Bacopa monnieri confers neuroprotection by influencing signaling pathways associated with interleukin 4, 13 and extracellular matrix organization in Alzheimer's disease: A proteomics-based perspective

Alzheimer's disease, a prevalent neurodegenerative disorder in the elderly, is characterized by the accumulation of senile plaques and neurofibrillary tangles, triggering oxidative stress, neuroinflammation, and neuronal apoptosis. Current therapies focus on symptomatic treatment rather than targeting the underlying disease-modifying molecular mechanisms and are often associated with significant side effects. Bacopa monnieri, a traditional Indian herb with nootropic properties, has shown promise in neurological disorder treatment from ancient times. However, its mechanisms of action in Alzheimer's disease remain elusive. In this study, a cellular model for Alzheimer's disease was created by treating differentiated IMR-32 cells with beta-amyloid, 1–42 peptide (Aβ42). Additionally, a recovery model was established through co-treatment with Bacopa monnieri to explore its protective mechanism. Co-treatment with Bacopa monnieri extract recovered Aβ42 induced damage as evidenced by the decreased apoptosis and reduced reactive oxygen species production. Mass spectrometry-based quantitative proteomic analysis identified 21,674 peptides, corresponding to 3626 proteins from the Alzheimer's disease model. The proteins dysregulated by Aβ42 were implicated in cellular functions, such as negative regulation of cell proliferation and microtubule cytoskeleton organization. The enriched pathways include extracellular matrix organization and interleukin-4 and interleukin-13 signaling. Bacopa monnieri co-treatment showed remarkable restoration of Aβ42 altered proteins, including FOSL1, and TDO2. The protein-protein interaction network analysis of Bacopa monnieri restored proteins identified the hub gene involved in Alzheimer's disease. The findings from this study may open up new avenues for creating innovative therapeutic approaches for Alzheimer's disease.

Evaluation of nephroprotective effect of Bacopa monnieri extract against alcohol induced oxidative stress in rats

Differential Alterations in the Expression of AMPA Receptor and Its Trafficking Proteins in the Hippocampus Are Associated with Recognition Memory Impairment in the Rotenone-Parkinson's Disease Mouse Model: Neuroprotective Role of Bacopa monnieri Extract CDRI 08.

Parkinson's disease (PD), an age-associated neurodegenerative motor disorder, is associated with dementia and cognitive decline. However, the precise molecular insight into PD-induced cognitive decline is not fully understood. Here, we have investigated the possible alterations in the expression of glutamate receptor and its trafficking/scaffolding/regulatory proteins underlying the memory formation and neuroprotective effects of a specialized Bacopa monnieri extract, CDRI-08 (BME) in the hippocampus of the rotenone-induced PD mouse model. Our Western blotting and qRT-PCR data reveal that the PD-induced recognition memory decline is associated with significant upregulation of the AMPA receptor subunit GluR1 and downregulation of GluR2 subunit genes in the hippocampus of rotenone-affected mice as compared to the vehicle control. Further, expressions of thetrafficking proteins are significantly upregulated in the hippocampus of rotenone-affected mice compared to the vehicle control. Our results also reveal that the above alterations in the hippocampus are associated with similar expression patterns of total CREB, pCREB, and BDNF. BME (CDRI-08, 200mg/kg BW) reverses the expression of AMPA receptor subunits, their trafficking proteins differentially, and the transcriptional modulatory proteins depending on whether the BME treatment was given before or after the rotenone treatment. Our data suggest that expression of the above genes is significantly reversed in the BME pre-treated mice subjected to rotenone treatment towards their levels in the control mice compared to its treatment after rotenone administration. Our results provide the possible molecular basis underlying the rotenone-induced recognition memory decline, conditions mimicking the PD symptoms in mouse model and neuroprotective action of bacoside A and bacoside B (58%)-enriched Bacopa monnieri extract (BME) in the hippocampus.

Comparative Metabolomics and Network Pharmacology Analysis Reveal Shared Neuroprotective Mechanisms of Bacopa monnieri (L.) Wettst and Centella asiatica (L.) Urb.

