Synthesis and Biological Evaluation of Quinoline-Based Novel Aurones

A new series of quinoline based aurones 7(a-n) has been synthesized and evaluated for their antibacterial, antifungal and antiquorum sensing activities. These novel aurones have been prepared directly from 2-chloro-1-(2,4-dihydroxyphenyl)ethan-1-one in one pot, by reacting it with differently substituted 2-chloroquinoline-3-carbaldehydes using activated barium hydroxide under solvent free grinding conditions. Structures of these novel aurones are in agreement with their IR, H-1-NMR, C-13-NMR and HRMS data. Some of these compounds have attributed a significant antiquorum sensing activity.

Ozonation of the dye Reactive Red 239 and biodegradation of ozonation products in a moving-bed biofilm reactor: Revealing reaction products and degradation pathways

The ozonation of the azo dye Reactive Red 239 (RR 239) was investigated in a bench-scale reactor. Decolorization and organic matter removal were monitored in batch assays. The toxicity of the dye and its ozonation products to the test-organism Aliivibrio fischeri was also assessed. Identification of ozonation products was performed using analytical techniques (GC-MSD and high resolution mass spectrometry). Ozonated and non-ozonated dye solutions were supplemented with organic matter (glucose) and nutrients sources and subjected to biological treatment in a moving-bed biofilm reactor (MBBR). Five experimental runs were conducted, varying the influent characteristics and monitoring organic matter removal and nitrification performance. Identification of residual compounds in the effluent was also performed. Color was very rapidly removed by ozonation, but the degree of mineralization achieved was rather low. Moreover, toxicity was completely removed after 4 min of ozone reaction. Based on the ozonation products, a two-way mechanism was proposed for the degradation of RR 239 by ozone. Further biological treatment in the MBBR revealed that the removal of organic matter (evaluated as COD) was not affected by the ozonation products. However, nitrification efficiency dropped significantly when the dye or the ozonated dye was fed to the bioreactor. Furthermore, inhibition of nitrite oxidizers resulted in partial nitrification and consequent accumulation of nitrite, which consisted of the main oxidized nitrogen specie in the reactor effluent. The identification of compounds resulting from the ozonation and biological treatment steps suggests that the partial inhibition of nitrifying organisms was possibly caused by triazine- and benzofuran-related organic compounds. Nevertheless, their adverse effect on nitrification was found to be reversible and practically ceased once these compounds were removed from the influent. Overall, the results revealed that the combination of ozonation and MBBR for the treatment of azo dye containing-wastewaters is promising but the ozone-based process should be optimized in order to enable the degradation of compounds inhibiting nitrification.

An in vitro study reveals the anti-obesity effects of 7-methoxy-3-methyl-5((E)-prop-1-enyl)-2-(3,4,5-trimethoxyphenyl)-2,3-dihydrobenzofuran from Myristica fragrans

Adipogenesis, the maturation process of preadipocytes, is closely associated with the development of obesity and other complex metabolic syndromes. Herein, we investigated the effect of 7- methoxy-3-methyl-5-((E)- prop-1-enyl)-2-(3,4,5-trimethoxyphenyl)-2,3-dihydrobenzofuran (TM), a benzofuran, isolated from the mace of Myristica fragrans Houtt on adipogenesis in 3T3-L1 preadipocytes to extrapolate whether this compound has any antiobesity potential. For this, 3T3-L1 preadipocytes were induced to differentiate in the presence of various concentrations of TM (1, 5, 10 mu M) and analyzed for triglyceride (TG) accumulation and the expression of proteins and genes involved in lipogenesis and lipolysis associated with adipogenesis. Results showed that TM significantly reduced TG accumulation and expression of marker proteins of adipocyte differentiation (pemxisome proliferator-activated receptor y, CCAAT/enhancer-binding protein a, and fatty acid-binding protein 4) and increased the secretion of glycerol in a dose-dependent manner. There was a significant dose-dependent decrease in the expression of fatty acid synthase, steamyl-CoA desaturase-1, sterol regulatory element-binding transcription factor 1c, and acetyl-CoA carboxylase 1 and an increase in carnitine palmitoyltransferase 1, acyl-CoA oxidase, and peroxisome proliferator-activated receptor a in TM treated cells. The phosphorylation of cAMP-activated protein kinase was also increased, which in turn activated the phosphorylation of acetyl-CoA carboxylase in mature adipocytes. Also, there was an increase in glucose uptake by TM, suggesting its insulinsensitizing potential. This is the first report on the anti-obesity effects of TM from Myristica fragrans on adipogenesis and lipid metabolism in 3T3-L1 adipocytes and demands detailed in vivo study for developing TM as antiobesity therapeutics.

