Summary: Artificial metalloenzymes (ArMs) were engineered to catalyze diazo cross-coupling resulting in high enantioselectivity alkene reduction to alkane in a one-pot cascade reaction. Directed evolution improved reaction yields and selectivities for various substrates. Molecular dynamics simulations of ArM variants were used to understand the structural role of the cofactor on ArM conformational dynamics, highlighting the ability of ArMs to control both catalyst stereoselectivity and chemoselectivity in complex media.

Summary: Active sites within catalysts play a crucial role in driving reactions and catalysis. By spatially confining guest metals in the microenvironments of active sites, the catalytic activity can be improved by modifying the electronic states of the active sites. In this study, the intercalation of zinc single atoms between layers of 1T-MoS2 enhances the performance of the hydrogen evolution reaction (HER) by reducing overpotential, charge transfer resistance, and kinetic barrier. This enhancement is achieved by controlling the coordination geometry and electronic states of the confined zinc atoms, which donate electrons to coordinated sulfur atoms and improve HER kinetics.

Summary: This study presents a photoenzymatic intermolecular hydroalkylation of olefins catalyzed by flavin-dependent 'ene'-reductases. A unique mechanism involving a charge-transfer complex formed between an alkene, alpha-chloroamide, and flavin hydroquinone ensures radical formation only occurs when both substrates are present within the protein active site. This work demonstrates the potential for new biocatalytic transformations enabled by photoenzymatic catalysis through previously unknown electron transfer mechanisms.

Summary: This study investigates the reversible oxidation of formate to carbon dioxide catalyzed by molybdenum or tungsten-containing formate dehydrogenases. The formation of bicarbonate as the first intermediate during the reaction at the active site is discovered, contrary to previous reports. Bicarbonate formation occurs after an oxygen atom transfer reaction, where the oxygen is transferred from water to formate, followed by a proton-coupled electron transfer or hydride transfer reaction involving the sulfido ligand as the acceptor.

Summary: We developed a new method for synthesizing different quinodimethane derivatives by oxidizing bis-N-heterocyclic olefins linked by pi-conjugated aromatic spacers. Stable diimidazolium para- and ortho-quinodimethane derivatives were obtained with para- and ortho-phenylene bridges, as well as with tetrafluoro-p-phenylene and p-anthracene spacers. The influence of imidazolium substituents on the air and moisture stability of the quinodimethane derivatives was emphasized. Different electron transfer processes were observed depending on the pi-conjugated aromatic spacer used, with two one-electron or one two-electron redox transitions between bis-N-heterocyclic olefins and diimidazolium-quinodimethanes. The formation of pi-conjugated radical-cations, which are transient redox intermediates, was confirmed by EPR investigation.

Summary: Several synthetic cross-coupling procedures were evaluated for tethering pyrazine to dithiocarbonates. The resulting compounds can serve as pro-ligands and can be converted into ene-dithiolate ligand systems resembling molybdopterin by removing the C=O moiety. The coupling of 2-iodopyrazine with stannylated dithiocarbonate units mediated by copper(I)-thiophene-2-carboxylate in stoichiometric equivalents proved to be the most efficient and reliable method for synthesizing the targeted compounds.

Summary: In recent years, the biological properties of pentathiepins have gained attention for their potential in cancer treatment. However, their low solubility and stability limitations have hindered biological evaluation. This study investigated the use of liposomes as drug carriers for pentathiepins to improve solubility and stability. The results showed that the aqueous solubility of pentathiepins increased significantly when incorporated into liposomes, and the stability of pentathiepins in the presence of the antioxidant glutathione was enhanced. Moreover, the liposomal loaded pentathiepins demonstrated comparable anticancer activity to free pentathiepins. In conclusion, liposomes are a suitable carrier for pentathiepins and can improve their solubility and stability without compromising their anticancer activity.

Summary: Heteroleptic molybdenum complexes with P2N2 and non-innocent dithiolene ligands were synthesized and electrochemically characterized. The reduction potentials of the complexes were adjusted by ligand-ligand cooperativity via non-covalent interactions. This finding was supported by electrochemical studies, UV/Vis spectroscopy, and temperature-dependent NMR spectroscopy. The observed behavior resembles enzymatic redox modulation through second ligand sphere effects.

Summary: The reduction of 2-H-substituted pyrrolinium cations results in dimerisation or H-abstracted products, depending on the N-substituents. The dimerised 2,2'-bipyrrolidine derivatives with a central carbon-carbon single bond are stable and can be oxidised chemically or electrochemically. These dimers, which are air and moisture-stable, can serve as a source of two electrons in various chemical transformations.
