uridine

 [u´rĭ-dēn]
a ribonucleoside containing uracil.
uridine diphosphate (UDP) a nucleotide that participates in glycogen metabolism and in some processes of nucleic acid synthesis.

u·ri·dine (Urd),

(yūr'i-dēn),
Uracil ribonucleoside; one of the major nucleosides in RNAs; as the pyrophosphate (UDP, UDPG, etc.), uridine is active in sugar metabolism.

uridine

(yo͝or′ĭ-dēn′)
n.
A nucleoside, C9H12N2O6, that is composed of uracil and ribose, is a component of RNA, and plays a role in regulating many physiological processes.

uridine

The nucleoside of URACIL found in RNA and other NUCELOTIDES.

uridine

a molecule formed from a combination of a ribose sugar and the RNA base URACIL. Further addition of a phosphate group produces the NUCLEOTIDE.

From these results, we can see that all samples contained all five active ingredients, but their contents are different in samples fermented with different strains; for example, for the Jinshuibao capsules (adenosine > uridine > guanosine > adenine > uracil), Jinshuibao tablets (adenosine > uridine > guanosine > adenine > uracil), and Bailing capsule (adenosine > guanosine > uridine > uracil > adenine).
Meanwhile, Cordyceps samples were used as controls for the analysis of various nucleosides including uridine, guanosine, adenosine and cordycepin.
Likewise, uridine converts to CTP in the brain which increases the level of CDP-diacylglycerol, which is a substrate required for PI synthesis [124].

The objectives of the present study included (1) to identify through ultra-high-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF MS) and high-performance liquid chromatography-solid-phase extraction-nuclear magnetic resonance spectroscopy (HPLC-SPE-NMR) the WEL metabolites formed in rats following an oral administration of 50 mg/kg WEL; (2) to determine the uridine diphosphate-glucuronosyltransferases (UGTs) responsible for WEL glucuronidation using human liver microsomes (HLMs), human intestine microsomes (HIMs), human kidney microsomes (HKMs), and recombinant human UGT enzymes; and (3) to explore the possible mechanisms of WEL regioselective glucuronidation.
With a similar substance, KI-8115, having a modified adenosine residue bound to acetylated and carboxyl-methylated Neu5Ac, instead of uridine, synthesized by Ogura et al., 68) we could show in 1992 that the propagation of influenza viruses in cell culture was significantly inhibited (Odenthal-Schnittler, M., Schwarz, R.T.
Tritiated thymidine, uridine, and leucine incorporation assay suggest that the fraction acts directly on DNA synthesis.
A peptide unit is built on NAM (N-acetyl-muramic acid) while the sugar is attached to uridine diphosphate.
Food and Drug Administration today approved Vistogard (uridine triacetate) for the emergency treatment of adults and children who receive an overdose of the cancer treatment fluorouracil or capecitabine, or who develop certain severe or life-threatening toxicities within four days of receiving these cancer treatments.
Codeine mainly metabolizes to codeine-6-glucuronide (C6G) by uridine diphosphate glucuronosyl transferase (UGT2B7); but codeine can also undergo metabolism to morphine in the liver via cytochrome P450 2D6 (CYP2D6).
