Worldwide, there are plants known as psychoactive plants that naturally contain psychedelic active components. They have a high concentration of neuroprotective substances that can interact with the nervous system to produce psychedelic effects. Despite these plants' hazardous potential, recreational use of them is on the rise because of their psychoactive properties. Early neuroscience studies relied heavily on psychoactive plants and plant natural products (NPs), and both recreational and hazardous NPs have contributed significantly to the understanding of almost all neurotransmitter systems. Worldwide, there are many plants that contain psychoactive properties, and people have been using them for ages. Psychoactive plant compounds may significantly alter how people perceive the world.

In this study, a series of 2- and/or 3-substituted juglone derivatives were designed and synthesized. Among them, 9, 18, 22, 30, and 31 showed stronger inhibition activity against cell surface PDI or recombinant PDI and higher inhibitory effects on U46619- and/or collagen-induced platelet aggregation than juglone. The glycosylated derivatives 18 and 22 showed improved selectivity for inhibiting the proliferation of multiple myeloma RPMI 8226 cells, and the IC50 values reached 61 and 48 nM, respectively, in a 72 h cell viability test. In addition, 18 and 22 were able to prevent tumor cell-induced platelet aggregation and platelet-enhanced tumor cell proliferation. The molecular docking showed the amino acid residues Gln243, Phe440, and Leu443 are important for the compound-protein interaction. Our results reveal the potential of juglone derivatives to serve as novel antiplatelet and anticancer dual agents, which are available to interrupt platelet-cancer interplay through covalent binding to PDI catalytic active site.

There is strong scientific evidence that the electric field is harmful to life. Exposure to an electric field (EF) can cause lung toxicity and respiratory disorders. In addition, the electric field has been shown to cause tissue damage through inflammation and apoptosis. Juglone (JUG) is one of the powerful antioxidants with anti-apoptotic and anti-inflammatory, various pharmacological properties in the biological system. In this study, we evaluated the efficacy of JUG against the potential adverse effects of electric field on the lung. Twenty-four Wistar albino rats were randomly divided into three groups; control group (Cont), EF group, and EF exposure+JUG-treated group (EJUG). After routine histological procedures, sections stained with hematoxylin-eosin (H&E) showed significant changes in lung tissues in the EF group compared to the Cont group. Significant protective effects were observed in the building volumes and histopathology in the EJUG group. Our immunohistochemical and gene expression results increased the expression of caspase-3 and tumor necrosis factor alpha (TNF-α) in the EF group (p < 0.05). Juglon increased cytokine signal suppressor (SOCS) expression (p < 0.001). These findings were consistent with the antioxidant effect of JUG treatment. We reasoned that exposure to EF damaged rat lung tissues and administration of JUG alleviated the complications caused by 50 Hz EF. Plain Language Summary: Depending on technological developments, the use of electric devices and equipment is increasing day by day. During the transmission and use of electrical energy, electric and magnetic fields occurs. This forces can affect the environment and people. 50 Hz electric fields damage the cells and tissues of exposed living things in many ways. In our study, we examined the hypothesis that juglone, a natural antioxidant, can reduce the damage caused by the 50 Hz electric field that we are exposed to for a long time in our daily lives. In our study, it was shown by histological and genetic approaches that juglone, which has antioxidant and anti-apoptotic effects, may be protective against lung damage due to electric field exposure on experimental animals. According to our study results, for increased electric field exposure as a consequence of developing technology, juglone could be an important supportive treatment option.

