Mass-MetaSite

High-Throughput MetID

Mass-MetaSite is an established approach for the automatic identification of metabolites for small molecules and peptides using Liquid Chromatography - Mass Spectrometry, UV, fluorescencem, and radio-chromatogram data, reducing manual analysis from several hours to only a few minutes per compound [1]. The program is able to assign chemical structures to each automatically detected chromatographic peak based on the MS and MS/MS fragmentation pattern of the substrates and metabolites. It can process from multiple vendors (Agilent, Bruker, Sciex, Thermo, and Waters) and it is also available to analyze data from different acquisition modes (DDA, MSE, HDMSE, AIF, AF, Broad band, SWATH, Sonar, etc.)

In the cases where the data cannot be used to propose a single structure for the chromatographic peaks found, the system also introduces the Site of Metabolism (SoM) prediction from MetaSite computation (the leader in the metabolism prediction market), that ranks the multiple structural options. Moreover, the user has access to the visual analysis of the enzyme-metabolite interaction CYPs, FMO and AOX proteins, and it can even propose structural modification to overcome the metabolic liability.

The auto-process and the batch processor enable the use of the software for automatic process in ADME workflows like GSH, Met ID, Soft Spot and much more.
