R2R3-MYB transcription factor MYB51 is known to control indole glucosinolate (indole GSL) biosynthesis in Arabidopsis. Here, two copies of BoaMYB51 have been isolated in Chinese kale (Brassica oleracea var. alboglabra Bailey), designated BoaMYB51.1 and BoaMYB51.2, which exhibit overlapping but distinct expression levels among different organs and respond to signaling molecules in a similar pattern. It has been demonstrated a structural and functional conservation between BoaMYB51s and AtMYB51 by phylogenetic analysis, complementation studies and transient expression assay. To further investigate the transcriptional mechanism, we identified the transcriptional activation domain (TAD) and putative interacting proteins of BoaMYB51s by means of yeast (Saccharomyces cerevisiae) two hybrid. Using tobacco (Nicotiana benthamiana) transient expression assay, we confirmed that the carboxy-end is required for transcriptional activation activity of BoaMYB51s. In addition, several BoaMYB51-interacting proteins have been identified by yeast two-hybrid screening. These results provide important insights into the molecular mechanisms by which MYB51 transcriptionally regulates indole GSL biosynthesis.

Synthesis of N-alkyl indoles via 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ) mediated intramolecular oxidative decarboxvlative aromatization of N-alkylindoline-2-carboxylic acids is reported. The good compatibility of this process leads to the development of a mild and metal-free one-pot synthesis of N-alkyl indoles from alkyl halides and indoline carboxylic acid. The one-pot three-component synthesis of 1,4-bis((1H-indol-1-yl)methyl)benzene is also disclosed in satisfied yields.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 1124-11-4, Name is Tetramethylpyrazine, formurla is C8H12N2. In a document, author is Wang, Menglan, introducing its new discovery. Formula: https://www.ambeed.com/products/1124-11-4.html.

Indole scaffold synthesis relies primarily on oxidative C-H amination of N-protected alkenylanilines for C-N intramolecular cyclization reactions. Herein, for the first time, without N-protection, various readily prepared 2-alkenylanilines were transformed into the desired indole products in good yields by using K2S2O8 as oxidant in the presence of catalytic amounts of FeF2 . The K2S2O8/FeF2 system offers a direct and benign synthetic route to 3-arylindoles and it is applicable to a wide range of substituted indoles including drug intermediates.

A practical and scalable approach for the synthesis of 3-substituted indoles is delineated via hydride nucleophilic addition to 3-substituted-2-oxindoles. The reaction proceeds through reductive aromatization involving indolinium ion intermediate. A wide range of 3-functionalized indoles have been synthesized. The method is employed for the synthesis of 3,3′-bis-indoles and a dimeric 3-indole derivative. Moreover, this protocol is used to obtain naturally occuring amino acid tryptamine.

The increasing diversity of small molecule libraries is a major source for the discovery of new drug candidates. In terms of this trend, we report the synthesis of five series 5-bromosubstituted derivatives of indole phytoalexins Types A-E using a straightforward synthetic approach. Novel compounds were screened in vitro for antiproliferative/cytotoxic activity against seven human cancer cell lines by MTT assay. Evaluation of their antiproliferative potency showed that the activity of some analogues was better or comparable to that of cisplatin and at the same time the toxicity of these compounds on 3T3 cells was lower than that of cisplatin. We found that all 5-bromosubstituted analogues of indole phytoalexins Types A-E exhibited lower or approximately the same activities as previously studied corrensponding non-brominated compounds.

These protocols proceed without any hazardous solvents, toxic metal catalysts and harsh reaction conditions. In addition, low catalyst loading, good yield and excellent functional group tolerance are the key advantages of these protocols. The used catalyst and solvent-free approach make this strategy safe to our mother earth. For the first time reusability of humic acid was investigated and found that it can be recycled up to fifth run without any significant loss of its activity at the end of the reaction. Some bioactive molecules such as arundine, trisindoline and vibribdole A were easily synthesized in our lab by utilizing this designed strategy.

Indole moiety is often found in different classes of pharmaceutically active molecules having various biological activities including anticancer, anti-viral, anti-psychotic, antihypertensive, anti-migraine, anti-arthritis and analgesic activities. Due to enormous applications of indole derivatives in pharmaceutical chemistry, a number of conventional synthetic methods as well as green methodology have been developed for their synthesis. Green methodology has many advantages including high yields, short reaction time, and inexpensive reagents, highly efficient and environmentally benign over conventional methods. Currently, the researchers in academia as well as in pharmaceutical industries have been developing various methods for the chemical synthesis of indole based compounds via green approaches to overcome the drawbacks of conventional methods. This review reflects the last ten years developments of the various greener methods for the synthesis of indole derivatives by using microwave, ionic liq- uids, water, ultrasound, nanocatalyst, green catalyst, multicomponent reaction and solvent-free reactions etc. (please see the scheme below). Furthermore, the applications of green chemistry towards developments of indole containing pharmaceuticals and their biological studies have been represented in this review.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. Application In Synthesis of Cyproterone acetate, 427-51-0, Name is Cyproterone acetate, SMILES is C[C@@]12C(C(Cl)=C[C@]3([H])[C@]2([H])C[C@@]4(C)[C@@]3([H])CC[C@]4(OC(C)=O)C(C)=O)=CC([C@H]5[C@@H]1C5)=O, in an article , author is Ahmad, Shakeel, once mentioned of 427-51-0.

The unpredictable precipitation and water deficit conditions in semiarid regions significantly reduce the yield of summer maize. The exogenous application of plant growth regulators can be used as a strategy to enhance plant stress tolerance and improve the growth and yield of maize under semiarid conditions. Here, we studied the protective role of melatonin application on maize yield using grain filling rate and hormonal crosstalk in maize grains. In the first field experiment, seeds were soaked with melatonin at a concentration of 0 (SM0), 25 (SM1), 50 (SM2), and 75 mu M (SM3) mu M. In contrast, in the second experiment, melatonin was applied on the foliage at the ninth leaf stage at a concentration of 0 (FM0), 25 (FM1), 50 (FM2), and 75 (FM3) mu M. Our findings showed that melatonin treatments as seed soaking significantly increased single seed weight, seed filling rate in superior, medium and inferior seeds by regulating the hormone levels compared to foliar application. Application of melatonin significantly increased the zeatin+zeatin riboside (Z+ZR), indole-3-acetic acid (IAA), and gibberellic acid (GA) contents. However, it significantly inhibited the contents of abscisic acid (ABA) during the seed filling period. The content of Z+ZR, IAA, and GA was positively correlated with the maximum seed filling rate, seed weight, and mean filling rate in middle, superior and lower seeds, while the ABA was negatively correlated. The ABA content in inferior seeds was positively correlated with the maximum and mean seed filling rate. In semiarid regions, melatonin treatment of SM2 and FM2 significantly increased the dry matter per plant, 100-grain weight, seed filling rate, IAA, Z+ZR, GA contents, ear characteristics, and maize yield.
