Copper Catalyzed Oxidative Arylation of Tertiary Carbon Centers

We describe herein a Cu(OTf)(2) catalyzed oxidative arylation of a tertiary carbon-containing substrate including aryl malononitriles, 3-aryl benzofuran-2-ones, and 3-aryl oxindoles. In some cases, the nitrile groups of the aryl malononitriles undergo further reactions leading to lactones or imines. These reaction conditions are applicable for a range of arenes, including phenols, anilines, anisoles, and heteroarenes. Mechanistic studies support the formation of a cationic intermediate via a two-electron oxidation.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 87-41-2 is helpful to your research. Formula: C8H6O2.

Benzofuran pyran compound rescues rat and human osteoblast from lipotoxic effect of palmitate by inhibiting lipid biosynthesis and promoting stabilization of RUNX2

Obesity and ageing increases bone marrow fat which in turn is associated with lower bone mass. Marrow adipocytes by secreting cytokines, adipokines and free fatty acids change the bone marrow milieu and thus the number of osteoblasts. Palmitate is the common saturated fatty acid, an unavoidable ingredient we consume with food, which kindles cell apoptosis. Compound 4e is osteogenic in nature. We examine the effect of compound 4e in palmitate induced lipotoxicity in rat osteoblasts. Design of benzofuran Pyran hybrid compound (4e) was found to be effective in inhibiting palmitate induced cell apoptosis. In this study an in vitro model of palmitate was contrived. Anti-apoptotic effect of compound 4e was assessed by Annexin/PI and LDH (Lactate dehydrogenase) assay. Compound 4e also increased osteoblast differentiation and mineralization. It also increased expression of osteogenic markers (RUNX2 and BMP2), assessed by Real time PCR and immunofluorescence, which was impeded by palmitate. Acetyl Co-Carboxylase (ACC) and Fatty acid synthase (FAS), two prominent mediators of lipid biosynthesis were increased by palmitate exposure. Compound 4e modulated lipid biosynthesis by inhibiting ACC and FAS as reflected visually and after quantification of less lipid droplet formation suggesting that 4e is osteogenic and simultaneously anti-lipotoxic.

Singlet oxygenation of triquinacene, barrelene, and homobarrelene

The singlet oxygenation of three polycyclic hydrocarbons, triquinacene, barrelene and homobarrelene was studied. Triquinacene reacted by way of a perepoxide intermediate, transferring an oxygen atom to another triquinacene molecule to give exclusively the mono epoxide. Barrelene, on the other hand, underwent a rare homo-Diels-Alder reaction with O-1(2) to give the decomposition product from the initial tetracyclic 1,2-dioxolane leading to benzofuran. The latter reacted with O-1(2) in a [2 + 2] cycloaddition to give an unstable 1,2-dioxetane which collapsed to 2-formylphenyl formate. The latter was independently synthesized via singlet oxygenation of authentic benzofuran. Homobarrelene reacted in a similar fashion to give a homo-Diels product, decomposition of which led to a keto aldehyde which was characterized spectroscopically. Computational work confirms the barrelene and homobarrelene reactions with O-1(2) as concerted [pi(2)(s)+ pi 2(s)+ pi 2(s)] cycloadditions. (C) 2020 Elsevier Ltd. All rights reserved.

Cut and sew: benzofuran-ring-opening enabled cyclopentenone ring formation

A facile approach to the fully substituted cyclopentenones involving an unprecedented benzofuran-ring-opening is described. The cleavage of a benzofuran endocyclic C2-O bond proceeded smoothly in the absence of any transition metal catalyst or highly reactive organometallic reagent. Such benzofuran-ring-opening is delicately incorporated into an acid-catalyzed cascade process, orchestrating a novel synthetic strategy for complex cyclopentenones with excellent yields and diastereoselectivities.

alpha-Lithiobenzyloxy as a Directed Metalation Group in ortho-Lithiation Reactions

The alpha-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective alpha-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl alpha-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection of electrophiles including carboxylic esters and dihalosilanes or germanes, which afford interesting benzofuran, sila(germa)dihydrobenzofuran, and silachroman derivatives from simple aryl benzyl ethers.

