Modulation of cholesterol metabolism with Phytoremedies in Alzheimer's disease: A comprehensive review. Ageing Res Rev 2024; 99:102389. [PMID: 38906182 DOI: 10.1016/j.arr.2024.102389] [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: 04/20/2024] [Revised: 06/18/2024] [Accepted: 06/18/2024] [Indexed: 06/23/2024]
Abstract
Alzheimer's disease (AD) is a complex neurological ailment that causes cognitive decline and memory loss. Cholesterol metabolism dysregulation has emerged as a crucial element in AD pathogenesis, contributing to the formation of amyloid-beta (Aβ) plaques and tau tangles, the disease's hallmark neuropathological characteristics. Thus, targeting cholesterol metabolism has gained attention as a potential therapeutic method for Alzheimer's disease. Phytoremedies, which are generated from plants and herbs, have shown promise as an attainable therapeutic option for Alzheimer's disease. These remedies contain bioactive compounds like phytochemicals, flavonoids, and polyphenols, which have demonstrated potential in modulating cholesterol metabolism and related pathways. This comprehensive review explores the modulation of cholesterol metabolism by phytoremedies in AD. It delves into the role of cholesterol in brain function, highlighting disruptions observed in AD. Additionally, it examines the underlying molecular mechanisms of cholesterol-related pathology in AD. The review emphasizes the significance of phytoremedies as a potential therapeutic intervention for AD. It discusses the drawbacks of current treatments and the need for alternative strategies addressing cholesterol dysregulation and its consequences. Through an in-depth analysis of specific phytoremedies, the review presents compelling evidence of their potential benefits. Molecular mechanisms underlying phytoremedy effects on cholesterol metabolism are examined, including regulation of cholesterol-related pathways, interactions with Aβ pathology, influence on tau pathology, and anti-inflammatory effects. The review also highlights challenges and future perspectives, emphasizing standardization, clinical evidence, and personalized medicine approaches to maximize therapeutic potential in AD treatment. Overall, phytoremedies offer promise as a potential avenue for AD management, but further research and collaboration are necessary to fully explore their efficacy, safety, and mechanisms of action.

Mahmoud EI, Yousif MA, Arbab AH. Attitude and Practice of Pharmacy Students Toward Traditional Herbal Medicines, Sudan. INTEGRATED PHARMACY RESEARCH AND PRACTICE 2024; 13:61-68. [PMID: 38827648 PMCID: PMC11143999 DOI: 10.2147/iprp.s465056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 05/22/2024] [Indexed: 06/04/2024] Open
Abstract
Purpose Traditional herbal medicines (THMs) are widely used in Sudan, but there is scarcity of research on pharmacy students' attitudes and utilization of THMs. This study aims to assess the attitudes and practices of pharmacy students toward THM. Methods A descriptive cross-sectional study was conducted among randomly selected undergraduate pharmacy students at the University of Khartoum (Sudan). Data were collected using a validated self-administered questionnaire adapted from previous studies. A statistical package for the social sciences was used for data analysis. Results Among the 264 respondents, the average age was 21.8 years, and 84.8% of them were females. Nearly 85% of respondents were residents of Khartoum. The overall respondent's attitudes towards THMs were positive, it ranged from high (19.7%), moderate (79.9%). About 87.8% of respondents are interested in learning more about THMs. In addition, 36.4%, and 50.4% of respondents strongly agreed or agreed that THMs should be officially licensed and controlled. A 17.8% and 63.3% of respondents, respectively, reported using traditional herbal remedies either always or occasionally. Supermarkets (35.2%) and friends/family (36.4%) were the main sources of THMs for the participants, and oral administration was the most used route (87.1%). More than 90% of respondents said they would suggest THMs to others, and the most common justifications for doing so were their accessibility (46.6%) and affordability (16.3%). The most widely used herbs were Mentha spicata, Zingiber officinale, Acacia nilotica, Hibiscus sabdariffa, and Syzygium aromaticum. Data revealed a significant association between attitude levels and respondents' gender (p=0.046), year of study (p=0.000), and residence (p=0.017). Conclusion Most undergraduate pharmacy students had a positive attitude and utilized THMs. Development of effective educational initiatives, research, and regulations are recommended to ensure the appropriate utilization of traditional herbal remedies.

