Now introduce a scientific discovery about this category.

This study deals with removal of phenolic compounds from water by perstraction, and poly(ether-b-amide) (PEBA) membranes were selected because of their excellent permeability to phenolics. The permeability, diffusivity and solubility of model phenolic compounds (including the simplest phenol (PhOH), 4-methylphenol (MePhOH), 4-nitrophenol (O2NPhOH) and 4-chlorophenol (ClPhOH)) in the membrane were investigated. The membrane showed a permeability in the order of ClPhOH > MePhOH > O2NPhOH > PhOH, while the diffusivity followed the order of PhOH > MePhOH > O2NPhOH > ClPhOH. Based on the resistance-in-series model, the mass transfer characteristics of the liquid/membrane/liquid perstraction system was analyzed, and the individual mass transfer resistances from the various steps of the perstraction process were estimated. It was revealed that the membrane resistance was significant, and the mass transfer resistance at the downstream side of the membrane as a result of phenol desorption from the membrane and boundary layer effects was not negligible. While the strong affinity between PEBA and phenolics was responsible for the good phenol permeability in the membrane, it also resulted in a high resistance to phenol desorption from the membrane. The use of an alkaline stripping agent can effectively enhance phenol removal from water by reducing the mass transfer resistances of the liquid boundary layers and phenol desorption at the downstream side of the membrane. For a given phenolic compound, the enhancement in mass transfer rate was affected by the alkaline concentration, and the enhancement was particularly significant when thin membranes were used.

Antigenic fractions of 100, 50, 37, and 28 kDa obtained through the SDS-PAGE method that were more frequently recognized by anti-Coccidioides antibodies in the sera of coccidioidomycosis patients were selected using western blotting. Subsequently, these bands were sequenced, and the obtained proteins were analysed by BLAST to choose peptides specific for Coccidioides spp. from among the shared aligned sequences of related fungi. A peptide specific for C. immitis was selected from the GPI anchored serine-threonine rich protein OS C. immitis, while from the uncharacterized protein of C. immitis, we selected a peptide for C. immitis and C. posadasii. These proteins arose from the 100 kDa antigenic fraction. From the protein fatty acid amide hydrolase 1 of C. posadasii that was identified from the 50 kDa antigenic fraction, a peptide was selected that recognized C. immitis and C. posadasii. In addition, the analysis of all the peptides (353) of each of the assembled proteins showed that only 35 had 100% identity with proteins of C. immitis and C. posadasii, one had 100% identity with only C. immitis, and one had 100% identity with only C. posadasii. These peptides can be used as diagnostic reagents, vaccines, and antifungals.

The first example of a ruthenium-catalyzed C-H bond alkylation via six-membered ruthenacycles is presented. This is disclosed for the C-H bond alkylation of biologically relevant cyclic amides with maleimide derivatives. The cyclic tertiary amide core acted as a directing group (DG) enabling formation of six-membered cycloruthenated species responsible for the control of the regio- and site selectivity of the reaction as well as the excellent functional group tolerance. Unexpectedly, cyclic amides were found to be better DGs than pyridine-containing ones or cyclic imides for this type of C-H bond functionalization.

Design and Synthesis of Bioisosteres of Acylhydrazones as Stable Inhibitors of the Aspartic Protease Endothiapepsin

Acylhydrazone-based dynamic combinatorial chemistry (DCC) is a powerful strategy for the rapid identification of novel hits. Even though acylhydrazones are important structural motifs in medicinal chemistry, their further progression in development may be hampered by major instability and potential toxicity under physiological conditions. It is therefore of paramount importance to identify stable replacements for acylhydrazone linkers. Herein, we present the first report on the design and synthesis of stable bioisosteres of acylhydrazone-based inhibitors of the aspartic protease endothiapepsin as a follow-up to a DCC study. The most successful bioisostere is equipotent, bears an amide linker, and we confirmed its binding mode by X-ray crystallography. Having some validated bioisosteres of acylhydrazones readily available might accelerate hit-to-lead optimization in future acylhydrazone-based DCC projects.

Hydride Amide and Hydride Phenolate Complexes of NHC Coordinated Aluminum

The reaction of NHC alane adducts NHC center dot AlH3 (NHC = N-Heterocyclic Carbene; NHC = iPr(2)Im, Dipp(2)Im; R(2)Im = 1,3-di-organyl-imidazolin-2-ylidene; iPr = isopropyl; Dipp = 2,6-diisopropylphenyl) with secondary amines HNR2 [R = iPr, Ph, Si(CH3)(3)] and the reaction of the trimethylamine alane adduct (NMe3)center dot AlH3 with secondary amines followed by the reaction with the NHC both lead to formation of the compounds NHC center dot AlH2(NR2) 1-6 [NHC = iPr(2)Im, Dipp(2)Im, R = iPr, Ph, Si(CH3)(3)]. These compounds are stable in solution up to temperatures of 90 degrees C. In contrast to the NHC alane adduct (iPr(2)Im)center dot AlH3 (I) and (Dipp(2)Im)center dot AlH3 (II), no ring expansion reaction to six-membered heterocyclic rings or ring opening reaction were observed for the reaction of (iPr(2)Im)center dot AlH2(NR2) with another equivalent of the NHCs iPr(2)Im or Dipp(2)Im. Thus, amide substituted NHC alane adducts show a much high stability compared to the parent compounds NHC center dot AlH3. Furthermore, the reaction of NHC center dot AlH3 (NHC = iPr(2)Im, Dipp(2)Im) with 2,4,6-trimethylphenol leads to the formation of the adducts NHC center dot AlH3-n(OMes)(n) 7-10 (n = 1, 2). The reaction with n >= 3 equivalent of 2,4,6-trimethylphenol afforded the imidazolium salt [Dipp(2)ImH](+)[Al(OMes)(4)](-) (11). The compounds 7-11 are also stable with respect to ring expansion after addition of another equivalent NHC.

