or post-axial acrofacial dystosis (PMID: 19915526 ).
