Barut, Burak published the artcileWater soluble axially morpholine disubstituted silicon phthalocyanines: Synthesis, characterisation, DNA/BSA binding, DNA photocleavage properties, Name: 3-Morpholinophenol, the publication is Synthetic Metals (2017), 22-32, database is CAplus.

In this study axially 1-morpholinopropan-2-ol disubstituted silicon phthalocyanine 4 and axially 3-morpholinophenol disubstituted silicon phthalocyanine 5 and their quaternised water soluble derivatives (4a and 5a) were synthesized for the first time. The structural characterisations of these novel compounds were performed by a combination of FT-IR, ¹H NMR, UV-vis and mass. The binding propensity of the compounds with CT-DNA was performed using UV-vis absorption titration, competitive ethidium bromide and thermal denaturation experiments These studies revealed that 4a and 5a intercalate to CT-DNA with 3.94 ± (0.11) × 10⁴ M^-1 and 1.71 ± (0.09) × 10⁴ M^-1. The DNA cleavage ability of 4a and 5a was investigated using supercoiled pBR322 plasmid DNA on agarose gel electrophoresis. 4a indicated excellent photocleavage activity under light irradiation at 650 nm in a concentration-dependent manner. However, 5a showed low cleavage activities under light irradiation at 12.5 μM and 25 μM but it had moderate cleavage activity at 50 μM. The BSA interaction experiment showed that quenching mechanisms of BSA with 4a and 5a were found as static quenching using UV-vis spectroscopy. All of these results suggest that 4a has a superior photosensitizer agent for photodynamic therapy to that of 5a due to DNA photocleavage properties.

Barut, Burak published the artcileNovel water soluble morpholine substituted Zn(II) phthalocyanine: Synthesis, characterization, DNA/BSA binding, DNA photocleavage and topoisomerase I inhibition, SDS of cas: 27292-49-5, the publication is International Journal of Biological Macromolecules (2017), 105(Part_1), 499-508, database is CAplus and MEDLINE.

In this study, novel peripherally tetra 3-morpholinophenol substituted zinc(II) phthalocyanine (4) and its water soluble form quaternized zinc(II) phthalocyanine (ZnQ) were synthesized for the first time. These novel compounds were characterized by a combination of different spectroscopic techniques such as FT-IR, ¹H NMR, ¹³C NMR, UV-vis and mass. The DNA binding of ZnQ was investigated using UV-vis absorption titration, competitive ethidium bromide, thermal denaturation and viscosity experiments that the ZnQ bound to CT-DNA via intercalation mode. ZnQ indicated photocleavage activity on supercoiled pBR322 plasmid DNA via formation of singlet oxygen under irradiation at 700 nm. Besides, the topoisomerase I inhibitory effect experiments showed that ZnQ inhibited topoisomerase I enzyme in a concentration-dependent manner. The bovine serum albumin (BSA) binding experiments indicated that ZnQ bound to proteins through a static quenching mechanism. All of these results claim that ZnQ has potential agent for photodynamic therapy owing to its nucleic acid interactions and photobiol. or photochem. properties.

Guo, Jing published the artcileExtended suspect screening strategy to identify characteristic toxicants in the discharge of a chemical industrial park based on toxicity to Daphnia magna, Recommanded Product: Triisopropanolamine, the publication is Science of the Total Environment (2019), 650(Part_1), 10-17, database is CAplus and MEDLINE.

