Silver-Mediated Synthesis of Substituted Benzofuran- and Indole-Pyrroles via Sequential Reaction of ortho-Alkynylaromatics with Methylene Isocyanides

A silver-mediated reaction between 2-ethynyl-3-(1-hydroxyprop-2-yn-1-yl)phenols or 2-ethyn-yl-3-(1-hydroxy-prop-2-yn-1-yl)anilines and methylene isocyanides has been developed. A sequential 5-endo-dig cyclization and [3 + 2] cycloaddition process is proposed. This synthetic strategy is atom- and step-efficient and applicable to a broad scope of substrates, allowing the synthesis of valuable substituted benzofuran- and indole-pyrroles in moderate to high yields.

(4+3) cycloadditions of allenyl ether-derived oxygen-stabilized oxyallyls with furans

(4 + 3) cycloadditions between allenyl ethers and furans are described. The reaction features an in situ formation of oxygen-stabilized oxyallyls via epoxidations of allenyl ethers in the presence of H2PO4-. The multiple interactions between the oxygen-stabilized oxyallyl species and H2PO4- were studied using DFT calculations for rationalization of the regio- and diastereoselectivity of this cycloaddition. The utilities of this cycloaddition have been demonstrated by converting the (4 + 3) cycloadduct into the cyclohepta[b]benzofuran skeleton of frondosin B in two steps.

Structurally Modified Cyclopenta[b]benzofuran Analogues Isolated from Aglaia perviridis

Four new cyclopenta[b]benzofuran derivatives based on an unprecedented carbon skeleton (1-4), with a dihydrofuran ring fused to dioxanyl and aryl rings, along with a new structural analogue (5) of 5”’-episilvestrol (episilvestrol, 7), were isolated from an aqueous extract of a large-scale re-collection of the roots of Aglaia perviridis collected in Vietnam. Compound 5 demonstrated mutarotation in solution due to the presence of a hydroxy group at C-2”’, leading to the isolation of a racemic mixture, despite being purified on a chiral-phase HPLC column. Silvestrol (6) and episilvestrol (7) were isolated from the most potently cytotoxic chloroform subtraction of the roots. All new structures were elucidated using 1D and 2D NMR, HRESIMS, IR, UV, and ECD spectroscopic data. Of the five newly isolated compounds, only compound 5 exhibited cytotoxic activity against a human colon cancer (HT-29) and human prostate cancer cell line (PC-3), with IC50 values of 2.3 mu M in both cases. The isolated compounds (1-5) double the number of dioxanyl ring-containing rocaglate analogues reported to date from Aglaia species and present additional information on the structural requirements for cancer cell line cytotoxicity within this compound class.

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 174775-48-5, in my other articles.

Discovery of Potent Small-Molecule SIRT6 Activators: Structure-Activity Relationship and Anti-Pancreatic Ductal Adenocarcinoma Activity

SIRT6 activation is thought to be a promising target for the treatment of many diseases, particularly cancer. Herein, we report the discovery of a series of new small-molecule SIRT6 activators. Structure-activity relationship analyses led to the identification of the most potent compound, 2-(1-benzofuran-2-yl)-N-(diphenylmethyl) quinoline-4-carboxamide (12q), which showed an EC1.5 value of 0.58 +/- 0.12 mu M and an EC50 value of 5.35 +/- 0.69 mu M against SIRT6-dependent peptide deacetylation in FLUOR DE LYS assay. It exhibited weak or no activity against other HDAC family members as well as 415 kinases, indicating good selectivity for SIRT6. 12q significantly inhibited the proliferation and migration of pancreatic ductal adenocarcinoma (PDAC) cells in vitro. It also markedly suppressed the tumor growth in a PDAC tumor xenograft model. This compound showed attractive pharmacokinetic properties. Overall, 12q could be a good lead compound for the treatment of PDAC, and it is worthy of further study.

