Biosynthesis of Stereoisomers of Dill Ether and Wine Lactone by Pleurotus sapidus

The white-rot fungus Pleurotus sapidus (PSA) biosynthesizes the bicyclic monoterpenoids 3,6-dimethyl-2,3,3a,4,5,7a-hexahydrobenzofuran (dill ether) (1) and 3,6-dimethy1-3a,4,5,7a-tetrahydro-1-benzofuran-2(3H)-one (wine lactone) (2). Submerged cultures grown in different media were analyzed by gas chromatography-mass spectrometry. The stereochemistry of the formed isomers was elucidated by comparing their retention indices to those of reference compounds by enantioselective multidimensional gas chromatography. The basidiomycete produced the rare (3R,3aR,7aS) and (3S,3aR,7aS) stereoisomers of dill ether and wine lactone. Kinetic analyses of the volatilome and bioprocess parameters revealed that the biosynthesis of the bicyclic monoterpenoids correlated with the availability of the primary carbon source glucose. Spiking the media with C-13 -labeled glucose demonstrated that the compounds were produced de novo. Supplementation studies i.a. with isotopically labeled substrates further identified limonene and p-menth-1-en-9-ol as intermediate compounds in the fungal pathways. PSA was able to biotransform all enantiomeric forms of the latter compounds to the respective isomers of dill ether and wine lactone.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 174775-48-5 help many people in the next few years. COA of Formula: C11H11NO3.

Pd-catalyzed C-H bond activation of Indoles for Suzuki reaction

We present a practical method for Suzuki coupling by which unprotected or N-protected indoles may be selectively arylated in the C2-position through direct C-H bond activation by electrophilic Pd(TFA)2 catalyst. The protocol is operationally simple as it is carried out in dioxane/water mixture, and air as the sole oxidant at room temperature. Various 2-arylated indoles were obtained in good yields. The protocol works for benzofuran, pyrrole and thiophene also. Graphic abstract Selective C-2 arylation of heterocycles using Pd(II) catalyst via C-H activation was performed under ambient condition.

Synthesis, characterization and spectroscopic investigation of N-(2-acetylbenzofuran-3-yl)acrylamide monomer: Molecular structure, HOMO-LUMO study, TD-DFT and MEP analysis

In this study, a novel acrylamide monomer was synthesized and characterized by UV-Vis, FT-IR and H-1 NMR measurements. The acrylamide monomer namely, N-(2-acetyl-benzofuran-3-yl)acrylamide (NABA), was prepared in two steps. In the first step, 1-(3-aminobenzofuran-2-yl)ethan-1 -one was synthesized by the reaction of 1-chloroacetone with 2-hydroxy-benzonitrile under basic conditions. In the second step, the obtained 1-(3-aminobenzofuran-2-yl)ethan-1 -one was reacted with acryloyl chloride and triethylamine at 0-5 degrees C temperature for obtaining NABA monomer. Then, the structural, vibrational, nuclear magnetic resonance and electronic properties for the synthesized monomer were determined by quantum chemical calculations of DFT method. The results were compared with experimental FT-IR, H-1 NMR and UV-Vis spectral data. The band gap of HOMO and LUMO show that the NABA monomer is chemically active and has charge transfer within the monomer. Moreover, molecular electrostatic potential (MEP) maps were drawn to identify reactive regions of NABA monomer. (C) 2019 Elsevier B.V. All rights reserved.

Synthesis and Evaluation of Some Novel Essential Amino Acid-Benzofuran-Acetamide/Propanamide/Butanamide Hybrids as Potential Anticonvulsant Agents

In this study, some new essential amino acid-benzofuran-acetamide/propanamide/butanamide hybrid derivatives were synthesized. The structures of the synthesized compounds were confirmed on the basis of their elemental and spectral analyses. Their anti-seizure activity was investigated using maximal electroshock seizure (MES) and subcutaneous metrazol (scMET) seizure tests in mice. Neurotoxicity (NT) of the synthesized compounds was also determined by the rotarod test. Derivatives exhibited favorable protection in both MES and scMET tests with high safety levels in NT test. The derivatives have proven significant activity in mice and could be suggested as potential anticonvulsant lead compounds. All leucine-chlorobenzoyl benzofuran-acetamide/propanamide/butanamide hybrid derivatives (6b, 7b, and 8b) showed significant anticonvulsant activity in MES model. Compound 8b also demonstrated potent anticonvulsant activity against scMET test. The compound 8b showed maximum activity and would be considered as a lead for further optimization as anticonvulsant agent. [GRAPHICS]

Synthesis and biological evaluation of 1-(benzofuran-3-yl)-4-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole derivatives as tubulin polymerization inhibitors

The key functions of microtubules and the mitotic spindle in cell division make them attractive targets for cancer therapy. In this study, a series of 1-(benzofuran-3-yl)-4-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazole derivatives was synthesized, and their antiproliferative activities against HCT116, HeLa, HepG2, and A549 cells were evaluated. 6-Methoxy-N-phenyl-3-(4-(3,4,5 trimethoxyphenyl)-1H-1,2,3-triazol-1-yebenzofuran-2-carboxamide (17g) exhibited the strongest antiproliferative activities, with IC50 values ranging from 0.57 to 5.7 mu M. Mechanistic studies showed that 17g inhibited tubulin polymerization, leading to the disruption of mitotic spindle formation, cell cycle arrest in the G2/M phase, and apoptosis of A549 cells. A docking study indicated that 17g was a good molecular fit at the colchicine binding site of tubulin. These results showed that 17g is a potential anticancer compound that is worthy of further development as a tubulin polymerization inhibitor.

New negative dielectric anisotropy liquid crystals based on benzofuran core

In this paper, new liquid crystal compounds with negative dielectric anisotropy were synthesised by regulating the substituents on the benzofuran ring. Their structures were confirmed by(1)H-nuclear magnetic resonance,(CNMR)-C-13 and mass spectra. The effects of substituent on the properties of liquid crystals were investigated. Compared with the reference compounds, the compounds with 5-ethoxy-6,7-difluorobenzofuran ring exhibit higher clearing points as well as the tendency of expansion of SmA phase range. The density functional theory calculation results reveal that the 6-ethoxy-7-fluorobenzofuran-based compound has smaller aspect ratio than that of the 5-ethoxy-6,7-difluorobenzofuran-based compound, which results in the diminish of the mesophase. Although the dielectric anisotropy of the 5-ethoxy-6,7-difluorobenzofuran-based compound is slightly lower than that of the reference compound, it has both the largest perpendicular and parallel dielectric constant.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6296-53-3, you can contact me at any time and look forward to more communication. Formula: C10H7NO4.