Bacopa monnieri (L.) Wettst and Centella asiatica (L.) Urb., two nootropics, are recognized in Indian Ayurvedic texts. Studies have attempted to understand their action as memory enhancers and neuroprotectants, but many molecular aspects remain unknown. We propose that Bacopa monnieri (L.) Wettst and Centella asiatica (L.) Urb. share common neuroprotective mechanisms. Mass spectrometry-based untargeted metabolomics and network pharmacology approach were used to identify potential protein targets for the metabolites from each extract. Phytochemical analyses and cell culture validation studies were also used to assess apoptosis and ROS activity using aqueous extracts prepared from both herbal powders. Further, docking studies were also performed using the LibDock protocol. Untargeted metabolomics and network pharmacology approach unveiled 2751 shared metabolites and 3439 and 2928 non-redundant metabolites from Bacopa monnieri and Centella asiatica extracts, respectively, suggesting a potential common neuroprotective mechanism among these extracts. Protein-target prediction highlighted 92.4% similarity among the proteins interacting with metabolites for these extracts. Among them, kinases mapped to MAPK, mTOR, and PI3K-AKT signaling pathways represented a predominant population. Our results highlight a significant similarity in the metabolome of Bacopa monnieri (L.) Wettst and Centella asiatica (L.) Urb., and their potential protein targets may be attributed to their common neuroprotective functions.

Therapeutic Efficacy of <i>Bacopa monnieri</i> against Aflatoxin B<Sub>1</sub> Induced Toxicity in Rats

Aflatoxin B1 (AFB1), the most frequently discovered aflatoxin in tainted foods and feed, is considered the most important risk factor. Brahmi (Bacopa monnieri) is a well-known perennial, creeping herb in the Indian Ayurvedic system. Thus, the present study was designed to evaluate the protective efficacy of Brahmi against liver damage induced by Aflatoxin B1. The whole study was conducted in two experiments. The first experiment used phytochemical estimation of BM (Bacopa monnieri). In the second experiment, animals were randomly divided into six groups with six animals in each group. Group 1 served as the control. Group 2 served as per se and received the highest dose of therapy which was 40 mg/kg for 13 days, post orally. Group 3 received AFB1 (200 μg/kg/day) for 13 days, orally Groups 4 to 6 received different doses of Brahmi (20, 30, 40 mg/kg/day PO) for 3 consecutive days after 10 days of exposure to AFB1. All animals were sacrificed after 24 hr of the last treatment. DPPH free radical scavenging activity of the plant was reported in terms of IC50 (45.30 ± 2.52 μg/ml). The presence of flavonoids and protein in the plant was reported in 29.63 ± 1.63 μg Rutin /mg, and 59.72 ± 3.30 μg BSA / mg. Acute studies showed increased lipid peroxidation and a decline in antioxidant status. Alterations in the Liver Function Test (LFT) were also observed. Oral treatment with 20-40 mg/kg Brahmi showed remarkable protection against the toxic effects of Aflatoxin B1. Biochemical results of this study demonstrate that Bacopa monnieri extract possesses protective potential against AFB1-induced hepatotoxicity due to the presence of several bioactive phytochemicals. From this study, we can conclude that treating Bacopa monnieri can protect against AFB1 challenge rats.

Comparative Study on the Effect of Bacopa monniera and Omega3 Fatty Acids on the Cortisol Hormone Level in Cold Stress Induced Wistar Albino Rats

In recent years, researchers have identified several natural compounds that could potentially help to retard mental stress. Extracts of Bacopa monniera (BM), a traditional ayurvedic medicine and omega3 faffy acids (OFA) have been reported to enhance effects mental functions by combating the stress. However, there is still an lacunae studies on which of those two drugs has better results on cortisol hormonal changes due to stress. The current study aimed to compare the effects of BM and omega3 fatty acids on cold stress induced Wistar rats. We divided the animals into seven groups. Group I was control in which rats were kept under ideal laboratory conditions, Group II was given cold water swim stress for a period of one month after which the rats were sacrificed for hormonal assay, Group III in which cold water swim stress given for a month followed by oral administration of normal saline as vehicle for a month, Group IV and V in which cold water swim stress given for a month followed by oral administration of BM extracts 40mg/kg and 80mg/kg respectively as treatment for a month. Group VI and VII includes cold stress followed by oral gavages of OFA 60mg/Kg of Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA) for 2 weeks (short-term model) and 4 weeks (long term model) respectively. After the treatment period blood was collected and cortisol assay was done. The data were compared with those of control rats. The results showed an increase in the cortisol level in the stressed group of rats when compared to the treatment group. These results indicate that oral administration of high dose of BM and long-term administration of OFA improves the cortisol level and helps in controlling the stress in rats.

