Abstract

The purpose of this study was to create an open access repository of validated liquid chromatography tandem mass spectrometry (LC-MS/MS) multiple reaction monitoring (MRM) methods for quantifying 284 important proteins associated with drug absorption, distribution, metabolism, and excretion (ADME). Various in silico and experimental approaches were used to select surrogate peptides and optimize instrument parameters for LC-MS/MS quantification of the selected proteins. The final methods were uploaded to an online public database (QPrOmics; www.qpromics.uw.edu/qpromics/assay/), which provides essential information for facile method development in triple quadrupole mass spectrometry (MS) instruments. To validate the utility of the methods, the differential tissue expression of 107 key ADME proteins was characterized in the tryptic digests of the pooled subcellular fractions of human liver, kidneys, intestines, and lungs. These methods and the data are critical for development of physiologically based pharmacokinetic (PBPK) models to predict xenobiotic disposition.

  • A previously reported database proposed surrogate peptides and LC-MS/MS parameters for NAT1 and NAT2 but did not provide quantitative data.

    “A previously reported database of proteins for quantitative analysis proposed surrogate peptides and LC-MS/MS parameters for NAT1 and NAT2, but did not provide any quantitative data.51”

    From N-Acetyltransferase (NAT) 1 and NAT2 Enzyme Activities Drive Interindividual Variability in Sulfamethoxazole N-Acetylation (2025) · cites this paper as [51]

    The Methods (Surrogate peptide selection; page unavailable) describe selecting surrogate peptides and generating MS settings, and the Results (QPrOmics workflow; page unavailable) list peptide sequences and LC-MS/MS parameters as database outputs. But the claim that the paper provided no quantitative data is too broad: the Results (Differential tissue expression of drug metabolizing enzymes; page unavailable) report measured expression and relative inter-tissue variability. The available results do not establish whether expression values were provided specifically for NAT1 or NAT2. (LLM, conf=0.87)

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.
