Discovery of 3-(benzofuran-2-ylmethyl)-1H-indole derivatives as potential autophagy inducers in cervical cancer cells

In this manuscript we have documented the identification of a novel anticancer scaffold 3-(benzofuran-2-yl-methyl)-1H-indole. This scaffold has been designed by tweaking the known bisindolylmethane scaffold of natural products that display a wide range of biological activities. A series of 24 new conjugates have been synthesized and among them 5 derivatives exhibited IC50 values less than 40 mu M against two cervical cancer cell lines SiHa and C33a. Further mechanistic studies of two compounds 3eb and 3ec revealed that the toxicity of these compounds was due to the effective induction of autophagy mediated cell death. The autophagy induction was confirmed by the progressive conversion of LC3I to LC3II and downregulation of p62 in cervical cancer cells.

Hydrodeoxygenation of Benzofuran over Bimetallic Ni-Cu/gamma-Al2O3 Catalysts

Bimetallic NixCu(10-x)/gamma-Al2O3 catalysts (where x is the mass fraction of Ni) with different Ni/Cu mass ratios were prepared. The catalysts were characterized by X-ray diffractometry, N-2 adsorption-desorption, inductively coupled plasma mass spectrometry, X-ray photoelectron spectroscopy, H-2-temperature programmed reduction, and transmission electron microscopy. The effect of Ni/Cu mass ratio on benzofuran hydrodeoxygenation was investigated in a fixed-flow reactor. Cu addition improved the NiO reducibility. The strong interaction of Ni and Cu led to the formation of smaller and highly dispersed CuO and NiO species over gamma-Al2O3, which favors an improvement in catalytic activity. Among the as-prepared catalysts, the Ni5Cu5/gamma-Al2O3 showed the highest deoxygenated product yield (79.9%) with an acceptable benzofuran conversion of 95.2%, which increased by 18.3% and 16.9% compared with that of the monometallic Ni/gamma-Al2O3 catalyst. A possible reaction network was proposed, which would provide insight into benzofuran hydrodeoxygenation over the Ni5Cu5/gamma-Al2O3 catalyst.

Efficient Synthesis of Benzofurans via Cross-Coupling of Catechols with Hydroxycoumarins Using O-2 as an Oxidant Catalyzed by AlPO4-Supported Rh Nanoparticle

An efficient synthesis of benzofuran derivatives via the cross-coupling of catechols and hydroxycoumarins in H2O using O-2 as an ideal oxidant is reported. The above reaction allows the direct use of substrates without prefunctionalization, involves formation of C-C and C-O bonds in cascade manner, and affords H2O as the sole by-product. This simple and clean reaction is achieved by the development of an AlPO4-supported Rh nanoparticle catalyst. The catalyst was applicable to the synthesis of a wide range of benzofurans. We also successfully utilized this catalytic method for total synthesis of flemichapparin C, one of the naturally occurring coumestans exhibiting bioactivity. The combined functions of Rh nanoparticles and AlPO4 play a key role in this reaction where in situ generated o-benzoquinone by Rh nanoparticles is possibly an intermediate for nucleophilic addition to hydroxycoumarins on AlPO4.

Colorimetric Detection of Co2+, Cu2+, and Zn2+ by a Multifunctional Chemosensor in Aqueous Solution

A novel multifunctional colorimetric sensor HMBC ((E)-3-((2-hydroxy-3-methoxybenzylidene)amino)benzofuran-2-carboxamide), based on 3-aminobenzofuran-2-carboxamide and 2-hydroxyl-3-methoxylbenzaldehyde, was designed and synthesized. The chemosensor HMBC could sense Co2+, Cu2+, and Zn2+ by color changes from colorless to yellow. Limits of detection (0.38, 0.41, and 1.02 mu M) of HMBC for Co2+, Cu2+, and Zn2+ were much lower than the New Jersey Department of Environmental Protection (NJDEP) standard (1.70 mu M) for Co2+ and the WHO guidelines (31.5 mu M and 76 mu M) for Cu2+ and Zn2+. Significantly, HMBC could be applied for the quantification of Co2+, Cu2+, and Zn2+ in real samples. The sensing process of HMBC for Co2+, Cu2+, and Zn2+ was well demonstrated by H-1 NMR and UV-Visible titrations, Job plots, theoretical calculations, and ESI-mass spectroscopy.

Novel oxindole/benzofuran hybrids as potential dual CDK2/GSK-3 beta inhibitors targeting breast cancer: design, synthesis, biological evaluation, and in silico studies

