Background/Aims: Hydrazone and acylhydrazone derivatives, which are produced from aldehyde reacting with hydrazine or acylhydrazine, have been reported to exhibit antitumor activities. However, the angionenic effects of this kind of derivatives haven’t been elucidated. Here, we synthesized 12 pyridoxal hydrazone and acylhydrazone compounds and investigated their antiangiogenic effects and the underlying mechanisms. Method: 3-(4,5-Dimethylthiazol-2-yl)-2, 5-dipheyltetrazolium bromide assay was used to screen the inhibitory effects of the synthesized compounds on endothelial cells (ECs) proliferation. The compound with best inhibitory effect was further evaluated with wound-healing assay and tube formation assay. Calcein-Am assay was carried out to determine the content of intracellular labile iron pool (LIP). Intracellular reduced glutathione (GSH) was determined by spectrophotometry. Flow cytometry was used to determine cell cycle and apoptosis. Results: Compound 10 (3-hydroxy-5-[hydroxymethyl]-2-methyl-pyridine-4-carbaldehyde-2-naphthalen-1-acetyl hydrazone) showed the best inhibitory effect on human umbilical vascular ECs proliferation, with IC50 value of 25.4 mu mol/L. It not only inhibited wound-healing and tube formation of ECs, but also decreased the content of intracellular LIP and GSH. Furthermore, it arrested ECs cycle at S phase and induced cell apoptosis. Conclusions: Compound 10 exhibits antiangiogenic effects by reducing the content of intracellular LIP and GSH, and subsequently arresting cell cycle and inducing cell apoptosis.

Background De novo lipogenesis (DNL) is the primary metabolic pathway synthesizing fatty acids from carbohydrates, protein, or alcohol. Our aim was to examine associations of in vivo levels of selected fatty acids (16:0, 16:1n7, 18:0, 18:1n9) in DNL with incidence of type 2 diabetes (T2D). Methods and findings Seventeen cohorts from 12 countries (7 from Europe, 7 from the United States, 1 from Australia, 1 from Taiwan; baseline years = 1970-1973 to 2006-2010) conducted harmonized individual-level analyses of associations of DNL-related fatty acids with incident T2D. In total, we evaluated 65,225 participants (mean ages = 52.3-75.5 years; % women = 20.4%62.3% in 12 cohorts recruiting both sexes) and 15,383 incident cases of T2D over the 9-year follow-up on average. Cohort-specific association of each of 16:0, 16:1n7, 18:0, and 18:1n9 with incident T2D was estimated, adjusted for demographic factors, socioeconomic characteristics, alcohol, smoking, physical activity, dyslipidemia, hypertension, menopausal status, and adiposity. Cohort-specific associations were meta-analyzed with an inverse-varianceweighted approach. Each of the 4 fatty acids positively related to incident T2D. Relative risks (RRs) per cohort-specific range between midpoints of the top and bottom quintiles of fatty acid concentrations were 1.53 (1.41-1.66; p< 0.001) for 16:0, 1.40 (1.33-1.48; p< 0.001) for 16:1n-7, 1.14 (1.05-1.22; p = 0.001) for 18:0, and 1.16 (1.07-1.25; p< 0.001) for 18:1n9. Heterogeneity was seen across cohorts (I-2 = 51.1%-73.1% for each fatty acid) but not explained by lipid fractions and global geographical regions. Further adjusted for triglycerides (and 16:0 when appropriate) to evaluate associations independent of overall DNL, the associations remained significant for 16:0, 16:1n7, and 18:0 but were attenuated for 18:1n9 (RR = 1.03, 95% confidence interval (CI) = 0.94-1.13). These findings had limitations in potential reverse causation and residual confounding by imprecisely measured or unmeasured factors. Conclusions Concentrations of fatty acids in the DNL were positively associated with T2D incidence. Our findings support further work to investigate a possible role of DNL and individual fatty acids in the development of T2D. Formula: C8H10ClNO3.

The Name is Phenyl(pyridin-2-yl)methanone. Through research, I have a further understanding and discovery of 91-02-1.

