Aromatic Aza-Claisen Rearrangement of Arylpropargylammonium Salts Generated in situ from Arynes and Tertiary Propargylamines

The charge-accelerated aza-Claisen rearrangement of ammonium salts serves as a key step in the construction of complex nitrogen-containing molecules. However, much less attention has been paid to the aromatic aza-Claisen rearrangement than to the aliphatic one. Herein, we report an unprecedented aromatic aza-Claisen rearrangement of arylpropargylammonium salts, generated in situ from arynes and tertiary propargylamines, delivering structurally diverse 2-propargylanilines in moderate to good yields with high regioselectivity. This rearrangement proceeds in the absence of strong bases or transition metals, is compatible with moisture and air, tolerates a wide variety of functional groups, and is amenable to forming 11- to 13-membered heterocycles with a triple bond. The 2-propargylaniline products were treated with aluminum chloride in ethanol to afford multisubstituted indoles in moderate to excellent yields. Finally, a series of deuterium-labeling experiments was performed to elucidate the reaction mechanism.

Indoles – Gut Bacteria Metabolites of Tryptophan with Pharmacotherapeutic Potential

Background: Increasing evidence proves the pivotal role of gut microbiota in mammals’ homeostasis. Gut bacterial metabolites may exert local effects on the intestines, and may enter the circulation, affecting the functions of virtually all organs. Here, we review the available evidence on metabolism and biological effects of gut microbiota-derived indoles. Method: The PUBMED database and Google Scholar were searched to identify experimental and clinical studies investigating biological effects of gut bacteria-derived indoles. Key words included: gut microbiota, indoles, indole and tryptophan. Results: Indoles represent a wide group of gut bacteria-derived compounds produced from tryptophan, an essential amino acid and the precursor of endogenous synthesis of tryptamine, serotonin and melatonin. Ample evidence suggests that indoles derived from gut microbiota metabolism exert significant biological effects and may contribute to the etiology of cardiovascular, metabolic, and psychiatric diseases. However, a majority of the research is limited to experimental studies and only a small number of clinical trials. Conclusion: Bacterial indoles affect the function of many biological systems. Whether gut-derived indoles contribute to pathogenesis of cardiovascular, metabolic and other diseases, requires further clinical studies.

pH-Dependent Protein Binding Properties of Uremic Toxins In Vitro

Protein-bound uremic toxins (PBUTs) are difficult to remove using conventional dialysis treatment owing to their high protein-binding affinity. As pH changes the conformation of proteins, it may be associated with the binding of uremic toxins. Albumin conformation at pH 2 to 13 was analyzed using circular dichroism. The protein binding behavior between indoxyl sulfate (IS) and albumin was examined using isothermal titration calorimetry. Albumin with IS, and serum with IS, p-cresyl sulfate, indole acetic acid or phenyl sulfate, as well as serum from hemodialysis patients, were adjusted pH of 3 to 11, and the concentration of the free PBUTs was measured using mass spectrometry. Albumin was unfolded at pH < 4 or >12, and weakened interaction with IS occurred at pH < 5 or >10. The concentration of free IS in the albumin solution was increased at pH 4.0 and pH 11.0. Addition of human serum to each toxin resulted in increased free forms at acidic and alkaline pH. The pH values of serums from patients undergoing hemodialysis adjusted to 3.4 and 11.3 resulted in increased concentrations of the free forms of PBUTs. In conclusion, acidic and alkaline pH conditions changed the albumin conformation and weakened the protein binding property of PBUTs in vitro.

Synthesis, Antimicrobial Activity, Structure-Activity Relationship, and Molecular Docking Studies of Indole Diketopiperazine Alkaloids

Strategies for the synthesis of indole diketopiperazine alkaloids (indole DKPs) have been described and involve three analogs of indole DKPs. The antimicrobial activity and structure-activity relationship (SAR) of 24 indole DKPs were explored. Compounds 3b and 3c were found to be the most active, with minimum inhibitory concentrations (MIC) values in the range of 0.94-3.87 mu M (0.39-1.56 mu g/mL) against the four tested bacteria (Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli). Furthermore, compounds 4a and 4b displayed broad-spectrum antimicrobial activity with MIC values of 1.10-36.9 mu M (0.39-12.5 mu g/mL) against all tested bacteria and plant pathogenic fungi (Colletotrichum gloeosporioides, Valsa mali, Alternaria alternata and Alternaria brassicae). According to the in silico study, compounds 3c showed significant binding affinity to the FabH protein from Escherichia coli, which has been identified as the key target enzyme of fatty acid synthesis (FAS) in bacteria. Therefore, these compounds are not only promising new antibacterial agents but also potential FabH inhibitors.

