Abstract
In this research, the functionalized silica-coated magnetite nanoparticles with Cu(i)-thiosemicarbazone complex (Fe3O4@SiO2-[CuL]) has been designed and synthesized as a magnetically retrievable nanocatalyst. Different techniques were employed to characterize the structure of Fe3O4@SiO2-[CuL] comprising FT-IR, FE-SEM, TEM, DLS, XRD, EDX, TGA, AAS, and VSM analysis. The catalytic performance of Fe3O4@SiO2-[CuL] was perused in Ullmann-type N-arylation of nucleobases, xanthines, and other N-heterocycles with diverse aryl halides which acquired the desired N-aryl products in good to excellent yields. Fe3O4@SiO2-[CuL] is a thermal and chemical stable, easy to prepare and recyclable, inexpensive, and ecofriendly catalyst that needs no additional additive or ligand as promoters. This catalyst could be separated without difficulty by a simple magnet and reused for at least seven sequential runs without a significant decline in its catalytic performance.

Abstract
A tricatalytic telescoped synthesis toward C3-methyl-N-aryl indoline and indole products is reported. An in situ generated tantalum(V) ureate catalyst is used for the hydroaminoalkylation of o-chlorostyrene with N-methylaniline to first make a Csp3─Csp3 bond. Subsequent nickel-catalyzed C-N coupling forms N-aryl indolines, and if desired, subsequent oxidation to N-aryl indoles can be achieved using catalytic [Cu(MeCN)4]BF4 and tert-butylperoxy-2-ethylhexyl carbonate as the terminal oxidant. This strategy highlights an alternative C-C bond disconnection for the synthesis of indoles, which is enabled by the atom-economic hydroaminoalkylation reaction. The method was streamlined using a three-step, two-pot approach to afford up to 73% overall isolated yield of variously substituted C3-methyl-N-aryl indoles.

Abstract
A simple, efficient, and cheap strategy has been developed for N-arylation of
indoles with hexafloro benzene (1) via incorporating sulfolane as an eco-friendly solvent. N-Monopentafluoroarylindole
(3) at ambient conditions and N, N-bistetrafluoroaryl indole (4)
at elevated temperatures were conveniently obtained by simple nucleophilic substitution
using NaOH as the base and sulfolane as a reaction medium to obtain in moderately good
yields, respectively. Subsequently, 3-chloro, 3-bromo, and 3-iodomono-pentafluoroarylindoles
and 3, 3’-dichloro, 3, 3’-dibromo and 3, 3’-diIodobistetrafluoroaryl indoles were
prepared in good yields by using respective halogenating reagents and solvents. All the
chemical transformations were confirmed by analytical tools such as 1HNMR, FR-IR and
HRMS analysis.

Abstract
Antimicrobial resistance is widely recognized as a grave threat to global health in the 21st century, since the past decades have seen a dramatic increase in human-pathogenic bacteria that are resistant to one or multiple antibiotics. New antimicrobial agents are urgently required, particularly in the treatment of chronic infections such as cystic fibrosis, often associated with persistent colonization by drug-resistant pathogens and epithelial damage by pulmonary oxidative stress. In such events, it would be favourable to find agents that could have antioxidant and antibacterial activities combined in one molecule. The discovery of compounds that can show a dual-target activity considerably increased in the last years, reflecting the growing confidence that this new approach could lead to better therapeutic solutions for complex multigenic diseases. The aim of this review is to report those natural and synthetic compounds displaying significant antioxidant and antibacterial activities. In recent years there has been a growing attention on plant-derived antimicrobials as an alternative to antibiotics, for their efficacy and low tendency in developing bacterial resistance. Moreover, it was found that some natural products could enhance the activity of common antibiotics displaying a synergistic effect. We then report some selected synthetic compounds with an in-built capacity to act on two targets or with the combination in a single structure of two pharmacophores with antioxidant and antibacterial activities. Recent literature instances were screened and the most promising examples of dual-active antibacterial-antioxidant molecules were highlighted.

Abstract
Seven novel N-arylsulfonyl-3-(2-yl-ethanone)-6-methylindole derivatives 4a-f and 6 were readily synthesized and have been identified as inhibitors of human immunodeficiency virus type-1 (HIV-1) replication. Initial biological studies indicated that among these derivatives, N-(p-ethyl)phenylsulfonyl-3-[2-morpholinoethanone]-6-methylindole (4f) and N-(p-ethyl)phenylsulfonyl-3-[2-(5-phenyl-1,3,4-oxadiazole-2-yl-thio)ethanone]-6-methylindole (6) showed the most promising activity against HIV-1 replication. The effective concentration (EC50) and therapeutic index (TI) values of 4f and 6 were 9.42/4.62 μM, and >49.77/66.95, respectively. The cytotoxicity of these compounds has also been assessed. No significant cytotoxicities were found for any of these compounds.

Abstract
Indole represents one of the most important privileged scaffolds in drug discovery. Indole derivatives have the unique property of mimicking the structure of peptides and to bind reversibly to enzymes, which provide tremendous opportunities to discover novel drugs with different modes of action. There are seven indole-containing commercial drugs in the Top-200 Best Selling Drugs by US Retail Sales in 2012. There are also an amazing number of approved indole-containing drugs in the market as well as compounds currently going through different clinical phases or registration statuses. This review focused on the recent development of indole derivatives as antiviral agents with the following objectives: 1) To present one of the most comprehensive listings of indole antiviral agents, drugs on market or compounds in clinical trials; 2) To focus on recent developments of indole compounds (including natural products) and their antiviral activities, summarize the structure property, hoping to inspire new and even more creative approaches; 3) To offer perspectives on how indole scaffolds as a privileged structure might be exploited in the future.

Abstract
An efficient one-pot step by step t-BuOK-mediated procedure for the synthesis of N-arylindoles has been developed in moderate to good yields. The protocol involves the consecutive deprotection of N-arylsulfonylindoles as latent indoles and subsequent S(N)Ar reactions with activated aryl halides. This tandem reaction affords an efficient and convenient preparation of N-arylindoles that benefit from prior indoles protection by arylsulfonyl group, and can shorten a reaction sequence and improve synthetic efficiency.