Abstract
OBJECTIVES Medicinal herbs are plants with potential medicinal and health benefits. In recent years, they are being increasingly used as a treatment alternative owing to their effectiveness against various diseases. In this study, we investigated the inhibitory effects of 15 medicinal herbs on causative bacteria for dental caries and periodontal disease. METHODS This study evaluated the effects of the extracts of 15 medicinal herbs on growth and biofilm formation in five oral pathogenic bacterial strains. The herbs were processed into extracts, and bacterial strains were cultured. Then, bacterial growth and biofilm formation were assessed using various methods. Finally, the extract of the herb Hibiscus sabdariffa (hibiscus) was analyzed using high-performance liquid chromatography. RESULTS Incubation of bacteria with the herbal extracts showed that hibiscus exerted a significant inhibitory effect on all the oral pathogenic bacterial strains evaluated in this study. In addition, the pigment delphinidin-3-sambubioside, which is found in hibiscus extract, was identified as a particularly important inhibitory component. CONCLUSIONS These results lay the ground work for the potential development of novel therapeutic or preventive agents against dental caries and periodontal disease, two major oral diseases.

Abstract
Plant-based materials are an important source of bioactive compounds (BC) with interesting industrial applications. Therefore, adequate experimental strategies for maximizing their recovery yield are required. Among all procedures for extracting BC (maceration, Soxhlet, hydro-distillation, pulsed-electric field, enzyme, microwave, high hydrostatic pressure, and supercritical fluids), the ultrasound-assisted extraction (UAE) highlighted as an advanced, cost-efficient, eco-friendly, and sustainable alternative for recovering BC (polyphenols, flavonoids, anthocyanins, and carotenoids) from plant sources with higher yields. However, the UAE efficiency is influenced by several factors, including operational variables and extraction process (frequency, amplitude, ultrasonic power, pulse cycle, type of solvent, extraction time, solvent-to-solid ratio, pH, particle size, and temperature) that exert an impact on the molecular structures of targeted molecules, leading to variations in their biological properties. In this context, a diverse design of experiments (DOEs), including full or fractional factorial, Plackett-Burman, Box-Behnken, Central composite, Taguchi, Mixture, D-optimal, and Doehlert have been investigated alone and in combination to optimize the UAE of BC from plant-based materials, using the response surface methodology and mathematical models in a simple or multi-factorial/multi-response approach. The present review summarizes the advantages and limitations of the most common DOEs investigated to optimize the UAE of bioactive compounds from plant-based materials.

Abstract
Hibiscus sabdariffa (HS), commonly known as Roselle, has a rich history of traditional uses and is recognized for its diverse pharmacological properties, including antihypertensive, anti-inflammatory, antimicrobial, and more. This comprehensive review synthesizes the existing literature on the health benefits associated with the consumption of HS or its ingredients. Key areas of focus include metabolic health, blood sugar, and lipid regulation, wherein studies have reported varying effects on parameters such as fasting blood glucose, insulin sensitivity, and lipid profiles. Furthermore, Roselle exhibits anti-inflammatory properties, as evidenced by its impact on inflammatory markers such as MCP-1 and TNF-α. Additionally, HS extracts have shown notable antibacterial efficacy against various strains, with a potential role in urinary tract infection management. Studies also suggest potential benefits for renal function, with improvements in markers such as blood urea nitrogen and creatinine levels. In this article, we aim to review the existing literature on the health benefits of HS.

