Daniel Krug 1,2, Carsten Volz 1, Aiko Barsch 3, Chris Beecher 4, Felice de Jong 4, Rolf Müller 1,2
Comprehensive study of regulation in myxobacteria with an untargeted metabolomics setup using Isotopic Ratio Outlier Analysis (IROA) and UHR-Q-TOF
Reliable relative quantitation of known and unknown metabolites from a myxobacterial mutant strain in response to induction of the transcriptional antirepressor taA
Compound identification facilitated by the use of ultra-high resolution MS and the knowledge of the number of carbons in each molecule due to IROA
|Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.|
Albillos SM; Balaña-Fouce R; Montero O; Barreiro-Mendez C; Blas-Galindo E; Barros-García R; Guedella-Bustamante E; Ullán RV
BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.
|Rapid Identification of Microorganisms by Touch Spray and Paper Spray Ambient Ionization|
Ahmed M. Hamid, Alan K. Jarmusch, Valentina Pirro and R. Graham Cooks
The rapid and accurate identification of microorganisms is necessary in order to improve public health. Molecular-based identification allows for rapid patient treatment and provides more accurate diagnoses, two crucial aspects for successful treatment, yet a great challenge. In this work PS-MS, an existing ambient method, and TS-MS, a newly developed technique, are being utilized in the rapid discrimination of microorganisms (<2 min).

|QSAR Model of Regioselectivity of Metabolism in Human Liver Microsomes: Development, Validation, Comparison and Adaptation to Novel Compounds|
Justas Dapkunas, Andrius Sazonovas and Pranas Japertas
Analytical identification of metabolites for a drug candidate is usually a time consuming and low-throughput task which is performed only in late drug development phases. Therefore the ability to predict possible sites of human liver microsomal metabolism using in silico techniques would be highly beneficial for any medicinal chemist.
|In silico Identification of Metabolic Soft Spots: Case Study Using ACD/ADME Suite Software|
Justas Dapkunas, Andrius Sazonovas, Remigijus Didziapetris and Pranas Japertas
Metabolic stability, determined in liver microsomes, is one of the primary assays used in early drug discovery. A key factor limiting compound half-life is the cytochrome P450 mediated metabolism. High clearance by these enzymes implies a higher and more frequent dosing as well as poses a risk for individual variations in exposure.
|Analytical and Chemical Knowledge Management Software for Drug Metabolism Science|
Graham A. McGibbon, Karim Kassam, and Susan Ling
Characterizing metabolite structures and metabolic pathways is essential to understanding the potential biological implications of compounds in drug discovery.
