A Lactobacillus plantarum fermentation product (Bio21B), obtained after strain growth (14h) in a wheat flour-based medium, was applied in the bread-making process as taste enhancer, in order to obtain a yeast-leavened bread with reduced salt content (20% and 50%) with respect to a reference bread (REF) not containing the fermentation product. Sensory analysis indicated that the Bio21B bread with salt reduced by 50% had a pleasant taste similar to the salt-containing bread (REF). l-Glutamate and total free amino acid content did not differ between REF and Bio21B breads, while the acids lactic, acetic, phenyllactic, 4-OH-phenyllactic and indole-3-lactic were present only in Bio21B breads...

5'-nucleotidases (EC catalyze the hydrolytic dephosphorylation of 5'-ribonucleotides and 5'-deoxyribonucleotides as well as complex nucleotides, such as uridine 5'-diphosphoglucose (UDP-glucose), nicotinamide adenine dinucleotide and flavin adenine dinucleotide, to their corresponding nucleosides plus phosphate. These enzymes have been found in diverse species in intracellular and membrane-bound, surface-localized forms. Soluble forms of 5'-nucleotidases belong to the ubiquitous haloacid dehalogenase superfamily (HADSF) and have been shown to be involved in the regulation of nucleotide, nucleoside and nicotinamide adenine dinucleotide (NAD+) pools...

After decades of intensive research on adenosine-3',5'-cyclic monophosphate (cAMP)- and guanosine-3',5'-cyclic monophosphate (cGMP)-related second messenger systems, also the noncanonical congeners cyclic cytidine-3',5'-monophosphate (cCMP) and cyclic uridine-3',5'-monophosphate (cUMP) gained more and more interest. Until the late 1980s, only a small number of cCMP and cUMP analogs with sometimes undefined purities had been described. Moreover, most of these compounds had been rather synthesized as precursors of antitumor and antiviral nucleoside-5'-monophosphates and hence had not been tested for any second messenger activity...

Lithocholic acid (LCA) deposited in human livers always induces drastic pains which need analgesic drug, like morphine to release. Our research showed that LCA can effectively inhibit uridine 5'-diphospho-glucuronosyltransferase 2B7 (UGT2B7) in morphine tolerance-like human normal liver cells, HL-7702, then increase μ-opioid receptor (MOR) and calcium-calmodulin dependent protein kinase IIα (CaMKIIα) expression. In vivo assay, UGT2B7 was significantly repressed in the livers of acute or chronic morphine tolerance mice pretreated with LCA (10, 50, and 100 mg/kg, p...

Zr(IV) can form phosphate and Zr(IV) (-PO₃(2-)-Zr(4+)-) complex owing to the high affinity between Zr(IV) with phosphate. Zr(IV) can induce the aggregation of gold nanoparticles (AuNPs), while adenosine triphosphate(ATP) can prevent Zr(IV)-induced aggregation of AuNPs. Herein, a visual and plasmon resonance absorption (PRA)sensor for ATP have been developed using AuNPs based on the high affinity between Zr(IV)with ATP. AuNPs get aggregated in the presence of certain concentrations of Zr(IV). After the addition of ATP, ATP reacts with Zr(IV) and prevents AuNPs from aggregation, enabling the detection of ATP...

Folates have been used with cytotoxic agents for decades and today they are used in hundreds of thousands of patients annually. Folate metabolism is complex. In the treatment of cancer with 5-fluorouracil, the administration of folates mechanistically leads to the formation of [6R]-5,10-methylene-tetrahydrofolate, and the increased concentration of this molecule leads to stabilization of the ternary complex comprising thymidylate synthase, 2'-deoxy-uridine-5'-monophosphate, and [6R]-5,10-methylene-tetrahydrofolate...

This study reports a new methodology to synthesize exo-glycals bearing both a sulfone and a phosphonate. This synthetic strategy provides a way to generate exo-glycals displaying two electron-withdrawing groups and was applied to eight different carbohydrates from the furanose and pyranose series. The Z/E configurations of these tetrasubstituted enol ethers could be ascertained using NMR spectroscopic techniques. Deprotection of an exo-glycal followed by an UMP (uridine monophosphate) coupling generated two new UDP (uridine diphosphate)-galactofuranose analogues...