Abstract
TGF-β1, a key fibrotic cytokine, enhances both the expression and translocation of the activating transcriptional factor 4 (ATF4) and activates the serine/glycine biosynthesis pathway, which is crucial for augmenting collagen production. Targeting the TGF-β1-ATF4-serine/glycine biosynthesis pathway might offer a promising therapeutic approach for fibrotic diseases. In this study, we aimed to identify a proline-containing dipeptide in Hibiscus sabdariffa plant cells that modulates collagen synthesis. We induced Hibiscus sabdariffa plant cells and screened for a proline-containing dipeptide that can suppress TGF-β1-induced collagen synthesis in fibroblasts. Analyses were conducted using LC-MS/MS, RT-qPCR, Western blot analysis, and immunocytochemistry. We identified Gly-Pro (GP) from the extract of Hibiscus sabdariffa plant cells as a dipeptide capable of suppressing TGF-β1-induced collagen production. GP inhibited the phosphorylation of Smad2/3 and reduced the expression of ATF4, which is upregulated by TGF-β1. Notably, GP also decreased the expression of enzymes involved in the serine/glycine biosynthesis and glucose metabolism pathways, such as PHGDH, PSAT1, PSPH, SHMT2, and SLC2A1. Our findings indicate that the peptide GP, derived from Hibiscus sabdariffa plant cells, exhibits potent anti-fibrotic effects, potentially through its regulation of the TGF-β1-ATF4-serine/glycine biosynthesis pathway.

Abstract
The interest in the consumption of edible flowers has increased since they represent a rich source of bioactive compounds, which are significantly beneficial to human health. The objective of this research was to access the bioactive compounds and antioxidant and cytotoxic properties of unconventional alternative edible flowers of Hibiscus acetosella Welw. Ex Hiern. The edible flowers presented pH value of 2.8 ± 0.00, soluble solids content of 3.4 ± 0.0 °Brix, high moisture content of about 91.8 ± 0.3%, carbohydrates (6.9 ± 1.2%), lipids (0.90 ± 0.17%), ashes (0.4 ± 0.0%), and not detectable protein. The evaluation of the scavenging activity of free radicals, such as 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), of the flower extract was better than the results observed for other edible flowers (507.8 ± 2.7 μM TE and 783.9 ± 30.8 μM TE, respectively) as well as the total phenolic composition (TPC) value (568.8 ± 0.8 mg GAE/g). These flowers are rich in organic acids and phenolic compounds, mainly myricetin, and quercetin derivatives, kaempferol, and anthocyanins. The extract showed no cytotoxicity for the cell lineages used, suggesting that the extract has no directly harmful effects to cells. The important bioactive compound identified in this study makes this flower especially relevant in the healthy food area due to its nutraceutical potential without showing cytotoxicity.

Hibiscus sabdariffa (Roselle) calyx: a systematic and meta-analytic review of memory-enhancing, anti-neuroinflammatory and antioxidative activities. Inflammopharmacology 2023; 31:231-240. [PMID: 36436183 DOI: 10.1007/s10787-022-01101-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 11/09/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND In this study, we summarized the preclinical investigations of the neuroprotective activities of Hibiscus sabdariffa (HSD) extract via its effect on memory function, neuroinflammation and oxidative damage in the central nervous system, which may help to guide future studies. METHODS Preclinical studies that investigated the effect of HSD extract on memory impairment, neuroinflammation and oxidative stress-induced neuronal damage were searched systematically in PubMed, EBSCOhost (including MEDLINE, CINAHL, APA PsycInfo, etc.), Web of Science (WoS) and Scopus. Parameters and indexes included Morris water maze, passive avoidance test, acetylcholinesterase activity, interleukin 1 (IL-1), tumour necrosis factor-alpha (TNF-α), MAPK, malondialdehyde (MDA), glutathione (GSH), reactive oxygen species (ROS) and mitochondria membrane potential (MMP). RESULTS A total of 285 documents were identified; however, only ten articles were included and used for meta-analysis. The meta-analytic outcome revealed that HSD did not show any significant effect on memory function, neuroinflammatory biomarkers (IL-1, MAPK) and oxidative stress (GSH, MDA, ROS and MMP) in neuronal cells and tissues. CONCLUSIONS Individual study revealed that HSD showed improved memory function, attenuated neuroinflammation and prevented oxidative damage to neurons. However, a conflicting result was observed from the meta-analytic outcomes which showed that HSD has no significant effect on cognitive impairment, neuroinflammation and oxidative stress-induced neuronal damage. However the contradiction in this finding may be associated with small number of studies included. Hence, more studies on the memory-enhacing effects and anti-neuroinflammatory activity of HSD in preclinical and clinical model are required to validate its neuroprotective effect.
