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.
converts to CTP in the brain which increases the level of CDP-diacylglycerol, which is a substrate required for PI synthesis .
According to the difference in the time points, uridine
, inosine, guanosine, safflomin A, and brazilin were obtained.
1: Lipids C[H.sub.3], branched chain amino acids; 2: Lipids C[H.sub.2]; 3: Lactate (Lac); 4: Alanine (Ala); 5: Glutamine (Gln), Glutamic acid (Glu); 6: Creatine (Cr); 7: Choline (Cho), Phosphocholine (PC); 8: Glycerophosphocholine (GPC); 9: Taurine (Tau); 10: Glycine (Gly); 11: [beta]-Glucose ([beta]-Glc); 12: Uridine
5'-diphospho-N- acetylglucosamine or Uridine
5'-diphospho-N-acetylgalactosamine (UDP); 13: Nicotinamide adenine dinucleotide 2'- diphosphate ([NADP.sup.+]).
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
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).
Almac Group's long-term client partner, Wellstat Therapeutics, received commercial approval of its first orphan drug product XURIDEN (uridine
triacetate) for the treatment of rare disease Hereditary Orotic Aciduria (HOA).
