Dihydropyridines Potentiate ATP-Induced Currents Mediated by the Full-Length Human P2X5 Receptor
Molecules, 2022 The P2X5 receptor, an ATP-gated cation channel, is believed to be involved in tumor development, inflammatory bone loss and inflammasome activation after bacterial infection. Therefore, it is a worthwhile pharmacological target to treat the corresponding

European Journal of Organic Chemistry, EarlyView.The intramolecular nitrile oxide olefin [3 + 2]‐cycloaddition offers a reliable entry toward 2‐aza‐bicyclo[4.3.0]‐nonanes, a substructure found in several bioactive piperidine alkaloids. The required oxime precursors were prepared in non‐racemic form by Ir‐catalyzed asymmetric allylation and ring‐closing metathesis.
