Description

Spectral data and metadata for the puplication: "Polypharmacology-Labeled Molecular Networking: An Analytical Technology Workflow for Accelerated Identification of Multiple Bioactive Constituents in Complex Extracts" || Yong Zhao, Oliver Gericke, Tuo Li, Louise Kjaerulff, Kenneth T. Kongstad, Allison M. Heskes, Birger L. Moeller, Henrietta Venter, Sonia Coriani, Susan J. Semple, and Dan Staerk* || Bioassay data || Bioassay data includes anti-diabetic and anti-bacterial activity of microfractions from Eremophila rugosa crude leaf extract.The file "Erugosa_bioassay_data.txt" contains bioassay data. Collection of fractions are indicated with retention time: start and end of microfraction collection as well as average collection time. Anti-diabetic bioassays include alpha-glucosidase and PTP1B inhibition in percentage. Anti-microbial bioassays include S. epidermidis, S. aureus, S.aureus MRSA, E.faecium and E.faecium VRE growth inbition in percentage. For comparision, bioassay data was normalized to the largest value observed per assay. These values are indicated in additional columns. || UV data || UV absorbance was determined for wavelengths 210 nm and 280 nm at different retention time points. The file "Erugosa_UV_data.txt" contains UV data. || In silico dereplication through network annotation propagation(NAP) || The file "Erugosa_ISDB.tsv" was used within the NAP workflow on GNPS to achieve an enhanced chemical classification of the studied spectral dataset derived from Eremophila rugosa leaf extract. The file "Erugosa_ISDB.txt" contains the underlying SMILES strings and compound identifiers used to establish this spectral database. The majority of compound names with the identifier "Singab_#" relate to compounds described in Singab et al. 2013 chemical review [1], whereas "KU" compounds are presented within the manuscript. Other compound identifiers used in this study are: Zhao2019_Ebignoniiflora_# [2], BCFA_# [3], Tahtah_# [4], Wubshet_# [5], Bee_Mi_# [6], LK_Mi_# [7], Duke_Mi_# [8]. [1] Singab, A. N., Youssef, F.

Click here to queue conversion of this dataset's submitted spectrum files to open formats (e.g. mzML). This process may take some time.

When complete, the converted files will be available in the "ccms_peak" subdirectory of the dataset's FTP space (accessible via the "FTP Download" link to the right).
Number of distinct conditions across all analyses (original submission and reanalyses) associated with this dataset.

Distinct condition labels are counted across all files submitted in the "Metadata" category having a "Condition" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct biological replicates across all analyses (original submission and reanalyses) associated with this dataset.

Distinct replicate labels are counted across all files submitted in the "Metadata" category having a "BioReplicate" or "Replicate" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct technical replicates across all analyses (original submission and reanalyses) associated with this dataset.

The technical replicate count is defined as the maximum number of times any one distinct combination of condition and biological replicate was analyzed across all files submitted in the "Metadata" category. In the case of fractionated experiments, only the first fraction is considered.

"N/A" means no results of this type were submitted.
Originally identified proteins that were automatically remapped by MassIVE to proteins in the SwissProt human reference database.

"N/A" means no results of this type were submitted.
Number of distinct protein accessions reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct unmodified peptide sequences reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct peptide sequences (including modified variants or peptidoforms) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Total number of peptide-spectrum matches (i.e. spectrum identifications) reported across all analyses (original submission and reanalyses) associated with this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins quantified across all analyses (original submission and reanalyses) associated with this dataset.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
Number of distinct proteins found to be differentially abundant in at least one comparison across all analyses (original submission and reanalyses) associated with this dataset.

A protein is differentially abundant if its change in abundance across conditions is found to be statistically significant with an adjusted p-value <= 0.05 and lists no issues associated with statistical tests for differential abundance.

Distinct protein accessions are counted across all files submitted in the "Statistical Analysis of Quantified Analytes" category having a "Protein" column in this dataset.

"N/A" means no results of this type were submitted.
This dataset may not contain all raw spectra data as originally deposited in PRIDE. It has been imported to MassIVE for reanalysis purposes, so its spectra data here may consist solely of processed peak lists suitable for reanalysis with most software.