With an increasing amount of industrial wastewater being discharged and the numerous chems. existed in, methods to identify toxicants in such complex matrixes are urgently needed for source control and quality management. In vivo toxicity to Daphnia magna was evaluated in the effluent of a wastewater treatment plant (WWTP). An extended suspect screening strategy was performed by bioassay-directed fractionation, accompanied with suspect screening of 228 suspect chems. in toxic fractions based on their mass characteristics and chromatog. characteristics. A toxicity evaluation of the original samples, organic components extracted by solid-phase extraction (SPE) and the filtered samples showed that organic compounds extracted by SPE were the main toxic components. Four of the 26 fractions of the organic extracts exhibited a toxic unit (TU) >1.0, with hydrophobic organic compounds contributing most to the toxicity. Twenty-eight of the 228 suspects were identified in four toxic fractions, with 53.6% of the suspects elucidated by spectrum interpretation based on mass characteristics and 53.8% more false pos. suspects removed based on chromatog. characteristics. Finally, 6 pollutants, including imazalil, prometryn, propiconazole, tebuconazole, buprofezin and diazinon, were further confirmed and explained 48.79% of the observed toxicity. With 2.48 times more of the toxicity explained and 90% of the labor saved, the extended suspect screening strategy enabled more efficient and reliable identification compared to traditional quant. anal. and non-target screening, especially for identification of characteristic toxicants in complex environmental matrixes.

Lacroix, Pauline M. published the artcileHPLC and NMR methods for the quantitation of the (R)-enantiomer in (-)-(S)-timolol maleate drug raw materials, Recommanded Product: 4-Morpholino-1,2,5-thiadiazol-3-ol, the publication is Chirality (1994), 6(6), 484-91, database is CAplus.

HPLC and ¹N-NMR methods for the quantitation of the (R)-enantiomer in (-)-(S)-timolol maleate were developed and validated. The HPLC method requires a 25 cm × 4.6 nm 5 μm Chiracel OD-H (cellulose tris-3,5-dimethylphenylcarbamate) column, a mobile phase of 0.2% (volume/volume) diethylamine and 4% (volume/volume) isopropanol in hexane at a flow rate of 1 mL/min and UV detection at 297 nm. A system suitability test was devised to verify the separation of the (R)- and (S)-enantiomers of timolol from other drug-related impurities. The NMR method requires the use of a high-field NMR spectrometer (> 360 MHz) and a chiral solvating agent, (-)-(R)-2,2,2-trifluoro-1-(9-anthrylethanol)(R-TFAE). The limits of quantitation were 0.5% and 0.2% (m/m) for HPLC and NMR, resp. The methods were applied to the determination of the (R)-enantiomer in eight lots of raw material. The results for the two methods were in very good agreement, with results ranging from 0.1 to 4.1% (m/m) by HPLC and none detected to 4.3% (m/m) by NMR. The USP method for sp. rotation was found to be unsuitable for detecting the presence of low levels of the (R)-enantiomer in (-)-(S)-timolol maleate.

Roque, Ana Carolina Abbud Hanna published the artcileConformational analysis for infrared spectroscopy and theoretical calculations of some 2-bromo-2-propyl 2-aryl-acetates, ibuprofen and naproxen analogs, SDS of cas: 55376-31-3, the publication is Journal of Molecular Structure (2021), 130027, database is CAplus.

Conformational anal. of new para-substituted 2-bromo-2-Pr 2-aryl-acetates (Y = H, OMe, Cl, and NO₂) (R1), ibuprofen (R2), and naproxen (R3) analogs using IR (IR) spectroscopy and theor. calculations was performed to determine the preferential conformers of these compounds in solvents with increasing polarity (CCl₄, CH₃Cl, and CH₃CN). The aryl-bromo-esters were synthesized via the esterification of 2-bromo-2-methylpropan-1-ol and the corresponding carboxylic acids, with good yields (∼36-70%). The IR spectra showed that these compounds presented only one conformation, and the exptl. data were supported by the theor. results obtained by d. functional theory (DFT) calculations using the 6311+G (2df, 2p) basis set. The calculations revealed that all the studied compounds presented two stable geometric conformations, which agrees with the data obtained exptl. in CCl₄. Theses conformers are stabilized by intramol. hydrogen bonds. However, the orbital interaction calculations using the natural bond orbital (NBO) method showed that the η_O→σ*_C-C,η_O→σ*_C-O, η_O→σ*_C-O and η_O→π*_C-O hyper-conjugations are the main interactions that stabilize the conformations. The compounds preferentially adopt the anti-conformation because the steric effect between the gauche bromo and oxygen atoms overrides the hyper-conjugative interactions, in addition to the stabilizing σ_C-H→ σ*_C-Br interactions in the conformers.

