Melaminium hydrogen malonate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 The melaminium (2,4,6-triamino-1,3,5-triazin-1-ium) cation in the title compound, C3H7N6+·C3H3O4−, is essentially planar, with a r.m.s. deviation of the non-H atoms of 0.0085 Å. Extensive hydrogen bonding of the types N—H...N and N—H...O between cations and cations and between cations and hydrogen malonate (2-carboxyethanoate) anions leads to the ...

Structurally Defined Water‐Soluble Metallofullerene Derivatives towards Biomedical Applications
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 A modular metallobuckytrio (MBT) platform provides a family of structurally defined, water‐soluble metallofullerene derivatives that can safely carry rare‐earth elements in tailorable molecules, showing promise in biomedicines including MRI contrast agents and photosensitizers. Abstract Endohedral metallofullerenes (EMFs) are excellent carriers of rare‐

Time‐resolved multiparameter analytics on a cell‐free production platform for acyl‐CoA precursors
Analytical Science Advances, Volume 3, Issue 11-12, Page 289-296, December 2022., 2022 Abstract Cell‐free biosynthesis is emerging as a very attractive alternative for the production of market‐relevant molecules. The free combination of enzymes, regardless of where they are isolated from, raises the possibility to build more efficient synthetic routes but at the same time leads to higher complexity regarding the analysis of the different

Supramolecular Gels as Active Tools for Reaction Engineering
Angewandte Chemie, EarlyView.The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Angewandte Chemie, EarlyView.Benzamide‐directed iridium‐catalyzed branched selective and enantioselective C(sp2)‐H additions to minimally activated alkenes give tertiary and quaternary benzylic stereocenters under byproduct‐free conditions. The processes are enabled by a family of SPINOL‐based homochiral diphosphonite ligands.

Gem‐Diboronic Acids: A Motif for Anion Recognition in Competitive Media
Angewandte Chemie, EarlyView.Gem‐diboronic acids are an anion recognition motif that provides strong and directional binding to oxoanions in aqueous media. This motif provides a selectivity profile that is distinct from other anion recognition groups, and binding affinities that are superior to those of simple amides and (thio)ureas.

Angewandte Chemie, EarlyView.The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Regulating Protein Immobilization During Cell‐Free Protein Synthesis in Hyaluronan Microgels
Advanced Biology, EarlyView.Bifunctional microgels carrying a linear DNA template and Ni2+‐activated NTA moieties are used as platform for cell‐free protein synthesis and in situ protein immobilization. By varying the concentration of NTA moieties in the microgels, the amount of GFP‐His immobilized inside the microgel and released to the microgel environment can be regulated ...
