The advantage of 35 S, when compared to other short-lived isotopes, is its relatively low signal (which contributes to a sharp band width), as well as longer . Affected cytochrome P450 isoenzymes and transporters: P-glycoprotein (P-gp) In vitro data showed that uridine triacetate was a weak substrate for P-gp; uridine triacetate also inhibited the transport of digoxin (a known P-gp substrate). And it can be used as auxiliary liver disease drug. Peak plasma concentration of uridine occurs 2-3 hours after oral administration of triacetyluridine. A pyrimidine ribonucleoside 5'-monophosphate having 5-fluorouracil as the pyrimidine component. The uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) is an important member of the UGT1A family.