Objective Orotic aciduria and deficiency of uridine monophosphate synthetase have been observed in a patient, studied over 10 years, who had no megaloblastic anemia. Excretion of orotic acid and orotidine were 8.24 and 0.52 mmol/mol of creatinine. The ratio of 15.85 differed appreciably from that of 6 patients reported with no megaloblastic anemia. Methods The analysis of orotidine by gas chromotography mass spectrometry was conducted. Conclusion Patients with orotic aciduria with and without megaloblastic anemia cannot be distinguished by ratio of orotic acid to orotidine...

RNA is a linear polymer of nucleotides linked by a ribose-phosphate backbone. Polymerization of nucleotides occurs in a condensation reaction in which phosphodiester bonds are formed. However, in the absence of enzymes and metabolism there has been no obvious way for RNA-like molecules to be produced and then encapsulated in cellular compartments. We investigated 5'-adenosine monophosphate (AMP) and 5'-uridine monophosphate (UMP) molecules confined in multi-lamellar phospholipid bilayers, nanoscopic films, ammonium chloride salt crystals and Montmorillonite clay, previously proposed to promote polymerization...

Glioblastoma (GBM), one of the most malignant human cancers, frequently recurs despite multimodal treatment with surgery and chemo/radiotherapies. GBM-initiating cells (GICs) are the likely cell-of-origin in recurrences, as they proliferate indefinitely, form tumors in vivo, and are resistant to chemo/radiotherapies. It is therefore crucial to find chemicals that specifically kill GICs. We established temozolomide (the standard medicine for GBM)-resistant GICs (GICRs) and used the cells for chemical screening...

Resistance to azacitidine is a major issue in the treatments of myelodysplastic syndrome and acute myeloid leukemia, and previous studies suggest that changes in drug metabolism are involved in the resistance. Therefore, drugs with mechanisms resistant or alternative to such metabolic changes have been desired for the treatment of resistant disease. We generated azacitidine-resistant cells derived from SKM-1 and MOLM-13 leukemia cell lines in vitro, analyzed the mechanisms, and examined the impact on the efficacy of other antimetabolic drugs...

Metabolomics is used to assess the compliance and bioavailability of food components, as well as to evaluate the metabolic changes associated with food consumption. This study aimed to analyze the effect of consuming ready-to-eat meals containing a cocoa extract, within an energy restricted diet on urinary metabolomic changes. Fifty middle-aged volunteers [30.6 (2.3) kg m(-2)] participated in a 4-week randomised, parallel and double-blind study. Half consumed meals supplemented with 1.4 g of cocoa extract (645 mg polyphenols) while the remaining subjects received meals without cocoa supplementation...

Uridine is a natural nucleoside precursor of uridine monophosphate in organisms and thus is considered to be safe and is used in a wide range of clinical settings. The far-reaching effects of pharmacological uridine have long been neglected. Here, we report that the homeostatic disorder of uridine is carcinogenic. Targeted disruption (-/-) of murine uridine phosphorylase (UPase) disrupted the homeostasis of uridine and increased spontaneous tumorigenesis by more than 3-fold. Multiple tumors (e.g., lymphoma, hepatoma and lung adenoma) occurred simultaneously in some UPase deficient mice, but not in wild-type mice raised under the same conditions...

A rapid method for the quantification of five ribonucleotides 5'- monophophates (adenosine, cytidine, guanosine, inosine, uridine, 5'-monophosphate), in infant formula, has been proposed using nano-LC. To separate the studied compounds, capillary columns packed with different C18-based stationary phases were investigated. All the columns tested were laboratory prepared. The experiments were performed in ion-pairing RP chromatographic mode using tetrabutylammonium hydroxide as ion-pairing reagent. The method was developed using a core-shell XB-C18 capillary column with a mobile phase consisting of 5% v/v methanol and 95% v/v 100 mM ammonium formate, pH 8, containing 20 mM tetrabutylammonium hydroxide...
