A chemical sensor composed of pyridoxal hydrochloride schiff base based on diarylethene (1O) was synthesized. Its photochemical properties and selectivity to ions were further studied. The chemosensor could detect cyanide effectively and is almost undisturbed by other ions. When titrating CN-, the reaction aroused a distinct change in the absorption spectrum with the color change from transparent to yellow, and the fluorescence intensity centered at 562 nm was increased 68 folds. It also exhibited a good fluorescence sensing of Mg(2+ )with high selectivity and sensitivity. Upon addition of Mg2+, its emission intensity enhanced 110 folds, with the color change from dark to bright blue. Its good spectral response could be applied to molecular logic circuit. Moreover, the chemosensor could be made into test paper strips for the qualitative and quantitative detection of CN- and Mg2+.

Two new dimeric Zn(II) ([{ZnL1(DMSO2)}(2)]center dot DMSO (1), [{(ZnLCl)-Cl-2}(2)] (2)) and a novel tetrameric Zn(II) complex ([(Zn2L3)(2)(mu-OAc)(2)(mu(3)-O)(2)] (3)), where H2L1 = 4-(p-methoxyphenyl) thiosemicarbazone of o-hydroxynapthaldehyde, HL2 = 4-(p-methoxyphenyl)thiosemicarbazone of benzoyl pyridine and H2L3 = 4-(p-chlorophenyl)thiosemicarbazone of o-vanillin are reported. Ligands and their complexes were characterized by spectroscopic and single crystal X-ray diffraction techniques. In addition, the complexes exhibited good binding affinity towards HSA (10(12)M(-1)), which is supported by their ability to quench the tryptophan fluorescence emission spectra of HSA. The complexes were also screened for their DNA binding propensity through UV-vis absorption titration, circular dichroism and fluorescence spectral studies. Results show that they effectively interact with CT-DNA through an intercalative mode of binding, with binding constants ranging from 10(3) to 10(4) M-1. Among the three complexes 1 has the highest binding affinity towards CT-DNA. Further, the phosphatase activity was evaluated using bis(2,4-dinitrophenyl)phosphate (BDNPP) as substrate, however, the complexes did not yield any measurable catalytic activity. Nevertheless the complexes showed significant cytotoxic potential against HeLa and HT-29 cancer cell lines that was assessed through MTT assay and DAPI staining. Remarkably, complex 1 showed better activity than cisplatin against HT-29 cell line.

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.

Kinases and phosphatases are key enzymes in cell signal transduction pathways. Imbalances in these enzymes have been linked to numerous disease states ranging from cancer to diabetes to autoimmune disorders. The two isoforms (IFA and IFB) of Low Molecular Weight Protein Tyrosine Phosphatase (LMW-PTP) appear to play a role in these diseases. Pyridoxal 5′-phosphate (PLP) has been shown to act as a potent but, impractical micromolar inhibitor for both isoforms. In this study, a series of non-hydrolysable phosphonate analogs of PLP were designed, synthesized and tested against the two isoforms of LMW-PTP. Assay results demonstrated that the best inhibitor for both isoforms was compound 5 with a K-is of 1.84 mu M (IFA) and 15.6 mu M (IFB). The most selective inhibitor was compound 16, with a selectivity of roughly 370-fold for IFA over IFB.

Although pyridine derivatives are versatile supporting ligands in catalysis, the development of their chiral versions has been relatively limited. Herein, we report the design, synthesis, and proof-of-concept application of a structurally tunable chiral pyridine framework featuring an annulated compact ring system. Using an N,B-bidentate ligand skeleton containing the chiral pyridine moiety, we have developed an enantioselective iridium-catalyzed desymmetrizing C-H borylation reaction of diaryl(2-pyridyl)methane compounds with up to 96% ee and 93% yield. The resulting borylation products could be readily transformed into various chiral tri(hetero)arylmethane compounds. Density functional theory investigations revealed that the two chair conformations of the flexible ketal motif both favored the enantiomer that was consistent with experimental results. This work has thus introduced an effective and tunable chiral pyridine ligand framework that may be used in many catalytic asymmetric transformations.

Schisandra chinensis (Turcz.) Baill. is one of the important traditional medicinal plants in East Asia. It is a dioecious plant with aromatic flowers. The female and male flowers of S. chinensis possess slightly different fragrance characteristics. The overall scent of S. chinensis flowers is quite similar to that of Syringa dilatata (Korean lilac) flowers. Hence, this study aimed to understand the aromatic profile of the hexane extract from female and male flowers of S. chinensis and to compare their profile with the hexane extract of Korean lilac flowers. The chemical composition of hexane extract was determined by gas chromatography and mass spectrometry (GC-MS) analysis. In total, 67 different components were detected in the hexane extract of female (48) and male flowers (51) of S. chinensis; 32 of which were common to both female and male flowers. In regards to gender difference, 16 components were found only in female flowers, and 19 components were found only in male flowers. The results revealed that the most abundant components in the hexane extract of both female and male flowers were lilac alcohol C (9.53 and 7.00%), lilac alcohol A (6.55 and 5.71%), n-hexadecanoic acid (6.21 and 6.96%), linoleic acid (5.14 and 7.61%), beta-elemene (5.12 and 1.99), and lilac aldehyde D (4.13 and 4.97%). The data suggest that the major compounds in the hexane extract of S. chinensis flowers were generally similar, but they varied quantitatively according to gender. The presence of 10 components in both S. chinensis and Korean lilac flowers may be responsible for their similar fragrance characteristics. It could be concluded that the different fragrance characteristics of these flowers may be due to the presence of several gender-specific aromatic compounds in minor percentages.

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.

Category: pyridine-derivatives. I found the field of Chemistry very interesting. Saw the article A novel cluster of C-5-curcuminoids: design, synthesis, in vitro antiproliferative activity and DNA binding of bis(arylidene)-4-cyclanone derivatives based on 4-hydroxycyclohexanone scaffold published in 2019.0, Reprint Addresses Huber, I (corresponding author), Univ Pecs, Dept Pharmaceut Chem, H-7624 Pecs, Hungary.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde.

A new series (6) of C-5-curcuminoid derivatives (2E,6E-2,6-dibenzylidene-4-hydroxycyclohexanones) is described here with their evaluation for in vitro antiproliferative activities. Evaluation of 31 compounds against human A2780 (ovarian), C33A (cervix) and MDA-MB-231 (breast) cancer cell lines was performed to obtain structure activity relation data. The best performer was (2E,6E)-2,6-bis(3 ‘-nitrobenzylidene)-4-hydroxycyclohexanone (6h) with IC50 values of 0.68 mu M (A2780), 0.69 mu M (C33A) and 0.92 mu M (MDA-MB-231) compared to cisplatin with 1.30 mu M, 3.69 mu M and 19.13 mu M, respectively. According to calculated physicochemical properties some members in series 6, namely (2E,6E)-2,6-bis[(4 ‘-pyridinyl)methylene]-4-hydroxycyclohexanone (6p) [IC50 = 0.76 mu M (A2780), 2.69 mu M (C33A), 1.28 mu M (MDA-MB-231)] seem to have improved bioavailability compared to curcumin. Selected members of series 6 were involved in circular dichroism spectroscopic measurements in order to determine their interaction with natural DNA. Based on these data, we conclude that these derivatives do not bind to DNA in vitro. A proposal is summarized based on mass spectrometric assessment for fingerprint analysis in biological research of such C-5-curcuminoids.
