Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

Angewandte Chemie, EarlyView.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Ribozyme für die RNA‐katalysierte Methylierung und Markierung von RNA

Angewandte Chemie, EarlyView.
Ribozyme sind vielseitige Werkzeuge für die präzise Modifikation von RNA. Das Reaktionsspektrum in‐vitro‐selektierter Ribozyme reicht vom Einbau funktioneller Gruppen und Fluorophoren bis zu natürlichen RNA‐Methylierungen. Dieser Übersichtsartikel präsentiert Cofaktor‐abhängige Ribozyme für die positionsgenaue Markierung und Modifikation von RNA ...

Azide‐to‐Diazo Transformation Facilitated by Michael Addition via Phosphazide Formation

Angewandte Chemie, EarlyView.
A new type of Michael addition based on azide‐to‐diazo conversion is disclosed. This unusual transformation proceeds via 1,4‐addition accompanied by N─N bond cleavage of phosphazide intermediates under practical conditions. The high versatility of the resulting Michael adducts enables the synthesis of a wide variety of organonitrogen compounds ...

Nano‐Gs‐Protein Peptidomimetika: Rationales Design von Peptiden, die vom C‐Terminus von Gα abgeleitet sind und Schlüsselkomponenten der Gs‐β2AR‐Wechselwirkungen nachahmen

Angewandte Chemie, EarlyView.
G Protein‐gekoppelte Rezeptoren (GPCRs) sind wichtige therapeutische Zielstrukturen. Die Modulation der GPCR‐Aktivität über intrazelluläre Bindungsstellen gewinnt zunehmend an Bedeutung. Ein strukturell und computergestützter Ansatz ermöglichte die Entwicklung kleiner, vom G Protein abgeleiteter Peptidomimetika, die gezielt an die intrazelluläre ...

Alkyltransferase Ribozyme for Site‐Specific N4‐Cytidine Alkylation

Angewandte Chemie, EarlyView.
CSAR is the first ribozyme that catalyzes direct alkylation of an exocyclic amino group of an RNA nucleobase. The ribozyme was isolated as a self‐labeling catalyst from an in vitro selection library and engineered into a trans‐active ribozyme that catalyzes the transfer of a benzyl group from an O6‐modifed guanine to the N4 amino group of a specific ...

Synthetic O‐Polysaccharide Backbone Units for a Single Antigen Vaccine Against Two Major Non‐Typhoidal Salmonella Serovars

Angewandte Chemie, EarlyView.
A modular strategy was developed to synthesize tri‐, hexa‐, and nona‐saccharides representing repeating units of the conserved O‐polysaccharide backbone of Salmonella. Conjugates of these glycans to bacteriophage Qβ induced strong IgG responses in mice and rabbits. Antibodies elicited recognized native O‐polysaccharides and conferred protection against
