The copper(ii)-catalyzed and oxidant-promoted regioselective C-2 difluoromethylation of indoles and pyrroles

A novel and efficient approach for the highly selective C-2 difluoromethylation of indole derivatives was developed by using sodium difluoromethylsulfinate (HCF2SO2Na) as the source of difluoromethyl groups and a Cu(ii) complex as the catalyst. Various substrates were well tolerated in this transformation and the desired products were obtained in moderate to good yields. Moreover, the late-stage C-2 difluoromethylation of bioactive molecules containing an indole ring was achieved in good yields. Generally, this reaction features excellent functional group compatibility, broad substrate scope and excellent C-2 selectivity.

Computational design of an intramolecular photocyclization reaction with state-selective reactivity: a strategy for indole synthesis

The development of a convenient and environmentally friendly indole synthesis method is of great methodological and pharmaceutical interest. In this work, we discovered an intramolecular photocyclization of carbonyls and tertiary amines for indole synthesis without relying on photocatalysts. A wide range of functional indoles were prepared with moderate to excellent yields under mild reaction conditions. Furthermore, our extensive quantum mechanics (QM) calculations and synthesis experiments revealed the ‘state-selective reactivity’ feature of this reaction, and different substrate types can achieve different yields through this feature. This new insight into the interplay between the ‘state-selective reactivity’ and the yields emphasizes its importance and gives guidance regarding the ‘state-selective reactivity’ for the high yield of various indole derivatives.

Research progress of near-infrared fluorescence probes based on indole heptamethine cyanine dyes in vivo and in vitro

Near-infrared (NIR) fluorescence imaging is a noninvasive technique that provides numerous advantages for the real-time in vivo monitoring of biological information in living subjects without the use of ionizing radiation. Near-infrared fluorescent (NIRF) dyes are widely used as fluorescent imaging probes. These fluorescent dyes remarkably decrease the interference caused by the self-absorption of substances and autofluorescence, increase detection selectivity and sensitivity, and reduce damage to the human body. Thus, they are beneficial for bioassays. Indole heptamethine cyanine dyes are widely investigated in the field of near-infrared fluorescence imaging. They are mainly composed of indole heterocyclics, heptamethine chains, and N-substituent side chains. With indole heptamethine cyanine dyes as the parent, introducing reactive groups to the parent compounds or changing their structures can make fluorescent probes have different functions like labeling protein and tumor, detecting intracellular metal cations, which has become the hotspot in the field of fluorescence imaging of biological research. Therefore, this study reviewed the applications of indole heptamethine cyanine fluorescent probes to metal cation detection, pH, molecules, tumor imaging, and protein in vivo. The distribution, imaging results, and metabolism of the probes in vivo and in vitro were described. The biological application trends and existing problems of fluorescent probes were discussed.

Rhodium(III)-Catalyzed Regioselective Direct C4-Alkylation and C2-Annulation of Indoles: Straightforward Access to Indolopyridone

A straightforward Rh-III-catalyzed strategy was developed for the site-selective C4-alkylation and C2-annulation of indole by using electronically variable diazo esters. The transformation was accomplished with the assist of an oxime directing group at the C3 position of the indole core with wide scope and functional-group tolerance. The method directly provided an indolopyridone core. The selectivity was triggered by the reactivity of the diazo coupling partner.

Copper(II) and Nickel(II) complexes of the non-steroidal anti-inflammatory drug indomethacin containing aromatic chelating N,N-donor ligand: Synthesis and structural studies

Two complexes [Cu(indo)(2)(phen)(H2O)];Cu-1 and [Ni(indo)(2)(phen)(H2O)(2)]center dot 1.5H(2)O;Ni-1, were synthesized by the reaction of their respective metal(II)acetates with indomethacin (indo) [1-(4chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid)] and a nitrogen donor heterocyclic ligand 1,10-phenanthroline (phen) in acetonitrile: water mixture (9:1 v/v), by refluxing at 80 degrees C for 3 h. The complexes were characterized by physicochemical, spectroscopic, and TG analysis. X-ray structural analysis showed that both complexes crystallizes in the triclinic space group P-1. Cu-1 consists of Cu(II) in square pyramidal geometry and coordinated to two monodentate indomethacin ligands, a bidentate 1,10phenanthroline, and one aqua ligand. Intermolecular O-H center dot center dot center dot O, C-H center dot center dot center dot O, C-H center dot center dot center dot Cl, Cl center dot center dot center dot Cl, and C-H center dot center dot center dot interactions in Cu-1 were responsible for the stability of the complex. Ni-1 is centrosymmetric and consists of Ni(II) in a distorted octahedral geometry, involving two trans monodentate indomethacin ligands, a bidentate 1,10-phenanthroline ligand, and two cis aqua ligands. There were two lattice water molecules outside the coordination sphere of Ni-1, that participated in extensive O-H center dot center dot center dot O interactions. The complex was further stabilized by C-H center dot center dot center dot O, C-H center dot center dot center dot pi, and pi…pi interactions. The monodentate coordination of the carboxylato oxygen of indomethacin ligand in the complexes was confirmed from the FTIR studies. TG analysis provided information on the stability and decomposition pattern of the complexes. (C) 2020 Elsevier B.V. All rights reserved.