Discovery of Diphenoxy Derivatives with Flexible Linkers as Ligands for beta-Amyloid Plaques

The highly rigid and planar scaffolds with pi-conjugated systems have been widely considered to be indispensable for beta-amyloid (A beta) binding ligands. In this study, a library of diphenoxy compounds with different types of more flexible linkers as A beta ligands were synthesized and evaluated. Most of them displayed good affinity (K-i < 100 nM) for A beta(1-42) aggregates, and some ligands even showed values of K-i less than 10 nM. Structure-activity relationship analysis revealed that modification on the linkers or substituents tolerated great flexibility, which challenged the long-held belief that rigid and planar structures are exclusively favored for A beta binding. Three ligands were labeled by iodine-125, and they exhibited good properties in vitro and in vivo, which further supported that this flexible scaffold was potential and promising for the development of A beta imaging agents.

Spiroindolone analogues bearing benzofuran moiety as a selective cyclooxygenase COX-1 with TNF-alpha and IL-6 inhibitors

To design and discover a new compound can used as a COX with TNF-alpha and IL-6 inhibitors is highly challenge. A series of spiroindolone-bearing benzofuran moieties were resynthesized from the chalcone-based benzo[b]furan with substituted isatin, and amino acids. The requisite spiroindolone analogues were tested for their potential inhibitory activities against lipid metabolizing enzymes such as cyclooxygenase COX-1, COX-2, and the release of pro-inflammatory cytokines interleukin IL-6, and tumor necrosis factor TNF-a. Among the tested compounds, 5a, 5c, 5h, 5i, 5l, and 5p exhibited COX-1 inhibitor selectively with percent of inhibition 40.81-83.4% and IC50 values ranging from 20.42 mu M to 38.24 mM. In addition, all the synthesized target compounds possessed lipopolysaccharide-induced TNF-alpha, and IL-6 expression with a varying degree of COX-1 inhibition. Compounds 5d, 5e, 5f, 5g, and 5k markedly inhibited TNF-alpha, and IL-6 release in WI-38 fibroblast cells. Molecular docking of the most effective and highly selective compounds were investigated and shown important binding mechanisms which could affect pro-inflammatory enzymes and cytokines via the inhibition of COX-1, COX-2, IL-6, and TNF-alpha.

A Comparative Study of the Anticancer Activity and PARP-1 Inhibiting Effect of Benzofuran-Pyrazole Scaffold and Its Nano-Sized Particles in Human Breast Cancer Cells

Breast cancer is considered the most common and deadly cancer among women worldwide. Nanomedicine has become extremely attractive in the field of cancer treatment. Due to the high surface to volume ratio and other unique properties, nanomaterials can be specifically targeted to certain cells and tissues to interact with the living systems. The strategic planning of this study is based on using the nanoprecipitation method to prepare nanoparticles BZP-NPs (3.8-5.7 nm) of the previously prepared benzofuran-pyrazole compound (IV) BZP which showed promising cytotoxic activity. The capacity of BZP and BZP-NPs to suppress the growth of human breast tumor MCF-7 and MDA-MB-231 cells was evaluated using MTT assay. The IC50 doses of BZP and BZP-NPs targeting normal breast cells MCF-12A exceeded those targeting the cancer cells by >1000-fold, demonstrating their reasonable safety profiles in normal cells. Furthermore, cell cycle analysis, apoptosis induction detection, assessment of p53, Bcl-2, caspase-3, and PARP-1 levels of BZP and its nano-sized-BZP-NPs particles were also evaluated. Although the obtained results were in the favor of compound IV in its normal-sized particles, BZP-NPs appeared as a hit compound which showed improved cytotoxicity against the tested human breast cancer cells associated with the induction of pre-G1 apoptosis as well as cell cycle arrest at G2/M phase. The increase in caspase-3 level, upregulation of p53, and downregulation of Bcl-2 protein expression levels confirmed apoptosis. Furthermore, ELISA results exhibited that BZP-NPs produced a more favorable impact as a PARP-1 enzyme inhibitor than the parent BZP.
