Design, synthesis, and biological activity of a novel series of benzofuran derivatives against oestrogen receptor-dependent breast cancer cell lines

A docking study of a novel series of benzofuran derivatives with ER alpha was conducted. In this study, we report the synthesis of a novel series of benzofuran derivatives and evaluation of their anticancer activity in vitro against MCF-7 human breast cancer cells, as well as their potential toxicity to ER-independent MDA-MB-231 breast cancer cells, human renal epithelial HEK-293 cells, and human immortal keratinocytes (HaCaT cells) by using the MTT colorimetric assay. The screening results indicated that the target compounds exhibited anti-breast cancer activity. The target compound 2-benzoyl-3-methyl-6-[2-(morpholin-4-yl)ethoxy]benzofuran hydrochloride (4e) exhibited excellent activity against anti-oestrogen receptor-dependent breast cancer cells and low toxicity. The preliminary structure-activity relationships of the target benzofuran derivatives have been summarised. In conclusion, the novel benzofuran scaffold may be a promising lead for the development of potential oestrogen receptor inhibitors.

An efficient synthesis, structural (SC-XRD) and spectroscopic (FTIR, 1HNMR, MS spectroscopic) characterization of novel benzofuran-based hydrazones: An experimental and theoretical studies

Herein, the benzofuran-based hydrazones derivatives such as N’-(1-(benzofuran-2-yl)ethylidene)iso-nicotinohydrazide(BEINH), N’-(1-(benzofuran-2-yl)ethylidene)nicotine-hydrazide (BFENH ) and N’-(1-(benzofuran-2-yl)ethylidene)-2-chlorobenzohydrazide (BECBH )were synthesized and characterized us-ing FTIR, 1HNMR, MS spectroscopic and SC-XRD techniques. Furthermore, the structural geometrical parameters, vibrational bands, natural bond orbitals (NBOs), natural population analysis (NPA), molec-ular electrostatic potential (MEP), linear and nonlinear optical (NLO) properties of the BEINH , BFENH and BECBH were rationalized applying B3LYP level of density functional theory (DFT) inclusive of 6-311 thorn G(d,p) basis set. 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. The overall decreasing order of 13 tot was observed as: BEINH > BFENH > BECBH . Additionally, NLO properties of title compounds were found larger than reference material. (C) 2020 Elsevier B.V.

Potassium tert-butoxide mediated aerobic hydroxylation of arylboronic acids: an application towards the synthesis of (E)-phenoxy acrylates

The first example of potassium tert-butoxide mediated aerobic hydroxylation of arylboronic acids is described. A variety of arylboronic acids bearing both electron donating and withdrawing substituents successfully participated in the reaction and furnished phenols in good yields. This strategy also provides access to one pot synthesis of (E)-3-phenoxy acrylates from arylboronic acids and propiolates. The solvent plays an important role and a binary solvent system comprising CH3CN/THF is found to be the best.

Investigation of Anticancer Agents fro the Bark of Gyrinops versteegii (GILG.) Domke from Lombok Island

This study is part of a research collaboration between Kyoto University and The University of Mataram, aiming to identify and to utilize the agarwood plants, i.e., Gyrinops versteegii from Indonesia. The study, specifically, aims to discover anticancer agents from the bark of G. versteegii from Lombok Island of Indonesia. There were three provenances of G. versteegii observed, namely Soyun, Pantai, and Buaya. Based on the Brine Shrimp Lethality Test (BSLT), G. versteegii Buaya showed the highest cytotoxicity with LC50 45,94 mu g/ml. Meanwhile, G. versteegii Soyun and Pantai have LC50 75.86 mu g/mL and 56.36 mu g/mL respectively. A phytochemical study showed that the methanol extract of G. versteegii Buaya containing compounds from the group of alkaloid, flavonoid, steroid, triterpenoid, and saponin. The methanol extracts fractionated using Vacuum Liquid Chromatography into 10 fractions (F1-F10) and then retested BSLT. Among the fractions, F2 showed the best potency as an anticancer with LC50 64,12 mu g/mL. Based on the GC-MS analysis, the cytotoxicity from both methanol extract and F2 is predicted to be influenced by the same compounds, namely, 1,4-Benzenediol, 2-methyl, Pyridoxylamine, 2,3-Dimethylhydroquionone, Tetramethyl-p-benzoquinone and Benzofuran. Overall the bark of G. versteegii from Lombok island has great potency as an anticancer.

