Neurotoxicol Teratol 2024; 106:107394. [PMID: 39303770 DOI: 10.1016/j.ntt.2024.107394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 09/05/2024] [Accepted: 09/15/2024] [Indexed: 09/22/2024]
Abstract
Although there have been reports indicating that Datura Stramonium (D. stramonium) may induce anticholinergic and neuropsychiatry effects, the compound is still being used for recreational and medicinal purposes while ingestion during pregnancy has been documented. Intriguingly, minimal studies have investigated the potential neurotoxic impact of D. stramonium exposure at various stages of gestation, including its potential implication on neurophysiological well-being later in life. The present study, therefore, examined spontaneous working memory and the expression of specific neurochemicals modulating crucial neural processes in adolescent rats exposed to high and low D. stramonium doses during different stages of gestation. Pregnant rats were orally infused with 150- or 500- mg/kg/day of D. stramonium either during mid- (second week; days 8-14) or late- (third week; days 15-21) gestation, while control rats received PBS at dosing periods. Behavioral characterization of offspring between postnatal days (PD) 40 and 41 in the Y-maze revealed that D. stramonium perturbed spatial working memory in rats, although locomotor activity was generally unaltered. In addition to SOD and nitric oxide downregulation, induction of oxidative stress in the hippocampus and prefrontal cortex (PFC) of young adult rats prenatally exposed to D. stramonium was corroborated by depletion of key antioxidant regulatory elements glutathione peroxidase, glutathione reductase and catalase, which was accompanied by lipid peroxidation shown by increased MDA levels. Whereas increased expression of acetylcholinesterase and LDH was seen in adolescent rats prenatally infused D. stramonium, acetylcholine levels were downregulated in both hippocampal and PFC lysates, suggesting cholinergic and metabolic dysfunctions. Immunohistochemical labelling of GFAP and IBA-1 revealed increased expression of reactive astrocytes and microglia respectively, while the accompanying TNFα upregulation in both the hippocampus (dentate gyrus) and PFC causally linked intrauterine D. stramonium exposure with neuroinflammatory responses postnatally. Overall, our data correlated postnatal spatial working memory dysfunction evoked by D. stramonium exposure during critical stages of embryonic development to oxidative redox impairment, cholinergic disruption and neuroinflammatory perturbations in rats.

[PMID: 38693106 PMCID: PMC11063156 DOI: 10.1038/s41420-024-01974-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Revised: 04/17/2024] [Accepted: 04/17/2024] [Indexed: 05/03/2024] Open
Abstract
Depression is highly prevalent globally, however, currently available medications face challenges such as low response rates and short duration of efficacy. Additionally, depression mostly accompany other psychiatric disorders, further progressing to major depressive disorder without long-term effective management. Thus, sustained antidepressant strategies are urgently needed. Recently, ketamine and psilocybin gained attention as potential sustained antidepressants. Review of recent studies highlights that synaptic plasticity changes as key events of downstream long-lasting changes in sustained antidepressant effect. This underscores the significance of synaptic plasticity in sustained antidepressant effect. Moreover, neurexins, key molecules involved in the regulation of synaptic plasticity, act as critical links between synaptic plasticity and sustained antidepressant effects, involving mechanisms including protein level, selective splicing, epigenetics, astrocytes, positional redistribution and protein structure. Based on the regulation of synaptic plasticity by neurexins, several drugs with potential for sustained antidepressant effect are also discussed. Focusing on neurexins in regulating synaptic plasticity promises much for further understanding underlying mechanisms of sustained antidepressant and the next step in new drug development. This research represents a highly promising future research direction.

Toxins (Basel) 2023; 15:671. [PMID: 38133175 PMCID: PMC10747985 DOI: 10.3390/toxins15120671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 11/09/2023] [Accepted: 11/18/2023] [Indexed: 12/23/2023] Open
Abstract
INTRODUCTION In a few regions of the globe, deliberate botanical intoxication may induce significant rates of toxicity and fatality. The objective of this report was to describe plant self-intoxication using the experiences of the southeastern France poison control center (PCC) between 2002 and 2021. RESULTS During those 20 years, 262 deliberate plants poisonings were reported involving 35 various plants. In most of the cases, poisoning was caused by Nerium oleander (n = 186, 71%), followed by the Datura genus (4.2%), Ricinus communis (3.8%), Taxus baccata (1.9%), Digitalis purpurea (1.2%), Aconitum nape (1.9%), Myristica fragans (1.5%), and Pyracantha coccine (1.2%). Through the 262 plants poisonings, 19 patients among the 186 Nerium oleander poisonings received Digifab as an antidote and 1 patient received physostigmine among the 11 Datura poisonings. Only four deaths were reported for this review, each involving Nerium oleander. DISCUSSION The first involved species was Nerium oleander (71% of all plants poisonings), then Datura sp and Ricinus communis. It is explained by this native local species' important repartition. Most patients must be admitted to an emergency department for adapted medical care; however, only 41 of them described severe poisonings symptoms. Even fewer needed an antidote, only 20 patients. There is no protocol for the use of a specific treatment, and it might be interesting to develop one for this purpose. MATERIAL AND METHODS This retrospective review was realized with files managed by the southeastern France PCC based in Marseille from 2002 to 2021. Our department covers the complete French Mediterranean coast, Corsica, and tropical islands (Reunion Island, Mayotte). For every patient, toxicity was evaluated using the Poison Severity Score (PSS).