Recent Development in Indole Derivatives as Anticancer Agents for Breast Cancer

Background: Breast Cancer (BC) is the second most common cause of cancer related deaths in women. Due to severe side effects and multidrug resistance, current therapies like hormonal therapy, surgery, radiotherapy and chemotherapy become ineffective. Also, the existing drugs for BC treatment are associated with several drawbacks such as poor oral bioavailability, non-selectivity and poor pharmacodynamics properties. Therefore, there is an urgent need for the development of more effective and safer anti BC agents. Objective: This article explored in detail the possibilities of indole-based heterocyclic compounds as anticancer agents with breast cancer as their major target. Methods: Recent literature related to indole derivatives endowed with encouraging anti BC potential is reviewed. With special focus on BC, this review offers a detailed account of multiple mechanisms of action of various indole derivatives: aromatase inhibitor, tubulin inhibitor, microtubule inhibitor, targeting estrogen receptor, DNA-binding mechanism, induction of apoptosis, inhibition of PI3K/AkT/NFkB/mTOR, and HDAC inhibitors, by which these derivatives have shown promising anticancer potential. Results: Exhaustive literature survey indicated that indole derivatives are associated with properties of inducing apoptosis and disturbing tubulin assembly. Indoles are also associated with the inhibition of NFkB/mTOR/PI3K/AkT and regulation of estrogen-mediated activity. Furthermore, indole derivatives have been found to modulate critical targets such as topoisomerase and HDAC. These derivatives have shown significant activity against breast cancer cells. Conclusion: In BC, indole derivatives seem to be quite competent and act through various mechanisms that are well established in case of BC. This review has shown that indole derivatives can further be explored for the betterment of BC chemotherapy. A lot of potential is still hidden which demands to be discovered for upgrading BC chemotherapy.

Profiling of indole metabolic pathway in thermo-sensitive Bainong male sterile line in wheat (Triticum aestivum L.)

Bainong male sterile (BNS) wheat (Triticum aestivum L.) is a thermo-sensitive genic male sterile line with excellent sterility and self-restoration. We focused on transcriptional profiles of differentially expressed probes between BNS sterile and fertile anthers. Anthers, rachis and spikes from sterile line and fertile line were collected. Extracted RNA was assayed using wheat expression microarray and Gene Ontology was analyzed using Cytoscape with ClueGO. An indole (indole-3-acetic acid: IAA) metabolism pathway sub-network was almost formed in all differentially expressed profiles between sterile and fertile samples. IAA sub-network contained four nodes of indole and alkaloid metabolism connecting main network via indole compounds. This sub-network was absent in rachis and intact in transformed fertile anthers, which was the main differently expressed metabolism pathway in F-1 anthers with restorer genes. Alkaloid metabolism was absent in sterile anthers. Abnormal metabolism of IAA may be involved in BNS sterility. BNS transformation may be regulated by the production of IAA and alkaloid metabolism pathway, which favor the safe utilization of the sterile line in hybrid wheat production.

Isonitrile-Derivatized Indole as an Infrared Probe for Hydrogen-Bonding Environments

The isonitrile (NC) group has been shown to be a promising infrared probe for studying the structure and dynamics of biomolecules. However, there have been no systematic studies performed on the NC group as an infrared probe, when it is bonded to an indole ring. Here, we systematically study the NC stretching mode of two model compounds, 5-isocyano-1H-indole (5ICI) and 5-isocyano-1-methyl-1H-indole (NM5ICI), using Fourier transform infrared (FTIR) spectroscopy. The NC stretching frequency is shown to be strongly dependent on the polarizability of protic solvents and the density of hydrogen-bond donor groups in the solvent when NC is bonded to an indole ring. Infrared pump-probe studies of 5ICI in DMSO and in EtOH further support that the NC stretching mode could be used as a site-specific infrared probe for local environments when NC is bonded to an indole ring.
