We report a mild palladium-catalyzed method for the selective allylation of 4-alkylpyridines in which highly basic pyridylic anions behave as soft nucleophiles. This method exploits alkylidene dihydropyridines, which are semi-stable intermediates readily formed using a ‘soft-enolization’ approach, in a new mechanistic manifold for decarboxylative allylation. Notably, the catalytic generation of pyridylic anions results in a substantially broader functional group tolerance compared to other pyridine allylation methods. Experimental and theoretical mechanistic studies strongly suggest that pyridylic anions are indeed the active nucleophiles in these reactions, and that they participate in an outer-sphere reductive elimination step. This finding establishes a new pK(a) boundary of 35 for soft nucleophiles in transition metal-catalyzed allylations.

Three novel ruthenium nitrosyl complexes [Ru(NO)Cl-3(InicMe)(2)] (1b), [RuNOCl3(NicEt)(2)] (1c) and [RuNOCl3(NicMe)(2)] (1d) (InicMe = methyl isonicotinate, NicEt = ethyl nicotinate, NicMe = methyl nicotinate)were prepared and crystal structure of the complexes were determined by single crystal XRD analysis. In all complexes, the organic ligands are coordinated by a pyridine nitrogen atom and located in trans-position each to other and in cis-position to NO group. In the crystal package of all compounds stacking interactions of two types were determined: pi(arene)-pi(arene) and pi(COO)-pi(arene) stacking. Finally, cytotoxicity of the compounds was tested on Hep2 and HepG2 cell lines. In the set of similar compounds mer-[RuNO(L)(2)Cl-3] (L = Py, gamma-Pic, beta-Pic, Inic-Alk, Nic-Alk), complexes with iso-nicotinic acid esters are the most toxic, while nicotinic acid derivatives are less toxic and compared with pyridine complex.

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. Category: pyridine-derivatives.

An unprecedented example of a NHC-catalyzed acylation reaction promoted by an oxidant CCl3CN is described. This protocol features several advantages, including mild reaction conditions, broad substrate scope, and easy operation. In addition, low cost, low boiling point, and small molecular weight allow CCl3CN to be an attractive and amenable oxidant. Meanwhile, this formal dehydrogenative coupling reaction of aldehydes and alcohols involves a hydride transfer process.

Purpose: We investigated Nw-hydroxy L-Arginine (NOHA) predictive response in serous ovarian carcinoma based on estrogen-hormone receptor expression status; and assessed the distinctive NOHA response between estrogen-receptor-negative (ER-) tumor subtypes of ovarian and breast cancer. Materials/methods: Three-dimensional (3D) spheroids models of ER- and estrogen-receptor-positive (ER+) from breast and ovarian tumor, cultured for 9 weeks, were assayed for cellular levels of inducible nitric oxide synthase (NOS2), nitric oxide (as total nitrite) and L-Arginine, and compared to NOHA in culture medium. Statistical difference was set at p < 0.01. Results: Nine-week in vitro studies showed a progressive NOHA reduction in culture medium by at least 0.4-0.8 fold, and 0.65-0.92 fold only in the ER-breast tumor and ER-ovarian tumor 3D spheroids, respectively; with increases in cellular NOS2 and nitric-oxide levels, by at least 1.0-2.45 fold in both ER-tumor subtype 3D spheroids (p < 0.01; n = 6). Within ER-subtypes, medium NOHA decreased by >= 38.9% in ovarian cancer over breast cancer 3D-spheroids, with cellular increases in NOS2 (by >= 17.4%), and nitric oxide (by >= 18.8%). Cellular L-Arginine to medium NOHA ratio was higher, and by at least 6.5-22.5 fold in ER-breast tumor 3D-spheroids, and at least 10-70 fold in ER-ovarian tumor 3D spheroids, than in ER+ and control conditions; and was >= 48% higher in ER-ovarian cancer than in ER-breast cancer 3D-spheroids. Conclusions: The present study shows NOHA as a sensitive and selective indicator differentiating and distinguishing ER-subtypes based on the tumor grade.

