Hydrothermal reactions of Mn(II) or Cu(II) with the mixed ligands 2,2?-biquinoline-4,4?-dicarboxylic acid (H2bqdc), 4,4?-bispyridine (bipy) or dipyridin-2-ylamine (N3) lead to the isolation of two coordination polymers, namely, [Mn(bqdc)(bipy)]n (1) and {[Cu(bqdc)0.5(N3)2]·0.5bqdc·2H2O}n (2). Single-crystal X-ray analyses reveal that the complex 1 is the first three-dimensional non-interpenetrating 10-connected (312.430.52.6) topological framework with H2bqdc ligand, while the supramolecular structure of 2 exhibits a three-dimensional architecture via the pi-pi stacking interactions between the aromatic rings of N3 ligands and inter-chain hydrogen bonding. The H2bqdc ligand adopts bidentated and monodentated fashion in the 1 and 2, respectively. Moreover, compound 1 shows weak antimagnetic behavior.

An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.

In an attempt to refine a CAN-mediated synthesis of 1,3,4,6-tetra-O-acetyl-alpha-d-glucopyranose (2-OH glucose) we unexpectedly discovered that this reaction proceeds via the intermediacy of glycosyl nitrates. Improved mechanistic understanding of this reaction led to the development of a more versatile synthesis of 2-OH glucose from a variety of precursors. Also demonstrated is the conversion of 2-OH glucose into a variety of building blocks differentially protected at C-2, a position that is generally hard to protect regioselectively in the glucopyranose series.

This study demonstrated the combined use of sonolysis with the H2O2/ascorbic acid (Vc) redox reaction to degrade chitosan (CS). The influence of operating parameters, such as the initial CS concentration (1-15 mg mL-1), the input power level (15-45% of the total input power), the H2O2 and Vc concentration (10-70 mM) and the pH (3.0-5.0) of the reaction solution, on the molecular weight and degradation kinetics of CS were investigated and optimized. Based on the degradation kinetics, a synergetic effect of sonolysis with H2O2 and Vc on the degradation of CS was observed. Structural analysis by FT-IR and 1H and 13C NMR indicated no significant difference between the chemical structure of chitosan before and after degradation. Moreover, intermolecular hydrogen bonds were broken, and the crystallinity of degraded chitosan decreased. Using the above analysis, CS degradation by the combination of sonolysis with the H2O2/Vc redox reaction was proposed to be due to mechanical effects along with HO attack on the beta-1,4-glucoside linkages of glucosamine units. These results suggest that the sonolysis/H2O2/Vc combined technique is promisingly suitable for large-scale manufacture of chitooligosaccharide.

Two new mixed-ligand complexes [Fe(HG)2(dipyam)] (1) (HG = glycolato and dipyam = 2,2?-dipyridylamine) and [Cu(HB) 2(im)2]·2H2O (2) (HB = benzilato and im = imidazole) have been hydrothermally synthesized and structurally characterised by X-ray diffraction. In both cases the metallic centre is in an octahedral environment, strongly distorted in 2 (4+2 coordination). The alpha-hydroxycarboxylato ligands (glycolato or benzilato) present different coordinative behaviour, bidentade chelate through the hydroxyl oxygen and one carboxy oxygen in 1 and through the two oxygen atoms of the carboxylate group in 2. The complexes are extended into 2D frameworks through hydrogen bonding and pi…pi or C-H…pi interactions. The complexes were also characterized by elemental analysis, FT-IR and UV-vis spectroscopy and room temperature magnetic measurements.

Reaction between copper(II)- and zinc(II)-nitrates and 2,2?-dipyridyl(N-propenyl)amine (Prdpa) affords 1:1 complexes M(Prdpa)(NO3)2 (M = Cu, 1; M = Zn, 5) for both metal ions and a 1:2 adduct M(Prdpa)2(NO3)2 (2) for copper only. In ethanol 1 dissociates to form 2 and copper nitrate. X-ray diffraction studies on 1, 2 and 5, and on the 2,2?-dipyridylamine (Hdpa) analogue of 1, Cu(Hdpa)(NO3)2 (4), are reported. The metal centres exhibit square pyramidal (1) or distorted octahedral (2, 4, 5) primary coordination spheres. Bridging nitrate groups linking Cu atoms in 1 and 4 result in -Cu-O-N-O-Cu- chains, which in the case of 4 are extensively cross-linked by N – H···ONO2 H-bonding into 3D-arrays. Intermolecular C – H···ONO2 interactions are apparent in the solid-state structure of 2. The structural effects of replacing the N – H atom on Hdpa by a propenyl group in 6-coordinate Cu(II) complexes are assessed. Crown Copyright

NAMPT inhibitors may show potential as therapeutics for oncology. Throughout our NAMPT inhibitor program, we found that exposed pyridines or related heterocyclic systems in the left-hand portion of the inhibitors are necessary pharmacophores for potent cellular NAMPT inhibition. However, when combined with a benzyl group in the center of the inhibitors, such pyridine-like moieties also led to consistent and potent inhibition of CYP2C9. In an attempt to reduce CYP2C9 inhibition, a parallel synthesis approach was used to identify central benzyl group replacements with increased Fsp3. A spirocyclic central motif was thus discovered that was combined with left-hand pyridines (or pyridine-like systems) to provide cellularly potent NAMPT inhibitors with minimal CYP2C9 inhibition. Further optimization of potency and ADME properties led to the discovery of compound 68, a highly potent NAMPT inhibitor with outstanding efficacy in a mouse tumor xenograft model and lacking measurable CYP2C9 inhibition at the concentrations tested.

Lysobactin, also known as katanosin B, is a potent antibiotic with in vivo efficacy against Staphylococcus aureus and Streptococcus pneumoniae. It was previously shown to inhibit peptidoglycan (PG) biosynthesis, but its molecular mechanism of action has not been established. Using enzyme inhibition assays, we show that lysobactin forms 1:1 complexes with Lipid I, Lipid II, and Lipid IIAWTA, substrates in the PG and wall teichoic acid (WTA) biosynthetic pathways. Therefore, lysobactin, like ramoplanin and teixobactin, recognizes the reducing end of lipid-linked cell wall precursors. We show that despite its ability to bind precursors from different pathways, lysobactin’s cellular mechanism of killing is due exclusively to Lipid II binding, which causes septal defects and catastrophic cell envelope damage.
