The application of safe for humans and the environment Polyversum antifungal agent containing living cells of Pythium oligandrum for biotransformation of prochiral ketones

This report presents the whole-cell biotransformation of benzofuranyl-methyl ketone derivatives with the application of Polyversum antifungal agent containing Pythium oligandrum microorganism. Stereochemistry of the reduction of prochiral substrates was modified by the bioconversion conditions (concentration of reagents, a source of the carbon atom, biotransformation medium). In optimized conditions enantioselective process was noted. Secondary alcohols with excellent enantiomeric purity and high yields were obtained. The enantiomeric excess and conversion degree of 1-(benzofuran-2-yl)ethanol, 1-(7-ethylbenzofuran-2-yl)ethanol and 1-(3,7-dimethylbenzofuran-2-yl)ethanol were 99%/98.1%, 94%/94.4% and 99%/72.6%, respectively. In the presence of P. oligandrum, one of the enantiotopic hydrides of the dihydropyridine ring coenzyme is selectively transferred to a re side of the prochiral carbonyl group to give products with S configuration. This study demonstrates an inexpensive, eco-friendly approach in synthesis of optically pure benzofuran derivatives and can be an interesting alternative to organocatalysis. Furthermore, this method can be used in biotechnology processes due to its good chemical performance and a high degree of product isolation.

Synthesis, anticancer and antimicrobial evaluation of new benzofuran based derivatives: PI3K inhibition, quorum sensing and molecular modeling study

A new series of benzofuran derivatives has been designed and synthesized. The structures of the synthesized compounds have been confirmed by the use of H-1 NMR, C-13 NMR, 2D H-1-H-1 NOESY NMR, and IR. Anticancer activity is evaluated against Hepatocellular carcinoma (HePG2), mammary gland breast cancer (MCF-7), Epitheliod carcinoma cervix cancer (Hela) and human prostate cancer (PC3). Compounds 8, 9, and 11 showed the highest activity towards the four cell lines with an IC50 range of 8.49-16.72 mu M, 6.55-13.14 mu M and 4-8.99 mu M respectively in comparison to DOX (4.17-8.87 mu M).

Compounds 8, 9 and 11 showed good inhibitory activity against PI3Ka with IC50 values 4.1, 7.8, and 20.5 mu M, respectively in comparison to 6.18 mu M for the reference compound LY294002. In addition, activity of compounds 8 and 9 on cell cycle arrest and induction of apoptosis in different phases of MCF-7 cells were assessed and detected pre-G1 apoptosis and cell growth arrest at G2/M. Also, both extrinsic and intrinsic apoptosis in MCF-7 cells induced by compounds 8 and 9. Molecular docking, binding affinity surface mapping, and contact preference of the synthesized compounds 8, 9 and 11 against PI3K were estimated and studied computationally using molecular operating environment software (MOE) and showed good interaction with essential residues for inhibition Val851. In addition, antimicrobial activity was evaluated against gram positive isolates as Staphylococcus aureus and Bacillus cereus, gram negative isolate as Escherichia cob, Pseudomonas aeruginosa and antifungal potential against Candida albicans. Compound 17 showed outstanding anti Gram-positive activity with MIC values 8 and 256 mu g/mL. in Staphylococcus aureus and Bacillus cereus respectively. Also, compounds 15, 17, 18 and 21 showed good anti Gram-negative activity with MIC value 512 mu g/mL. for all compounds.

Biomimetic Oxidation of Benzofurans with Hydrogen Peroxide Catalyzed by Mn(III) Porphyrins

The modelling of metabolic activation of the benzofuran nucleus is important to obtain eco-sustainable degradation methods and to understand the related mechanisms. The present work reports the catalytic oxidation of benzofuran, 2-methylbenzofuran, and 3-methylbenzofuran by hydrogen peroxide, at room temperature, in the presence of different Mn(III) porphyrins as models of cytochrome P450 enzymes. Conversions above 95% were attained for all the substrates. The key step is the formation of epoxides, which undergo different reaction pathways depending on factors, such as the position of the methyl group and the reaction and work-up conditions used.

Spiroindolone Analogues as Potential Hypoglycemic with Dual Inhibitory Activity on alpha-Amylase and alpha-Glucosidase

Inhibition of alpha-amylase and alpha-glucosidase by specified synthetic compounds during the digestion of starch helps control post-prandial hyperglycemia and could represent a potential therapy for type II diabetes mellitus. A new series of spiroheterocyclic compounds bearing oxindole/benzofuran/pyrrolidine/thiazolidine motifs were synthesized via a 1,3-dipolar cyclo-addition reaction approach. The specific compounds were obtained by reactions of chalcones having a benzo[b]furan scaffold (compounds 2a-f), with a substituted isatin (compounds 3a-c) and heterocyclic amino acids (compounds 4a,b). The target spiroindolone analogues 5a-r were evaluated for their potential inhibitory activities against the enzymes alpha-amylase and alpha-glucosidase. Preliminary results indicated that some of the target compounds exhibit promising alpha-amylase and alpha-glucosidase inhibitory activity. Among the tested spiroindolone analogues, the cycloadduct 5r was found to be the most active (IC50 = 22.61 +/- 0.54 mu M and 14.05 +/- 1.03 mu M) as alpha-amylase and alpha-glucosidase inhibitors, with selectivity indexes of 0.62 and 1.60, respectively. Docking studies were carried out to confirm the binding interaction between the enzyme active site and the spiroindolone analogues.

Biocatalytic Strategy for Highly Diastereo- and Enantioselective Synthesis of 2,3-Dihydrobenzofuran-Based Tricyclic Scaffolds

2,3-Dihydrobenzofurans are key pharmacophores in many natural and synthetic bioactive molecules. A biocatalytic strategy is reported here for the highly diastereo- and enantioselective construction of stereochemically rich 2,3-dihydrobenzofurans in high enantiopurity (>99.9% de and ee), high yields, and on a preparative scale via benzofuran cyclopropanation with engineered myoglobins. Computational and structure-reactivity studies provide insights into the mechanism of this reaction, enabling the elaboration of a stereochemical model that can rationalize the high stereoselectivity of the biocatalyst. This information was leveraged to implement a highly stereoselective route to a drug molecule and a tricyclic scaffold featuring five stereogenic centers via a single-enzyme transformation. This work expands the biocatalytic toolbox for asymmetric C-C bond transformations and should prove useful for further development of metalloprotein catalysts for abiotic carbene transfer reactions.
