The thymocyte-specific RNA-binding protein Arpp21 provides TCR repertoire diversity by binding to the 3’-UTR and promoting Rag1 mRNA expression

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-20 (2024)

Abstract The regulation of thymocyte development by RNA-binding proteins (RBPs) is largely unexplored. We identify 642 RBPs in the thymus and focus on Arpp21, which shows selective and dynamic expression in early thymocytes. Arpp21 is downregulated i

Stereoselective P5-Deltacyclene Alkylation, an Efficient Route to New Asymmetric P-C-Cage Compounds

Autor: Irene C. Keller, Frank W. Heinemann, Ulrich Zenneck, Lars Rohwer, Christine Höhn

Publikováno v: Zeitschrift für anorganische und allgemeine Chemie. 643:922-931

Tetra-tert-butyl-P5-deltacyclene 5 represents one of only two asymmetric P-C cage compounds, which are available in highly enantiomerically enriched versions. This paper reports about stereoselective substitution reactions of 5 to develop the chemist

Dimeric P 5 -deltacyclene complexes: Variation of bridging modes and intact or partially opened P C cage ligand structures

Autor: Christine Höhn, Lars Rohwer, Irene C. Keller, Ulrich Zenneck, Frank W. Heinemann

Publikováno v: Journal of Organometallic Chemistry. 821:91-99

Chiral P C cage compound tetra-tert-butyl-P5-deltacyclene 7 and the coinage metal salts CuCl, CH3COOAg, and (PPh3)AuCl form binuclear complexes with the metal atoms in the bridging position. In the case of copper, a Cu2Cl2 ring connects two intact li

Optically Active P 5 ‐Deltacyclenes: A Unique Cage‐Inversion Reaction and Some Transition‐Metal Complexes of the Rearranged Cage

Autor: Irene C. Keller, Walter Bauer, Ulrich Zenneck, Frank W. Heinemann, Christine Höhn, Tatyana E. Shubina, Lars Rohwer, Sergi Huguet Torrell

Publikováno v: European Journal of Inorganic Chemistry. 2016:691-699

Cage-chiral P5-deltacyclene 1 is available as a pair of highly enriched P–C cage enantiomers 1′ and 1″, which exist as pairs of epimers a and b. Deprotonation of cage atom P1 initiates a rearrangement reaction, in which P1 and the neighboring c

An Approach to Rigid, Optically Active Chelate Ligands with C 2 Symmetry: Dialkylhexaphosphapentaprismanes

Autor: Lars Rohwer, Ulrich Zenneck, Christine Höhn, Frank W. Heinemann, Irene C. Keller

Publikováno v: European Journal of Inorganic Chemistry. 2013:5769-5780

Diastereomeric Pd and Pt complexes with a highly rigid chelate cage ligand core have been designed on the basis of alkylated C2-symmetric tetra-tert-butylhexaphosphapentaprismanes R2P6C4tBu4. The ligands are accessible by substitution of the diiodo d

Optically active P5-deltacyclenes: selective oxidation, ligand properties, and a diastereoselective rearrangement reaction

Autor: Walter Bauer, Ulrich Zenneck, Irene C. Keller, Frank W. Heinemann, Lars Rohwer, Christine Höhn

Publikováno v: Dalton transactions (Cambridge, England : 2003). 45(17)

Cage-chiral tetra-tert-butyl-P5-deltacyclene is accessible as a pair of highly enriched enantiomers and . The only secondary phosphorus atom P1 of the cage can be selectively oxidized by reaction with t-BuOOH. The P1-oxo species and , allow the direc
