A phytochemical investigation on the 90% ethanol aqueous extract of the aerial part of Kopsia arborea led to the isolation of three new monoterpenoid indole alkaloids, kopsiarborines A-C (1-3). The new structures were elucidated by using spectroscopic data (NMR, IR, UV, and MS). The isolated alkaloids were tested in vitro for cytotoxic potentials against six human lung cancer cell lines (A549, ATCC, H446, H460, H292, and 95-D). As a result, alkaloids 1 and 2 exhibited significant cytotoxic activities against all the tested tumor cell lines with IC50 values less than 20 mu M.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 190786-44-8, Name is Bepotastine besilate, molecular formula is , belongs to indole-building-block compound. In a document, author is Qiu, Xiang, SDS of cas: 190786-44-8.

This work aims to achieve the co-immobilization of laccase and 2,2-binamine di 3 ethylbenzothiazolin-6-sulfonic acid (ABTS) to improve removal capability of the biocatalyst for pollutants while avoiding potential pollution caused by ABTS. The laccase was immobilized on magnetic chitosan nanoparticles modified with amino-functionalized ionic liquid containing ABTS (MACS -NIL) based on Cu ion chelation (MACS -NIL-Cu-lac). The carrier was characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, x-ray diffraction and etc., and electron paramagnetic resonance confirmed the mediator molecule ABTS on the carrier could also play the role of electron transmission. MACS -NIL-Cu-lac presented relatively high immobilization capacity, enhanced activity (1.7-fold that of free laccase), improved pH and temperature adaptability, and increased thermal and storage stability. The removal performance assay found that MACS -NIL-Cu-lac had a good removal efficiency with 100.0 % for 2,4-dichlorophenol in water at 25 degrees C, even when the concentration reached 50 mg/L. Reusability study showed that after six catalytic runs, the removal efficiency of 2,4-dichlorophenol by MACS-NIL-Cu-lac could still reach 93.20/0. Additionally, MACS -NIL-Cu-lac exhibited higher catalytic efficiencies with 100.0 %, 70.5 % and 93.3 % for bisphenol A, indole, and anthracene, respectively. The high catalytic performance in pure water system obtained by the novel biocatalyst co-immobilizing laccase and electron mediator ABTS showed greater practical application value.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1346572-63-1, Name is GSK503, molecular formula is C31H38N6O2, belongs to indole-building-block compound, is a common compound.

An effective and operationally simple method for the preparation of 1-(2-(sulfonamido)vinyl)indoles (SAV-indoles) by the Rh(II)-catalyzed reaction of 2,2-diaryl-2H-azirines with 1-sulfony1-1,2,3-triazoles has been developed. This method enables the stereoselective synthesis of a variety of 1,2,3-trisubstituted indoles having a Z configuration of the (1-aryl-2-(sulfonamido)vinyl) substituent. The reaction mechanism, supported by DFT calculations, involves the formation of 1,4-diazahexa-1,3,5-trienes, which rapidly cyclize to 2,2diaryl-1-sulfonyl-1,2-dihydropyrazines. These compounds can be isolated at an early stage of the reaction, but under prolonged heating they isomerize into 7aH-indolium ylides, followed by a barrierless 1,5-prototropic shift to SAV-indoles. The developed methodology was also applied to the preparation of 1,3′-biindoles from 2,2-diaryl-2H-azirines using 3-diazoindolin-2-imines instead of 1-sulfonyl-1,2,3-triazoles.