Investigating Bacopa monnieri L. Therapeutic Potential for the Treatment of Neurological Diseases.

The popular perennial creeping plant known as Bacopa monnieri (also known as Brahmi) is being utilized in the Indian Ayurvedic medicine practice. It has a variety of bioactive phytoconstituents that have been used therapeutically to treat a number of serious illnesses. Ancient Vedic scholars used this herb because of its pharmacological effects, particularly as a nerve booster and nootropic supporter. However, it is vital to comprehend the active phytochemical components of Bacopa monnieri extract (BME) and their molecular mechanisms in order to better grasp the effect of BME on neurological illnesses and diseases. Understanding its active phytochemical constituents and their molecular processes is essential. Numerous clinical investigations indicated that BME may have neuroprotective benefits, so it is worthwhile to re-evaluate this wellknown plant. Here, we focused on neurological problems as we examined the pharmacological and phytochemical characteristics of BME. For their effective usage in neuroprotection and cognition, many clinical concerns and the synergistic potential of Bacopa extract have been investigated. Alzheimer's disease is a neurological condition caused by the production of reactive oxygen species, which also causes amyloid-beta (Aβ) and tau protein aggregation and increases neuro-inflammation and neurotoxicity. Our review offers a more indepth molecular understanding of the neuroprotective functions of BME, which can also be connected to its therapeutic management of neurological illnesses and cognitive-improving effects.

Enhanced Bioavailability and Efficacy of Bacopa Extract and Ebelin Lactone: Preparation and Biological Evaluation

Although Bacopa monnieri extract is well known for its cognitive and memory support, it has received minimal attention in pharmacy due to its terrible palatability and poor bioavailability. This study aimed to develop an improved, cost-effective, and eco-friendly process for the preparation of stable and highly bioavailable non-hygroscopic bacosides enriched fraction in such a manner that it contains a specific amount of Bacoside A3 and jujubogenin, and the aglycone derivative (Ebelin lactone). We prepared two compositions 1 and 2 having Bacoside A3 and jujubogenin: Ebelin lactone ratios 1:1 and 3:1 respectively. The efficacy of these herbal compositions was evaluated independently in comparison to the bioactivity of bacosides (20%), bacosides (50%), and Ebelin lactone. This study also aimed to find a wide range of potential activities of formulated composition, including acetylcholinesterase (AChE) inhibitor activity, anti-oxidant activity, cyclooxygenase (COX) inhibitor activity, and anti-cancer activity. We noted that both compositions worked better than parent Bacopa for biological activity assays but the herbal Bacopa Composition 1 is more potent than Composition 2. Hence, further research on Composition 1 should be explored for its potential to treat conditions such as Alzheimer's and various cancer diseases.

Effect of Bacopa monniera on the Level of Cortisol Hormone in Forced Cold Water Swim Stress Induced Wistar Albino Rats

The human brain remains a mystery even after years of research into the biological processes underlying its specific actions. In recent years, researchers have identified several natural compounds that could potentially help to retard mental deterioration. Extracts of Bacopa monniera, a traditional ayurvedic medicine, have been reported to have memory-enhancing effects in animals. However, there are no studies on bp in cold stress induced neuronal changes in hippocampus have been explored. The current study examined the effects of standardized extract of Bacopa monniera, on Wistar rats. We divided the animals into 4 groups. Group I was control in which rats were kept under ideal laboratory conditions, Group II was given cold water swim stress for a period of one month after which the rats were sacrificed for histological studies to study the changes in the hippocampus caused by cold stress, Group III in which cold water swim stress given for a month followed by oral administration of normal saline as vehicle for a month, Group IV in which cold water swim stress given for a month followed by oral administration of Bacopa monniera, extracts 40mg/kg treatment for a month. Group V in which cold water swim stress given for a month followed by oral administration of Bacopa monniera, extracts 80mg/kg treatment for a month. After the treatment period blood was collected and cortisol assay was done. The data were compared with those of control rats. The results showed an increase in the cortisol level in the stressed group of rats when compared to the treatment group. These results indicate that oral administration of Bacopa monniera, extract improves the cortisol level and helps in controlling the stress in rats.

