In this personal account, our recent studies of novel synthetic methods of 3,4-fused tricyclic indole derivatives using 3-alkylidene indoline derivatives as versatile precursors are discussed. Two types of cascade reactions producing 3,4-fused tricyclic 3-alkylidene indolines were developed based on a palladium-catalyzed intramolecular Heck insertion to an allene-allylic amination cascade and a platinum-catalyzed intramolecular Friedel-Crafts type C-H coupling-allylic amination cascade. Furthermore, three types of 3,4-fused tricyclic indoles were accessible from a single 3-alkylidene indoline precursor via acid-promoted olefin isomerization or oxidative treatments. The application of the developed methods to the synthesis of natural products bearing a 3,4-fused tricyclic indole skeleton, (-)-aurantioclavine, fargesine, and synthetic studies of dragmacidin E are also highlighted.

Interest in indolic structure metabolites, including a number of products of microbial biotransformation of the aromatic amino acid tryptophan, is increasingly growing. The review prepared by a team of authors is based on in-depthscrutiny of data available in PubMed, Scopus, Cyberleninka, Clinical Trials, and Cochrane Library, eventually narrowing the search to a set of keywords such as tryptophan metabolites; plasma metabolomics profiling; metabolomics fingerprinting; gas-, liquid chromatography mass spectrometry; serotonin; melatonin; tryptamine; indoxyl sulfate: indole-3-acetic acid; indole-3-propionic acid; 5-hydroxyindole-3-acetic acid; gut microbiota and microbial metabolites. it provides a summary that outlines the pattern of changes in the level of indolic structure metabolites in a number of diseases and deals with the data from the field of human microbiota metabolites. In modern experimental studies, including the use of gnotobiological (germ-free) animals, it has been convincingly proved that the formation of tryptophan metabolites such as indole-3-acetic acid, indole-3-propionic acid, tryptamine, and indoxyl sulfate is associated with gut bacteria. Attention to some concentration changes of indolic compounds is due to the fact that pronounced deviations and a significant decrease of these metabolites in the blood were found in a number of serious cardiovascular, brain or gastrointestinal diseases. The literature-based analysis allowed the authors to conclude that a constant (normal) level of the main metabolites of the indolic structure in the human body is maintained by a few strict anaerobic bacteria from the gut of a healthy body belonging to the species of Clostridium, Bacteroides, Peptostreptococcus, Eubacteria, etc. The authors focus on several metabolites of the indolic structure that can be called clinically significant in certain diseases, such as schizophrenia, depression, atherosclerosis, colorectal cancer, etc. Determining the level of in-dole metabolites in the blood can be used to diagnose and monitor the effectiveness of a comprehensive treatment approach.

Leptadenia reticulata (Retz.) Wight and Arn is an important medicinal plant of Asclepiadaceae family. In the present study regeneration was attempted using leaf and nodal explants in Murashige and Skoog’s (MS) medium fortified with sucrose (3%) and different cytokinins like 6-benzyladenine (BA), kinetin (Kn) and adenine sulphate (AdSO(4)) in 5-20 mu M concentration range and auxins like indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D) in 0.1-1.0 mu M concentration range. Through leaf explants total 21.70 +/- 2.06 somatic embryos were recorded in 100% cultures in BA (15 mu M) with AdSO(4) (15 mu M). Further these embryos were transferred to static medium augmented with gibberellic acid (GA(3), 1 mu M) facilitated development of plantlets within 8 weeks. Inoculating nodal explants in BA (10 mu M) with AdSO(4) (10 mu M) formed total 5.10 +/- 0.33 shoots (100% response). Callus and shoot cultures derived through leaf and nodal explants respectively were further qualitatively and quantitatively analyzed for their biosynthetic potential. High-performance thin layer chromatography (HPTLC) fingerprints of the samples confirmed that the in vitro shoots showed almost similar banding patterns in comparison with in vivo shoots in terms of number of peaks and band on TLC plate, whereas in callus samples the banding pattern was differed. Further quantification of p-coumaric acid revealed that in in vivo and in vitro shoots it was in LOD (10 mu g) range but out of LOQ (100 mu g). Whereas it was quantified 78.08 +/- 2.20 mg g(-1) of dry weight (DW) in 6 weeks old callus cultures obtained from BA (20 mu M) + NAA (0.5 mu M) fortified medium, which indicate that it can become a chemical marker for L. reticulata. This protocol can be utilized for true-to-type plant regeneration as well as conservation of this threatened medicinal plant. Chemical fingerprint can be utilized for authentication of L. reticulata and callus cultures as an alternative source to wild plants for production of p-coumaric acid. Key message SEs were efficiently developed in L. reticulata. In vitro cultures were able to synthesize metabolites but callus is prominent source for p-coumaric acid. Hence it can be alternative to wild plants.