The serine/threonine protein kinases CDK2 and GSK-3 beta are key oncotargets in breast cancer cell lines, therefore, in the present study three series of oxindole-benzofuran hybrids were designed and synthesised as dual CDK2/GSK-3 beta inhibitors targeting breast cancer (5a-g, 7a-h, and 13a-b). The N-1 -unsubstituted oxindole derivatives, series 5, showed moderate to potent activity on both MCF-7 and T-47D breast cancer cell lines. Compounds 5d-f showed the most potent cytotoxic activity with IC50 of 3.41, 3.45 and 2.27 mu M, respectively, on MCF-7 and of 3.82, 4.53 and 7.80 mu M, respectively, on T-47D cell lines, in comparison to the used reference standard (staurosporine) IC50 of 4.81 and 4.34 mu M, respectively. On the other hand, the N-1-substituted oxindole derivatives, series 7 and 13, showed moderate to weak cytotoxic activity on both breast cancer cell lines. CDK2 and GSK-3 beta enzyme inhibition assay of series 5 revealed that compounds 5d and 5f are showing potent dual CDK2/GSK-3 beta inhibitory activity with IC50 of 37.77 and 52.75 nM, respectively, on CDK2 and 32.09 and 40.13 nM, respectively, on GSK-3 beta. The most potent compounds 5d-f caused cell cycle arrest in the G2/M phase in MCF-7 cells inducing cell apoptosis because of the CDK2/GSK-3 beta inhibition. Molecular docking studies showed that the newly synthesised N-1-unsubstituted oxindole hybrids have comparable binding patterns in both CDK2 and GSK-3 beta. The oxindole ring is accommodated in the hinge region interacting through hydrogen bonding with the backbone CO and NH of the key amino acids Glu81 and Leu83, respectively, in CDK2 and Asp133 and Val135, respectively, in GSK-3 beta. Whereas, in series 7 and 13, the N-1-substitutions on the oxindole nucleus hinder the compounds from achieving these key interactions with hinge region amino acids what rationalises their moderate to low anti-proliferative activity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 591-11-7 help many people in the next few years. Product Details of 591-11-7.

From Alkynes to Heterocycles through Metal-Promoted Silylformylation and Silylcarbocyclization Reactions

Oxygen and nitrogen heterocyclic systems are present in a large number of natural and synthetic compounds. In particular, oxa- and aza-silacyclane, tetrahydrofuran, benzofuran, cycloheptadifuranone, cycloheptadipyrrolone, pyrrolidine, lactone, lactam, phthalan, isochromanone, tetrahydroisoquinolinone, benzoindolizidinone, indoline and indolizidine scaffolds are present in many classes of biologically active molecules. Most of these contain a C=O moiety which can be easily introduced using carbonylative reaction conditions. In this field, intramolecular silylformylation and silylcarbocyclization reactions may afford heterocyclic compounds containing a carbonyl functional group together with a vinylsilane moiety which can be further transformed. Considering these two aspects, in this review a detailed analysis of the literature data regarding the application of silylformylation and silylcarbocyclization reactions to the synthesis of several heterocyclic derivatives is reported.

Intercepted Retro-Nazarov Reaction: Syntheses of Amidino-Rocaglate Derivatives and Their Biological Evaluation as eIF4A Inhibitors

Rocaglates are a family of natural products isolated from the genus Aglaia which possess a highly substituted cyclopenta[b]benzofuran skeleton and inhibit cap-dependent protein synthesis. Rocaglates are attractive compounds due to their potential for inhibiting tumor cell maintenance in vivo by specifically targeting eukaryotic initiation factor 4A (eIF4A) and interfering with recruitment of ribosomes to mRNA. In this paper, we describe an intercepted retro-Nazarov reaction utilizing intramolecular tosyl migration to generate a reactive oxyallyl cation on the rocaglate skeleton. Trapping of the oxyallyl cation with a diverse range of nucleophiles has been used to generate over 50 novel amidino-rocaglate (ADR) and amino-rocaglate derivatives. Subsequently, these derivatives were evaluated for their ability to inhibit cap-dependent protein synthesis where they were found to outperform previous lead compounds including the rocaglate hydroxamate CR-1-31-B.

LC-MS/MS method for the quantification of new psychoactive substances and evaluation of their urinary detection in humans for doping control analysis

The constant legal adaptation of new psychoactive substances (NPS), challenges their evaluation in different fields. In sports, NPS are prohibited in competition with a reporting limit (RL) of 50 ng/mL for the parent compound or a metabolite. However, there is a lack of comprehensive methodologies and excretion studies for monitoring NPS. This work aims to develop an analytical methodology for the NPS quantification and to evaluate the suitability of monitoring the urinary parent stimulants after NPS misuse. A method for the quantification of 14 common NPS was developed and validated. The method was found to be linear in the range 1-1000 ng/mL, and was shown to be accurate and precise. A lowest limit of quantification (LLOQ) of 1 ng/mL was established for all analytes except for benzylpiperazine (5 ng/mL). The method was able to confirm the identity of the analytes at the LLOQ for most NPS. The methodology was applied to the quantification of the parent compound in urine samples collected from an observational study where several healthy volunteers (n >= 6 per drug) ingested active doses of mephedrone (MEPH), methylone (MDMC), 2,5-dimetoxy-4-ethylphenetylamine (2C-E), or 6-(2-aminopropyl)benzofuran (6-APB). It was observed that for MDMC and 6-APB, the quantification of the urinary parent drug at the current RL is a proper strategy for detecting their misuse. However, this strategy seems to be insufficient for evaluating MEPH and 2C-E misuse. Monitoring the most abundant metabolite of MEPH (4 ‘-carboxy-MEPH) and the reduction of the RL to 10 ng/mL for the 2C-E evaluation are proposed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 591-11-7. Category: benzofurans.
