Benzofuran-2-acetic esters as a new class of natural-like herbicides

BACKGROUND In recent decades, the use of synthetic herbicides has been increasing, mainly in emerging countries. However, their intensive and indiscriminate application is a major cause of environmental pollution and human health injury. Therefore, there is an increasing need to develop new herbicides with safer toxicological and environmental profiles. A promising strategy is to synthesize new molecules containing the core of natural products as a template for the production of ‘bio-inspired’ or ‘natural-like’ herbicides. RESULTS The potential herbicidal activity of some benzofuran-2-acetic esters was assessed in vitro on Arabidopsis thaliana, a model species. All five molecules (M1-M5) showed significant phytotoxic activity, reducing both shoot and root system at low concentrations. In particular, methyl 2-(5-methoxybenzofuran-2-yl)hexanoate (M3) exhibited the highest phytotoxicity displayed against two crops and weeds, monocots (Zea mays L. and E. crus-galli) and dicots (Lactuca sativa L. and Amaranthus retroflexus L.). The M3 activity was also compared with glyphosate, a common herbicide, showing a lower but similar activity. Moreover, the results evidenced that M3 was more effective in post-emergency. CONCLUSION Readily synthesizable benzofuran-2-acetic esters possessing the benzofuran ring as ‘bio-inspired’ core, show significant herbicidal activity making them very efficient even at low concentrations. They can be sprayed in liquid form, and the addition of adjuvants can improve penetration through the leaf cuticle. These results confirm the importance of these molecules as models for the development of new natural-like herbicides. (c) 2019 Society of Chemical Industry

Cs2CO3-Mediated Rapid Room-Temperature Synthesis of 3-Amino-2-aroyl Benzofurans and Their Copper-Catalyzed N-Arylation Reactions

Cs2CO3 in dimethylformamide (DMF) is a perfect combination for the rapid room-temperature synthesis of 3-amino-2-aroyl benzofuran derivatives from the reaction of 2-hydroxybenzonitriles and 2-bromoacetophenones in good to excellent yields. Using this one-pot C-C and C-O bond-forming strategy, we prepared a series of 3-amino-2-aroyl benzofuran derivatives within a very short time (10-20 min). This method was also found suitable for gram-scale synthesis. Benzofurans (3) obtained by this Cs2CO3-mediated methodology were then further explored for the development of a tunable base- and ligand-free copper-catalyzed N-arylation methodology using arylboronic acids for the easy access of either mono- or bi-N-aryl derivatives of aminobenzofurans at ambient temperature. The reaction of 3 with malononitrile in DMF medium under microwave heating conditions provided highly fluorescent conjugated alkenes and novel pyridine-fused benzofurans.

Recent Updates on Anti-Inflammatory and Antimicrobial Effects of Furan Natural Derivatives

The furan nucleus is found in a large number of biologically active materials. In recent years, many natural furan derivatives were isolated and their biological effects were investigated. In this review, we focused on the anti-inflammatory and antimicrobial effects of some natural furans and discussed their effects on the immune system. Our investigation revealed that furan natural derivatives have effective antioxidant activities and exert regulatory effects on various cellular activities by modifying some signaling pathways such as MAPK (mitogen-activated Protein Kinase) and PPAR-gamma (peroxisome proliferator-activated receptor gamma). The antimicrobial activity of these natural compounds was performed through selective inhibition of microbial growth and modification of enzymes. Further studies are needed for isolation and detection of different furan derivatives from natural compounds and investigation of their precise mechanisms for revealing health beneficial effects of these compounds.

