Findings of Merit: Sequential transfer of media w/ terfenadine, trimethylamine, and vitamin D between gut, liver, and kidney organotypic culture models demonstrating absorption, metabolism and clearance along with exposure of neurovascular and skeletal muscle models. Data showed organ-specific processing of compounds consistent w/ clinical data and discovered trimethylamine-N-oxide (TMAO) crosses the blood-brain barrier.
DoddsJN, May JC, McLean JA. “Investigation of the Complete Suite of the Leucine and Isoleucine Isomers: Toward Prediction of Ion Mobility Separation Capabilities”, Anal. Chem. 89, 952−959, Dec 2016. DOI: 10.1021/acs.analchem.6b04171
Findings of Merit: Study to separate isometric mixtures using 11 isomers of C6H13NO2 (m/z 131) via drift tube ion mobility mass spectrometry. Correlation of gas-phase collision cross section (CCS) and resolution enables the development of computational approaches to predict separation of any two compounds with known CCS for ion-mobility instruments w/ well characterized resolving power. A mathematical relationship relating the CCS to resolving power was developed in order to predict the required ion mobility resolving power needed to separate the various isomer classes.
