A BrOnsted acid catalysed regiodivergent phosphorylation of 2-indolylmethanols with diarylphosphine oxides has been established, which provides a brand-new strategy for accessing highly functionalized phosphorus-containing indoles with structural diversity. Under the catalysis of HOTsH2O, 2-indolylmethanols undergo regioselective benzylic phosphorylation at room temperature to afford benzylic site phosphorylated indoles in good to high yields (29 examples, up to 98% yield), while C3-phosphorylated indoles are obtained in the presence of HOTf under heating conditions (16 examples, up to 83% yield). Preliminary mechanistic studies suggest that C3-phosphorylated indoles are possibly obtained partially from direct C3-phosphorylation and dominantly from a tandem benzylic phosphorylation/[1,3]-P migration/isomerization sequence from 2-indolylmethanols. Furthermore, the acidity of the BrOnsted acid and the reaction temperature play a vital role in the [1,3]-P migration of benzylic phosphorylated indoles to form C3-phosphorylated indoles. This protocol serves as a good example for regioselective benzylic functionalization of 2-indolylmethanols.

In the Yangtze Valley of China, Pyrus pyrifolia is known by the name sand pear and often suffers abnormal, early leaf senescence and premature defoliation, which causes serious yield loss and poor fruit quality. In this study, the relationship of Alternaria alternata with abnormally senesced leaves (ASLs) was analyzed by physiological and molecular method. Using data from the P. pyrifolia cultivars ‘Huanghua’ and ‘Suisho’, we found that A. alternata inoculation caused early leaf senescence. Restricted foliar nutrient redistributions were observed in ASLs, such as nitrogen (N) and phosphorus (P). Higher abscisic acid (ABA) levels were induced in the tissues of the leaf mesophyll, veins and stalks of ASLs, and higher concentrations of indole-3-acetic acid (IAA) and H2O2 were induced in the tissues of leaf mesophylls and veins of ASLs, while an opposite trend was observed in the tissues of leaf veins. Quantitative real-time PCR (qRT-PCR) consistently demonstrated that ASLs upregulated the expression of ABA biosynthesis genes (e.g., PyNCED3, PyZEP and PyAAO3), and the catabolism gene (PyABA8 ‘ OH), whereas PyBG and PyDXS showed opposite trends. Based on the leaf senescence database (LSD) 3.0, 42 senescence-associated genes (SAGs) that induced differential expression by A. alternata inoculations were enriched for P. pyrifolia cv. ‘Hongfeng’, which has high susceptibility to A. alternata and readily exhibits early leaf senescence. These results showed that A. alternata infection is one of major factors for abnormal leaf senescence and ABA signaling involved in this pathogenic process.

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 530-78-9, in my other articles.

Indole is a typical nitrogen-containing aromatic pollutant in coking wastewater, and it can be used for the microbial production of indigo, one of the oldest dyestuffs. In this study, the activated sludge system bioaugmented with two indigo-producing bacterial strains, wild strain Comamonas sp. MQ and recombinant Escherichia coli (ND_IND), was constructed to investigate indigo bioproduction from indole. During the operation, the bioaugmentation could promote the production of indigo, especially in early stages, and the indigo yields gradually increased from 17.5 +/- 0.4 to 44.3 +/- 0.5 mg/L with the increase of influent indole (80 to 282 mg/L). Illumina MiSeq sequencing revealed that the microbial community could have a noticeable shift driven by the bioaugmentation and high indole pressure. The indigenous bacteria could be more responsible for indigo production, and the dominant genera Comamonas, Diaphorobacter, Paracoccus, Aquamicrobium, Pseudomonas, and Truepera could be the key functional taxa. Based on FAPROTAX (Functional Annotation of Prokaryotic Taxa) analysis, the nitrogen metabolism-related functional groups could play important roles in indole biotransformation and indigo biosynthesis. This study should provide insights into microbial production of indigo by microbial communities.

Catalytic aminomethylation of pyrrole and indole with N,N,N’,N’-tetramethylmethanediamine in the presence of 5 mol % of ZrOCl2 center dot 8H(2)O proceeds selectively at the positions 2, 5 of pyrrole and 1, 3 of indole. Carbazole under the same conditions affords 3-formyl-9-aminomethyl derivative. The reaction in the presence of 5 mol % of K2CO3 occurs as monoaminomethylation: for pyrrole at the position 2, for indole at the position 3, and for carbazole at the nitrogen atom of the substrate.

In humans, the over-expression of Mcl-1 protein causes different cancers and it is also responsible for cancer resistance to different cytotoxic agents. Thus, discovery of potential inhibitors of Mcl-1 is very important and both the pharmaceutical industry and academia are looking at it in the quest for new anticancer drugs. In the present study, different molecular modelling techniques such as recursive partitioning, Bayesian classification, structural and physico-chemical interpretation analysis and pharmacophore mapping were employed in order to identify the crucial structural fingerprints important for the optimization of 143 indole derivatives as Mcl-1 inhibitors. These modelling studies emphasize that hydrophobic naphthyl rings, methyl-substituted 1H-pyrazole moiety, N(1)-tethered morpholinoethyl group, chloro substitutions at the 6th position of indole nucleusetc.are beneficial for Mcl-1 binding. Finally, statistically validated classical QSAR and machine learning-based models were also developed for screening and prediction of different indole derivatives as Mcl-1 inhibitors. The modelling analyses will help medicinal chemists to design potent Mcl-1 inhibitors in future. Thus, the present study was an attempt to speed up the anticancer drug discovery of indole-based Mcl-1 inhibitors.