Lysophosphatidic Acid Receptor Agonism: Discovery of Potent Nonlipid Benzofuran Ethanolamine Structures

Lysophosphatidic acid (LPA) is the natural ligand for two phylogenetically distinct families of receptors (LPA(1-3), LPA(4-6)) whose pathways control a variety of physiologic and pathophysiological responses. Identifying the benefit of balanced activation/repression of LPA receptors has always been a challenge because of the high lability of LPA and the limited availability of selective and/or stable agonists. In this study, we document the discovery of small benzofuran ethanolamine derivatives (called CpX and CpY) behaving as LPA(1-3) agonists. Initially found as rabbit urethra contracting agents, their elusive receptors were identified from [S-35]GTP gamma S-binding and beta-arresting recruitment investigations and then confirmed by [H-3]CpX binding studies (urethra, hLPA(1-2) membranes). Both compounds induced a calcium response in hLPA(1-3) cells within a range of 0.4-1.5-log lower potency as compared with LPA. The contractions of rabbit urethra strips induced by these compounds perfectly matched binding affinities with values reaching the two-digit nanomolar level. The antagonist, KI16425, dose-dependently antagonized CpX-induced contractions in agreement with its affinity profile (LPA(1)>LPA(3)>>LPA(2)). The most potent agonist, CpY, doubled intraurethral pressure in anesthetized female rats at 3 mu g/kg i.v. Alternatively, CpX was shown to inhibit human preadipocyte differentiation, a process totally reversed by KI16425. Together with original molecular docking data, these findings clearly established these molecules as potent agonists of LPA(1-3) and consolidated the pivotal role of LPA(1) in urethra/prostate contraction as well as in fat cell development. The discovery of these unique and less labile LPA(1-3) agonists would offer new avenues to investigate the roles of LPA receptors. SIGNIFICANCE STATEMENT We report the identification of benzofuran ethanolamine derivatives behaving as potent selective nonlipid LPA(1-3) agonists and shown to alter urethra muscle contraction or preadipocyte differentiation. Unique at this level of potency, selectivity, and especially stability, compared with lysophosphatidic acid, they represent more appropriate tools for investigating the physiological roles of lysophosphatidic acid receptors and starting point for optimization of drug candidates for therapeutic applications.

A ZnI2-catalyzed regioselective cascade 1,4-conjugate addition/5-exo-dig annulation pathway for one-pot access to heterobiaryl frameworks

Facile access to pi-extended heterobiaryl compounds via a non-cross-coupling strategy has been achieved. In the presence of an inexpensive ZnI2 catalyst and versatile propargylamine and beta-naphthol (or beta-naphthylamine and beta-naphthyl mercaptan) starting materials, a variety of sterically hindered heterobiaryl frameworks can be easily obtained. The present catalytic system offers excellent selectivity, good-to-excellent product yields, and good functional group tolerance including, for instance, -CN, -COOH, -C(O)R, -Br and -Cl groups. This cyclization process is proposed to proceed via in situ generated alkynyl o-quinone methides (o-AQMs), following a cascade intermolecular 1,4-conjugate addition/5-exo-dig annulation/1,3-H shift pathway.

Bis(benzofurano)pyrrole and hybrid thienopyrrole derivatives for organic thin-film transistors

To develop new element blocks based on thienopyrroles (DTP) units, bis(benzofurano)pyrrole and hybrid thienopyrrole derivatives were synthesized by Buchwald-Hartwing amination methods. Optical absorption, cyclic voltammetry (CV), single-crystal X-ray diffraction analyses and organic thin-film transistor (OTFT) were employed to investigate the structure-activity relationships of the resulting pyrrole derivatives. It was found that the introduction of a benzofuran unit enhances the planarity and conjugation of heteroacenes leading to strong molecular aggregation and denser pi-pi stacking, resulting in better charge transport properties with the hole mobility of 0.025 cm(2)V(-1)s(-1) for the OTFTs.

Double-Carboxylation of Two C-H Bonds in 2-Alkylheteroarenes Using LiO-t-Bu/CsF

We describe the double-carboxylation of two C-H bonds (i.e., at the benzylic and the beta-positions) in 2-alkylheteroarenes using a combination of LiO-t-Bu and CsF. A diverse range of substrates, namely benzothiophene, thiophene, benzofuran, furan, and indole derivatives, are efficiently converted into the doubly carboxylated products. A variety of functionalities (i.e., methyl, methoxy, halogen, cyano, ester, ketone, and amide moieties) are well tolerated.

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.