Schiff bases (SB) obtained from S-methyl dithiocarbazate and aromatic aldehydes: salicylaldehyde (H2L1), ovanillin (H2L2), pyridoxal (H2L3) and 2,6-diformyl-4-methylphenol (H3L4), and their corresponding Zn(II)complexes (1-4), are synthesized. All compounds are characterized by elemental analyses, infrared, UV-Vis, nuclear magnetic resonance spectroscopy and mass spectrometry. The structures of H2L2 and [Zn-2(L-1)(2)(H2O) (DMF)] (1a) (DMF = dimethylformamide) are solved by single crystal X-ray diffraction. The SB coordinates the metal center through the Ophenolate, Nimine and Sthiolate atoms. The radical scavenging activity is tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, with all ligand precursors showing IC50 values similar to 40 mu M. Cytotoxicity studies with several tumor cell lines (PC-3, MCF-7 and Caco-2) as well as a non-tumoral cell line (NHDF) are reported. Interestingly, 1 has relevant and selective antiproliferative effect against Caco-2 cells (IC50 = 9.1 mu M). Their antimicrobial activity is evaluated in five bacterial strains (Klebsiella pneumoniae, Acinetobacter baumannii, Listeria monocytogenes, Pseudomonas aeruginosa and Staphylococcus aureus) and two yeast strains (Candida albicans and Candida tropicalis) with some compounds showing bacteriostatic and fungicidal activity. The minimal inhibitory concentration (MIC90) of HnL against Mycobacterium tuberculosis is also reported, with H2L2 and H3L4 showing very high activity (MIC90 < 0.6 mu g/mL). The ability of the compounds to bind bovine serum albumin (BSA) and DNA is evaluated for H3L4 and [Zn-2(L-4)(CH3COO)] (4), both showing high binding constants to BSA (ca. 106 M 1) and ability to bind DNA. Overall, the reported compounds show relevant antitumor and antimicrobial properties, our data indicating they may be promising compounds in several fields of medicinal chemistry.

4-Hydroxymethyl-2-hetaryl(hetaroyl)furo[2,3-c]pyridines, the products of furan cyclization of pyridoxal with acylmethyl- and heteroarylmethyl halides, easily react with thionyl chloride in DMF to form new series of 4-chloromethyl-2-heteroaryl[2,3-c]pyridines. Further action of primary or secondary amines on these chloromethyl derivatives leads to the nucleophilic substitution of chlorine atoms with the formation of 4-aminomethyl-2-heteroaryl[2,3-c]pyridines. The study of anti-infective activity of the 4-RCH2-furo[2,3-c]pyridines (R = OH, Cl, (NRR2)-R-1) showed significant protistocidal and moderate antibacterial activity of some of representatives of these compounds.

behavior of cucurbituril-bipyridinium pseudorotaxane ligand by utilizing meta-functionalized bipyridinium dicarboxylate guest. A tailored pseudorotaxane precursor involving 1,1′-(hexane-1,6-diyl)bis(3-cyanopyridin-1-ium) bromide (C6BPCN3) and cucurbit[6]uril (CB[6]) has designed and synthesized. Through in situ hydrolysis of the pseudorotaxane ligands and their coordination assembly with uranyl cations, seven new uranyl-rotaxane coordination polymers URCP1-URCP7 have been obtained under hydrothermal conditions in the presence of different anions. It is demonstrated that the variation of carboxylate groups from para- to meta-position greatly affected the coordination behaviors of the metafunctionalized pseudorotaxane linkers, which are enriched from simple guest-only binding to host-guest simultaneous coordination and synergistic chelating. This effective regulation on uranyl coordination of supramolecular pseudorotaxane can be attributed to the proximity effect, which refers to the meta-position carboxyl group being spatially closer to the portal carbonyl group of CB[6]. Moreover, by combining other regulation methods such as introducing competing counterions and modulating solution acidity, the nuclearity of the uranyl center and the coordination patterns of the pseudorotaxane ligand can be diversely tuned, which subsequently exert great influence on the final dimensionality of resultant uranyl compounds. This work presents a large diversity of uranyl-based coordination polyrotaxane compounds with fascinating mechanically interlocked components and, most importantly, provides a feasible approach to adjust and control the metal coordination behavior of the pseudorotaxane ligand that might expand the scope of application of such supramolecular ligands.