Evaluating the effects of Bacopa monnieri on cognitive performance and sleep quality of patients with mild cognitive impairment: A triple-blinded, randomized, placebo-controlled trial

IntroductionMild cognitive impairment is the middle level of natural cognitive impairment during primary steps of dementia. There are a few studies about improving the cognitive performance and sleep quality in patients with a limited dementia. So, this study was conducted to evaluate the effects of Bacopa monnieri on cognitive performance and sleep quality of patients with mild cognitive impairment. Materials and methodsIn this study, 62 patients with mild cognitive impairment were categorized into two groups of control and intervention. The intervention group received one pill of 160 mg Bacopa monnieri extract in 2 months, and the control group received a pill containing starch powder. The cognitive impairment and sleep quality was assessed using a questionnaire containing demographic information, Montreal Cognitive Assessment, and the Pittsburg Sleep Quality Index in three time-points of before the study, one months after the intervention and 2 months after the intervention (the end of study). ResultsThe results showed no statistically significant difference between two groups in all three time-points in overall cognitive performance score and its 6 parameters (P > 0.05). While in the field of attention at the end of the first month (P = 0.033) and the end of the second month (P = 0.004), it was significant difference between the study groups. Also, in the field of verbal fluency at the end of the second month, this difference was significant (P = 0.003). The cognitive performance overall score showed no significant difference between two groups in first (P = 0.939) and second time-points (P = 0.661), although it was significant at third time-point (P = 0.029). There was no statistically significant difference between two groups in all time-points for sleep quality overall score (P > 0.05). ConclusionThe results showed that Bacopa monnieri can improve the cognitive performance overall score and some of its parameters, but it had no effect on sleep quality.

Antimicrobial Activity against Antibiotic-resistant Pathogens and Antioxidant Activity and LCMS/MS Phytochemical Content Analysis of Selected Medicinal Plants

Medicinal plants are a major source of numerous therapeutic agents, and the emergence of pathogenic bacteria has rekindled interest in traditional medicine systems as an alternative approach to overcoming resistance. The dried plant material of four medicinal plants, namely Terminalia arjuna (bark), Terminalia bellirica (fruit), Aegle marmelos (leaves), and Bacopa monnieri (leaves), was powdered, and aqueous extracts were prepared. The antimicrobial activity of the extracts was evaluated against three clinically important strains: Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli 385. As E. coli 385 was resistant to the broadest spectrum of antibiotics tested, it was classified as (MDR multi-drug resistant). E. coli, Bacillus subtilis, Mycobacterium smegmatis (MTTC), and Vibrio alginolyticus (ATCC) were also assessed using the agar well diffusion method for zones of inhibition and minimum inhibitory/bactericidal concentration (MIC/MBC). Clinically important strains were found to be sensitive to the aqueous extract of T. bellerica (19.51 ± 0.61 mm) with MICs ranging from 0.31 to 0.62 mg/ml. The MDR strain was also sensitive to Bellirica monnieri (16.10 ± 0.31 mm) aqueous extract. To determine the potential for a wide range of applications, the antioxidant activities of the extracts were evaluated using DPPH, ABTS, and FRAP assays. The T. arjuna plant extract exhibited the highest radical scavenging activity with the lowest EC50 values for DPPH (1.15 ± 0.061 mg/ml) and ABTS (1.02 ± 0.07 mg/ml). The plant extracts were characterized by UV-visible spectroscopy, Fourier-transform infrared spectroscopy, and LC-MS/MS.

