Direct Ionization of Solid-Phase Microextraction Fibers for Quantitative Drug Bionalysis : From Peripheral Circulation to Mass Spectrometry Detection
Sheelan, Ahmad,; Michael, Tucker,; Neil, Spooner,; Murnane, Darragh; Gerhard, Ute (2015-01-06)A novel approach is described for the quantitative bioanalysis of drugs in blood samples by ionization of the analytes collected on solid-phase microextraction (SPME) fibers by mass spectrometry (MS). The technique combines ... -
Fractionlynx for mass directed purification of metabolites : an alternative tool to get a metabolite into a NMR magnet
Gunn, David; Kingston, Jenny; Thomas, S R; Mortishire-Smith, R J; Gerhard, Ute (2005) -
The fragmentation behaviour of alkylated thiophene-1,1-dioxides
Budzikiewicz, Herbert; Gerhard, Ute (1989) -
The Khat and Meow Meow Tale : Teaching the Relevance of Chemistry through Novel Recreational Drugs
Fergus, Suzanne; Kellett, Kathryn; Gerhard, Ute (2015)Using current research and real-life scenarios to motivate students to understand chemistry principles is a key strategy in learning and teaching. An illustration of psychoactive drugs referred to as “legal highs” used in ... -
Ligands which bind weakly to vancomycin : Studies by 13C NMR spectroscopy
Pearce, C.M.; Williams, D.H.; Gerhard, Ute (1995-01-01)C NMR chemical shifts of vancomycin have been used to obtain the association constants for a number of ligands which bind weakly to the antibiotic. The change in these C chemical shifts upon stepwise addition of ligands ... -
Neighbouring Group Participation of the Indole Nucleus : An Unusual DAST Mediated Rearrangement Reaction Monitored by Low Temperature NMR Spectroscopy
Gerhard, Ute; Goodacre, S.C.; Hallett, D.J.; Rowley, M.; Sparey, T.J.; Thomas, S R (1999) -
Open-access high-resolution mass spectrometry in early drug discovery
Thomas, S. R.; Gerhard, Ute (2004-08)Techniques such as mass spectrometry and NMR spectroscopy form an essential part of the medicinal chemist's toolbox for characterizing and assessing the purity of new molecules. Empowering medicinal chemists to gain early ... -
Optimisation of a Non-Commercial Loop-Storage Unit and Comparison with Continuous-Flow and Stopped-Flow Experiments in LC-NMR
Bailey, Nigel J.; Crowe, Eleanor A.; Gerhard, Ute; Roberts, John K. (1995) -
Small molecule recognition of mephedrone using an anthracene molecular clip
Kellett, Kathryn; Broome, J. Hugh; Zloh, Mire; Kirton, Stewart B.; Fergus, Suzanne; Gerhard, Ute; Stair, Jacqueline L.; Wallace, Karl J. (2016-05-16)An anthracene molecular probe has been synthesised and shown to target mephedrone, a stimulant drug from the cathinone class of new psychoactive substances (NPS). A protocol has been developed to detect mephedrone via the ... -
Solid-phase microextraction for assessment of plasma protein binding, a complement to rapid equilibrium dialysis
Sheelan, Ahmad,; Baker, Daniel; Murnane, Darragh; Neil, Spooner,; Gerhard, Ute (2021-07-19)Aim: Determination of plasma protein binding (PPB) is considered vital for better understanding of pharmacokinetic and pharmacodynamic activities of drugs due to the role of free concentration in pharmacological response. ... -
Synthesis and Spectral Characterization of Benzo[6,7] [1,5]diazocino[2,1-a]isoindol-12-(14H)-one Derivatives
Bassin, Jatinder; Anagani, Bhavani; Benham, Christopher; Goyal, Madhu; Hashemian , Maryam; Gerhard, Ute (2016-07-23)A simple synthetic route to benzo[6,7][1,5]diazocino[2,1-a]isoindol-12(14H)-one ring system is developed from readily available starting materials 3-(2-oxo-2-phenylethyl) isobenzofuran-1(3H)-ones and 2-(aminomethyl)aniline ...
