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.

Introduction: colorectal cancer (CRC) continues to be difficult to diagnose due to the lack of reliable and predictive biomarkers. Objective: to identify blood-based biomarkers that can be used to distinguish CRC cases from controls. Methods: a workflow for untargeted followed by targeted metabolic profiling was conducted on the plasma samples of 26 CRC cases and ten healthy volunteers (controls) using liquid chromatography-mass spectrometry (LCMS). The data acquired in the untargeted scan was processed and analyzed using MarkerViewt software. The significantly different ions that distinguish CRC cases from the controls were identified using a mass-based human metabolome search. The result was further used to inform the targeted scan workflow. Results: the untargeted scan yielded putative biomarkers some of which were related to the folate-dependent one-carbon metabolism (FOCM). Analysis of the targeted scan found the plasma levels of nine FOCM metabolites to be significantly different between cases and controls. The classification models of the cases and controls, in both the targeted and untargeted approaches, each yielded a 97.2% success rate after cross-validation. Conclusion: we have identified plasma metabolites with screening potential to discriminate between CRC cases and controls.

L-threonine aldolase (LTA) is a PLP-dependent enzyme that can reversibly catalyze aldol reaction of glycine and acetaldehyde to produce beta-hydroxy-alpha-amino acids. In the present work, a putative Ita gene from Actinocorallia herbida (AhLTA) was mined and over-expressed in Escherichia coli BL21 (DE3). The substrate spectrum assay indicated that AhLTA only used glycine as donor substrate and tolerated a wild range of aromatic aldehydes as acceptor substrates. It was found that the type and position of substituents in the aromatic aldehydes exerted a significant impact on the activity and stereoselectivity at beta-carbon of AhLTA. Among those substrates, AhLTA could catalyze glycine and 4-methylsulphonyl benzaldehyde (14a) to produce L-threo-4-methylsulfonylphenylserine ((2S,3R)-14b) with high conversion (94.4%) and moderate stereoselectivity (19% de). By conditional optimization, the de value of (2S, 3R)-14b was improved to 61% and the conversion was 75%. Taken together, our study suggested that AhLTA might be a promising catalyst for producing chiral beta-hydroxy-alpha-amino acids. (C) 2020 Elsevier Ltd. All rights reserved.

A new and facile three-component method was developed for the synthesis of polymethylene-3-cyanopyridine-2(1H)-thiones by the domino Knoevenagel -> Michael -> heterocyclization -> dehydrogenation reaction from cycloalkanones, cyanothioacetamide, and polymethoxy-substituted benzaldehydes. The final dehydrogenation step was found to involve arylidenecyanothioacetamide. The resulting pyridinethiones and 4-chloroacetoacetic ester were introduced into the domino S(N)2 -> Thorpe-Ziegler -> Guareschi-Thorpe reaction to synthesize tetracyclic dipyridothiophenes. Starting from these compounds, 8,9-polymethylenepyranothienodipyridines were also synthesized by the domino Knoevenagel -> Michael -> hetero-Thorpe-Ziegler reaction. Furthermore, a method for the synthesis of thienodipyridine annulated to the steroid skeleton is proposed.

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.

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.

Iridium-catalyzed enantioselective transfer hydrogenation of ketones with formic acid was developed using a prolinol-phosphine chiral ligand. Cooperative action of the iridium atom and the ligand through alcohol-alkoxide interconversion is crucial to facilitate the transfer hydrogenation. Various ketones including alkyl aryl ketones, ketoesters, and an aryl heteroaryl ketone were competent substrates. An attractive feature of this catalysis is efficient discrimination between the alkyl and aryl substituents of the ketones, promoting hydrogenation with the identical sense of enantioselection regardless of steric demand of the alkyl substituent and thus resulting in a rare case of highly enantioselective transfer hydrogenation of tert-alkyl aryl ketones. Quantum chemical calculations revealed that the sp(3)-C-H/pi interaction between an sp(3)-C-H bond of the prolinol-phosphine ligand and the aryl substituent of the ketone is crucial for the enantioselection in combination with O-H center dot center dot center dot O/sp(3)-C-H center dot center dot center dot O two-point hydrogen-bonding between the chiral ligand and carbonyl group.