Neisseria meningtidis is responsible for causing meningococcal meningitis along with acute septicaemia in human beings. Functional genomics strategies proved cruciality of certain genes/proteins in Neisseria meningitidis pathogenesis. During the present studies, three important Neisseria meningitidis proteins i.e., Dead box RNA-Helicase, Polyribonucleotide nucleotidyl-transferase PNPase and Ribonuclease-III were targeted for homology modeling and protein-ligand docking studies not only to detelinine their three dimensional architectures but also to identify their potential novel inhibitors. The Biscoumarin, malonitrile and indole derivatives showed the best inhibitory mode against all of the three enzymes. Since, these enzymes are assembled in Gram-negative bacteria to foul’ RNA degradosome assembly therefore their inhibition will definitely shut off the degradosome assembly and ultimately the decay of RNA, which is an essential life process. This is the first ever structural investigation of these drug targets along with identification of potential novel drug candidates. We believe that these small chemical compounds will be proved as better drugs and will provide an excellent barrier towards Neisseria meningitidis pathogenesis.

This paper is a continuation of lipophilicity research on 14 compounds (tryptophan, kynurenine pathway products, auxin pathway products, serotonin pathway products, tryptamine, as well as two synthetic auxin analogs): indole-2-acetic acid sodium salt (IAA), serotonin, 5-hydroxy-L-tryptophan, tryptamine, L-tryptophan, L-kynurenine (KYN), kynurenic acid (KYA), 3-hydroxy-DL-kynurenine, naphtyl-1-acetamide, indole-3-propionic acid (IPA), naphthalene-1-acetic acid (NAA), indole-3-butyric acid (IBA), indole-3-pyruvic acid (IPV), as well as melatonin. They were chromatographed in high performance liquid chromatography gradient conditions on tree stationary phases (C18, CN, DIOL) using three modifiers on each phase (methanol, acetonitrile and acetone). The resulting retention data was correlated with computational lipophilicity indices. Six compounds were proven to be ionized in neutral pH physiological conditions (IAA, KYA, IPA, NAA, IBA and IPV) and they were rechromatographed with acidic mobile phase to enhance the resulting dataset. It can be concluded that the retention times are highly correlated with lipophilicity regardless of used modifier and column and the main differentiating trend can be only connected to presence of naphthalene or indole ring. The principal component analysis, additive linear modeling, as well as multiplicative trilinear parallel factor analysis (PARAFAC) modeling helped to understand the internal structure of the obtained results.

Background: Phase transfer catalysis technique is recognized as an attractive method for synthesizing several organic compounds under heterogeneous reaction. Methods: In this study, the effect of Multi-site Phase-Transfer Catalyst (MPTC) was tested during the synthesis of 1-(4-nitrophenyl)-1-indole from 1-chloro-4-nitrobenzene (CNB) and indole in a heterogeneous solid-liquid condition using sodium hydroxide at 50 degrees C. Results: In a synergetic condition, in the presence of MPTC the conversion of 1-chloro-4-nitrobenzeneyield was increased, which is proved the efficacy of this catalyst. In addition, the rate of this reaction was also enhanced by the change in volume of water. Conclusion: The apparent reaction rate was found to be of pseudo-first-order kinetics. MPTC is a promising tool for many organic reactions. Therefore, increase the rate constant can be achieved by various parameters, such as temperature, MPTC, sodium hydroxide, and stirring speed.

The intramolecular electrophilic cyclization of 3-organoselanyl-2-alkynylindoles providing the synthesis of 3-iodo-selenophene-fused indoles is reported herein. The strategy was extended to the preparation of 3-iodo-thiophene-fused indoles in a one-pot iodine-promoted thiolation of 2-alkynylindoles, followed by an electrophilic cyclization sequence. Besides, the synthesis of 3-butylselanyl-selenophene-fused indoles from 3-butylselanyl-2-alkynylindoles was also developed using iron(III) chloride and dibutyl diselenide to promote the cyclization and functionalization of the heterocycle. The identification of the alkyl halide intermediate afforded evidence to the proposed mechanism, which indicated that the reactions proceed through the formation of an iodonium ion, followed by a selenium 5-endo-dig cyclization, to afford the indole derivatives. The 3-iodo-selenonophene-fused indoles prepared were applied as substrates in copper-catalyzed cross-coupling reactions with thiols to give the Ullmann type products in good yields.
