Extensive data have reported the involvement of oxidative stress in the pathogenesis of neuropsychiatric disorders, prompting the pursuit of antioxidant molecules that could become adjuvant pharmacological agents for the management of oxidative stress-associated disorders. The 3-[(4-chlorophenyl)selanyl]-1-methyl-1H-indole (CMI) has been reported as an antioxidant and immunomodulatory compound that improves depression-like behavior and cognitive impairment in mice. However, the exact effect of CMI on specific brain cells is yet to be studied. In this context, the present study aimed to evaluate the antioxidant activity of CMI in H2O2-induced oxidative stress on human dopaminergic neuroblastoma cells (SH-SY5Y) and to shed some light into its possible mechanism of action. Our results demonstrated that the treatment of SH-SY5Y cells with 4 mu M CMI protected them against H2O2 (343 mu M)-induced oxidative stress. Specifically, CMI prevented the increased number of reactive oxygen species (ROS)-positive cells induced by H2O2 exposure. Furthermore, CMI treatment increased the levels of reduced glutathione in SH-SY5Y cells. Molecular docking studies demonstrated that CMI might interact with enzymes involved in glutathione metabolism (i.e., glutathione peroxidase and glutathione reductase) and H2O2 scavenging (i.e., catalase). In silico pharmacokinetics analysis predicted that CMI might be well absorbed, metabolized, and excreted, and able to cross the blood-brain barrier. Also, CMI was not considered toxic overall. Taken together, our results suggest that CMI protects dopaminergic neurons from H2O2-induced stress by lowering ROS levels and boosting the glutathione system. These results will facilitate the clinical application of CMI to treat nervous system diseases associated with oxidative stress. [GRAPHICS] .

The Summary of main observation and conclusion A Rh-III/Ag-I relay-catalyzed C(sp(2))-H coupling of indoles with triarylhexahydrotriazine (THT) is reported in this context. Upon merging Rh-III-catalyzed C(sp(2))-H bond activation and silver promoted THT dissociation, an efficient indole’s C3 aminomethylation protocol is uncovered, providing C3 aminomethyl indoles in good yields and exhibiting potential applications for the synthesis of complicated bioactive compounds. We revealed the C3-selectivity of this reaction through a detailed mechanistic investigation. Meanwhile, during the examination of the reaction conditions, we discovered another [4+2] cycloaddition pathway to afford tetrahydro-indolo[3,2-c]quinoline scaffold products via silver or Lewis acid catalysis.

Ethnopharmacological relevance: The leaf of Sarcocephalus latifolius is known to be used traditionally by the Fulanis in Nigeria to deworm animals. As helminthosis remains a major constraint to profitable livestock production worldwide, a precarious situation aggravated by the advent of resistant parasites, the discovery of new anthelmintics is a priority, necessitating exploration of medicinal plants for their anthelmintic principles. Aim of the study: To identify and characterise compounds with anthelmintic activity from the leaf of Sarcocephalus latifolius. Materials and methods: Powdered S. latifolius leaves were extracted by successive maceration with n-hexane, chloroform and acetone. The dried extracts were evaluated for anthelmintic activity against Haemonchus placei adult worms, and the most active extract was subjected to bioassay-guided chromatographic separations. The isolated compounds were evaluated for cytotoxicity against the mammalian HeLa and MC3T3-E1 cell lines, using alamar blue and CellTitreGlo (TM) to quantify cell viability. LC50 values were computed from the in vitro anthelmintic activity data by fitting to a non-linear regression equation (variable slope). Isolated compounds were characterized using spectroscopic and mass spectrometric analyses. Results: Anthelmintic activity LC50 values for n-hexane, chloroform and acetone extracts were 47.85, 35.76 and 5.72 (mg/mL), respectively. Chromatographic separation of acetone extract afforded two bioactive epimers, identified as vincosamide (LC50 14.7 mg/mL) and strictosamide (LC50 12.8 mg/mL). Cytotoxicity evaluation showed that, below 200 mu g/mL (400 mu M), neither compound was toxic to the HeLa or MC3T3-E1 cells. Conclusion: Vincosamide and strictosamide could serve as novel scaffolds for the development of anthelmintic derivatives with improved potency and helminth selectivity.

