title: MassIVE MSV000088442 - GNPS - hypoglycemic and antibacterial diterpenoids in Eremophila rugosa
title: Spectral data and metadata for the manuscript: "Polypharmacology-labelled molecular networking for discovery of hypoglycemic and antibacterial diterpenoids in the Australian desert plant Eremophila rugosa" || 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.