Assessment of the mechanistic role of an Indian traditionally used ayurvedic herb Bacopa monnieri (L.)Wettst. for ameliorating oxidative stress in neuronal cells

Ethnopharmacological relevanceThis study has important ethnopharmacological implications since it systematically investigated the therapeutic potential of Bacopa monnieri(L.) Wettst. (Brahmi) in treating neurological disorders characterized by oxidative stress—a growing issue in the aging population. Bacopa monnieri, which is strongly rooted in Ayurveda, has long been recognized for its neuroprotective and cognitive advantages. The study goes beyond conventional wisdom by delving into the molecular complexities of Bacopa monnieri, particularly its active ingredient, Bacoside-A, in countering oxidative stress. The study adds to the ethnopharmacological foundation for using this herbal remedy in the context of neurodegenerative disorders by unravelling the scientific underpinnings of Bacopa monnieri's effectiveness, particularly at the molecular level, against brain damage and related conditions influenced by oxidative stress. This dual approach, which bridges traditional wisdom and modern investigation, highlights Bacopa monnieri's potential as a helpful natural remedy for oxidative stress-related neurological diseases. Aim of the studyThe aim of this study is to investigate the detailed molecular mechanism of action (in vitro, in silico and in vivo) of Bacopa monnieri (L.) Wettst. methanolic extract and its active compound, Bacoside-A, against oxidative stress in neurodegenerative disorders. Materials and methodsROS generation activity, mitochondrial membrane potential, calcium deposition and apoptosis were studied through DCFDA, Rhodamine-123, FURA-2 AM and AO/EtBr staining respectively. In silico study to check the effect of Bacoside-A on the Nrf-2 and Keap1 axis was performed through molecular docking study and validated experimentally through immunofluorescence co-localization study. In vivo antioxidant activity of Bacopa monnieri extract was assessed by screening the oxidative stress markers and stress-inducing hormone levels as well as through histopathological analysis of tissues. ResultsThe key outcome of this study is that the methanolic extract of Bacopa monnieri (BME) and its active component, Bacoside-A, protect against oxidative stress in neurodegenerative diseases. At 100 and 20 μg/ml, BME and Bacoside-A respectively quenched ROS, preserved mitochondrial membrane potential, decreased calcium deposition, and inhibited HT-22 mouse hippocampus cell death. BME and Bacoside-A regulated the Keap1 and Nrf-2 axis and their downstream antioxidant enzyme-specific genes to modify cellular antioxidant machinery. In vivo experiments utilizing rats subjected to restrained stress indicated that pre-treatment with BME (50 mg/kg) downregulated oxidative stress markers and stress-inducing hormones, and histological staining demonstrated that BME protected the neuronal cells of the Cornu Ammonis (CA1) area in the hippocampus. ConclusionsOverall, the study suggests that Bacopa monnieri(L.) Wettst. has significant potential as a natural remedy for neurodegenerative disorders, and its active compounds could be developed as new drugs for the prevention and treatment of oxidative stress-related diseases.

Evaluation of Synergistic Activity of Ethanolic Leaf Extracts of Tephrosia Purpurea and Bacopa Monnieri in Ulcer Induced Rats.

To evaluate synergistic antiulcer activity of ethanolic extracts of Tephrosia purpurea and Bacopa monnieri in ulcer induced rats. Ethanolic leaf extracts of both the plants were administered individually and in combination at a dose of 200mg/kg to ulcer induced male albino rats. Omeprazole 10mg/kg was used as standard. Pylorus ligation method, ethanol and indomethacin induced gastric ulcer models were the different gastric ulcer models selected for the induction of ulcer in rats. Ulcer index, ulcer score, total acidity, pH, percentage protection, volume of gastric juice were the parameters evaluated and compared in different groups in all the models. Decrease in the ulcer score, ulcer index, total acidity was observed and percentage protection was significant(*p<0.05 and p<0.01) with the combination extract compared to group received individual plant extracts. Our results suggested that combination of two medicinal plants showed synergistic anti ulcer activity and decreased the formation of ulcer lesions in rats.

Amelioration of Amyloid-β Induced Alzheimer's Disease by Bacopa monnieri through Modulation of Mitochondrial Dysfunction and GSK-3β/Wnt/β-Catenin Signaling.

