Synthesis and Anticancer Activity of Novel Benzofurancarboxamides

In our present work, presented an efficient synthesis and anticancer activity evaluation of some novel benzofurancarboxamides. Our proposed approaches provide the possibility to design benzofurans diversity with a considerable chemical novelty. The synthesized substances were selected by the National Cancer Institute (NCI) Developmental Therapeutics Program for the in vitro cell line screening to investigate their anticancer activity. The compounds with significant levels of anticancer activities have been found that can be used for further optimization.

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 87-41-2, in my other articles.

Design, synthesis, and biological evaluation of novel 4H-chromen-4-one derivatives as antituberculosis agents against multidrug-resistant tuberculosis

A series of 4H-chromen-4-one derivatives obtained by scaffold morphing of the benzofuran compound, TAM16, were tested for antitubercular activity. Compound 8d was active against drug-sensitive and multidrug-resistant tuberculosis. A preliminary druggability evaluation showed that compound 8d displayed favorable mouse and human microsomal stability, low cytotoxicity, and acceptable oral bioavailability. An in vivo study indicated that compound 8d exhibited modest efficacy in an acute mouse model of TB after 3 weeks of treatment. Thus, 8d is a promising antituberculosis lead compound.

Optimization of the Reaction Conditions for the Synthesis of Dihydrobenzofuran Neolignans

We have optimized the experimental conditions for the silver(I)-promoted oxidative coupling of methyl p-coumarate (I) and methyl ferulate (II), which is the most frequently used methodology to synthesize the bioactive dihydrobenzofuran neolignans 1 ((+/-)-trans-dehydrodicoumarate dimethyl ester) and 2 ((+/-)-trans-dehydrodiferulate dimethyl ester). Most of the tested conditions affected the conversion (i.e., the consumption of I and II) and the selectivity (i.e., the percentage of I and II that was converted into 1 and 2, respectively), so the optimized conditions were the ones that afforded the best balance between conversion and selectivity. Silver(I) oxide (0.5 equiv.) is the most efficient oxidant agent amongst the silver(I) reagents that were tested to convert methyl esters I and II into compounds 1 and 2, respectively. Acetonitrile, which has not yet been reported as a solvent for this reaction, provided the best balance between conversion and selectivity, besides being greener than other solvents that are more often employed (e.g., dichloromethane and benzene). Under the optimized conditions, the reaction time decreased from 20 to 4 h without significantly impacting the conversion and selectivity.

The electronic properties of quercetin (Q)-pi-cyanoacrylic acid (CNA) dye molecules using heteroaromatic rings, namely cyclopentadiene (F1), furan (F2), pyrrole (F3), thiophene (F4), oxazole (F5), imidazole (F6), thiazole (F7), isoindene (FF1), benzofuran (FF2), indole (FF3), benzothiophene (FF4), benzoxazole (FF5), benzimidazole (FF6), and benzothiazole (FF7), as pi-linkers are studied for the first time using Time-Dependent Density Functional Theory (TDDFT) with dimethyl sulfoxide (DMSO) as solvent to predict their excitation energy, absorption wavelength, oscillator strength, light harvesting efficiency, and exciton binding energy. The charge transfer and charge regeneration in the ground and excited states of the dyes are established. The photon to electron energy transfer from the dye (quercetin) to the semiconductor (TiO2) surface is analyzed based on intramolecular charge transfer. The results of the electron transfer studies on these newly designed dyes could be used to enhance the performance of resulting dye-sensitized solar cells.

Palladium-catalyzed Tsuji-Trost-type reaction of benzofuran-2-ylmethyl acetates with nucleophiles

The palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd-2(dba)(3)/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(eta(3)-C3H5)Cl](2)/XPhos is more efficient. The regiochemical outcome shows that the nucleophilic substitution occurs only on the benzylic position of the eta(3)-(benzofuryl)methyl complex. The high to excellent yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2-substituted benzo[b]furans.
