Reactions and enzymes in the metabolism of drugs and other xenobiotics

Testa, Bernard, Pedretti, Alessandro, Vistoli, Giulio·2012·Drug Discovery Today

Abstract

In this article, we offer an overview of the compared quantitative importance of biotransformation reactions in the metabolism of drugs and other xenobiotics, based on a meta-analysis of current research interests. Also, we assess the relative significance the enzyme (super)families or categories catalysing these reactions. We put the facts unveiled by the analysis into a drug discovery context and draw some implications. The results confirm the primary role of cytochrome P450-catalysed oxidations and UDP-glucuronosyl-catalysed glucuronidations, but they also document the marked significance of several other reactions. Thus, there is a need for several drug discovery scientists to better grasp the variety of drug metabolism reactions and enzymes and their consequences.

  • A meta-analysis of the metabolic fate of more than 1000 xenobiotics showed that cytochrome P450-catalyzed oxidations (40%) and UDP-glucuronosyltransferase glucuronidations (14%) were most common, followed by dehydrogenases (8%), hydrolases (7%), glutathione-S-transferases (6%), and sulfatases (5%).

    “A recent meta-analysis (68) of the metabolic fate of .1000xenobiotics showed that cytochrome P450 catalyzed oxidations (40%) and UDP-glucuronosyltransferase glucuronidations (14%) were the most common followed by reactions involving dehydrogenases (8%), hydrolases (7%), glutathione-S-transferases (6%), and sulfatases (5%).”

  • The yield of phase I/II reactions is often very high, and host-transformed metabolites retain many features of their parent compounds.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