Alzheimer's disease (AD) is the most prevalent dementia, affecting a large number of populations. Despite being under scrutiny for decades, an effective therapeutic option is still not available. This study explores the therapeutic role of a nootropic herb Bacopa monnieri (BM) in AD-like pathological conditions produced by injecting preformed amyloid-β42 (Aβ42) fibril bilaterally into hippocampus of Wistar rats, and ethanolic extract of BM is orally administered for 4 weeks. Assessment of behavioral changes reveals that BM treatment ameliorates Aβ42-induced cognitive impairment and compromised explorative behavior. Supplementation of BM also reduces oxidative stress biomarkers, proinflammatory cytokines, and cholinesterase activity in the AD rats. Additionally, BM treatment restores Bcl-2-associated X protein (Bax)/ B-cell lymphoma 2 (Bcl-2) imbalance, increases neurotrophic factors expression, and prevents neurodegeneration validated by quantifying Nissl-positive hippocampal neurons. Interestingly, BM administration eliminates amyloid plaques in the hippocampal region and normalizes the Aβ42-induced increase in phospho-tau and total tau expression. Mechanistic investigations reveal that BM interacts with glycogen synthase kinase (GSK-3β) and restores Wnt/β-catenin signaling. BM has been used in diet as a nootropic herb for several centuries. This study highlights the anti-Alzheimer activity of BM from the behavioral to the molecular level by modulating mitochondrial dysfunction, and GSK-3β mediates the Wnt/β-catenin signaling pathway.

Protective effect of Bacopa monnieri against Methotrexate induced Hepatotoxicity in Wistar rats

Background: Methotrexate (MTX) is an anticancer drug and its clinical efficacy is limited to the toxicity associated with the liver. In this study, we examine the potential role of aqueous leaf extracts of Bacopa monnieri to counter methotrexate-induced hepatotoxicity. Methods: This study was undertaken by considering 36 numbers. Wistar male rats were randomly segregated into six groups, with six rats per group. Groups 1 and 2 were kept as normal controls and methotrexate was treated on the 9th day. While groups 3 and 4 received an aqueous extract of the leaf of B. monnieri at two varied doses of 150 and 300 mg/kg, respectively, as a treatment, Whereas groups 5 and 6 kept B. monnieri perse and the standard hepatoprotective drug silymarin @ 200 mg/kg and experiment was conducted for 14 days period. After the experimental procedure, AST, ALT, TNF-á and IL-10 were measured and histopathology of the liver was done. Result: The present study revealed significant alterations in AST, ALT, TNF-alfa and IL-10 in methotrexate-treated rats (group 2) when compared to group 1 and treatment groups 4 and 5 revealed significant improvement and these results were validated through imaging in the histopathology of the liver. We conclude that Bacopa monnieri can efficiently reduce methotrexate-induced liver inflammation and can be used in the management of hepatotoxicity in the liver.

Maternal stress-induced changes in adolescent and adult offspring: Neurobehavioural improvement and telomere maintenance

Maternal stress (MS) during gestation is known to increase the risk for the development of behavioural and physiological disorders and advances cellular aging. In this study, we investigated whether the supplementation of standardized Bacopa monnieri extract (CDRI-08/BME) or l-Carnosine (L-C) to the mother exposed to social stress during gestation modify the effect on their offspring's neurobehaviour, antioxidant defence gene expression, telomere length, and telomere biology. To test this, timed pregnant rats were subjected to social stress during the gestational day (GD) 16–18. A subset of stressed pregnant rats received either BME [80 mg/kg in 0.5% gum acacia (per-orally; p.o)] or L-C [1 mg/kg (p.o)] every day from GD-10 to until their pup's attained postnatal day (PND)-23. We observed that MS induced anxiety-like behaviour, altered inter-limb coordination, antioxidant defence genes [Superoxide dismutase (SOD1,2), Catalase (CAT), Glutathione peroxidase-3 (GPX3)], telomerase reverse transcriptase (TERT), shelterin complex subunits (TRF1, RAP1B, POT1) protein level and shorten telomere length. Notably, supplementation of BME/L-C dampens the MS, thus the effect on neurobehaviour, antioxidant defence gene expression, and telomere biology is minimized in their offspring. Together, our results suggest that supplementation of BME/L-C during gestation dampens the MS and reduced oxidative stress-mediated changes in telomere shortening/biology and associated neurobehaviour in offspring born following MS.