Datura metel stramonium exacerbates behavioral deficits, medial prefrontal cortex, and hippocampal neurotoxicity in mice via redox imbalance. Lab Anim Res 2023; 39:15. [PMID: 37381025 DOI: 10.1186/s42826-023-00162-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 05/17/2023] [Accepted: 05/30/2023] [Indexed: 06/30/2023] Open
Abstract
BACKGROUND Datura metel (DM) stramonium is a medicinal plant often abused by Nigerians due to its psychostimulatory properties. Hallucinations, confusion, agitation, aggressiveness, anxiety, and restlessness are reported amongst DM users. Earlier studies suggest that DM induces neurotoxicity and affect brain physiology. However, the exact neurological effects of DM extract in the medial prefrontal cortex (mPFC) and hippocampal morphology have not been elucidated. In this study, we evaluated the hypothesis that oral exposure to DM extract exerts a neurotoxic effect by increasing oxidative stress in the mPFC and the hippocampus and induces behavioral deficits in mice. RESULTS DM methanolic extract exposure significantly increased MDA and NO levels and reduced SOD, GSH, GPx and CAT activities in mice brains. In addition, our results showed that DM exposure produced cognitive deficits, anxiety, and depressive-like behaviour in mice following oral exposure for 28 days. Moreover, the mPFC and hippocampus showed neurodegenerative features, loss of dendritic and axonal arborization, a dose-dependent decrease in neuronal cell bodies' length, width, area, and perimeter, and a dose-dependent increase in the distance between neuronal cell bodies. CONCLUSIONS Oral exposure to DM in mice induces behavioural deficits, mPFC and hippocampal neuronal degenerations via redox imbalance in the brain of mice. These observations confirm the neurotoxicity of DM extracts and raises concerns on the safety and potential adverse effects of DM in humans.

Abstract
The study of plant metabolism is one of the most complex tasks, mainly due to the huge amount and structural diversity of metabolites, as well as the fact that they react to changes in the environment and ultimately influence each other. Metabolic profiling is most often carried out using tools that include mass spectrometry (MS), which is one of the most powerful analytical methods. All this means that even when analyzing a single sample, we can obtain thousands of data. Data science has the potential to revolutionize our understanding of plant metabolism. This review demonstrates that machine learning, network analysis, and statistical modeling are some techniques being used to analyze large quantities of complex data that provide insights into plant development, growth, and how they interact with their environment. These findings could be key to improving crop yields, developing new forms of plant biotechnology, and understanding the relationship between plants and microbes. It is also necessary to consider the constraints that come with data science such as quality and availability of data, model complexity, and the need for deep knowledge of the subject in order to achieve reliable outcomes.

Abstract
Even in modern times, the popularity level of medicinal plants and herbal medicines in therapy is still high. The World Health Organization estimates that 80% of the population in developing countries uses these types of remedies. Even though herbal medicine products are usually perceived as low risk, their potential health risks should be carefully assessed. Several factors can cause the toxicity of herbal medicine products: plant components or metabolites with a toxic potential, adulteration, environmental pollutants (heavy metals, pesticides), or contamination of microorganisms (toxigenic fungi). Their correct evaluation is essential for the patient’s safety. The toxicity assessment of herbal medicine combines in vitro and in vivo methods, but in the past decades, several new techniques emerged besides conventional methods. The use of omics has become a valuable research tool for prediction and toxicity evaluation, while DNA sequencing can be used successfully to detect contaminants and adulteration. The use of invertebrate models (Danio renio or Galleria mellonella) became popular due to the ethical issues associated with vertebrate models. The aim of the present article is to provide an overview of the current trends and methods used to investigate the toxic potential of herbal medicinal products and the challenges in this research field.