Electric field (EF) has been shown to cause tissue damage mainly through oxidative stress, inflammation, and apoptosis. Thus, juglone (5-hydroxy-1,4-naphthoquinone) (JUG), which has antioxidant and antiapoptotic properties, is thought to be effective against electric field-induced damage. We aimed to investigate whether 50 Hz alternating current (AC) triggers inflammation and apoptosis in rat liver and kidney tissues and evaluate the JUG supplement's estimated protective effect. Twenty-four adult male wistar albino rats were divided into control, EF and EF + JUG groups, each containing eight rats. The EF and EF + JUG groups were exposed to EF while no EF exposure and JUG were applied to the control group. At the end of the experiment, liver and kidney tissues were collected for histological (H&E, caspase-3 and TNF-α for immunohistochemical staining), and genetics (SOCS, caspase-3 and TNF-α, PCR analyses). After routine histological procedures, sections stained with H&E showed significant changes in liver and kidney tissues in the EF group compared to the control group (p < 0.05). Significant protective effects were observed in the building volumes and histopathology in the EF + JUG group (p < 0.05). Our gene expression results increased the expression of caspase-3 and TNF-α in the EF group (p < 0.001). Juglone increased SOCS expression (p < 0.001). These findings were consistent with the anti-apoptotic and anti-inflammatory effects of JUG treatment. We reasoned that exposure to EF damaged rat liver and kidney tissues and administration of JUG alleviated the complications caused by 50 Hz EF. Copyright © 2023 Elsevier Ltd. All rights reserved.

A series of 11-substituted 9-hydroxy-3,5,10,11-tetrahydro-2H-benzo[6,7]thiochromeno[2,3-d][1,3]thiazole-2,5,10-triones 3.1-3.13 were synthesized via hetero-Diels-Alder reaction of 5-ene-4-thioxo-2-thiazolidinones and 5-hydroxy-1,4-naphthoquinone (juglone). The structure of newly synthesized compounds was established by means of spectral data and a single-crystal X-ray diffraction analysis. The synthesized compounds were tested on a panel of cell lines representing different types of cancer as well as normal and pseudonormal cells and peripheral human blood lymphocytes. Compound 3.10 was found to be the most active derivative, exhibiting a cytotoxic effect similar to doxorubicin's one (IC50 ranged from 0.6 to 5.98 μM), but less toxic to normal and pseudonormal cells. All synthesized compounds were able to interact with DNA, although their anticancer activity did not correlate with the potency of interaction with DNA. The status of p53 in colorectal cancer cells correlated with the activity of the synthesized derivatives 3.1, 3.7, and 3.10. Compound 3.10 did not have an acute toxic effect on the body of С57BL/6 mice, unlike the well-known anticancer drug doxorubicin, which was used as a positive control. The injection of 3.10 (20 mg/kg) to mice had no effect on the counts of leukocytes, erythrocytes, platelets and hemoglobin level in their blood, in contrast to doxorubicin, which caused anemia and leukopenia, indicating bio-tolerance of 3.10in vivo.

Schistosomiasis remains one of the world's leading health concerns, affecting millions. The granulomatous reaction is the most significant immunopathological change associated with Schistosoma mansoni infection, resulting in significant mortality. Recent progress has been made in the search for new natural compounds to reduce schistosomiasis and its immunopathology. Walnuts contain the phenolic compound Juglone (5-hydroxy-1,4-naphthoquinone), which has antiparasitic, anti-inflammatory, immunoregulatory, and antioxidant properties. There were three groups of infected mice: untreated (IU), Juglone-treated (JUG T), and praziquantel-treated (PZ). In mice treated at 8 mg Juglone /kg body weight, a reduction of 63.1 % and 52.1 % were observed in the number of male and female worms, respectively. In addition, the number of eggs/g tissue was reduced by 65.7 % in the liver, 58.58 % in the intestine, and 62.31 % in the liver and intestine combined. In addition, Juglone decreased hepatic granuloma size by 55.1 % and collagen fiber deposition by 23.4 % compared to PZQ (41.18 % and 11.2 %, respectively). Interestingly, the JUG T group had significantly lower levels of IL-4, IL-13, IL-37, TNF-α, TGF-β, and IFN-γ than PZ mice (p < 0.05). While IL-10 and IL-17 levels rose (p < 0.01), Juglone could restore hepatic ALT, AST, GGT, and LDH activities following infection. In addition, it increased catalase, SOD, GSH, and GST while decreasing NO and LPO in comparison to the infected group. Moreover, anti-SWAP, SEA, and CAP IgG levels increased significantly. IgE levels did not change significantly, however. Juglone could be used as an antifibrotic, immunomodulatory, and schistosomicidal agent; thus, it could be used in place of PZQ.
