单词 prodrug
释义

Definition of prodrug in English:

prodrug

noun ˈprəʊdrʌɡˈprōˌdrəɡ
  • A biologically inactive compound which can be metabolized in the body to produce a drug.

    药物前体,前药

    Example sentencesExamples
    • This involves gene transfer of an enzyme into tumour cells, which converts an inactive prodrug into a toxic metabolite, leading to cell death.
    • Bouncing powerful X-rays off the protein crystals yielded a three-dimensional image of the dual protein structure, showing them exactly how the prodrug and the enzyme interact.
    • It is a prodrug that is converted intracellularly to various metabolites that bind to the enzyme thymidylate synthase, inhibiting synthesis of thymidine, DNA, and RNA.
    • As the prodrug is metabolically converted to its cytotoxic form, it penetrates the cell bearing the bound enzyme as well as ‘naked’ cells that are nearby.
    • An ester prodrug was shown to increase the bioavailability of MPA following oral administration.
    • The use of targeting antibodies conjugated to enzymes that selectively activate antineoplastic prodrugs on or near cancer cells (known as antibody-directed enzyme prodrug therapy, or ADEPT) is also addressed.
    • At Cardiff, she is promoting a more proactive role for polymers: ‘as integral parts of therapeutics, which could be thought of as macromolecular prodrugs, or even as drugs in their own right’.
    • The antihistamine loratidine is one example of a prodrug that must be activated by liver enzymes to be effective, the researchers pointed out in their paper.
    • Valacyclovir, a prodrug that metabolizes to acyclovir, has better bioavailability and requires less frequent dosing than acyclovir.
    • They waited a bit to give the unbound nanobodies time to filter out of the body, then injected the prodrug.
    • The improvement of bioavailability of ALA by application of ALA esters is determined by two processes: the rate of diffusion of the prodrug through the cell membrane and its rate of enzymatic conversion into ALA.
    • The influence of branching on the enzymatic stability of the compounds was investigated, as it is known that sterically hindered ester prodrugs are more stable toward enzymatic hydrolysis.
    • ALA is a prodrug and is being used as a photodynamic diagnosis agent in head and neck cancers.
    • Cefuroxime axetil is the ester prodrug of cefuroxime sodium, suitable for oral administration.
    • Codeine, a prodrug, depends on P450 metabolism to morphine for its analgesic effect.
    • Here the enzyme lays dormant until non-toxic drugs, called prodrugs, are given.
    • In summary, this study has confirmed quantitatively the considerable degree to which the delivery of the ALA prodrug can be enhanced by iontophoresis of the simple, cationic alkyl esters at neutral pH.
    • A second important aspect of the invention is to have the second binding head capture or contain an enzyme that activates a prodrug substrate.
    • In addition, the drugs which can increase GSH content, such as cysteine prodrugs, will also reduce acetaminophen hepatotoxicity.
    • While remaining innocuous to the normal tissues, the prodrug is converted to the cytotoxin by the enzyme localised at the tumour.