Abstract
The relationship between man and substances that have abuse potentials, and whose use has been associated with the development or progression of substance use disorders has continued to evolve in terms of geography, economic implications, and time. History shows that local plants with psychoactive constituents can get exported worldwide through global travel, commerce, or even conquest. Time and globalization also change people’s relationship with substances of abuse; hence, an area that was initially alien to certain substances might evolve to becoming a trafficking hub, and then a destination. A case in point is Africa where a rapidly increasing prevalence of substance use/abuse and substance use disorder among adolescents and young adults is putting enormous strain on the economy, healthcare system, and society at large. However, there appears to be a paucity of scientific literature and data on the epidemiology, risk assessment, and contributing factors to substance use and the development of substance use disorders across Africa. In this narrative review, we examine extant literature (PubMed, Google scholar, Medline) for information on the prevalence, trends, and influencers of substance use and the development of substance use disorders. This is with a view of understanding the determinants of substance use and factors that influence the development of substance use disorders in the region, and how this information can be channeled towards developing a comprehensive intervention and treatment program.

Abstract
The characteristic growth habit, abundant green foliage, and aromatic inflorescences of cannabis provide the plant with an ideal profile as an ornamental plant. However, due to legal barriers, the horticulture industry has yet to consider the ornamental relevance of cannabis. To evaluate its suitability for introduction as a new ornamental species, multifaceted commercial criteria were analyzed. Results indicate that ornamental cannabis would be of high value as a potted-plant or in landscaping. However, the readiness timescale for ornamental cannabis completely depends on its legal status. Then, the potential of cannabis chemotype Ⅴ, which is nearly devoid of phytocannabinoids and psychoactive properties, as the foundation for breeding ornamental traits through mutagenesis, somaclonal variation, and genome editing approaches has been highlighted. Ultimately, legalization and breeding for ornamental utility offers boundless opportunities related to economics and executive business branding.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Brugmansia belongs to the Solanaceae family and contains approximately 7-8 species distributed in America, Europe, Africa, and Asia. The genus Brugmansia plants are used in the traditional medicine of different parts of the world for the treatment of inflammations, rheumatic arthritis, wounds, skin infections, headache, asthma, colic, aches, and so on. AIM OF THE REVIEW To the best of our knowledge, this is the first review study that focuses on the phytochemistry, pharmacology, toxicity, and traditional uses of Brugmansia species in order to understand the link between the traditional uses, phytochemistry, and modern therapeutic uses, and provide a scientific fundamental for further research in the phytochemical and pharmacological activities of their species. MATERIALS AND METHODS The information reported in this study was retrieved from the scientific database such as ScienceDirect, PubMed, Springer, CNKI, Wiley, Google Scholar, and Baidu Scholar, up until May 2020. The key search word was "Brugmansia." Additionally, information was derived by search on the reference lists of included articles and Ph.D. dissertations. RESULTS As traditional uses, Brugmansia species are used against a wide range of diseases such as body pain, inflammatory conditions, skin infection, wound, and other diseases. Also, these species are used as a hallucinogen, protection from evil, and magical rituals. Phytochemical investigations have led to reporting approximately 189 chemical compounds in this genus. Among these components, tropane alkaloids, terpenes, and flavonoids are the most representative components of Brugmansia species. The plant extracts and chemical constituents of Brugmansia species exhibit a broad spectrum of biological and pharmacological activities, including anti-inflammatory, cytotoxic, antioxidant, antibacterial, antispasmodic, anti-asthmatic, antinociceptive, antiprotozoal activities, and so on. CONCLUSION This review summarized and analyzed the information of traditional uses, phytochemical, pharmacological activities, and toxicity of the genus Brugmansia plants, which show their species have interesting chemical constituents with different biological activities. The traditional uses of some species from this genus have been estimated by pharmacological activities, such as the anti-inflammatory, antispasmodic, antiasthma, antinociceptive, anti-addictive, and antiprotozoal activity. However, the traditional uses of many species have not been confirmed, also the secondary metabolites of the many species have not yet been determined and have never been pharmacologically estimated. Considerably more research is needed to assert the ethnopharmacological uses, determine the chemical constituents, toxicity, and pharmacological activities of the genus Brugmansia species. The present review will be helpful for further research in the phytochemistry and pharmacology of Brugmansia species.

Abstract
The genus Datura (Solanaceae) contains nine species of medicinal plants that have held both curative utility and cultural significance throughout history. This genus’ particular bioactivity results from the enormous diversity of alkaloids it contains, making it a valuable study organism for many disciplines. Although Datura contains mostly tropane alkaloids (such as hyoscyamine and scopolamine), indole, beta-carboline, and pyrrolidine alkaloids have also been identified. The tools available to explore specialized metabolism in plants have undergone remarkable advances over the past couple of decades and provide renewed opportunities for discoveries of new compounds and the genetic basis for their biosynthesis. This review provides a comprehensive overview of studies on the alkaloids of Datura that focuses on three questions: How do we find and identify alkaloids? Where do alkaloids come from? What factors affect their presence and abundance? We also address pitfalls and relevant questions applicable to natural products and metabolomics researchers. With both careful perspectives and new advances in instrumentation, the pace of alkaloid discovery—from not just Datura—has the potential to accelerate dramatically in the near future.