Competitive adsorption between sulfur- and nitrogen-containing compounds over NiMoS nanocluster: The correlations of electronegativity, morphology and molecular orbital with adsorption strength

Using combination of density functional theory calculation and dispersion corrections, we try to find the correlation between nature of nitrogen-containing compounds (indole, quinoline, carbazole and acridine) as well as their hydrodenitrogenation intermediates and the adsorption strength of them over multisite NiMoS nanocluster, and to utilize the correlation into the competitive adsorption between N-compounds and S-compounds. The competitiveness of aromatic compounds and HDT by-products are included. The results show the adsorption strength is not only dominant by the electronegativity but also influenced by the morphology of N-compounds and the lowest-unoccupied molecular orbitals of active sites. For multisite NiMoS, the influence of competitive adsorption decreases as Corner approximate to Mo-Edge > S-Edge; for certain N-compound series, almost all the adsorption strength is larger than that of corresponding S-compound. Except for the N-compounds themselves, the potential strong inhibitors should be the partial or fully saturated intermediates as well as ammonia. (C) 2020 Elsevier Ltd. All rights reserved.

CRISPR/Cas9 genome editing in ergot fungus Claviceps purpurea

Claviceps purpurea is a filamentous fungus well known as a widespread plant pathogen, but it is also an important ergot alkaloid producer exploited by the pharmaceutic industry. In this work, we demonstrated that CRISPR/Cas9 can be a tool for directed mutagenesis in C. purpurea targeting pyr4 and TrpE genes encoding the orotidine 5′-phosphate decarboxylase involved in pyrimidine biosynthesis and the a-subunit of the anthranilate synthase involved in tryptophan biosynthesis, respectively. After protoplast transformation and single spore isolation, homokaryotic mutants showing uridine or tryptophan auxotrophy were selected. In all cases, insertions or insertions combined with deletions were found mostly 3 bp upstream of the PAM sequence. However, transformation efficiencies of CRISPR/Cas9 and CRISPR/Cas9 mediated homology-directed repair only slightly improved in comparison to homologous recombination-mediated knocking-out of the TrpE gene. Moreover, Trp auxotrophs were non-infectious towards rye plants likely due to a decreased production of the plant hormones auxins, which are synthesized by C. purpurea from indole-3-glycerolphosphate in Trp-dependent and Trp-independent biosynthetic pathways, and help the fungus to colonize the plant host. It was demonstrated that the CRISPR/Cas9 vector containing autonomous replicative sequence AMA1 can be fully removed by further culturing of C. purpurea on non-selective media. This method enables introducing multiple mutations in Claviceps and makes feasible metabolic engineering of industrial strains.

Enhanced in vitro shoot proliferation through nodal explants of Staurogyne repens (Nees) Kuntze

In this study, multiple and rapid propagations of Staurogyne repens (Nees) Kuntze with tissue culture techniques were aimed. The nodal explants of S. repens were cultured for multiple shoot regeneration in culture medium supplemented with different rates of 6-Benzilaminopurin (BAP) and Kinetin (KIN) alone (0.25-1.50 mg/L) or combinations with 0.25 mg/L Indole-3-acetic acid (IAA). Generally, shoot regeneration capabilities of the explants were high due to the growth regulators used. Shoot regeneration frequencies were ranked between 77.77% and 100.00% in BAP-IAA and KIN-IAA applications. In BAP-IAA application, the average number of shoots was recorded between 2.53-16.11 shoots/explant and the highest number of shoots per explant (16.11 shoots/explant) was obtained in culture medium containing 1.25 mg/L BAP. As the BAP level used increased, the number of regenerated shoots increased. In KIN-IAA application, mean shoot counts were recorded as 2.66-10.27 shoots/explant, and maximum shoots per explant (10.27 shoots/explant) was determined in culture medium containing 0.50 mg/L KIN. When shoot lengths were examined, longer shoots were seen in KIN-IAA application compared to BAP-IAA application. The longest shoot was obtained as 2.82 cm in the culture medium fortified with 1.50 mg/L KIN. Regenerated shoots for in vitro rooting were transferred to the growth culture containing different concentrations of IAA and 1-Naphthaleneacetic acid (NAA). The best values in terms of number and length of roots per shoot were determined in a growth culture containing 0.25 mg/L IAA. The rooted shoots were accustomed to external conditions successfully.
