Eighteen dihydroindolizino[8,7b]indole derivatives 4a-r were designed, synthesized and evaluated as new alpha-glucosidase inhibitors. These derivatives were synthesized by an efficient one-pot two-step reaction under mild condition. All the synthesized compounds were found to be more active than the standard drug acarbose (IC50 = 750.0 +/- 1.5 mu M) with IC50 values in the range of 107.2 +/- 1.0-275.4 +/- 1.5 mu M. Among the synthesized compounds, diethyl derivative 4o and dimethyl derivative 4 h exhibited the highest anti-alpha-glucosidase activities (IC50 = 107.2 +/- 1.0 and 118.0 +/- 0.7 mu M, respectively). Kinetic analysis of the compound 4o revealed that this compound is a competitive inhibitor for alpha-glucosidase with Ki value of 113 mu M. Furthermore, the docking study on the compounds 4o and 4 h revealed that these compounds interacted with the important residues in the active site of the homology model of alpha-glucosidase.

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.

Indole derivatives are important heterocycles in organic synthesis for serving as privileged building blocks for functional material and as key components in a lot of bioactive compounds. Propargylic alcohols, bearing alkynyl and hydroxyl functional groups, have emerged as promising feedstock materials for the construction of carbo- and heterocycles. Especially, in the last decade, the Lewis or Bronsted acid catalysed tandem annulations of propargylic alcohols to build structurally diverse indole derivatives have been well-investigated. In this review, we summarize two main synthetic strategies toward indole derivatives via the cascade reactions of propargylic alcohols: indole-ring formation involved tandem reactions and the direct function-alization of indole skeletons. We hope this review would help to develop new and more efficient protocols for the synthesis of indole-included N-heterocycles.

Indoles are an important nucleus of N-heterocycles found in many natural products, active pharmaceuticals, and functional materials. In addition, indoles have various reactive positions, each one with a different reactivity, which may be susceptible to different reactions. This characteristic makes them important substrates for further transformations. This paper deals with the methodologies published in the last ten years, which used metal-free conditions to prepare indoles starting from alkynes and nitrogen compounds.

To discover novel anticancer agents with potent and low toxicity, we designed and synthesized a range of new thiosemicarbazone-indole analogues based on lead compound 4 we reported previously. Most compounds displayed moderate to high anticancer activities against five tested tumor cells (PC3, EC109, DU-145, MGC803, MCF-7). Specifically, the represented compound 16f possessed strong antiproliferative potency and high selectivity toward PC3 cells with the IC50 value of 0.054 mu M, compared with normal WPMY-1 cells with the IC50 value of 19.470 mu M. Preliminary mechanism research indicated that compound 16f could significantly suppress prostate cancer cells (PC3, DU-145) growth and colony formation in a dose-dependent manner. Besides, derivative 16f induced G1/S cycle arrest and apoptosis, which may be related to ROS accumulation due to the activation of MAPK signaling pathway. Furthermore, molecule 16f could effectively inhibit tumor growth through a xenograft model bearing PC3 cells and had no evident toxicity in vivo. Overall, based on the biological activity evaluation, analogue 16f can be viewed as a potential lead compound for further development of novel anti-prostate cancer drug. (C) 2020 Elsevier Masson SAS.

A highly enantioselective tandem Michael addition of tryptamine-derived oxindoles to alkynones was developed by taking advantage of a chiral N,N-dioxide Sc(OTf)(3) catalyst. The reaction enables the facile preparation of enantioenriched spiro[pyrrolidine-3,3-oxindole] compounds, which provides a novel strategy for the synthesis of monoterpenoid indole alkaloids. As a demonstration, the asymmetric synthesis of strychnos alkaloids [(-)-tubifoline, (-)-tubifolidine, (-)-dehydrotubifoline] was achieved in 10-11 steps.

In an article, author is Poloznikov, A. A., once mentioned the application of 65-46-3, COA of Formula: https://www.ambeed.com/products/65-46-3.html, Name is Cytidine, molecular formula is C9H13N3O5, molecular weight is 243.2166, MDL number is MFCD00006545, category is indole-building-block. Now introduce a scientific discovery about this category.

The effect of indole-3-carbinol on the proliferation and migration of MDA-MB-231 breast-cancer cells and healthy MCF-10A breast-tissue cells has been studied. It was shown that indole-3-carbinol reliably reduced the proliferation and migration of MDA-MB-231 cells and does not significantly affect MCF-10A cells. The incubation of MDA-MB-231 tumor cells with 100 mu M indole-3-carbinol for 48 h resulted in a marked decrease in the expression of the Wnt cascade genes CCND1 (by 28%), Sp1 (by 44%), CDK6 (by 47%), as well as the EGFR and FASN genes (by 64 and 22%, respectively). Incubation of the MCF-10A cell line under the same conditions induced a noticeable decrease in the expression of only two genes, EGFR (by 16%) and CDK6 (by 9%). Indole-3-carbinol was also shown to display selective DNA demethylating activity in breast-tumor cells and to reverse the process of abnormal methylation and functional blockage of the antitumor WIF-1 gene. The obtained data indicate that drugs containing indole-3-carbinol as an active component can be potential regulators of epigenetic processes in the complex treatment of breast cancer and other tumors.
