Tramadol—A True Natural Product?

Tramadol—A True Natural Product?

The root of the problem: Tramadol, a synthetic analgesic, was recently detected in the roots of the Cameroonian medicinal plant Nauclea latifolia. However, tramadol is not a natural product. Along with its major mammalian metabolites, tramadol is present in the roots of N. latifolia and other plant species, as well as in soil and local water sources in the Far North region of Cameroon as a result of anthropogenic contamination.

Solvent Effects in Acid-Catalyzed Biomass Conversion Reactions

Solvent Effects in Acid-Catalyzed Biomass Conversion Reactions

In acid-catalyzed biomass conversion (e.g., dehydration of xylose to furfural), the use of polar aprotic organic solvents, such as γ-valerolactone, affects the stabilization of the acidic proton relative to the protonated transition states. This leads to accelerated reaction rates and increased product selectivities compared to the transformations in aqueous media.

Properties and Reactivity of Conformationally Constrained Bicyclic Diarylprolinol Silyl Ethers as Organocatalysts

Properties and Reactivity of Conformationally Constrained Bicyclic Diarylprolinol Silyl Ethers as Organocatalysts

Bicyclic silyl ether derivative 1a, which is easily prepared from trans-4-L-hydroxyproline, is much more stable toward protodesilylation than Jørgensen–Hayashi's catalyst 2a. Despite their structural analogy, 1a behaves as a very efficient catalyst in iminium chemistry, but is much less active than 2a in the enamine activation mode. Here, 1a exhibits a higher or equivalent level of stereocontrol.

Methanol Steam Reforming Promoted by Molten Salt-Modified Platinum on Alumina Catalysts

Methanol Steam Reforming Promoted by Molten Salt-Modified Platinum on Alumina Catalysts

Molten salts might have a new life: Platinum-on-alumina catalysts are boosted in their selectivity and activity for methanol steam reforming by a surface coating with basic and hygroscopic alkali salts. As evidenced by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and temperature-programmed desorption (TPD) studies, alkali doping through the salt coating is an important factor for this enhanced performance.

A Combinatorial Approach towards Water-Stable Metal–Organic Frameworks for Highly Efficient Carbon Dioxide Separation

A Combinatorial Approach towards Water-Stable Metal–Organic Frameworks for Highly Efficient Carbon Dioxide Separation

With our powers combined: A library of 20 UiO-66-derived metal–organic frameworks (MOFs) is synthesized following a combinatorial approach involving mixed ligand copolymerization and two post-synthetic modifications in tandem. The MOFs have excellent water stabilities in a pH range of 1 to 12 together with high carbon dioxide (CO2) uptake capacities and selectivities. These features make them promising adsorbents in adsorption-based CO2 separations such as post-combustion CO2 capture and upgrading natural gas.

Cluster Size Effects of Platinum Oxide as Active Sites in Hydrogen Evolution Reactions

Cluster Size Effects of Platinum Oxide as Active Sites in Hydrogen Evolution Reactions

Photolysis of water for “green” hydrogen production was studied, for the first time, as a function of the size of oxidized platinum clusters as active sites (the light spots in each square in the figure). The maximum hydrogen evolution rate is found on the smallest-sized clusters. This effect can be attributed to the size-dependent free-energy change of proton adsorption of the clusters with respect to desorption of hydrogen molecules.

O6-Alkylguanine-DNA Alkyltransferase-Mediated Repair of O4-Alkylated 2'-Deoxyuridines

In need of repair: O6-Alkylguanine-DNA alkyltransferases (AGTs) remove O6-alkyl 2'-deoxyguanosine and O4-alkyl thymidine adducts from the genome. Unlike the E. coli OGT (O6-alkylguanine-DNA alkyltransferase), human AGT only removes methyl groups from the O4 atom of thymidine poorly. The C5 methyl group of thymidine affects AGT repair, as was revealed by experiments with oligonucleotides containing O4-alkyl 2'-deoxyuridines.

Importance of the 6'-Hydroxy Group and Its Configuration for Apramycin Activity

Importance of the 6'-Hydroxy Group and Its Configuration for Apramycin Activity

Inversion of configuration of the 6'-OH group of apramycin moderates the antiribosomal and antibacterial activities of this aminoglycoside antibiotic. Deletion of the 6'-OH group diminishes all activity substantially, and its replacement by an amino group is detrimental to activity. These results are consistent with apramycin adopting the standard binding mode of the 4,5- and 4,6-aminoglycosides in the decoding A-site of the bacterial ribosome as opposed to the alternative binding mode proposed in some studies.

Seed-Mediated Synthesis of Gold Tetrahedra in High Purity and with Tunable, Well-Controlled Sizes

Seed-Mediated Synthesis of Gold Tetrahedra in High Purity and with Tunable, Well-Controlled Sizes

Nothing ever grows without a seed: Gold tetrahedra with well-controlled sizes in the range of 30–60 nm were synthesized in high yield using seed-mediated growth. We also monitored the evolution of shape from spherical seeds 10 nm in size to the tetrahedra. For the first time, Au nanocrystals with a tetrahedral shape could be obtained with an edge length as short as 30 nm.

Remarkable Shape-Sustaining, Load-Bearing, and Self-Healing Properties Displayed by a Supramolecular Gel Derived from a Bis-pyridyl-bis-amide of L-Phenyl Alanine

Remarkable Shape-Sustaining, Load-Bearing, and Self-Healing Properties Displayed by a Supramolecular Gel Derived from a Bis-pyridyl-bis-amide of l-Phenyl Alanine

Healing is a matter of time: A series of bis-amides derived from L-phenylalanine and L-alanine displayed moderate to good gelation ability with various solvents. Structure–property correlation using single-crystal and powder X-ray diffraction on selected gels was attempted. One of the gelator resulted in a gel with outstanding load-bearing and self-healing properties. The 1,2-dichlorobenzene gel of this gelator was so strong that letters could be carved into a thin slice of the gel.

Detailed Geometric and Electronic Structures of a One-Electron-Oxidized Ni Salophen Complex and Its Amido Derivatives

Detailed Geometric and Electronic Structures of a One-Electron-Oxidized Ni Salophen Complex and Its Amido Derivatives

The radical complexes depicted feature a near-IR (NIR) transition. Time-dependent DFT (TD-DFT) calculations reveal that its origin differs and strongly depends on the linker between the central ring and the phenol rings. Depending on the linker, it is an intervalence charge transfer (IVCT) transition, an intraligand charge transfer (LLCT), or acquires ligand-to-metal charge transfer (LMCT) character.
