Nanoscopy with Focused Light (Nobel Lecture)

Nanoscopy with Focused Light (Nobel Lecture)

A picture is worth a thousand words—This doesn't only apply to everyday life but also to the natural sciences. It is, therefore, probably not by chance that the historical beginning of modern natural sciences very much coincides with the invention of light microscopy. S. W. Hell shows in his Nobel Lecture that the diffraction resolution barrier has been overcome by using molecular state transitions (e.g. on/off) to make nearby molecules transiently discernible.

Computer-Aided Design of Ionic Liquids as CO2 Absorbents

Computer-Aided Design of Ionic Liquids as CO2 Absorbents

Better by design: Using a continuum model makes it possible to distinguish between the chemical and physical absorption of CO2 in ionic liquids. The ionic liquids showing chemical adsorption were further narrowed down to “good” candidates, in which a facile desorption is feasible according to a calculated energy criterion. This criterion was determined by correlating the calculated Gibbs free energies with experimental capacities.

Synthesis, Characterization, and Memory Performance of Two Phenazine/Triphenylamine‐Based Organic Small Molecules through Donor‐Acceptor Design

Synthesis, Characterization, and Memory Performance of Two Phenazine/Triphenylamine‐Based Organic Small Molecules through Donor‐Acceptor Design

Test your memory: Two organic small molecules TPA-2BIPs and TPA-3BIPs have been synthesized and characterized. Sandwich-structure memory devices made from these molecules show that the two materials have similar switching behavior but different ON/OFF ratios. AFM images analysis and molecular simulation indicate that increasing the numbers of acceptors change the stacking of molecules in the solid state, but have less effect on switching behaviors of as-prepared memory devices.

How the [NiFe4S4] Cluster of CO Dehydrogenase Activates CO2 and NCO

How the [NiFe4S4] Cluster of CO Dehydrogenase Activates CO2 and NCO−

Two sides of the same coin: CO2 and NCO are both activated at Ni and Fe2 of the [NiFe4S4] cluster of CO dehydrogenase and bind as bridging ligands between the two metal atoms. Insights from true atomic resolution structures draw a clear picture of the chemical nature of the ligands: activation of both the substrate CO2 and the inhibitor NCO occurs by formal two-electron reduction.

Synthesis of a Tricyclic Bisguanidine Compound Structurally Related to Saxitoxin and its Identification in Paralytic Shellfish Toxin-Producing Microorganisms

Synthesis of a Tricyclic Bisguanidine Compound Structurally Related to Saxitoxin and its Identification in Paralytic Shellfish Toxin-Producing Microorganisms

You know that you're toxic: Direct conversion of Int-C'2, a biosynthetic intermediate of saxitoxin (STX), into a tricyclic bisguanidine compound (Cyclic-C'), which is structurally related to STX, was achieved through oxidative cyclization catalyzed by Pd/C under basic conditions in air (see scheme). By using HPLC-MS analysis, Cyclic-C' was also identified in the paralytic shellfish toxin (PST)-producing microorganisms, suggesting that Cyclic-C' is involved in biosynthesis of PSTs.

Indolo[3,2-c]quinoline G-Quadruplex Stabilizers: a Structural Analysis of Binding to the Human Telomeric G-Quadruplex

A much higher IQ: We report indolo[3,2-c]quinoline (IQc) derivatives with two weak basic side chains as potent and selective human telomeric (HT) G-quadruplex (G4) stabilizers. Biophysical data show that stabilization involves the binding of two ligands which induces a conformational rearrangement of the HT G4 structure. Moreover, selected derivatives showed selective antiproliferative activity toward human malignant cell lines.

Solvent-Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

Solvent-Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

Super phenolic solvents: Biomass-derived carbohydrates represent an attractive source of renewable carbon due to their many chemical and biological conversion routes to fuels and chemicals. In a nonenzymatic biomass deconstruction process for producing carbohydrates, separating a mixture of γ-valerolactone (GVL) and water used in the process is a key step. We demonstrate that phenolic solvents are highly effective at separating GVL and can be used to detoxify the biomass-derived mixture for fermentation.

Chiral Chlorohydrins from the Biocatalyzed Reduction of Chloroketones: Chiral Building Blocks for Antiretroviral Drugs

Chiral Chlorohydrins from the Biocatalyzed Reduction of Chloroketones: Chiral Building Blocks for Antiretroviral Drugs

Choose your side, not your enzyme: A single alcohol dehydrogenase is able to reduce structurally related chloroketones derived from S-amino acids with the opposite enantiopreference to furnish both (R,S) and (S,S)-chlorohydrins. Stereocontrol is achieved by changing the N-protecting group in the substrate, which allows the preparation of stereocomplementary halohydrins using the same biocatalyst.

Regulating the Coordination State of a Heme Protein by a Designed Distal Hydrogen‐Bonding Network

Regulating the Coordination State of a Heme Protein by a Designed Distal Hydrogen‐Bonding Network

Fine-tuning heme proteins: Heme coordination state determines the functional diversity of heme proteins. We introduced distal glutamic acid (Glu29) and histidine (His43) residues in myoglobin and regulated the heme into a non-native bis-His coordination state with native ligands His64 and His93, resembling natural globins such as cytoglobin and neuroglobin. This new approach can be generally applied for fine-tuning the structure and function of heme proteins.
