Reversible 1,2-Addition of Water To Form a Nucleophilic Mn(I) Hydroxide Complex: A Thermodynamic and Reactivity Study

((PNP)-P-iPr-P-H)Mn(CO)(2)(OH) (2; (PNP)-P-iPr-P-H = HN{CH2CH2((PPr2)-Pr-i)}(2)) was formed from the reversible 1,2 addition of water to ((PNP)-P-ipr)Mn(CO)(2) (1; (PNP)-P-iPr = the deprotonated, amide form of the ligand, N-{CH2CH2(PiPr(2))}(2)). This reversible reaction was probed via variable-temperature NMR experiments, and the energetics of the 1,2-addition/elimination was found to be slightly exothermic (-0.8 kcal/mol). The corresponding manganese hydroxide was found to react with aldehydes, yielding the corresponding manganese carboxylate complexes ((PNP)-P-iPr-P-H)Mn(CO)(2)(CO2R), where R = H, methyl, phenyl. While no reaction between 1 and neat benzaldehyde was observed, in the presence of water, conversion to the corresponding manganese-bound benzoate with formation of H-2 was observed. The catalytic oxidation of benzaldehyde by water without additives was unsuccessful due to strong product inhibition, with the manganese benzoate formed under a variety of reaction conditions. Upon addition of base, a catalytic cycle for the conversion of aldehyde to carboxylate and hydrogen can be devised.

Comparative study on pyrolytic transformation mechanism of ANFs-derived carbon membrane for electromagnetic interference shielding application

Selecting suitable precursor and exploring controllable carbonization process is crucial to carbon materials, especially for carbon-based material in electromagnetic interference shielding application. However, carbon materials are primarily used in the forms of powders, which remains big challenge in developing continuous ones. Herein, large-scale aramid nanofibers (ANFs)-derived carbon membrane was developed for the first time. Influence of pyrolysis temperature on chemical constitution and crystalline structure during carbonization process was investigated. The results showed that the decomposition stage of ANFs freestanding membrane begun at similar to 474 degrees C, while the reconstruction stage begun at similar to 600 degrees C. Besides, the rupture of amide bonds occurred around 500 degrees C, which was validated by disappearance of C=O groups. Moreover, the declining integrated intensities I-D/I-G,I- and the sharp rising electrical conductivity of demonstrated progressive aromatization and ring condensation. In addition, the microgrooves with an average diameter of similar to 40 nm were formed during the carbonization. Subsequently, the ANFs-derived carbon membrane exhibited superior conductivity (123.8 S cm(-1)) and electromagnetic shielding effectiveness value of 16 dB (X band) with thickness of 28 mu m. This work provided feasible strategy in fabricating carbon-based membrane for advanced electronic devices.

Perinatal maternal high-fat diet induces early obesity and sex-specific alterations of the endocannabinoid system in white and brown adipose tissue of weanling rat offspring

Perinatal maternal high-fat (HF) diet programmes offspring obesity. Obesity is associated with overactivation of the endocannabinoid system (ECS) in adult subjects, but the role of the ECS in the developmental origins of obesity is mostly unknown. The ECS consists of endocannabinoids, cannabinoid receptors (cannabinoid type-1 receptor (CB1) and cannabinoid type-2 receptor (CB2)) and metabolising enzymes. We hypothesised that perinatal maternal HF diet would alter the ECS in a sex-dependent manner in white and brown adipose tissue of rat offspring at weaning in parallel to obesity development. Female rats received standard diet (9 % energy content from fat) or HF diet (29 % energy content from fat) before mating, during pregnancy and lactation. At weaning, male and female offspring were killed for tissue harvest. Maternal HF diet induced early obesity, white adipocyte hypertrophy and increased lipid accumulation in brown adipose tissue associated with sex-specific changes of the ECS’s components in weanling rats. In male pups, maternal HF diet decreased CB1 and CB2 protein in subcutaneous adipose tissue. In female pups, maternal HF diet increased visceral and decreased subcutaneous CB1. In brown adipose tissue, maternal HF diet increased CB1 regardless of pup sex. In addition, maternal HF diet differentially changed oestrogen receptor across the adipose depots in male and female pups. The ECS and oestrogen signalling play an important role in lipogenesis, adipogenesis and thermogenesis, and we observed early changes in their targets in adipose depots of the offspring. The present findings provide insights into the involvement of the ECS in the developmental origins of metabolic disease induced by inadequate maternal nutrition in early life.

Conformation-Specific Spectroscopy of Asparagine-Containing Peptides: Influence of Single and Adjacent Asn Residues on Inherent Conformational Preferences

