Project description:mzXMLs from NIH Natural Product Library. Included are methods for dilution and LC-MS/MS acquisition, plate maps, excel file of compounds added to gnps and structures generated from SMILES.
Project description:NIH NPAC ACONN Natural Products 2179 Standards analyzed by untargeted LC-MS/MS in negative ion mode part 2. Note that each 96 well plate was divided as following: - One row represents a single plate. - Each well represents the pooling of the wells belonging to the same column for the corresponding plate. The MS/MS spectra have been uploaded on GNPS spectral library using an in-house script. Several adducts were retrieved for each compound. Some compounds could not be found during this process. Compound list can be found in Supplementary Files, as well as the LC-MS method used. Note that this dataset has been analyzed using one single LC method for both positive and negative ionization.
Project description:NIH NGC Natural Products run by the Dorrestein Lab - 2406 Standards analyzed by untargeted LC-MS/MS in positive negative mode part 1. Note that each 96 well plate was divided as following: - One row represents a single plate. - Each well represents the pooling of the wells belonging to the same column for the corresponding plate. The MS/MS spectra have been uploaded on GNPS spectral library using an in-house script. Several adducts were retrieved for each compound. Some compounds could not be found during this process. Compound list can be found in Supplementary Files, as well as the LC-MS method used. Note that this dataset has been analyzed using one single LC method for both positive and negative ionization. Except few plates that were run with shorter LC-MS run in negative ion mode.

Project description:Natural products exhibit potential as candidates for developing multi-target agents for Alzheimer's disease treatment. The aim of this study is to utilize network-based medicine to identify novel natural products for Alzheimer's disease, and investigate their efficacy and mechanisms of action. In this study, we identified (-)-Vestitol and Salviolone as new potential natural products for treating Alzheimer's disease via an Alzheimer's disease-related pathway-gene network. Both natural products improved the cognition of APP/PS1 transgenic mice, reduced Aβ deposition, and lowered soluble toxic Aβ levels in the brain. Notably, a synergistic effect was observed when the two natural products were combined. Transcriptomic analysis and qRT-PCR experiments revealed that the synergistic mechanism of (-)-Vestitol and Salviolone combination is associated with the regulation of a broader range of AD-related pathways and genes, particularly the neuroactive ligand-receptor interaction pathway and calcium signaling pathway.
