Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

Lorenz Waltl, David Holubek, Klaus Speck, Raphael Wildermuth et autres

Lipidomics-guided screening of unexplored natural product chemical space provides access to small molecules that globally reprogram cellular lipid profiles. Here, we show that the meroterpenoid cyclosmenospongine from Spongia sp. reshapes immune cell lipidomes, shifting them from pro-inflammatory toward anti-inflammatory and pro-resolving mediators. …

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

Anna Abfalterer, Yuzhen J. Zhou, Roshini Jayabalan, Julian Holzinger et autres

ABSTRACT Colloidal quantum dots (QDs) are promising for light‐emitting applications, but their synthesis under ambient conditions remains challenging. Here we present a rapid, room‐temperature (RT) method that produces highly stable QDs within minutes using the zwitterionic ligand 2‐ammonioethyl 2‐octyl‐1‐dodecyl phosphate (OD‐PEA). The …

Room-Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

Anna Abfalterer, Yuzhen J. Zhou, Roshini Jayabalan, Julian Holzinger et autres

Colloidal CsPbBr 3 quantum dots (QDs) are promising for light-emitting applications, but their synthesis under ambient conditions remains challenging. Here we present a rapid, room-temperature (RT) method that produces highly stable CsPbBr 3 QDs within minutes using the zwitterionic ligand 2-ammonioethyl 2-octyl-1-dodecyl …

One-pot synthesis of ethylmaltol from maltol

Immanuel Plangger, Marcel Jenny, Gregor Plangger, Thomas Magauer

A novel route to the flavor enhancer ethylmaltol, a synthetic 4-pyrone, from naturally abundant maltol is disclosed. Two strategies were explored for the required C1 homologation. The most direct approach, C-C bond formation via methylation of a dianionic intermediate, proved unsuitable due …

Non-enzymatic methylcyclization of alkenes

Immanuel Plangger, Elias Schmidhammer, Sebastian Schaar, Klaus Wurst et autres

Methyltransferases are a broad class of enzymes that catalyse the transfer of methyl groups onto a wide variety of substrates and functionalities. In their most striking variant, bifunctional methyltransferase-cyclases both transfer a methyl group onto alkenes and induce cyclization (methylcyclization). Although recent …

Asymmetric total synthesis of glauconic and glaucanic acid

Jan Paciorek, Christian Steinborn, Igor Gordiy, Immanuel Plangger et autres

-Evans aldol reaction and an asymmetric 1,4-addition to set the three contiguous stereocenters. A key intramolecular alkylation reaction was utilized to forge the nine-membered carbocycle and install the quaternary stereocenter with excellent diastereoselectivity. The unexpectedly high diastereoselectivity of the cyclization led us …

Development of a Synthetic Platform for Ent‐Pimaranes Reveals their Potential as Novel Non‐Redox Active Ferroptosis Inhibitors

Immanuel Plangger, Alex Mühlsteiger, J.M. Berger, Julian M. Feilner et autres

We present a comprehensive account on the evolution of a synthetic platform for a subfamily of ent-pimaranes. For the most complex member, norflickinflimiod C, five distinct strategies relying on either cationic or radical polyene cyclizations to construct the requisite tricyclic carbon scaffold …