Unitary coupled cluster ground- and excited-state molecular properties

A scheme for the calculation of molecular properties within the framework of unitary coupled-cluster (UCC) theory in both the electronic ground and excited states is presented. The scheme is based on an expectation-value ansatz, similar to the equation-of-motion coupled-cluster method or the intermediate state representation (ISR) approach of the algebraic-diagrammatic construction (ADC) scheme. Due to the UCC ansatz, the resulting equations cannot be given by closed-form expressions but need to be approximated. Explicit expressions for the expectation value of a general one-particle operator correct through second order in perturbation theory have been derived and coded for the electronic ground state as well as for excited states of predominant single-excitation character. The resulting equations are shown to be equivalent to those of the second-order ADC/ISR procedure. As first computational tests, the second-order UCC method (UCC2) and the one employing third-order amplitudes (also eigenvectors) together with the second-order density matrix, denoted as UCC3(2), are applied to the calculation of dipole moments for a series of small closed- and open-shell systems as well as 4-cyanoindole and 2,3-benzofuran and compared to full configuration interaction or experimental results. For the aromatic organic molecules, the UCC2 method is shown to be sufficient for the ground-state dipole moment, whereas the UCC3(2) scheme is superior for excited-state dipole moments.

Quantum Tunneling Mediated Interfacial Synthesis of a Benzofuran Derivative

Reaction pathways involving quantum tunneling of protons are fundamental to chemistry and biology. They are responsible for essential aspects of interstellar synthesis, the degradation and isomerization of compounds, enzymatic activity, and protein dynamics. On-surface conditions have been demonstrated to open alternative routes for organic synthesis, often with intricate transformations not accessible in solution. Here, we investigate a hydroalkoxylation reaction of a molecular species adsorbed on a Ag(111) surface by scanning tunneling microscopy complemented by X-ray electron spectroscopy and density functional theory. The closure of the furan ring proceeds at low temperature (down to 150 K) and without detectable side reactions. We unravel a proton-tunneling-mediated pathway theoretically and confirm experimentally its dominant contribution through the kinetic isotope effect with the deuterated derivative.

Tuning the optoelectronic properties of vinylene linked perylenediimide dimer by ring annulation at the inside or outside bay positions for fullerene-free organic solar cells

Among various perylenediimide (PDI)-based small molecular non-fullerene acceptors (NFAs), PDI dimer can effectively avoid the excessive aggregation of single PDI and improve the photovoltaic performance. However, the twist of perylene core in PDI dimer will destroy the effective conjugation. Thus, ring annulation of PDI dimer is a feasible method to balance the film quality and electron transport, but the systematic study has attracted few attentions. Herein, we choose a simple vinylene linked PDI dimer, V-PDI2, and then conduct further studies on the structure-property-performance relationship of four kinds of derived fused-PDI dimers, namely V-TDI2, V-FDI2, V-PDIS2 and V-PDISe2 respectively. The former two are incorporated thianaphthene and benzofuran at the inside bay positions, and the latter two are fused thiophene and selenophene at the outside bay positions, respectively. Theoretical calculations reveal the inside- and outside-fused structures largely affect the skeleton configuration, the former two tend to be planar structure and the latter two maintain the distorted backbone. The photovoltaic characterizations show that the inside-fused PDI dimers offer high open circuit voltage (V-OC), while the outside-fused PDI dimers afford large short-circuit current density (J(SC)). This variation tendency results from the reasonably tunable energy levels, light absorption, molecular crystallinity and film morphology. As a result, PBDB-T:V-PDISe2 device exhibits the highest power conversion efficiency (PCE) of 6.51%, and PBDB-T:V-FDI2 device realizes the highest V-OC of 1.00 V. This contribution indicates that annulation of PDI dimers in outside or inside bay regions is a feasible method to modulate the properties of PDI-based non-fullerene acceptors.