Hydrogen bond donor functionalized dioxido-molybdenum(VI) complexes as robust and highly efficient precatalysts for alkene epoxidation

The synthesis of four novel, tridentate aminophenolate ligands HL1-HL4, bearing amide functionalities is reported. Reaction of these ligands with a dioxido molybdenum(VI) precursor led, depending on the choice of solvent, to mononuclear complexes of the type [MoO2L(OMe)] (2, 4, 6) or dinuclear complexes [{MoO2L}(2)(mu-O)] (1, 3, 5, 7), containing one facially, tridentate ONO-ligand per metal center. This synthetic discrimination between dinuclear and mononuclear complexes allows for a comparison between structures and reactivity. Complexes 1-7 were found to be highly active catalysts in the epoxidation of several internal and terminal alkenes. With tent-butyl hydroperoxide (TBHP) as oxidant, precatalyst loadings of 0.0005 mol% (5 ppm) could be realized leading to turnover numbers of up to 110000. The pre-catalysts also allowed for the use of hydrogen peroxide (0.1 mol% precatalyst) as oxidant as well as various alcohols as green solvents, such as ethanol or even tert-butanol (usually an inhibitor of epoxidation).

The endocannabinoid system: Novel targets for treating cancer induced bone pain

Treating Cancer-induced bone pain (CIBP) continues to be a major clinical challenge and underlying mechanisms of CIBP remain unclear. Recently, emerging body of evidence suggested the endocannabinoid system (ECS) may play essential roles in CIBP. Here, we summarized the current understanding of the antinociceptive mechanisms of endocannabinoids in CIBP and discussed the beneficial effects of endocannabinoid for CIBP treatment. Targeting nonselective cannabinoid 1 receptors or selective cannabinoid 2 receptors, and modulation of peripheral AEA and 2-AG, as well as the inhibition the function of fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) have produced analgesic effects in animal models of CIBP. Management of ECS therefore appears to be a promising way for the treatment of CIBP in terms of efficacy and safety. Further clinical studies are encouraged to confirm the possible translation to humans of the very promising results already obtained in the preclinical studies.

N-Annulated perylene-based organic dyes sensitized graphitic carbon nitride to form an amide bond for efficient photocatalytic hydrogen production under visible-light irradiation

In this work, two new N-annulated perylene-based organic sensitizers (PY-1 and PY-2) have been developed for dye-sensitized graphitic carbon nitride (g-C3N4) to remarkably enhance photocatalytic hydrogen production under visible-light irradiation (420 nm <= lambda <= 780 nm). The results showed that the H-2 production rates of the PY-1/g-C3N4/Pt and PY-2/g-C3N4/Pt were up to 5508.1 mu mol h(-1) g(-1) and 11,855.4 mu mol h(-1) g(-1) respectively, which were 8.98 and 19.3 times higher than that of the g-C3N4/Pt, respectively. Specifically, an impressive record apparent quantum efficiency (AQY) of 27.16% for PY-2/g-C3N4/Pt system was achieved at lambda = 550 nm monochromatic light irradiation. Moreover, the formation of amide bonds between dye molecules and g-C3N4 was firstly confirmed by FTIR spectrum and theoretical calculation. The amide bonds provided the electron transfer channels to significantly improve interface charge transfer and separation, thus resulting in a more efficient hydrogen production. More importantly, PY-1/g-C3N4/Pt and PY-2/g-C3N4/Pt displayed good stability under long-term irradiation and was favorable and significant for practical application. Our work indicated that dye sensitized g-C3N4 to form an amide bond is a promising strategy to realize the effective conversion of solar energy to hydrogen energy through molecular engineering.

Inorganic-Organic Hybrid Photomechanical Crystals Consisting of Diarylethenes and Cage Siloxanes

Photomechanical materials have received increasing attention because of their wide range of potential applications. This paper reports the design of photoresponsive inorganic-organic hybrid molecules consisting of diarylethene and polyhedral oligomeric silsesquioxane (POSS) linked by amide bonds. The POSS modification of diarylethene enhanced the conversion ratio from the open- to the closed-ring isomers upon UV irradiation in a solution. When isobutyl-substituted POSSs were introduced, hydrogen-bonded molecular crystals with a long needle-like morphology were obtained. Reversible photochromic responses and photoinduced macroscopic bending of these crystals upon ultraviolet (UV) and visible light (Vis) irradiations have been achieved. The high fatigue resistance of the diarylethene moiety combined with enhanced thermal stability endowed by the siloxane moiety is promising for practical applications in actuators and other smart devices.

Protein NMR Resonance Assignment without Spectral Analysis: 5D SOlid-State Automated Projection SpectroscopY (SO-APSY)

Narrow proton signals, high sensitivity, and efficient coherence transfers provided by fast magic-angle spinning at high magnetic fields make automated projection spectroscopy feasible for the solid-state NMR analysis of proteins. We present the first ultrahigh dimensional implementation of this approach, where 5D peak lists are reconstructed from a number of 2D projections for protein samples of different molecular sizes and aggregation states, which show limited dispersion of chemical shifts or inhomogeneous broadenings. The resulting datasets are particularly suitable to automated analysis and yield rapid and unbiased assignments of backbone resonances.