Taladrid, Diego published the artcileHypertension- and glycaemia-lowering effects of a grape-pomace-derived seasoning in high-cardiovascular risk and healthy subjects. Interplay with the gut microbiome, Synthetic Route of 621-37-4, the publication is Food & Function (2022), 13(4), 2068-2082, database is CAplus and MEDLINE.

Grape pomace (GP) is a winery byproduct rich in polyphenols and dietary fiber. Some recent results suggest that GP-derived extracts could be promising additives in food, specially recommended for low-salt diets. The hypothesis tested in this paper is that the regular consumption of GP-derived seasonings could help in the control of hypertension and glycemia. A randomized intervention study (6 wk) was performed in high-risk cardiovascular subjects (n = 17) and in healthy subjects (n = 12) that were randomly allocated into intervention (2 g day-1 of GP seasoning) or control (no seasoning consumed) groups. Blood samples, faeces, urine and blood pressure (BP) were taken at the baseline and at the end of the intervention. Faecal samples were analyzed for microbiota composition (16S rRNA gene sequencing) and microbial-derived metabolites (short chain fatty acids and phenolic metabolites). Among the clin. parameters studied, BP and fasting blood glucose significantly decreased (p < 0.05) after the seasoning intervention, but not for the control group. Notably, application of a novel approach based on ASV (Amplicon Sequence Variant) co-occurrence networks allowed us to identify some bacterial communities whose relative abundances were related with metadata. Our primary findings suggest that GP-seasoning may help in the modulation of cardiometabolic risk factors, mainly in the early stages. Furthermore, it evidences modulation of gut microbiota and functional bacterial communities by grape pomace, which might mediate the cardiometabolic effects of this byproduct.

Soon, Geok Hong published the artcileSynthesis, co-polymerization, and electrochemical evaluation of novel ferrocene-pyrrole derivatives, Computed Properties of 23351-09-9, the publication is Analytical Letters (2011), 44(11), 1976-1995, database is CAplus.

New ferrocene derivatives, (6-(4-(1H-pyrrol-1-yl)phenoxy)hexyl) ferrocene (1) and ((4-(1H-pyrrol-1-yl)phenoxy)carbonyl) ferrocene (2) were synthesized, characterized, and electrochem. evaluated as redox active films formed via anodic oxidation with pyrrole. Thin film studies were conducted and films formed from both compounds resulted in a stable Fe^II/III redox couple with E^o = 0.035 V and 0.365 V vs. Ag/Ag⁺ for (1) and (2), resp. Both potential sweeping and chronocoulometry were employed for film formation with the former resulting in controllable, reproducible film deposition. Growth conditions and solution concentrations were varied to assess influence on electrochem. behavior. Surface coverage was of the order 10^-8-10^-9 mol cm^-2, surface confined behavior (i_p vs. ν) was evident up to 0.2 V s^-1 with semi-infinite diffusion (i_p vs. ν^1/2) dominating at higher scan rates. Laviron theory was employed where possible for the determination of electron transfer coefficient and rate constants

Pothakos, Vasileios published the artcileFermentation Titer Optimization and Impact on Energy and Water Consumption during Downstream Processing, Product Details of C6H10O7, the publication is Chemical Engineering & Technology (2018), 41(12), 2358-2365, database is CAplus and MEDLINE.

A common focus of fermentation process optimization is the product titer. Different strategies to boost fermentation titer target whole-cell biocatalyst selection, process control, and medium composition Working at higher product concentrations reduces the water that needs to be removed in the case of aqueous systems and, therefore, lowers the cost of downstream separation and purification Different approaches to achieve higher titer in fermentation are examined Energy and water consumption data collected from different Cargill fermentation plants, i.e., ethanol, lactic acid, and 2-keto-L-gulonic acid, confirm that improvements in fermentation titer play a decisive role in downstream economics and environmental footprint.
