The precise control of the molecular position and orientation of its nanoscale assembly on atomic crystals is pivotal for fabricating hybrid organic/inorganic van der Waals heterostructures with targeted function- alities. Recently, we observed the assembly of oleamide into nanoribbons, orienting exclusively along a crystallographic direction on a variety of atomic crystals. Motivated by this observation, we designed a series of long-chain alkanes, alkenes, and their derivatives with -OH, -COOH, and -CONH2 terminal groups to unveil how chemical units regulate the orientation of suparamolecular assembly by density functional theory calculations. We found that the cis-C=C bond can increase the rigidity of long alkyl chains, tailoring angles and van der Waals interactions between them, while the -CONH2 group facilitates intermolecular hydrogen bonds. Either of these two moieties is required for the oriented assembly on both hexagonal and orthorhombic atomic lattices. We predicted that nanoribbons formed by long-chain cis-alkene and derivatives orient along the zigzag direction on graphene and 32 degrees deflected from the armchair direction on black phosphorene, which were supported by the experiment. The fundamental understandings toward the chemical group regulated intermolecular interactions, and their interplay in the oriented supramolecular assembly is expected to substantially expedite the design and controlled synthesis of organic/inorganic van der Waals heterostructures using the bottom-up method.

Sphingolipids are a unique class of lipids owing to their non-glycerol-containing backbone, ceramide, that is constructed from a long-chain aliphatic amino alcohol, sphinganine, to which a fatty acid is attached via an amide bond. Ceramide plays a star role in the initiation of apoptosis by virtue of its interactions with mitochondria, a control point for a downstream array of signaling cascades culminating in apoptosis. Many pathways converge on mitochondria to elicit mitochondrial outer membrane permeabilization (MOMP), a step that corrupts bioenergetic service. Although much is known regarding ceramides interaction with mitochondria and the ensuing cell signal transduction cascades, how ceramide impacts the elements of mitochondrial bioenergetic function is poorly understood. The objective of this review is to introduce the reader to sphingolipid metabolism, present a snapshot of mitochondrial respiration, elaborate on ceramides convergence on mitochondria and the upstream players that collaborate to elicit MOMP, and introduce a mitochondrial phenotyping platform that can be of utility in dissecting the fine-points of ceramide impact on cellular bioenergetics.

The first example of manganese-catalyzed C-alkylation of the carboxylic acid derivatives is reported. The bench-stable homogeneous manganese complex enables the transformation of the renewable alcohol and carboxylic acid derivative feedstock to higher value esters and amides. The reaction operates via hydrogen autotransfer and ideally produces water as the only side product. Importantly, aliphatic-, benzylic-, and heterocyclic-containing alcohols can be used as alkylating reagents, eliminating the need for mutagenic alkyl halides.

AimTo evaluate the remineralization ability of two endodontic sealer cements. MethodologyMid-coronal dentine surfaces were subjected to: (i) 37% phosphoric acid (PA) or (ii) 0.5mol L-1 ethylenediaminetetraacetic acid (EDTA) conditioning prior to the application of two experimental hydroxyapatite-based cements, containing sodium hydroxide (calcypatite) or zinc oxide oxiapatite respectively. Samples were stored in simulated body fluid for 24h or 21days. Remineralization of the dentine surfaces were studied by Raman spectroscopy (mapping with K-means cluster and hierarchical cluster analysis) was undertaken. Nanoroughness and collagen fibril width measurements were performed with an atomic force microscopy. ANOVA and Student-Newman-Keuls test were performed (=0.05). ResultsPhosphoric acid+oxiapatite promoted both the highest dentine mineralization (P<0.05) and crystallographic maturity at the dentine surface. Noncrystalline amorphous-like apatites were also formed. Dentine treated with PA+calcypatite attained the roughest surface (P<0.05) with minimal fibril width (P<0.05). Cross-linking of collagen only became greater in the group PA+oxiapatite after 21days. The maximum relative mineral concentration and structure of collagen linked to the amide I and ratio amide III/AGEs was obtained after using PA+calcypatite at 21-days time-point (P<0.05). EDTA produced a lower stoichiometric hydroxyapatite (P<0.05) with decreased maturity, at the expense of carbonate band widening, although it favoured the nucleation of carbonated calcium phosphate. ConclusionsDentine surfaces treated with PA+oxiapatite attained the highest dentine remineralization with both crystalline-stoichiometric and amorphous apatites, at 21days. EDTA conditioning facilitated amorphous-bulk mineral precipitation. The amorphization was more intense after using oxiapatite and provided an ion-rich environment favouring insitu dentine remineralization.

To seek more efficient and lower toxicity anticancer compounds, several imidazole combining dehydroabietylamine derivatives including organic salts (L-1-L-2) and amides (L-3-L-5) were synthesized. Their antineoplastic activity against HeLa (cervix), MCF-7 (breast), A549 (lung) and HepG2 (liver) cells and HUVECs (umbilical vein, normal cells) in vitro were evaluated by MTT assay. The results unequivocally showed that nearly all compounds had better antineoplastic activity and lower toxicity than dehydroabietylamine (L-0). For MCF-7 cells, L-2 (0.75 M) and L-5 (2.17 M) had higher anti-MCF-7 activity than L-0 and DOX. For A549 cells, L-1 (1.85 M) and L-2 (4.37 M) had higher anti-A549 activity than L-0; in particular, the IC50 value of L-1 was much lower than that of DOX. Among these investigated compounds, L-2 and L-5 had lower IC50 values (0.75 M and 2.17 M) against MCF-7 cells and lower toxicity, which suggested that they may be potential future anticancer drugs. In addition, L-1 and L-2 could suppress cancer cell proliferation by inducing apoptosis. L-1-L-5 could bind with DNA through intercalation.