Synthesis of copper nanoclusters from Bacopa monnieri leaves for fluorescence sensing of dichlorvos.

In this work, a facile one-step green synthesis was developed for the fabrication of blue fluorescent copper nanocluster (Brahmi-CuNCs) from the extract of Bacopa monnieri (common name is Brahmi) via a microwave method. The as-prepared Brahmi-CuNCs emitted blue fluorescence at 452 nm when excited at 352 nm and showed a quantum yield of 31.32%. Brahmi-derived blue fluorescent CuNCs acted as a probe for fluorescence sensing of dichlorvos. Upon the addition of dichlorvos, the blue emission for Brahmi-CuNCs was gradually turned off, favouring establishment of a calibration graph in the range 0.5-100 μM with a detection limit of 0.23 μM. The as-synthesized Brahmi-CuNCs exhibited marked sensitivity and selectivity towards dichlorvos, favourable for assaying dichlorvos in various samples (cabbage, apple juice, and rice).

Effect of Brahmi (Bacopa Monnieri) in the Treatment of Alzheimer's Disease from Ayurvedic Perspective - A Systematic Review

Objectives: Treatment of Alzheimer’s disease is the worldwide problem as it is having major impact on the memory. Ayurveda science describes Brahmi (Bacopa Monnieri) as memory enhancing drug which can improve the memory power in the Alzheimer’s disease. Data Sources: Classical textbooks and published research studies were searched in the context of use of Brahmi (Bacopa Monnieri) in the Alzheimer’s disease. Online search engines namely J gate, Google scholar, PubMed, DHARA online and AYUSH research portal were used for data mining of published research works. Review Methods: References and studies including the effect of Brahmi (Bacopa Monnieri) in the treatment of Alzheimer’s disease were reviewed and reported according to the PRISMA guidelines. We include randomized controlled trials with mild cognitive impairment in Alzheimer’s disease which involves Bacopa Monnieri, its extract or its active ingredients. Results and Discussion: 5 studies found eligible for the search. Two studies used extracts of Bacopa Monnieri extracts while three studies used other drugs in combination with the Bacopa Monnieri extract. The cognitive subscale scores of the Alzheimer’s disease Assessment scale found in one study, mini mental state examination scores were found in three studies. All the studies found a significant difference in statistics. Hence, Brahmi (Bacopa Monnieri) may find to be effective in Alzheimer’s disease and its equivalent disease in Ayurveda. Conclusion: The evidence obtained from the present systematic review is of very low certainty. The evidence from 5 trials suggests that there is a very little difference between Bacopa Monnieri and a placebo or donepezil in the treatment of Alzheimer disease or mild cognitive impairment which needs to find in further future studies No major safety issues were reported in the trials included in this review.

Investigating MARK4 inhibitory potential of Bacopaside II: Targeting Alzheimer's disease

Microtubule affinity regulating kinase 4 (MARK4) is known to hyperphosphorylate tau protein, which subsequently causes Alzheimer's disease (AD). MARK4 is a well-validated drug target for AD; thus, we employed its structural features to discover potential inhibitors. On the other hand, complementary and alternative medicines (CAMs) have been used for the treatment of numerous diseases with little side effects. In this regard, Bacopa monnieri extracts have been extensively used to treat neurological disorders because of their neuroprotective roles. The plant extract is used as a memory enhancer and a brain tonic. Bacopaside II is a major component of Bacopa monnieri; thus, we studied its inhibitory effects and binding affinity towards the MARK4. Bacopaside II show a considerable binding affinity for MARK4 (K = 107 M−1) and inhibited kinase activity with an IC50 value of 5.4 μM. To get atomistic insights into the binding mechanism, we performed Molecular dynamics (MD) simulation studies for 100 ns. Bacopaside II binds strongly to the active site pocket residues of MARK4 and a number of hydrogen bonds remain stable throughout the MD trajectory. Our findings provide the basis for the therapeutic implication of Bacopaside and its derivatives in MARK4-related neurodegenerative diseases, especially AD and neuroinflammation.
