Mass spectrometry of dendrimers

Mass Spectrometry Reviews, EarlyView.
Abstract Mass spectrometry (MS) has become an essential technique to characterize dendrimers as it proved efficient at tackling analytical challenges raised by their peculiar onion‐like structure. Owing to their chemical diversity, this review covers benefits of MS methods as a function of dendrimer classes, discussing advantages and limitations of ...

Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.

The Quinoline Photoremovable Group (PPG) Platform—A Medicinal Chemist's Approach for Photocage Development and Applications

Medicinal Research Reviews, EarlyView.
ABSTRACT Photoremovable protecting groups (PPGs) offer a straightforward solution for the temporary inactivation of biologically active substrates and their subsequent controlled release by light irradiation. Their relatively easy design and mode of application have made them useful tools for studying dynamic biological processes in vitro and in vivo ...

Reactivity of Imidazole‐ and Pyridine‐Carboxaldehydes for Gem‐Diol and Hemiacetal Generation: Theoretical and Experimental Insights

ChemistryOpen, EarlyView.
The generation of the gem‐diol and hemiacetal forms using pyridine‐ and imidazole‐carboxaldehyde isomers in different chemical environments was studied by NMR spectra and combined with theoretical calculations. Unlike aprotic solvents, protic ones, as water and methanol, favored the generation of the gem‐diol and hemiacetal structures.
