1,4-Naphthoquinone
1,4-naphtoquinone, also known as 1,4-naphthalenedione or 1,4-dihydro-1,4-diketonaphthalene, is a member of the class of compounds known as naphthoquinones. Naphthoquinones are compounds containing a naphthohydroquinone moiety, which consists of a benzene ring linearly fused to a bezene-1,4-dione (quinone). 1,4-naphtoquinone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 1,4-naphtoquinone can be synthesized from naphthalene. 1,4-naphtoquinone is also a parent compound for other transformation products, including but not limited to, 2,3-dimethoxynaphthalene-1,4-dione, alisiaquinone A, and 1,4-naphthoquinone-2-carboxylic acid. 1,4-naphtoquinone can be found in liquor, which makes 1,4-naphtoquinone a potential biomarker for the consumption of this food product. 1,4-naphtoquinone is a non-carcinogenic (not listed by IARC) potentially toxic compound. CONFIDENCE standard compound; INTERNAL_ID 18 1,4-Naphthoquinone is a potential pharmacophore for inhibition of both MAO (monoamine oxidase) and DNA topoisomerase activities, this latter associated with antitumor activity[1].
Dihydroorotic acid
4,5-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). 4,5-Dihydroorotic acid is a substrate of the enzyme orotate reductase [EC 1.3.1.14], which is part of the pyrimidine metabolism pathway. (KEGG) Dihydroorotate is oxidized by Dihydroorotate dehydrogenases (DHODs) to orotate. These dehydrogenases use their FMN (flavin mononucleotide) prosthetic group to abstract a hydride equivalent from C6 to deprotonate C5 [HMDB] L-Dihydroorotic acid can reversibly hydrolyze to yield the acyclic L-ureidosuccinic acid by dihydrowhey enzyme[1].

1,4-Naphthoquinone
1,4-naphthoquinone appears as yellow needles or brownish green powder with an odor of benzoquinone. (NTP, 1992) 1,4-naphthoquinone is the parent structure of the family of 1,4-naphthoquinones, in which the oxo groups of the quinone moiety are at positions 1 and 4 of the naphthalene ring. Derivatives have pharmacological properties. It derives from a hydride of a naphthalene. 1,4-Naphthoquinone is a natural product found in Juglans nigra and Juglans regia with data available. 1,4-Naphthoquinone or para-naphthoquinone is an organic compound derived from naphthalene. Several isomeric naphthoquinones are known, notably 1,2-naphthoquinone. 1,4-Naphthoquinone forms volatile yellow triclinic crystals and has a sharp odor similar to benzoquinone. It is almost insoluble in cold water, slightly soluble in petroleum ether, and more soluble in polar organic solvents. In alkaline solutions it produces a reddish-brown color. Vitamin K is a derivative of 1,4-naphthoquinone. It is a planar molecule with one aromatic ring fused to a quinone subunit. Naphthalene is a constituent of jet fuel, diesel fuel and cigarette smoke. It is also a byproduct of incomplete combustion and hence is an ubiquitous environmental pollutant. The typical air concentration of naphthalene in cities is about 0.18 ppb. 1,4-Naphthoquinone is a potential pharmacophore for inhibition of both MAO (monoamine oxidase) and DNA topoisomerase activities, this latter associated with antitumor activity[1].
L-Dihydroorotic acid
L-Dihydroorotic acid, also known as (S)-4,5-dihydroorotate or dihydro-L-orotate, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. 4,5-Dihydroorotic acid is a derivative of orotic acid which serves as an intermediate in pyrimidine biosynthesis. L-Dihydroorotic acid is a drug. L-Dihydroorotic acid exists in all living species, ranging from bacteria to humans. Within humans, L-dihydroorotic acid participates in a number of enzymatic reactions. In particular, L-dihydroorotic acid can be biosynthesized from ureidosuccinic acid; which is catalyzed by the enzyme cad protein. In addition, L-dihydroorotic acid and quinone can be converted into orotic acid through the action of the enzyme dihydroorotate dehydrogenase (quinone), mitochondrial. In humans, L-dihydroorotic acid is involved in the metabolic disorder called the beta-ureidopropionase deficiency pathway. Outside of the human body, L-dihydroorotic acid has been detected, but not quantified in several different foods, such as black chokeberries, vanilla, sweet basils, soy beans, and broad beans. L-Dihydroorotic acid is an intermediate in the metabolism of Pyrimidine. It is a substrate for Dihydroorotate dehydrogenase (mitochondrial). [HMDB]. L-Dihydroorotic acid is found in many foods, some of which are lemon balm, eggplant, arrowhead, and european cranberry. L-Dihydroorotic acid can reversibly hydrolyze to yield the acyclic L-ureidosuccinic acid by dihydrowhey enzyme[1].
