Access to Polycyclic Azepino[5,4,3-cd]indoles via a Gold-Catalyzed Post-Ugi Dearomatization Cascade

The development of a rapid and diverse access to complex natural product-like 3,4-fused indole scaffolds has always attracted considerable attention from synthetic and medicinal communities. We herein disclose a modular and straightforward protocol to prepare the densely substituted polycyclic azepino-[5,4,3-cd]indole scaffolds. This synthetic process involves an Ugi four-component reaction from easily available starting materials and a gold-catalyzed post-Ugi domino dearomatization/Michael addition sequence, enabling facile access to the highly functionalized azepino[5,4,3-cd]indole core with excellent chemo-, regio-, and diastereoselectivity.

Transcriptome-wide identification, characterization, and phylogenomic analysis of cytochrome P450s from Nothapodytes nimmoniana reveal candidate genes involved in the camptothecin biosynthetic pathway

The plant Nothapodytes nimmoniana is an important source of camptothecin (CPT), an anticancer compound widely used in the treatment of colorectal, lung, and ovarian cancers. CPT is biosynthesized by the combination of the seco-iridoid and indole pathways in plants. The majority of the biosynthetic steps and associated genes still remain unknown. Certain reactions in the seco-iridoid pathway are catalyzed by cytochrome P450 enzymes. Hence, identifying transcriptionally active cytochrome P450 genes becomes essential in the elucidation of the CPT biosynthetic pathway. Here, we report the identification of 94 cytochrome P450s from the assembled transcriptomic data from leaf and root tissues of N. nimmoniana. The identified cytochrome P450 genes were full length and possessed all four conserved characteristic signature motifs of cytochrome P450 genes. Phylogenetic analysis of the protein sequences revealed their evolution and diversification and further categorized them into A-type (52.12%) and non-A-type (47.87%) cytochrome P450s. These 94 sequences represent 38 families and 63 subfamilies of cytochrome P450s. We also compared the transcriptional activity of identified cytochrome P450s with the expression of their homologs in the CPT-producing plant Ophiorrhiza pumila. Based on expression profiles and quantitative PCR validation, we propose NnCYP81CB1 and NnCYP89R1 as candidate cytochrome P450 genes involved in camptothecin biosynthesis in N. nimmoniana.

Synthesis and evaluation of 2-carboxy indole derivatives as potent and selective anti-leukemic agents

Despite the success achieved in the treatment of acute lymphoblastic leukemia (ALL), the search for new drugs featuring selectivity against leukemia cells and effectiveness to prevent relapsed ALL is still highly desirable. Here, we described the synthesis of several novel 3-substituted and 3,6-disubstituted-2-carboalkoxy indoles followed by the elucidation of their mechanism of action and in vivo anti-leukemia efficacy. The synthesis of 3-substituted-2-carboalkoxy indoles relied on two Heck arylations of methyl acrylate and methyl cinnamates respectively, to generate beta,beta-disubstituted acrylates followed by an efficient Cadogan-Sundberg reaction of these latter intermediates. The method developed led to the synthesis of twenty-one novel functionalized indoles. Of these, indole 20 showed selective cytotoxicity against leukemia cells at the nanomolar scale, and, therefore, it was selected for the investigation of its mechanism of action. Indole 20 was found to target tubulin leading to G2/M cell cycle arrest, DNA damage and apoptosis. Indole 20 decreased beta-tubulin protein in leukemia cells in a time-dependent manner and induced depolymerization of the microtubule network in Hela cells, thus fully characterizing its microtubule destabilizer activity. The connectivity map analysis of HL60 promyelocytic leukemia cells treated with indole 20 revealed a transcriptional profile similar to that of cells treated with prostaglandins, apparently due to the induction of cellular differentiation as addressed by the expression of CD11 and CD14 markers. Finally, indole 20 given intraperitoneally, at 10 mg/kg, 5x/week significantly prolonged the overall survival of NOD/SCID mice transplanted with RS4; 11 B-ALL cells. (C) 2019 Elsevier Masson SAS.

Synthesis, spectroscopic, computational and drug docking studies of 1-(benzenesulfonyl)-2-methyl-1H-indole-3-carbaldehyde

An N-Substituted 1H-indole derivative having an empirical formula C16H13NO3S was synthesized by the condensation of 2-Methyl-1H-Indole-3-carbaldehyde and benzene sulfonyl chloride in presence of a phase transfer catalyst of type quaternary ammonium salt in basic conditions. Then the compound was characterized by using FT-IR, UV-Visible and NMR spectroscopic methods. Thus the obtained experimental results were effectively compared with DFT studies in arriving the structural characteristics of the title compound. From vibrational analysis, it was observed that carbonyl frequency is somewhat lower than a typical aldehydic stretching frequency and it could be possible only when the formyl group is coplanar with the ring and subsequent resonance conjugation reduces its force constant. Similarly, the optical absorption behavior of a typical indole ring suffered from a bathochromic shift due to the presence of ring substituents. Finally, the molecular drug docking studies of the title compound were performed using AutoDock 4.2 tools to ascertain its binding mode, efficiency and the nature of chemical interactions with the target proteins and it has been predicted theoretically that the binding efficiency of the ligand on the target receptor surface was found to be better in the case of Gram positive bacteria S. Aureus than the Gram negative N. Meningitidis. (C) 2018 Published by Elsevier B.V.

Performance and microbial community analysis of bioaugmented activated sludge for nitrogen-containing organic pollutants removal

Nitrogen-containing organic pollutants (quinoline, pyridine and indole) are widely distributed in coking wastewater, and bioaugmentation with specific microorganisms may enhance the removal of these recalcitrant pollutants. The bioaugmented system (group B) was constructed through inoculation of two aromatics-degrading bacteria, Comamonas sp. Z1 (quinoline degrader) and Acinetobacter sp. JW (indole degrader), into the activated sludge for treatment of quinoline, indole and pyridine, and the non-bioaugmented activated sludge was used as the control (group C). Both groups maintained high efficiencies (> 94%) for removal of nitrogen-containing organic pollutants and chemical oxygen demand (COD) during the long-term operation, and group B was highly effective at the starting period and the operation stage fed with raw wastewater. High-throughput sequencing analysis indicated that nitrogen-containing organic pollutants could shape the microbial community structure, and communities of bioaugmented group B were clearly separated from those of non-bioaugmented group C as observed in non-metric multidimensional scaling (NMDS) plot. Although the inoculants did not remain their dominance in group B, bioaugmentation could induce the formation of effective microbial community, and the indigenous microbes might play the key role in removal of nitrogen-containing organic pollutants, including Dokdonella, Comamonas and Pseudoxanthomonas. Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) analysis suggested that bioaugmentation could facilitate the enrichment of functional genes related to xenobiotics biodegradation and metabolism, probably leading to the improved performance in group B. This study indicated that bioaugmentation could promote the removal of nitrogen-containing organic pollutants, which should be an effective strategy for wastewater treatment.