The infrared and ultraviolet spectra of a series of capped asparagine-containing peptides, Ac-Asn-NHBn, Ac-Ala-Asn-NHBn, and Ac-Asn-Asn-NHBn, have been recorded under jet-cooled conditions in the gas phase in order to probe the influence of the Asn residue, with its -CH2-C(= O)-NH2 side chain, on the local conformational preferences of a peptide backbone. The double-resonance methods of resonant ion-dip infrared (RIDIR) spectroscopy and infrared-ultraviolet hole burning (IR-UV HB) spectroscopy were used to record single conformation spectra in the infrared and ultraviolet, respectively, free from interference from other conformations present in the molecular beam. Ac-Asn-NHBn spreads its population over two conformations, both of which bonds that form a bridge between the Asn carboxamide group and the NH and C = O groups on the peptide backbone. In one the peptide backbone engages in a 7-membered H-bonded ring (labeled C-eq(7)), thereby forming an inverse gamma-turn, stabilized by a C6/C7 Asn bridge. In the other the Asn carboxamide group forms a C8/C7 H-bonded bridge with the carboxamide group facing in the opposite direction across an extended peptide backbone involving a CS interaction. Both Ac-Ala-Asn-NHBn and Ac-Asn-Asn-NHBn are found exclusively in a single conformation in which the peptide backbone engages in a type I beta-turn with its C10 H-bond. The Asn residue(s) stabilize this beta-turn via C6 H-bond(s) between the carboxamide C = O group and the same residue’s amide NH. These structures are closely analogous to the corresponding structures in Gin-containing peptides studied previously [Walsh, P. S. et al. PCCP 2016, 18, 11306-11322; Walsh, P. S. et al. Angew. Chem. Int. Ed. 2016, 55, 14618-14622], indicating that the Asn and Gln side chains can each configure so as to stabilize the same backbone conformations. Spectroscopic and computational evidence suggest that glutamine is more predisposed than asparagine to beta-turn formation via unusually strong side-chain-backbone hydrogen-bond formation. Further spectral and structural similarities and differences due to the side-chain length difference of these similar amino acids are presented and discussed.

Identification of novel benzothiopyranone compounds against Mycobacterium tuberculosis through scaffold morphing from benzothiazinones

In this study, three novel series of benzoxazinone, benzothiopyranone and benzopyranone derivatives were designed through scaffold morphing from benzothiazinones to target DprE1. All compounds were evaluated for their in vitro activities against Mycobacterium tuberculosis and cytotoxicity against Vero cell line. Among these three series, the benzothiopyranone series displayed excellent antimycobacterial activity and low cytotoxicity. In particular, compound 6b exhibited potent in vitro activity against both drug-susceptible and drug-resistant tuberculosis clinical strains with MICs <0.016 mu g/mL. In addition, compound 6b demonstrated excellent ADME/T and PK properties and potent in vivo efficacy with bactericidal activity in an acute mouse model of tuberculosis. The antituberculosis effect of compound 6b is most likely attributed to its excellent anti-DprE1 activity. As such, compound 6b is under evaluation as a potential clinical candidate for treatment of tuberculosis. The current study provided new insight into the structural and pharmacological requirements for DprE1 inhibitors as potent antitubercular agents. (C) 2018 Elsevier Masson SAS. All rights reserved.

Increase in furfural tolerance by combinatorial overexpression of NAD salvage pathway enzymes in engineered isobutanol-producing E. coli

To reduce the furfural toxicity for biochemical production in E. coli, a new strategy was successfully applied by supplying NAD(P) H through the nicotine amide salvage pathway. To alleviate the toxicity, nicotinamide salvage pathway genes were overexpressed in recombinant, isobutanol-producing E. coli. Gene expression of pncB and nadE respectively showed increased tolerance to furfural among these pathways. The combined expression of pncB and nadE was the most effective in increasing the tolerance of the cells to toxic aldehydes. By comparing noxE-and fdh-harbouring strains, the form of NADH, rather than NADH, was the major effector of furfural tolerance. Overall, this study is the application of the salvage pathway to isobutanol production in the presence of furfural, and this system seems to be applicable to alleviate furfural toxicity in the production of other biochemical.

DMSO-catalysed late-stage chlorination of (hetero)arenes

The chlorination of a bioactive compound can change its physiological properties and improve its pharmacokinetic and pharmacological profiles. It therefore has been an important strategy for drug discovery and development. However, the direct aromatic chlorination of complex bioactive molecules is too difficult to be practical. In fact, many functional groups such as hydroxyls, amines, amides or carboxylic acids may strongly restrain the reactivity of Cl+ by forming a halogen bond. Here we report a highly efficient aromatic chlorination of arenes that is catalysed by dimethyl sulfoxide with N-chlorosuccinimide as the chloro source. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, drugs and peptides. The multi-gram experiment and low-cost of N-chlorosuccinimide and dimethyl sulfoxide shows great potential for drug discovery and development in industrial applications. Late-stage aromatic chlorination of active pharmaceutical ingredients has enormous potential in drug discovery yet still features limited applicability due to issues of functional-group tolerance. Now, dimethyl sulfoxide is reported as catalyst for the chlorination of a diverse family of bioactive molecules in combination with N-chlorosuccinimide.

Redox responsive nanoparticle encapsulating black phosphorus quantum dots for cancer theranostics

Effective cancer treatment puts high demands for cancer theranostics. For cancer diagnostics, optical coherence tomography (OCT) technology (including photothermal optical coherence tomography (PT-OCT)) has been widely investigated since it induces changes in optical phase transitions in tissue through environmental changes (such as temperature change for PT-OCT). In this report, redox responsive nanoparticle encapsulating black phosphorus quantum dots was developed as a robust PT-OCT agent. Briefly, black phosphorus quantum dots (BPQDs) are incorporated into cysteine-based poly-(disulfide amide) (Cys-PDSA) to form stable and biodegradable nanoagent. The excellent photothermal feature allows BPQD/Cys-PDSA nanoparticles (NPs) as a novel contrast agent for high-resolution PT-OCT bioimaging. The Cys-PDSA can rapidly respond to glutathione and effectively release BPQDs and drugs in vitro and in vivo. And the obtained NPs exhibit excellent near-infrared (NIR) photothermal transduction efficiency and drug delivery capacity that can serve as novel therapeutic platform, with very low chemo drug dosage and side effects. Both of the polymer and BPQD are degradable, indicating this platform is a rare PT-OCT agent that is completely biodegradable. Overall, our research highlights a biodegradable and biocompatible black phosphorus-based nanoagent for both cancer diagnosis and therapy.
