LC-HRMS analysis of phospholipids bearing oxylipins

Analytica Chimica Acta
Several oxylipins including hydroxy- and epoxy-polyunsaturated fatty acids (PUFA) act as lipid mediators. In biological samples they dominantly occur esterified in phospholipids (PL). Esterified oxylipins are usually quantified indirectly after alkaline hydrolysis as non-esterified oxylipins.

Small‐Molecule Activation of mRNA Translation by Click‐to‐Release Reaction in Cells

Angewandte Chemie, EarlyView.
A new method to control mRNA activity using bioorthogonal click‐to‐release reactions is presented. The 5′ cap is modified with a trans‐cyclooctene (TCO) that quickly reacts with hydroxyaryl‐tetrazines and efficiently releases the native cap 0. TCO‐capped mRNAs are initially translationally inactive but can be activated with non‐toxic, cell‐permeable ...