A series of bidendate pyridine-functionalized metal N-heterocyclic carbene (NHC) complexes with various wingtip substituents (R = methyl, phenyl and tert-butyl) had been prepared from silver oxide-mediated transmetalation method. The basic backbone of the NHC ligands were prepared in two step-wise reactions: reduction of the commercially available 2-benzoylpyridine, followed by halogenation to yield 2-(chloro(phenyl) methyl) pyridine. Subsequent reactions with different imidazoles gave the desired imidazolium salts (or NHC precursors) with different R groups at the N wingtip (R = Me, Ph, t-Bu). Transmetalation of the imidazolium salts into platinum NHC complexes were achieved by using Ag2O mediated method with Pt(cod)Cl-2 as the transmetalating agent. On the other hand, nickel NHC complexes were obtained via one pot synthesis method with nickel chloride as the transmetalating agent and reflux in the presence of a base. Following recrystallisation, the molecular structure of Pt NHC complex (+/-)-5a had been successfully elucidated via single crystal X ray diffraction (XRD) analysis. The six-membered ring of the platinum NHC complexes adopted a boat conformation with the phenyl ring arranged at the axial position. Meanwhile, two unexpected nickel complexes, i.e. a simple nickel coordination complex and a nickelate complex, were obtained and studied using XRD. These Pt NHC complexes and unexpected Ni complexes were evaluated for their in vitro antimicrobial and anticancer activities against a panel of pathogenic microorganisms and three selected human cancer cell lines, including breast (MCF7), colon (HCT116) and oral (H103) cancer cells. Generally, the Pt NHC complexes displayed enhanced antimicrobial activities upon coordination to metals, as compared to the corresponding imidazolium salts i.e. NHC precursors, with minimum inhibitory concentration (MIC) values in micromolar (mM) range. A couple of platinum NHC complexes synthesized exhibited antimicrobial activities with MIC as low as 2 mM, which are comparable to silver NHC complexes with renowned antimicrobial profiles. Similarly, upon coordination to the metals, the cytotoxic effects of the platinum NHC complexes increased significantly as compared to the imidazolium salts. Among all, platinum NHC complex (+/-)-5c displayed significant cytotoxicities towards the cancer cells with IC50 values that are two to three times lower than that of the anticancer drug cisplatin. In summary, evidences for influence of both wingtip substituents and metals on the biological activities of the complexes have been found. (C) 2019 Elsevier B.V. All rights reserved.

Direct alkylation and arylation of allylic C(sp3)-H bonds are straight-forward approaches for accessing allylic C-C products. However, the engagement of allylic C-C bond- forming reaction without introducing extraneous functional groups and stoichiometric oxidant or reductant has proved difficult. Here, we report a general and mild strategy using semiconductor quantum dots (QDs) as photocatalysts for coupling a broad range of available allylic C(sp(3))-H bonds with alpha- amino C-H bonds or heteroarenes, respectively, under sunlight irradiation (> 85 examples). The protocol bypasses stoichiometric oxidant or reductant and pre-functionalization of both the coupling partners and produces hydrogen (H-2) as the byproduct. The outstanding efficiency and selectivity and step- and atom-economy represents the first direct alkylation and arylation of allylic C(sp(3))-H bonds with hydrogen evolution powered by solar energy.

Two diastereoisomers of bis(2-benzoylpyridine-O,N)dichloridonickel(II) have been isolated from the reactions of nickel(II) chloride hexahydrate and the organic ligand depending on the reaction solvent (ethanol, acetonitrile) used. DFT studies indicate that one of the isomers is more stable in both solvents, but nevertheless different diastereoisomers are crystallized from the two solvents. The two complexes represent the first pair of well characterized diastereoisomers in the coordination chemistry of 2-pyridyl ketones, providing a new example in the chemistry of octahedral MA(2)(BC) over cap (2) complexes (A = a monodentate ligand, (BC) over cap = an unsymmetrical bidentate chelate).

A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.

The photoswitching properties of three readily accesible benzoylpyridine hydrazones were investigated. Interestingly, replacing classical stirring with ultrasound wave activation results in pure thermodynamically less stable E isomer crystallization at room temperature. The studied benzoylpyridine hydrazones exhibit both P- and T-photochromic behaviour, depending on the benzoyl substituent, and improved addressability compared to most of the previously published pyridyl based hydrazones and 2-pyridylcarboxaldehyde acylhydrazones. Low activation entropy and calculated transition state geometry favour the inversion mechanism of their thermal isomerization rather than tautomerization followed by rotation recently found for pyridyl-hydrazone ester or nitrile rotary switches. The association behaviour of the nitro derivative during its thermal E-to-Z isomerization in highly polar DMSO indicates an important role of intermolecular hydrogen bonding in the thermal kinetics of benzoylpyridine-based hydrazone photoswitches. Moreover, the addition of triethylamine significantly accelerates the rate of Z-isomer thermal isomerization from days to seconds and could thus pave the way to fast pyridyl hydrazone T-type photochromic compounds in polar solvents. This study could therefore contribute to general knowledge related to the photochromic behaviour of hydrazones as an important class of modern photoswitches.

A pyrimidine moiety exhibiting a wide range of pharmacological activities has been employed in the design of privileged structures in medicinal chemistry. To prepare libraries of novel heterocyclic compounds with potential biological activities, a series of novel 2-(pyridin-2-yl) pyrimidine derivatives were designed, synthesized and their biological activities were evaluated against immortalized rat hepatic stellate cells (HSC-T6). Fourteen compounds were found to present better anti-fibrotic activities than Pirfenidone and Bipy55 ‘ DC. Among them, compounds ethyl 6-(5-(p-tolylcarbamoyl)pyrimidin-2-yl)nicotinate (12m) and ethyl 6-(5-((3,4-difluorophenyl)carbamoyl)pyrimidin-2-yl)nicotinate (12q) show the best activities with IC50 values of 45.69 mu M and 45.81 mu M, respectively. Furthermore, the study of anti-fibrosis activity was evaluated by Picro-Sirius red staining, hydroxyproline assay and ELISA detection of Collagen type I alpha 1 (COL1A1) protein expression. Our study showed that compounds 12m and 12q effectively inhibited the expression of collagen, and the content of hydroxyproline in cell culture medium in vitro, indicating that compounds 12m and 12q might be developed the novel anti-fibrotic drugs.