Improved and Practical Synthesis of the Integrastatin Core

The new and versatile method for the synthesis of integrastatin core has been developed by the use of o-toluic acid and 2′-hydroxyacetophenone with NaH/sec-BuLi, followed by the reaction of dihydroisocoumarins with MeLi. The overall steps for the synthesis of integrastatin core was only 3 steps including the known method by the literature. The scope and limitations of substrates bearing the various substituents on the aromatic ring were investigated. The chemical yields by our approach are generally high and the current route enables us the rapid synthesis.

Palladium-Catalyzed Asymmetric [4+3] Cyclization of Trimethylenemethane: Regio-, Diastereo-, and Enantioselective Construction of Benzofuro[3,2-b]azepine Skeletons

The palladium-catalyzed asymmetric [4+3] cyclization of trimethylenemethane donors with benzofuran-derived azadienes furnishes chiral benzofuro[3,2-b]azepine frameworks in high yields (up to 98 %) with exclusive regioselectivities and excellent stereoselectivities (up to >20:1 d.r., >99 % ee). This catalytic asymmetric [4+3] cyclization of Pd-trimethylenemethane can enrich the arsenal of Pd-TMM reactions in organic synthesis.

The Fragment-Based Development of a Benzofuran Hit as a New Class of Escherichia coli DsbA Inhibitors

A fragment-based drug discovery approach was taken to target the thiol-disulfide oxidoreductase enzyme DsbA from Escherichia coli (EcDsbA). This enzyme is critical for the correct folding of virulence factors in many pathogenic Gram-negative bacteria, and small molecule inhibitors can potentially be developed as anti-virulence compounds. Biophysical screening of a library of fragments identified several classes of fragments with affinity to EcDsbA. One hit with high mM affinity, 2-(6-bromobenzofuran-3-yl)acetic acid (6), was chemically elaborated at several positions around the scaffold. X-ray crystal structures of the elaborated analogues showed binding in the hydrophobic binding groove adjacent to the catalytic disulfide bond of EcDsbA. Binding affinity was calculated based on NMR studies and compounds 25 and 28 were identified as the highest affinity binders with dissociation constants (K-D) of 326 +/- 25 and 341 +/- 57 mu M respectively. This work suggests the potential to develop benzofuran fragments into a novel class of EcDsbA inhibitors.

Pd(II)-Catalyzed, Bidentate Directing Group-aided Alkylation of sp(3)gamma-C-H Bonds: Access to 3-Alkylated Thiophene/Furan and Benzothiophene/Benzofuran Motifs

We report the Pd(II)-catalyzed bidentate directing group 8-aminoquinoline-aided sp(3)gamma-C-H alkylation of 3-methyl- thiophene/furan-2-carboxylic acid and 3-methyl- benzothiophene/benzofuran-2-carboxylic acid systems. While the 8-aminoquinoline-aided sp(3)gamma-C-H functionalization including arylation or amidation or amination of carboxylic acid derivatives are well known, however, the Pd(II)-catalyzed bidentate directing group 8-aminoquinoline-aided sp(3)gamma-C-H alkylation is not explored. Notably, 2- and/or 3-alkylated thiophene/furan and benzothiophene/benzofuran motifs are found in pharmaceutically active molecules. Accordingly, this work reveals the scope of the 8-aminoquinoline-aided sp(3)gamma-C-H alkylation method, and its usefulness by enriching the libraries of 3-alkylated thiophene/furan and benzothiophene/benzofuran motifs.
