Synthesis and biological activity of new bisbenzofuran-imidazolium salts

A series of novel bisbenzofuran-imidazolium salts were designed and prepared. The in vitro antitumor activity of these derivatives was evaluated against a panel of human tumor cell lines (A549, HL-60, MCF-7, SMMC-7721 and SW480). Results demonstrated that 2-methyl-benzimidazole ring and substitution of the imidazolyl 3 po sition with a 4-methoxyphenacyl or 2-naphthylacyl substituent were important for promoting cytotoxic activity. Notably, compound 23 was found to be the most potent compound with IC50 values of 0.64-1.47 mu M against five human tumor cell lines, and exhibited higher selectivity to MCF-7 and SW-480 cell lines with IC50 values 15.3-fold and 9.1-fold lower than DDP.

Benzofuran-isatin hybrids tethered via different length alkyl linkers and their in vitro anti-mycobacterial activities

A series of novel benzofuran-isatin hybrids 6a-m tethered through different length alkyl linkers propylene, butylene, pentylene and hexylene were designed, synthesized and evaluated for their in vitro anti-mycobacterial activities against both drug-susceptible and multi-drug resistant (MDR) Mycobacterium tuberculosis (MTB) and cytotoxicity towards VERO cells. All hybrids with acceptable cytotoxicity in VERO cells (CC50:64 to>1024 mu g/mL) also exhibited considerable anti-mycobacterial activities against both drug-susceptible and MDR-MTB strains with MIC in a range of 0.125-4 mu g/mL. The SAR indicated that the length of the linker played a pivotal role on the activity, and the longer linker could enhance the activity. The most active hybrid 6d (MIC:0.125 and 0.125 mu g/mL) was comparable to or better than rifampicin (MIC:0.5 mu g/mL) and isoniazid (MIC:0.06 mu g/mL) against MTB H(37)Rv, and was >256 folds more potent than rifampicin (MIC:64 mu g/mL) and isoniazid (MIC:>128 mu g/mL) against MDR-MTB strain, but was less active than TAM16 (MIC:<0.06 mu g/mL against the tested two strains). The hybrid 6d also showed low cytotoxicity towards VERO cell (CC50:128 mu g/mL), but it was inferior to TAM16 in metabolic stability and in vivo pharmacokinetic profiles. Interested yet?

Diastereo- and Atroposelective Synthesis of Bridged Biaryls Bearing an Eight-Membered Lactone through an Organocatalytic Cascade

We present herein an unprecedented stereoselective synthesis of bridged biaryls with defined axial and central chirality from readily available starting materials. This N-heterocyclic carbene-catalyzed method proceeds through propargylic substitution of azolium enolates followed by two-directional cyclization, as supported by DFT calculation. A range of benzofuran/indole-derived bridged biaryls bearing an eight-membered lactone are accessed with uniformly high stereoselectivity (>98:2 dr, mostly >98% ee).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 591-11-7, in my other articles.

Chemoenzymatic Synthesis of (-)-Ribisins A and B from Dibenzo[b,d]furan

cis-Dihydrodiols, derived from monocyclic aromatic compounds, are valuable chiral pool intermediates for the synthesis of cyclic natural products. A drawback of this approach, to the synthesis of polycyclic secondary metabolites, is that additional rings must be annulated. To date, relatively few chiral natural products have been synthesized from polycyclic arene cis-dihydrodiols. Fungal metabolites, (-)-ribisins A and B, have now been obtained by functional group manipulation of a tricyclic arene metabolite, obtained from toluene dioxygenase-catalyzed regioselective and stereoselective cis-dihydroxylations of dibenzo[b,d]furan. The synthetic sequences were marginally shorter than the alternative routes, using monocyclic arene cis-dihydrodiols, and required no carbon-carbon bond-forming reactions.

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 591-11-7 is helpful to your research. Name: 5-Methylfuran-2(5H)-one.

Synthesis and biological evaluation of a new series of benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides as potential alpha-glucosidase inhibitors

A series of new benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides 12a-n as potential anti-alpha-glucosidase agents were designed and synthesized. alpha-Glucosidase inhibition assay demonstrated that all the synthesized compounds 12a-n (half-maximal inhibitory concentration [IC50] values in the range of 40.7 +/- 0.3-173.6 +/- 1.9 mu M) were more potent than standard inhibitor acarbose (IC50 = 750.0 +/- 12.5 mu M). Among them, the most potent compound was compound 12c, with inhibitory activity around 19-fold higher than acarbose. Since the most potent compound inhibited alpha-glucosidase in a competitive mode, a docking study of this compound was also performed into the active site of alpha-glucosidase. In vitro and in silico toxicity assays of the title compounds were also performed.

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

Electrochemical Assessment of EC and ECE Mechanisms for Caffeic Acid in the Presence of Aromatic Amines

In this work, electrochemical behavior of caffeic acid (CA) in the absence and presence of aromatic amines such as 4-amino-1,3-dimethyluracil (4A-DMU), p-toluidine (p-TI) and sulfacetamide (SA) has been investigated using cyclic voltammetry technique in 0.15 M sodium acetate solution/ethanol (80:20, v/v) mixture. The effect of different parameters such as concentration and scan rate indicated that the oxidation mechanism of caffeic acid (CA) in the presence of aromatic amines can be EC and ECE. At the working electrode surface, CA is oxidized to correponding o-benzoquinone (CA(OX)) through two electrons and two protons process. The Michael-type addition reaction has occurred between o-benzoquinone and aromatic amines. In the second cycle, compared to CA oxidation peak, a new oxidation peak appear in negative potentials because of the electron-donating properties of amines. The cyclic voltammetry technique can recognize chemical and electrochemical processes in solution and electrode surface, respectively.
