Electrosynthesis of a Biaurone by Controlled Dimerization of Flavone: Mechanistic Insight and Large-Scale Application

The electrochemistry of flavone (1) has been carefully investigated at glassy carbon cathodes in dimethylformamide containing 0.10 M tetra-n-butylammonium tetrafluoroborate as supporting electrolyte. In this medium, a cyclic voltammogram for a reduction of 1 exhibits a reversible cathodic process (E-pc = -1.58 V and E-pa = -1.47 V vs SHE) that is followed by an irreversible cathodic peak (E-pc = -2.17 V vs SHE). When water (5.0 M) is introduced into the medium, the first peak for 1 becomes irreversible (E-pc = -1.56 V vs SHE), and the second (irreversible) peak shifts to -2.07 V vs SHE. Bulk electrolyses of 1 at -1.60 V vs SHE afford flavanone, 2′-hydroxychalcone, 2′-hydroxy-3-phenylpropionate, and two new compounds, namely (Z)-1,6-bis(2-hydroxyphenyl)-3,4-diphenylhex-3-ene-1,6-dione (D1) and (Z)-2,2′-(1,2-diphenylethene-1,2-bis(benzofuran-3(2H))-one) (D2), obtained in significant amounts, that were characterized by means of H-1 and C-13 NMR spectrometry as well as single-crystal X-ray diffraction. Along with the above findings, we have proposed a mechanism for the electroreduction of 1, which has been further corroborated by our quantum mechanical study.

Current strategies for the development of fluorescence-based molecular probes for visualizing the enzymes and proteins associated with Alzheimer’s disease

One of the most prevalent forms of dementia is Alzheimer’s disease (AD) which causes severe memory impairment within humans. As such, research into the early diagnosis of AD is essential to help treatment, which has led to significant advances in fluorescence imaging. Unfortunately, modern medicine and biology place increasingly strict requirements for fluorescent probes. Therefore, over recent years, researchers have taken strides to develop novel fluorescent molecular probes, with properties suitable for modern clinical applications, including low phototoxicity, weak background interference, deep tissue penetration, enhanced specificity, strong binding affinity, and suitable permeability through the blood-brain barrier (BBB). From these recent research results, many novel concepts for molecular design and fluorescence techniques have emerged. Herein, we present strategies towards the development of probes capable of meeting the advanced clinical requirements. As part of this review, we will summarize the characteristic enzymes and proteins involved in AD progression, including Amyloid-beta, beta-secretase, tau protein, monoamine oxidases, and methionine sulfoxide reductase. Then, we will evaluate some of the early probes and summarize the recent advancements made in the design of probes suitable for clinical applications, from which several strategies have emerged, such as increasing permeability to the blood-brain barrier, enhancing specificity by boosting binding affinity, and improving optical properties for in vivo imaging, etc. Then to conclude current strategies for early stage diagnosis of AD will be presented, and the opportunities as well as the remaining challenges will be outlined.

Using the Cancer Dependency Map to Identify the Mechanism of Action of a Cytotoxic Alkenyl Derivative from the Fruit of Choerospondias axillaris

An extract prepared from the fruit of Choerospondias axillaris exhibited differential cytotoxic effects when tested in a panel of pediatric cancer cell lines [Ewing sarcoma (A-673), rhabdomyosarcoma (SJCRH30), medulloblastoma (D283), and hepatoblastoma (Hep293TT)]. Bioassay-guided fractionation led to the purification of five new hydroquinone-based metabolites, choerosponols A-E (1-5), bearing unsaturated hydrocarbon chains. The structures of the natural products were determined using a combination of 1D and 2D NMR, HRESIMS, ECD spectroscopy, and Mosher ester analyses. The purified compounds were evaluated for their antiproliferative and cytotoxic activities, revealing that 1, which contains a benzofuran moiety, exhibited over 50-fold selective antiproliferative activity against Ewing sarcoma and medulloblastoma cells with growth inhibitory (GI(50)) values of 0.19 and 0.07 mu M, respectively. The effects of 1 were evaluated in a larger panel of cancer cell lines, and these data were used in turn to interrogate the Project Achilles cancer dependency database, leading to the identification of the MCT1 transporter as a functional target of 1. These data highlight the utility of publicly available cancer dependency databases such as Project Achilles to facilitate the identification of the mechanisms of action of compounds with selective activities among cancer cell lines, which can be a major challenge in natural products drug discovery.

