Dual Catalytic Synthesis of Antiviral Compounds Based on Metallocarbene-Azide Cascade Chemistry

Aryl azides trap ortho-metallocarbene intermediates to generate indolenones possessing a reactive C-acylimine moiety, which can react with added indole nucleophiles to afford the 2-(3-indolyl)indolin-3-one scaffold found in the antiviral natural product isatisine A. This overall process occurs through a dual catalytic sequence at room temperature. Redox activation of the Cu(OTf)(2) precatalyst by indole results in catalytically competent Cu(I) required for azide-metal-locarbene coupling. The Bronsted acid that is also formed from Cu(OTf)(2) reduction is responsible for catalysis of the C-C bond-forming indole addition step. This modular, procedurally simple method allows for rapid assembly of bis(indole) libraries, several of which proved to have anti-infective activity against respiratory syncytial virus and Zika virus.

Application of 58-61-7, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 58-61-7.

Recent Advances in the Electrochemical Synthesis and Functionalization of Indole Derivatives

The chemists’ pursuit of the ideal synthesis and functionalization of indole derivatives has lasted over 150 years as their scaffolds have been widely found in natural products, pharmaceuticals, agrochemicals and organic materials. In this regard, the recent resurgence of adopting green and sustainable electrochemistry in organic synthesis suggests that electrosynthesis is a promising strategy. Indeed, many new intriguing applications of synthesis and functionalization of indole derivatives by direct and redox-mediated electrochemical means have been disclosed. In this review, we highlight the fundamental aspects, reaction scopes, synthetic applications and reaction mechanisms of the electrochemical synthesis and functionalization of indole derivatives.

Impacts of dietary supplementation with p-coumaric acid and indole-3-acetic acid on survival and biochemical response of honey bees treated with tau-fluvalinate

Pollinator populations are in decline worldwide. Multiple factors have been cited as potential causes to these declines. In honey bees, a combination of stressors is known to cause colony losses. Adequate nutrition is a key factor for honey bee growth and colony development. Several studies show that the nutritional quality of the diet is directly proportional to the ability of the bee to face challenges or stressors. We explored the effect of p-coumaric (600 mu M) and indole-3-acetic acid (2, 20 or 200 mu M) supplementation on the survival and activity of key detoxification enzymes of honey bees exposed to tau-fluvalinate. The dietary supplementation with p-coumaric and indole-3-acetic acids (20 mu M) enhanced the survival of bees exposed to tau-fluvalinate (approximately 20%). We also showed that dietary p-coumaric acid increased the levels of cytochrome P450 and glutathione reductase activity in bees treated with tau-fluvalinate, as well as in the untreated controls, while glutathione-S-transferase activity was lower in treated bees than in untreated. In bees fed with indole-3-acetic acid, cytochrome P450 showed increased levels, however, glutathione-S-transferase showed the lowest activity. Moreover, the results showed that supplementation with p-coumaric and indole-3-acetic acids did not alter acetyl cholinesterase activity, nor did treatment with tau-fluvalinate. Altogether, the enzymatic changes related to the detoxification mechanisms observed in bees that were fed with p-coumaric and indole-3-acetic acids could be responsible for the increased survival of bees treated with tau-fluvalinate compared to those that received a control diet. The results presented in this study, together with previous studies, provide evidence of the importance of dietary phytochemicals in the response of honey bees to pesticide exposure. Moreover, these results are the first report of the beneficial effect of the phytohormone indole-3-acetic acid on the survival of honey bees treated with tau-fluvalinate.

Strong-field ionization of complex molecules

Strong-field photoelectron momentum imaging of the prototypical biomolecule indole is disentangled in a combined experimental and computational approach. Experimentally, strong control over the molecules enables the acquisition of photoelectron momentum distributions in the molecular frame for a well-defined narrow range of incident intensities. A highly efficient semiclassical simulation setup based on the adiabatic tunneling theory quantitatively reproduces these results. Jointly, experiment and computations reveal holographic structures in the asymptotic momentum distributions, which are found to sensitively depend on the alignment of the molecular frame. We identify the essential molecular properties that shape the photoelectron wave packet in the first step of the ionization process and employ a quantum-chemically exact description of the cation during the subsequent continuum dynamics. The detailed modeling of the molecular ion, which accounts for its polarization by the laser electric field, enables the accurate description of the photoelectron dynamics in close vicinity of the molecule. Our approach provides full insight into the photoelectron’s dynamics in terms of semiclassical trajectories and aims at the simulation and unraveling of strong-field diffractive imaging of biomolecular systems on femtosecond timescales.

Physiological and transcription analyses reveal the regulatory mechanism of melatonin in inducing drought resistance in loquat (Eriobotrya japonica Lindl.) seedlings

Drought limits the growth and development of loquat (Eriobotrya japonica Lindl.) seedlings. Although melatonin (MT) is a naturally occurring small molecule in plants and has been linked with response to drought stress, the underlying mechanism remains largely unknown. The protective effects and regulatory mechanisms of MT on the regulation of drought stress in grafted loquat seedlings were analyzed in this study. The physiological results showed that MT effectively mitigated chlorophyll degradation and malondialdehyde (MDA) accumulation in the loquat leaves under drought stress. In addition, MT improved the photosynthetic efficiency and starch content of grafted loquat seedlings. Transcriptome results revealed that MT regulated genes involved in the Ca2+ signal transduction (cyclic nucleotide gated channel, CNGCs and cam modulin/ calmodulin-like protein, CAM/CMLs), starch and sucrose metabolism (sucrose synthase, SuS5 and SuS6), and plant hormone signal transduction (ABA receptor, PYL4; protein phosphatase 2C, PP2Cs; auxin/indole acetic acid protein, AUX/IAAs and ethylene responsive transcription factor 1B, ERF1B), and the transcription factors such as WRKYs, NACs, ERFs, and bHLHs. We highlighted the analysis on phytohormone signaling pathways and their possible crosstalk. The results also demonstrated that MT increased the endogenous MT, IAA and CTK contents, while decreasing the ABA content under drought condition. Taken together, these results provided a new perspective on the role of MT in drought stress and a network for gene function analysis in MT-mediated signaling pathways.
