Heteroarylation of alkenes with aryl iodides was efficiently achieved with a (MeDalphos)AuCl complex through Au-I/Au-III catalysis. The possibility to combine oxidative addition of aryl iodides and yr-activation of alkenes at gold is demonstrated for the first time. The reaction is robust and general (> 30 examples including internal alkenes, 5-, 6-, and 7-membered rings). It is regioselective and leads exclusively to trans addition products. The (P,N) gold complex is most efficient with electron-rich aryl substrates, which are troublesome with alternative photoredox/oxidative approaches. In addition, it provides a very unusual switch in regioselectivity from 5-exo to 6-endo cyclization between the Z and E isomers of internal alkenols.

Introduction: The root of Millettia speciosa Champ. (Leguminosae) is one of the well-known traditional Chinese medicines abundant in phenolic compounds and plays important roles in the treatment of pain or numbness of the joints, blood deficiency sallow, chronic bronchitis and chronic hepatitis. Objective: An ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) based chemical profiling approach was established for the separation and characterization of isoflavonoids in the roots of Millettia speciosa Champ. Methods: The roots of Millettia speciosa Champ. were prepared by ethanol extraction followed by further extraction with chloroform. The extracts were analyzed by UPLC-Q-TOF-MS in positive and negative electrospray ion modes at different Collision Energy (CE) values. Results: A total of 48 components were simultaneously detected, of which 38 components, including 21 isoflavones, 4 phenolic acids, 4 isoflavanones, 2 phenolic aldehydes, 2 flavanones, 1 aliphatic acid, 1 chalcone, 1 flavonol, 1 isoflavane and 1 pterocarpan were unambiguously identified or tentatively assigned based on the retention time, UV spectra, characteristic molecular ions, MS/MS fragmentation data and reference standards. The isomers of isoflavonoids were distinguished using accurate mass, the diagnostic fragmentations of C-ring and UV spectra. The major diagnostic fragment ions of isoflavonoids were observed and the corresponding fragmentation pathways were proposed. Conclusion: This investigation provides important analysis data for further quality control, pharmacological and toxicological research on Millettia speciosa Champ.

Astragalus mongholicus (MG) and Astragalus membranaceus (MJ), both generally known as Huangqi in China, are two perennial herbals widely used in variety diseases. However, there were still some differences in the chemical ingredients between MG and MJ. In this paper, metabolomics combined with the ultra-high performance liquid chromatography coupled with electrospray ionization/quadrupole time-of-flight mass spectrometry (UHPLC-ESI-Q-TOF-MS/MS) was employed to contrastively analyze the chemical constituents between MG and MJ. As a result, principal component analysis showed that MG and MJ were separated clearly. A total of 53 chemical markers were successfully identified for the discrimination of MG and MJ. Of them, the contents of 36 components including Astragaloside IIII, Astragaloside IV, Agroastragaloside I, etc. in MJ were significantly higher than those in MG. On the contrary, the contents of 17 other components including coumaric acid, formononetin, sophoricoside, etc. in MG were obviously higher than those in MJ. The results showed that the distinctive constituents in MG and MJ were remarkable, and MJ may own stronger pharmacological activities than MG. In a word, MG and MJ may be treated as two different herbs. This paper demonstrated that metabolomics was a vitally credible technology to rapidly screen the characteristic chemical composition of traditional Chinese medicine.

Terpenes constitute one of the largest groups of natural products. They exhibit a wide range of biological activities including antioxidant, anticancer, and drug resistance modulating properties. Saffron extract and its terpene constituents have been demonstrated to be cytotoxic against various types of cancer cells, including breast, liver, lung, pancreatic, and colorectal cancer. In the present work, we have studied anticancer properties of TMPE, a newly synthesized monoterpene derivative of beta-cyclocitral-the main volatile produced by the stigmas of unripe crocuses. TMPE presented selective cytotoxic activity to doxorubicin-resistant colon cancer cells and was identified to be an effective MDR modulator in doxorubicin-resistant cancer cells. Synergy between this derivative and doxorubicin was observed. Most probably, TMPE inhibited transport activity of ABCB1 protein without affecting its expression level. Analysis of TMPE physicochemical parameters suggested it was not likely to be transported by ABCB1. Molecular modeling showed TMPE being more reactive molecule than the parental compound-beta-cyclocitral. Analysis of electrostatic potential maps of both compounds prompted us to hypothesize that reduced reactivity as well as susceptibility to electrophilic attack were related to the lower general toxicity of beta-cyclocitral. All of the above pointed to TMPE as an interesting candidate molecule for MDR reversal in cancer cells.

Application In Synthesis of 1,1,1-Triethoxyethane. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Biological Evaluation of Natural and Synthesized Homovanillic Acid Esters as Inhibitors of Intestinal Fatty Acid Uptake in Differentiated Caco-2 Cells published in 2019.0, Reprint Addresses Lieder, B (corresponding author), Symrise AG, Muehlenfeldstr 1, D-53479 Holzminden, Germany.; Lieder, B (corresponding author), Univ Vienna, Dept Physiol Chem, CDL Taste Res, Althanstr 14, A-1090 Vienna, Austria..

