The hepatoprotective effect of 4-phenyltetrahydroquinolines on carbon tetrachloride induced hepatotoxicity in rats through autophagy inhibition. Biol Res 2024; 57:32. [PMID: 38797855 PMCID: PMC11129499 DOI: 10.1186/s40659-024-00510-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 04/25/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND The liver serves as a metabolic hub within the human body, playing a crucial role in various essential functions, such as detoxification, nutrient metabolism, and hormone regulation. Therefore, protecting the liver against endogenous and exogenous insults has become a primary focus in medical research. Consequently, the potential hepatoprotective properties of multiple 4-phenyltetrahydroquinolines inspired us to thoroughly study the influence of four specially designed and synthesized derivatives on carbon tetrachloride (CCl4)-induced liver injury in rats. METHODS AND RESULTS Seventy-seven Wistar albino male rats weighing 140 ± 18 g were divided into eleven groups to investigate both the toxicity profile and the hepatoprotective potential of 4-phenyltetrahydroquinolines. An in-vivo hepatotoxicity model was conducted using CCl4 (1 ml/kg body weight, a 1:1 v/v mixture with corn oil, i.p.) every 72 h for 14 days. The concurrent treatment of rats with our newly synthesized compounds (each at a dose of 25 mg/kg body weight, suspended in 0.5% CMC, p.o.) every 24 h effectively lowered transaminases, preserved liver tissue integrity, and mitigated oxidative stress and inflammation. Moreover, the histopathological examination of liver tissues revealed a significant reduction in liver fibrosis, which was further supported by the immunohistochemical analysis of α-SMA. Additionally, the expression of the apoptotic genes BAX and BCL2 was monitored using real-time PCR, which showed a significant decrease in liver apoptosis. Further investigations unveiled the ability of the compounds to significantly decrease the expression of autophagy-related proteins, Beclin-1 and LC3B, consequently inhibiting autophagy. Finally, our computer-assisted simulation dockingonfirmed the obtained experimental activities. CONCLUSION Our findings suggest that derivatives of 4-phenyltetrahydroquinoline demonstrate hepatoprotective properties in CCl4-induced liver damage and fibrosis in rats. The potential mechanism of action may be due to the inhibition of autophagy in liver cells.

Abstract
Medicinal insects play an important role in the treatment of refractory diseases due to their unique and rich pharmacological activities. However, compared to plants, microorganisms, and marine organisms, medicinal insects have been largely ignored. Some small molecules isolated from insects are known to have defensive effects, but their majority roles remain unknown. In-depth research on the small molecules of medicinal insects has been conducted in recent years. Then alkaloids, dopamine derivatives, nucleoside derivatives, and other components are obtained. Among them, dopamine derivatives are a unique class of components from medicinal insects. Thus, we present a comprehensive overview of chemical structures and biological activities of dopamine derivatives from some medicinal insects, which will bring more attention to other researchers for further chemical and biological investigations on the unique dopamine derivatives as well as medicinal insects.

Abstract
Insects are a significant source of food for millions of people worldwide. Since ancient times, insects in medicine have been contributing to the treatment of diseases in humans and animals. Compared to conventional animal farming, the production of insects for food and feed generates significantly less greenhouse gas emissions and uses considerably less land. Edible insects provide many ecosystem services, including pollination, environmental health monitoring, and the decomposition of organic waste materials. Some wild edible insects are pests of cash crops. Thus, harvesting and consuming edible insect pests as food and utilizing them for therapeutic purposes could be a significant progress in the biological control of insect pests. Our review discusses the contribution of edible insects to food and nutritional security. It highlights therapeutic uses of insects and recommends ways to ensure a sustainable insect diet. We stress that the design and implementation of guidelines for producing, harvesting, processing, and consuming edible insects must be prioritized to ensure safe and sustainable use.

Abstract
Edible insects are commonly consumed across the world because of their size, availability, and nutritional benefits. They have also been recommended as a potential solution to food shortage because of their high nutritional value. In this study, we demonstrated the immunological effects of Gryllus bimaculatus on RAW 264.7 cells and splenocytes obtained from mouse. This is the first study to evaluate the immunological effects of G. bimaculatus water extract. Innate and adaptive immunity were evaluated and measured in RAW 264.7 cells and/or mouse splenocytes using a cell viability assay; changes in cytokine abundance, nitric oxide production, and cell surface molecule abundance were determined using flow cytometry; and western blotting analysis was performed for various immune signaling pathways. G. bimaculatus water extract showed no cytotoxicity in cells, and the results suggest that treatment with G. bimaculatus water extract can induce macrophage activation through mitogen-activated protein kinase and nuclear factor-κB signaling, induction of proinflammatory cytokines [interleukin (IL)-6, IL-1β, and tumor necrosis factor-α] and activation of the expression of cell surface molecules [cluster of differentiation (CD)80, CD86, major histocompatibility complex (MHC) class I, and MHC class II]. Treatment with G. bimaculatus water extract increased the production of cytokines (IL-2, IL-4, and interferon-γ) in splenocytes. The results indicate that G. bimaculatus water extract can regulate innate and adaptive immunity via modulation macrophages and splenocytes activation and can serve as an immunological agent. We inferred that G. bimaculatus is a safe and efficient natural material that enhances immunological activity.

Abstract
Consumption of edible insects has been widely suggested as an environmentally sustainable substitute for meat to reduce GHG emissions. However, the novel research field for edible insects rely on the content of bioactive ingredients and on the ability to induce a functional effect in humans. The goal of this manuscript was to review the available body of evidence on the properties of edible insects in modulating oxidative and inflammatory stress, platelet aggregation, lipid and glucose metabolism and weight control. A search for literature investigating the functional role of edible insects was carried out in the PUBMED database using specific keywords. A total of 55 studies, meeting inclusion criteria after screening, were divided on the basis of the experimental approach: in vitro studies, cellular models/ex vivo studies or in vivo studies. In the majority of the studies, insects demonstrated the ability to reduce oxidative stress, modulate antioxidant status, restore the impaired activity of antioxidant enzymes and reduce markers of oxidative damage. Edible insects displayed anti-inflammatory activity reducing cytokines and modulating specific transcription factors. Results from animal studies suggest that edible insects can modulate lipid and glucose metabolism. The limited number of studies focused on the assessment of anticoagulation activity of edible insects make it difficult to draw conclusions. More evidence from dietary intervention studies in humans is needed to support the promising evidence from in vitro and animal models about the functional role of edible insects consumption.

Abstract
Covering: 2015 up to the end of 2020Even in the golden age of NMR, the number of natural products being incorrectly assigned is becoming larger every day. The use of quantum NMR calculations coupled with sophisticated data analysis provides ideal complementary tools to facilitate the elucidation process in challenging cases. Among the current computational methodologies to perform this task, the DP4+ probability is a popular and widely used method. This updated version of Goodman's DP4 synergistically combines NMR calculations at higher levels of theory with the Bayesian analysis of both scaled and unscaled data. Since its publication in late 2015, the use of DP4+ to solve controversial natural products has substantially grown, with several predictions being confirmed by total synthesis. To date, the structures of more than 200 natural products were determined with the aid of DP4+. However, all that glitters is not gold. Besides its intrinsic limitations, on many occasions it has been improperly used with potentially important consequences on the quality of the assignment. Herein we present a critical revision on how the scientific community has been using DP4+, exploring the strengths of the method and how to obtain optimal results from it. We also analyze the weaknesses of DP4+, and the paths to by-pass them to maximize the confidence in the structural elucidation.
