• trisodium salt
  • Combination therapy using nebulized amiloride hydrochloride and uridine-5'-triphosphate (UTP) trisodium salt aerosols has been investigated for the treatment of cystic fibrosis (CF). Amiloride in aqueous solution precipitates in the presence of UTP, reducing drug concentrations. (rti.org)
  • polymerase
  • As an example, 1-(3-C-ethynyl-β-D-ribopentofuranosyl)cytosine (ECyd) and 1-(3-C-ethynyl-β-D-ribopentofuranosyl)uridine (EUrd) are RNA polymerase inhibitors that are under investigation for use as anticancer drugs. (wikipedia.org)
  • Sofosbuvir, on the other hand, is metabolized to a uridine triphosphate mimic, which acts as a RNA chain terminator when incorporated into RNA by NS5B polymerase. (wikipedia.org)