With raising prevalence of obesity, the regulation of human body fat is increasingly relevant. The modulation of fatty acid uptake by enterocytes represents a promising target for body weight maintenance. Recent results demonstrated that the trigeminal active compounds capsaicin, nonivamide, and trans-pellitorine dose-dependently reduce fatty acid uptake in differentiated Caco-2 cells as a model for the intestinal barrier. However, non-pungent alternatives have not been investigated and structural determinants for the modulation of intestinal fatty acid uptake have not been identified so far. Thus, based on the previous results, we synthesized 23 homovanillic acid esters in addition to the naturally occurring capsiate and screened them for their potential to reduce intestinal fatty acid uptake using the fluorescent fatty acid analog Bodipy-C12 in differentiated Caco-2 cells as an enterocyte model. Whereas pre-incubation with 100 mu M capsiate did not change fatty acid uptake by Caco-2 enterocytes, a maximum inhibition of -47% was reached using 100 mu M 1-methylpentyl-2-(4-hydroxy-3-methoxy-phenyl)acetate. Structural analysis of the 24 structural analogues tested in the present study revealed that a branched fatty acid side chain, independent of the chain length, is one of the most important structural motifs associated with inhibition of fatty acid uptake in Caco-2 enterocytes. The results of the present study may serve as an important basis for designing potent dietary inhibitors of fatty acid uptake.

A method is developed for in situ generation of 1,3-dioxan-5-one derivatives 2. These compounds are simple precursors for accessing carbohydrate structures and previously had to be produced via stepwise procedures using excessive amounts of reagents. In the present work, three different derivatives of 2 were synthesized via the reaction of trialkoxyalkanes with dihydroxyacetone dimer 1 in the presence of acetic acid as the catalyst. In the same pot, derivatives of 2 were reacted with aromatic aldehydes and 30 mol% of pyrrolidine to obtain high yields of the respective bischalcones 3 within short time periods.

This manuscript details the impact of stabilizing agents on the structural, optical properties of Ag@SnO2 core shell nanoparticles and its biological applications. Three different stabilizing agent viz. Poly Vinyl Pyrrolidone (PVP), zeroth generation triazolyl glycodendrimer and zeroth generation triazolyl chalcone dendrimer were used as stabilizers in the synthesis of Ag@SnO2 nanoparticles. The results were compared to study their effect on the structural and optical properties of the synthesized samples. The structural parameters of the samples were investigated by XRD analysis, FESEM and HRTEM images. The presence of SnO2 shell on the Ag core was also corroborated by XPS results. The XRD data was used for refining and characterizing the elements present in the sample by Reitveld method. The average crystallite size, dislocation density, lattice parameters (a, c), lattice strain of the samples were calculated using XRD measurements. Williamson – Hall (W-H) method and Size Strain Plot (SSP) method were used to calculate the lattice strain of the synthesized sample. The concentric rings of the SAED pattern and the lattice fringe images exhibited the interplanar d-spacing values and the results were compared with XRD measurements. The optical properties of the samples were investigated using UV-Vis spectra and the band gap energy were calculated using Tauc plot. The Photoluminescence (PL) studies of the Ag@SnO2 core – shell nanoparticles with the three stabilizing agents are also discussed in this work. The antibacterial and antifungal activities of the chalcone dendrimer stabilized Ag@SnO2 core – shell nanoparticles were tested against the pathogens Bacillus subtilis, Proteus mirabilis, Candida albicans and Aspergillus niger.

UV-activated alkyne-alkene [2+2] cycloaddition has served as an important tool to access cyclobutenes. Although broadly adopted, the limitations with UV light as an energy source prompted us to explore an alternative method. Here we report alkyne-alkene [2+2] cycloaddition based on visible light photocatalysis allowing the synthesis of diverse cyclobutenes and 1,3-dienes via inter- and intramolecular reactions. Extensive mechanistic studies suggest that the localized spin densities at sp(2) carbons of alkenes account for the productive sensitization of alkenes despite their similar triplet levels of alkenes and alkynes. Moreover, the efficient formation of 1,3-dienes via tandem triplet activation of the resulting cyclobutenes is observed when intramolecular enyne cycloaddition is performed, which may serve as a complementary means to the Ru(II)-catalyzed enyne metathesis. In addition, the utility of the [2+2] cycloaddition has been demonstrated by several synthetic transformations including synthesis of various extended pi-systems.

Efficient hydrogenation of electron-deficient internal olefins and alkynes access to saturate ketone with CH3OH as a single hydrogen donor under electrochemical conditions has been successfully developed. This hydrogenation strategy can be used to convert electron-deficient internal olefins and alkynes to saturate ketone under electrochemical conditions with exogenous-reductant and a metal catalyst. Mechanistic studies reveal that radical hydrogenation was involved in this transformation. Notably, various electron-deficient internal olefins and alkynes could be tolerated in such an electrochemical hydrogenation synthetic strategy and can be easily scaled up with good efficiency.