The enantioselective functionalization of nonactivated enantiotopic secondary C-H bonds is one of the greatest challenges in transition-metal-catalyzed C-H activation proceeding by an inner-sphere mechanism. Such reactions have remained elusive within the realm of Pd-0 catalysis. Reported here is the unique reactivity profile of the IBiox ligand family in the Pd-0-catalyzed intramolecular arylation of such nonactivated secondary C-H bonds. Chiral C-2-symmetric IBiox ligands led to high enantioselectivities for a broad range of valuable indane products containing a tertiary stereocenter, as well as the arylation of secondary C-H bonds adjacent to amides. Depending on the amide substituents and upon control of reaction time, indanes containing labile tertiary stereocenters were also obtained with high enantioselectivities. Analysis of the steric maps of the IBiox ligands indicated that the level of enantioselectivity correlates with the difference between the two most occupied and the two less occupied space quadrants, and provided a blueprint for the design of even more efficient ligands.

Lithium-ion batteries have become ubiquitous to modern life because of their use in the energy storage needs of our daily lives. In past several decades, much effort has been put into studying the molecular structure of electrolytes composed of organic carbonates. However, other solvents with similar properties but better thermal stabilities, such as tertiary amides, have not received the same level of scrutiny. In this work, solutions of lithium salts in ureas, tertiary amides with the structure RR’N-CO-NR ” R”’, with different sizes and connectivity are studied. Ureas present an interesting case study because unlike organic carbonates, the amide bond is planar and has restricted conformational change. In addition, ureas cannot bind the lithium ion through their nitrogen atoms. By using steady-state and time-resolved infrared spectroscopies and ab-initio computational methods, detailed descriptions of the changes to the lithium-ion solvation structure as a result of the urea structure were derived for three ureas bearing a strong resemblance to commonly used organic carbonates. These results show that the solvation shell of ureas has a tetrahedral structure similar to that of other organic solvents. Although the structure of the amide bonds in these ureas is similar to that of carbonate molecules, the atomic connectivity differs. In addition, the dynamics of the cation solvation shell formed by ureas shows a picosecond motion, which is attributed to deformation of the tetrahedral structure. Our investigations also indicate that the deformation dynamics is controlled directly by the size of the urea because of the rigidity of the amide bond in these molecules. Overall, this work shows that ureas share similarity with their organic carbonate analogues, but the rigid urea structure provides an easier framework for interpreting the vibrational observations in terms of the solvent molecular structure.

Maps that relate spectroscopic properties of a vibrational mode and collective solvent coordinates have proven useful in theoretical vibrational spectroscopy of condensed-phase systems. It has been realized that the predictive power of such an approach is limited and there is no clear systematic way to improve its accuracy. Here, we propose an adaptation of Delta-machine-learning methodology that goes beyond the spectroscopic maps. The machine-learning part of our approach combines Gaussian process regression used to generate the data set with an artificial neural network used to predict spectroscopic properties of interest. A specific application to the OH-stretch frequencies and transition dipoles of water is presented. Our method approximates these properties about two times more accurately than the spectroscopic-maps-only-based approach. Our results become useful in the study of vibrational spectroscopy of condensed-phase systems.

Soluble epoxide hydrolase (sEH) is an alpha/beta hydrolase fold protein and widely distributed in numerous organs including the liver, kidney, and brain. The inhibition of sEH can effectively maintain endogenous epoxyeicosatrienoic acids (EETs) levels and reduce dihydroxyeicosatrienoic acids (DHETs) levels, resulting in therapeutic potentials for cardiovascular, central nervous system, and metabolic diseases. Therefore, since the beginning of this century, the development of sEH inhibitors is a hot research topic. A variety of potent sEH inhibitors have been developed by chemical synthesis or isolated from natural sources. In this review, we mainly summarized the interconnected aspects of sEH with cardiovascular, central nervous system, and metabolic diseases and then focus on representative inhibitors, which would provide some useful guidance for the future development of potential sEH inhibitors.

Designing porous and functionalized adsorbents and achieving high efficiency in heavy metals removal from wastewater is in the spotlight of environmental science. On the other hand, upon removal, adsorbents are still highly hazardous requiring that great care be taken in its packaging, transporting and storing. A fundamental route in the synthesis of functional extended structures is the ability to combine different chemical entities in a controlled way in order to achieve high performance. Herein, we report the systematic design of dualfunctionalized metal organic framework (TMU-81) by incorporating sulfonyl and amide groups for the removal of Cd(II), Cu(II) and Cr(II) ions from simulated aqueous solutions. TMU-81 showed significant enhancement in heavy metals uptake suggesting that the strong host guest interactions between cations and the donor sites play a major role in adsorption process. The maximum adsorption capacity for Cd2+ was 526 mg/ g which is among the highest values reported for similar MOFs and other porous materials. The good performance in uptake and selectivity of TMU-81 can be attributed to the network structure that shaping the void, create mono-dimensional channels, decorated by exposed oxygen atom sites selective for Cadmium ion. Environmental compatibility of a treated MOFs was studied in order to evaluate its possible recycling as a new template for different applications by using pyrolysis method. Engineering of the pore surface provides a potential for MOF with a hybrid interface to act as a versatile tool for the design of multifunctional nanoparticles to meet specific application requirements.