Chartspiroton, a Tetracyclic Spiro-naphthoquinone Derivative from a Medicinal Plant Endophytic Streptomyces

A novel 6/6/5/6 tetracyclic polyketide named chartspiroton (1) was isolated from a medicinal plant endophytic Streptomyces in Dendrobium officinale. The complete structure assignment with absolute stereochemistry was elucidated through spectroscopic data, computational calculations, and single-crystal X-ray diffraction. Chartspiroton features an unprecedented naphthoquinone derivative spiro-fused with a benzofuran lactone moiety.

Consequently, an excellent complement between the experimental data and the DFT based results was attained. The most dominant hyper conjugative interactions with associated stabilization energies of 67.52, 59.61 and 48.35 kcal/mol were found for BEINH , BFENH and BECBH respectively which may become the cause of their stability. The band gaps (E gap ) of BEINH , BFENH and BECBH were rationalized to be 3.814, 3.903 and 3.727eV respectively which can be ef ficiently polarized the chemical structures. The descending order of average linear polarizability for title compounds is as: BECBH BEINH >BFENH . It was conferred that highest value of 13 tot was obtained for BEINH as 3591.872 (a.u) and the smallest value was obtained for BECBH i.e. 2242.707 (a.u) among title compounds.

A comprehensive evaluation on pyrolysis behavior, kinetics, and primary volatile formation pathways of rice husk for application to catalytic valorization

Catalytic fast pyrolysis is a prospective and effective route to produce value-added products from rice husk (RH). Understanding the volatile compositions and its formation pathways as well as kinetics during RH pyrolysis is crucial and fundamental to regulate the quality of the target products since catalysts interact directly with primary volatiles. In this study, two pyrolysis coupled real-time volatile monitoring techniques (TG-FTIR and PyGC/TOF-MS) were employed to conduct comprehensive experiments for RH. The results showed that RH presented three mass loss and gaseous product evolution stages in the temperature range of 200 to 330 degrees C, 330 to 390 degrees C, and 390 to 600 degrees C, respectively. After speculating the formation pathways of the 24 main volatile species, it was indicated that 2,3-dihydro-benzofuran was the major product for hemicellulose, while 2-methoxy-4-(1-propenyl)-phenol was potentially a key active intermediate and very unstable during pyrolysis of lignin constituent in RH. In addition, pyrolysis of RH could be divided into two kinetic stages at cut-off point of 25% conversion. The first kinetic stage obeyed three-dimensional (D3) diffusion model and E-a was within 140-170 kJ/mol. In the secondary kinetic stage, Ea raised gradually to about 200 kJ/mol and pyrolysis reactions followed the second-order reaction model.

In the crystal packing of compound 1, each molecule engages in intermolecular hydrogen bonding, forming a centrosymmetric dimer with graph-set notation R-2(2) (8) and an O center dot center dot center dot O distance of 2.6073 (15) angstrom. There are weak C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions in the crystal packing of compound 2. The phthalide moiety in 2 is oriented roughly perpendicular to the ferrocene backbone, with a dihedral angle of 77.4 (2)degrees.

Development of a Robust Protocol for the Synthesis of 6-Hydroxybenzofuran-3-carboxylic Acid

Benzofuran scaffolds are fundamental moieties found in a variety of biologically active natural products and synthetic drugs. In the course of one of our development programs, we needed to develop a practical and cost-effective manufacturing approach to such a benzofuran scaffold. Here we report a highly robust four-step, one-pot process that provides access to a 6-hydroxybenzofuran-3-carboxylic acid structure. An H-1 NMR monitoring study allowed a better understanding of the overall sequence of events and the nature of the detected intermediates. After six steps, including the optimized tandem process, the desired hydroxylated benzofuran was obtained in 40% yield with a purity above 99%.
