Exploring the reactivity of N-heterocyclic diazoolefins

Diazo compounds of the type R1R2CN2 are widely used in organometallic catalysis and synthetic chemistry. Stable diazoolefins, R1R2C=CN2, have only been isolated recently. Diazoolefins undergo cycloaddition reactions and tend to be carbon donors when used a ...

Decoding Chromatin Ubiquitylation: A Chemical Biology Perspective

Beat Fierz, Pauline Franz

Since Strahl and Allis proposed the "language of covalent histone modifications", a host of experimental studies have shed light on the different facets of chromatin regulation by epigenetic mechanisms. Initially proposed as a concept for controlling gene ...

CENP-A and CENP-B collaborate to create an open centromeric chromatin state

Beat Fierz, Harsh Nagpal, Wei Cai

Centromeres are epigenetically defined via the presence of the histone H3 variant CENP-A. Contacting CENP-A nucleosomes, the constitutive centromere associated network (CCAN) and the kinetochore assemble, connecting the centromere to spindle microtubules d ...

Simultaneous mass spectrometry analysis of cisplatin with oligonucleotide-peptide mixtures: implications for the mechanism of action

Paul Joseph Dyson, Laure Menin, Luc Patiny, Daniel Ortiz Trujillo

Although genomic DNA is the primary target of anticancer platinum-based drugs, interactions with proteins also play a significant role in their overall activity. In this study, competitive binding of cisplatin with an oligonucleotide and two peptides corre ...

Orientational self-sorting in cuboctahedral Pd cages

Kay Severin, Farzaneh Fadaei Tirani, Adam Wade Marcus

Cuboctahedral coordination cages of the general formula [Pd12L24]24+ (L = low-symmetry ligand) were analyzed theoretically and experimentally. With 350 696 potential isomers, the structural space of these assemblies is vast. Orientational self-sorting refe ...

Ligand Effects in Low-Valent Co(I) Clathrochelate Complexes

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Ophélie Marie Planes

Clathrochelate complexes of cobalt are known in the oxidation states I, II, and III. Low-valent Co(I) complexes are highly reactive compounds, and there is only limited knowledge about their structures in the solid state. Herein, we describe the crystallog ...