A novel palladium(0)-catalyzed intermolecular coupling reaction of 2-gem-dibromovinylanilines and N-tosylhydrazones was reported to construct 2-(1-phenylvinyl)-indoles efficiently. The indole bearing 1, 1-disubstituted alkenes were obtained in one step with short reaction time, in high yields and broad substrate scope. The formed indole derivates could be easily transformed into much more valuable molecules.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.

Tissue culture has been widely used for the propagation of papaya (Carica papaya L.). Generally, agar-based media supplemented with the appropriate amount of indole-3-butyric acid (IBA) is used for the in-vitro rooting and root elongation of the papaya explants. However, it is usually resulted in a difficulty in adventitious root (AR) formation and turns into callus formation. The AR formation was influenced by miscellaneous factors, however little is known of the related regulative mechanisms. In this study, RNA-seq was performed on samples collected from leaf-inoculation (LI) and stem-inoculation (SI) GZY6 shoot explants to reveal their different rooting phenotypes. Here, we found that the ARs were induced from in GZY6 (79.17%), GZG4 (63.33%), and GZM26 (37.23%) hermaphroditic papaya shoot explants obtained by LI method after 2 weeks of culture in root-induction medium, but calli were formed rather than AR from the explants obtained by SI method in root-induction medium. The SI and LI shoot explant samples of GZY6 genotypes (the rooting percentage was highest in the three genotypes) were used for the transcriptomic analyses. A total of 2498 differentially expressed genes (DEGs) were identified in the LI vs. SI samples and annotated into 73 Gene ontology (GO) terms. The GO analysis revealed that oxidative-stress, defense-response, and stimulus-response GO terms were significantly different between the LI and SI shoot explants and that the genes are involved in anaerobic respiration and reactive oxygen species (ROS) metabolism pathways. Twelve selected anaerobic and ROS metabolic pathways-related DEGs were used to validate the RNA-seq data by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The activity of superoxide dismutase (SOD) and peroxidase (POD) and the concentration of hydrogen peroxide (H2O2) increased in the SI explants. ARs formation and development were significantly higher in the SI explants in perlite medium than in agar medium, when both were not supplemented with IBA. Papaya shoot explants absolutely formed ARs in peat medium after stem bases dipping in 1 mg mL(-1) IBA for 3 s. Our results indicate that the root-induction medium supplemented with agar and IBA would be mostly limited AR emergence and induced callus formation in SI explants, respectively. This study provides basic data for establishing a healthy and functional rooting system for in vitro papaya propagation.

Jasminum parkeri Dunn is a narrowly endemic, critically endangered woody ornamental shrub confined to sub-temperate zone of Western Himalayas, and rediscovered from its type locality after a lapse of about 100 years. In the present study, a propagation technique of J. parkeri, using stem cuttings, was established for the first time through application of auxins, namely, indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), and indole-3-butyric acid (IBA), at varying concentrations ranging from 1000 to 4000 ppm. The highest rooting percentage (98.33% (85.68% +/- 4.32)), number of primary roots (36), root length (29.68 cm) and survival percentage (96.67% (83.85% +/- 6.16)) were recorded for cuttings treated with 3000 ppm NAA. The phenological comparison between pot plants propagated through seeds and stem cuttings in a naturally ventilated polyhouse revealed a reduction in vegetative and flowering phases in cutting raised plants. Additionally, a noteworthy adaptive behavior of two weeks of early flowering and four weeks of extended flowering (February to October) was observed in plants raised under polyhouse conditions. This method will help in protecting the species from population decline, thereby significantly increasing its potential to be harnessed as an ornamental plant in India. Furthermore, plants grown ex situ will be reintroduced in natural populations.