Acetylcholinesterase (AChE), one of the major therapeutic strategies for the treatment of Alzheimer’s disease (AD) is to increase the acetylcholine (ACh) level in the brain by inhibiting the biological activity of AChE. In this present work, a set of alkaloids and flavonoids against AChE enzyme were screened by computational chemistry techniques. The docking results showed that among alkaloid compounds the oxindole alkaloid namely mitragynine oxidole B (MITOB) and the indole alkaloids namely mitragynine (MIT) exhibited a good binding affinity towards AChE. These two compounds were then studied by molecular dynamics (MD) simulations. The binding free energy calculation and ligand-protein binding pattern suggested that both alkaloids could interact with AChE very well. Since MIT is the main alkaloid constituent of Mytragyna speciose leaves, this compound was isolated from M. speciose leaves and tested for anti-AChE activity. As a result, the isolated MIT had an inhibitory activity with pIC(50) value of 3.57. This finding provided that the mitragynine compound has the potential to be as a therapeutic agent for further anti-AChE drug development in treatment of Alzheimer’s disease. Graphic abstract

Key message An efficient protocol for large-scale in vitro propagation of Disanthus cercidifolius was developed. No genetic variation was detected among in vitro regenerants. This study aimed to develop an efficient micropropagation protocol for Disanthus cercidifolius Maxim., an ornamental shrub. Sprouting buds of two genotypes (‘Truba & apos; and ‘PdS & apos;) were used as an initial plant material. For the in vitro propagation experiment, the nodal segments were cultured on a MS medium supplemented with either N-6-benzyladenine (BA) or zeatin (both at 0.5-3 mg l(-1)). As a control, MS medium without growth regulators was used. The highest number of shoots per explant (6.95 +/- 0.33 in genotype ‘PdS & apos; and 7.93 +/- 0.41 in genotype ‘Truba & apos;) was achieved on a medium supplemented with 2 mg l(-1) BA. Half-strength WPM and half-strength MS medium supplemented with indole-3-butyric acid (IBA) (0.1-1 mg l(-1)) were tested for in vitro rooting of the shoots. Optimal rooting performance was achieved on a half-strength WPM containing 0.5 mg l(-1) IBA in genotype ‘PdS & apos;, and 0.1 mg l(-1) IBA in genotypes ‘Truba & apos;. The rooted plantlets were transferred ex vitro with 85% survival in genotype ‘PdS & apos; and 82.5% in genotype ‘Truba & apos;. Eighteen samples from each genotype were subjected to ISSR analysis and flow cytometry to assess plant genetic fidelity after micropropagation. Fifteen ISSR primers gave rise to monomorphic patterns indicating no detected genetic variation in regenerants. Flow cytometric analysis showed that the ploidy level in all tested in vitro regenerants remained stable. The micropropagation protocol optimized here represents a reliable and efficient method for the large-scale production of plants of the ornamental shrub Disanthus cercidifolius.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Nitha, P. R., once mentioned the application of 88150-47-4, Name is Amlodipine maleate, molecular formula is C24H29ClN2O9, molecular weight is 524.9481, MDL number is MFCD02259457, category is indole-building-block. Now introduce a scientific discovery about this category, Product Details of 88150-47-4.

Three metal-free organic D-pi-A dyes with benzothieno[3,2-b]indole as electron donor, cyanoacrylic acid as both electron acceptor and anchoring group with benzene (BID-1), thiophene (BID-2) and furan (BID-3) as pi-spacers were designed and synthesized for application in dye-sensitized solar cells (DSSCs). A planar and electron-rich heterocycle such as benzothieno[3,2-b]indole offers better backbone rigidity and improves charge transport properties in comparison to indolo[3,2-b]indole donor, previously reported from our group. Additionally, we synthesized a benzothieno[3,2-b]indole donor grafted with longer alkyl chains which efficiently prevented the approach of oxidized species in the electrolyte coming closer to semiconductor thereby arresting recombination. A power conversion efficiency of 4.11 % was achieved for dye-sensitized solar cells based on the furan pi-spacer benzothieno[3,2-b]indole dyeBID-3in comparison to the corresponding indolo[3,2-b]indole dye (IID-3) having an efficiency of 1.71 %. Detailed interfacial electrical measurements along with theoretical calculations disclosed the mechanism of back electron transfer and improvement in photovoltaic performance with respect to variation in both donor and pi-spacer.