A benzofuran-beta-alaninamide based turn-on fluorescent chemosensor for selective recognition of Fe3+ ions

A benzofuran-beta-alaninamide based chemosensor, 3-(3-((4-methylbenzyl)amino)propanamido)benzofuran-2-carboxamide (BAA), was designed and synthesized for selective detection of Fe3+ ions. The binding ability of BAA towards Fe3+ in DMSO/H2O solution (9/1, v/v) has been studied by UV-vis absorption and fluorescence spectroscopy. Interestingly, the probe BAA exhibits an excellent turn-on fluorescence enhancement at 424 nm with an excitation wavelength of 290 nm. The quantum yield was determined to be 0.248 for BAA and 0.447 for the iron complex. The limit of detection (LOD) was calculated to be 1.3 mu M and 0.067 mu M by UV-vis absorption and fluorescence methods respectively. These values are much lower than that of US Environmental Protection Agency guidelines for drinking water (5.37 mu M). Job’s plot measurement evidenced the 2 : 1 binding stoichiometry for the complex formed between BAA and Fe3+. Moreover, the binding interaction of BAA towards Fe3+ was confirmed by density functional theory (DFT) studies. Finally, the real sample analysis proved that the probe BAA was more suitable for the detection of Fe3+.

Benzofuran-isatin hybrids and their in vitro anti-mycobacterial activities against multi-drug resistant Mycobacterium tuberculosis

A series of benzofuran-isatin hybrids 6a-n and 7a-g linked by alkyl linkers were designed and synthesized. Among them, hybrids 6a-1 and 7a-g were assessed for their in vitro anti-mycobacterial activities against two multi-drug resistant Mycobacterium tuberculosis (MDR-MTB) strains and the cytotoxicity towards CHO cells. The preliminary results indicated that all hybrids (MIC: 0.125-16 mu g/mL) showed excellent activity against the tested MDR-MTB strains, and low cytotoxicity (CC50: 64->512 mu g/mL) towards CHO cells. Among them, hybrid 7e (MIC: 0.125 and 0.25 mu g/mL) was highly active against the tested two MDR-MTB strains, which was 8-16 folds better than ciprofloxacin (MIC: 1 and 4 mu g/mL), >= 512 folds more potent than rifampicin (MIC: 64 and > 128 mu g/mL) and isoniazid (MIC: >128 mu g/mL), but it was less active than TAM16 (MIC: <0.06 mu g/mL). Moreover, the hybrid 7e (CC50: 128 mu g/mL) also showed low cytotoxicity towards CHO cells, and high selectivity index (1,024). However, the metabolic stability and in vivo pharmacokinetic profiles of hybrid 7e were inferior to TAM16, so it still needs to be modified so as to get the optimized hybrid for potential use in mycobacterial treatment.

CHEMICAL COMPOSITION OF BIOLOGICAL ACTIVE EXTRACTS OF Tapirira guianensis (ANACARDIACEAE)

This work describes the chemical composition of MeOH seeds and flowers extracts of Tapirira guianensis, a known tree that occurs in the Brazilian Atlantic forest. The CH2Cl2 soluble fraction of seeds extract was submitted to chromatographic procedures to obtain a mixture of new alkenyl dihydrobenzofuranoids which were identified as 2-[(10’Z)-dodec-10′-enyl]-dihydro-1-benzofuran-5-ol, 2-[(10’Z)-tridec-10′-enyl]-dihydro-1-benzofuran-5-ol e 2-[(10’Z)-pentadec-10′-enyl]-dihydro-1-benzofuran-5-ol (1 – 3) besides ss-sitosterol. From the EtOAc soluble fraction of flowers MeOH extract quercetin, quercitrin and gallic acid were obtained by chromatographic techniques. The fatty acid composition of oils from leaves and seeds were also determinate and the leaves’ oil is composed by 63.94% of saturated and 36.04% of unsaturated fatty acids while in the seeds the oil present 42.13% of saturated and 57.87% of unsaturated. All compounds and derivatives were identified by their spectrometric data analysis. The brine shrimp test of the extracts showed the seed CH2Cl2 and the EtOAc and BuOH soluble fractions of the flowers were actives and, the alkyl phenols are the responsible for this moderate activity. The antioxidant tests of the extracts indicated EtOAc soluble fraction of MeOH extract of flowers showed better results possibly due the presence of flavonoids and gallic acid.

Unusual structural changes as a result of weathering benzofuran-based diarylethenes in simulated sunlight

While the products that result from photochemical degradation of thiophene-based diarylethenes have been documented, those from the benzofuran counterparts have been less extensively studied. In this article, we present two unusual and yet to be reported degradation products of a dialkoxybenzofuran derivative, characterized by a combination of spectroscopy techniques and X-ray crystallography. We show that these products are generated by due to the specific substitution position of the alkoxy groups on the benzofuran heterocycle. We also propose reasonable mechanisms for the degradation pathways and products formation, which are supported by equivalent studies using isomeric monoalkoxy versions.
