Some new derivatives of Ni(II) with uracil, uridine and nucleotides
Inorganica Chimica Acta, 1986AbstractThe Ni(II) complexes (I)‐(V) are prepared from Ni(II) acetate or Ni(en)2Cl2 by 1:1 or 1:2 molar reaction with uracil, uridine, or the disodium salts of the appropriate nucleotides.

Proton magnetic resonance data for uridine and uridine-5′-monophosphate, and the corresponding 6-azauracil analogs, are presented and discussed in terms of their overall three dimensional conformations in aqueous solution. The data reveal a destabilizing influence of the 6-aza base upon the gog and g′–g′ conformation of the ribose phosphate moiety.

Potential signalling roles for UTP and UDP: sources, regulation and release of uracil nucleotides
Trends in Pharmacological Sciences, 1997Increasing evidence for receptors for uracil nucleotides has focused interest on specific signalling mechanisms involving UTP and UDP. At least three metabotropic P2 receptors are stimulated by uracil nucleotides with equal or greater potency than by adenine nucleotides, and there might be ionotropic receptors as well.

AbstractStarting with the complexes trans‐(Co(en)2Cl2)Cl and (Co(NH3)5Cl)Cl2 the reaction with uracil and uridine in ethylacetate under reflux and with the sodium salts of the nucleotides yields the compounds (I)‐(IV), respectively (no yields given).

Titania-based photocatalytic degradation of two nucleotide bases, cytosine and uracil
Applied Catalysis A: General, 2014Abstract The photocatalytic degradation of two components of DNA and RNA, cytosine (C4H5N3O) and uracil (C4H4N2O2) differing only by the presence of an amine or a carbonyl group was investigated in the presence of UV-irradiated TiO2 aqueous suspensions.

Concentration of uracil nucleotides and UDP-glucose in mouse liver after partial hepatectomy
International Journal of Biochemistry, 1978Abstract 1. 1. The UTP and UDP concentration of mouse liver was not significantly affected by the partial hepatectomy, whereas the size of the UMP pool increased 3- to 4-fold when compared to unoperated controls. 2. 2. In regenerating liver, the UDP-glucose concentration decreased by 20% or more when compared to unoperated controls. 3. 3.

The turnover of cardiac adenine and uracil nucleotides was studied in the hypertrophying rat heart by means of the kinetics of incorporation of labeled phosphate into the alpha-phosphate groups of nucleotides. Cardiac hypertrophy was induced either by chronic isoproterenol treatment (5 mg X kg-1 body wt. daily, s.c.) or by abdominal aortic constriction.
