Bitter yet beneficial: The dual role of dietary alkaloids in managing diabetes and enhancing cognitive function. Biofactors 2024; 50:634-673. [PMID: 38169069 DOI: 10.1002/biof.2034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Accepted: 12/11/2023] [Indexed: 01/05/2024]
Abstract
With the rising prevalence of diabetes and its association with cognitive impairment, interest in the use of dietary alkaloids and other natural products has grown significantly. Understanding how these compounds manage diabetic cognitive dysfunction (DCD) is crucial. This comprehensive review explores the etiology of DCD and the effects of alkaloids in foods and dietary supplements that have been investigated as DCD therapies. Data on how dietary alkaloids like berberine, trigonelline, caffeine, capsaicin, 1-deoxynojirimycin, nuciferine, neferine, aegeline, tetramethylpyrazine, piperine, and others regulate cognition in diabetic disorders were collected from PubMed, Research Gate, Web of Science, Science Direct, and other relevant databases. Dietary alkaloids could improve memory in behavioral models and modulate the mechanisms underlying the cognitive benefits of these compounds, including their effects on glucose metabolism, gut microbiota, vasculopathy, neuroinflammation, and oxidative stress. Evidence suggests that dietary alkaloids hold promise for improving cognition in diabetic patients and could open exciting avenues for future research in diabetes management.

Abstract
BACKGROUND Herbal medicines have been used for the preparation of numerous pharmaceutical products for the treatment of human disorders. Plant-derived products have been used in medicine, nutraceuticals, perfumery, beverages, and cosmetics industries for different purposes. Herbal medicines are mainly derived from different parts of plant materials. Phellodendron bark has been widely known as one of the fundamental herbs of traditional Chinese medicine. Phellodendron bark contains phellodendrine as a main active phytochemical. Phellodendrine ((7S,13aS)-3,10-dimethoxy-7-methyl-6,8,13,13atetrahydro-5H-isoquinolino[2,1-b]isoquinolin-7- ium-2,11-diol), is a quaternary ammonium alkaloid. METHODS This present study aimed to investigate the biological potential and therapeutic effectiveness of phellodendrine in medicine through scientific data analysis of different research works on phellodendrine. The therapeutic value of phellodendrine was analyzed in the present work through scientific data available in Google, Google Scholar, ScienceDirect, and PubMed. All the scientific data on phellodendrine were collected from these databases using the terms herbal drugs and phellodendrine. Pharmacological and analytical data of phellodendrine were analyzed in the present work in order to know the medicinal importance of phellodendrine. RESULTS Scientific data analysis of phellodendrine in the present work signified the biological importance of phellodendrine in medicine. Phellodendrine has numerous beneficial aspects in medicine due to its potential benefits in ulcerative colitis, inflammation, pancreatic cancer, nephritis, immune response, acetylcholinesterase activity, psoriasis, arthritis, atopic dermatitis, and oxidative stress. However, it also has significant effects on eicosanoid generation, neuraminidase-1, inflammasome generation, cytochrome p450, taste receptors, and hepatic gluconeogenesis. Furthermore, scientific data has indicated the presence of phellodendrine in different natural sources, including Phellodendri cortex. Analytical data on phellodendrines has signified their importance in the isolation and separation of pure phytochemicals in medicine. Pharmacokinetic parameters have highlighted the tissue distribution of phellodendrine in different tissue of human beings and higher animals. CONCLUSION In the present work, scientific data analysis has indicated the biological importance, pharmacological activities, and analytical aspects of phellodendrine in medicine.

CNS & NEUROLOGICAL DISORDERS DRUG TARGETS 2024; 23:773-783. [PMID: 37073143 DOI: 10.2174/1871527322666230417083053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 01/21/2023] [Accepted: 01/24/2023] [Indexed: 04/20/2023]
Abstract
BACKGROUND Cholinesterase (ChE) inhibitors used currently in clinics for the treatment of Alzheimer's disease (AD) are the most prescribed drug class with nitrogen-containing chemical formula. Galanthamine, the latest generation anti-ChE drug, contains an isoquinoline structure. OBJECTIVE The aim of the current study was to investigate the inhibitory potential of thirty-four isoquinoline alkaloids, e.g. (-)-adlumidine, β-allocryptopine, berberine, (+)-bicuculline, (-)-bicuculline, (+)-bulbocapnine, (-)-canadine, (±)-chelidimerine, corydaldine, (±)-corydalidzine, (-)-corydalmine, (+)-cularicine, dehydrocavidine, (+)-fumariline, (-)-fumarophycine, (+)-α-hydrastine, (+)-isoboldine, 13-methylcolumbamine, (-)-norjuziphine, norsanguinarine, (-)-ophiocarpine, (-)-ophiocarpine-Noxide, oxocularine, oxosarcocapnine, palmatine, (+)-parfumine, protopine, (+)-reticuline, sanguinarine, (+)-scoulerine, (±)-sibiricine, (±)-sibiricine acetate, (-)-sinactine, and (-)-stylopine isolated from several Fumaria (fumitory) and Corydalis species towards acetyl- (AChE) and butyrylcholinesterase (BChE) by microtiter plate assays. The alkaloids with strong ChE inhibition were proceeded to molecular docking simulations as well as in silico toxicity screening for their mutagenic capacity through VEGA QSAR (AMES test) consensus model and VEGA platform as statistical approaches. The inputs were evaluated in a simplified molecular input-line entry system (SMILES). METHODS ChE inhibition assays indicated that the highest AChE inhibition was caused by berberine (IC50: 0.72 ± 0.04 μg/mL), palmatine (IC50: 6.29 ± 0.61 μg/mL), β-allocryptopine (IC50: 10.62 ± 0.45 μg/mL), (-)-sinactine (IC50: 11.94 ± 0.44 μg/mL), and dehydrocavidine (IC50: 15.01 ± 1.87 μg/mL) as compared to that of galanthamine (IC50: 0.74 ± 0.01 μg/mL), the reference drug with isoquinoline skeleton. Less number of the tested alkaloids exhibited notable BChE inhibition. Among them, berberine (IC50: 7.67 ± 0.36 μg/mL) and (-)-corydalmine (IC50: 7.78 ± 0.38 μg/mL) displayed a stronger inhibition than that of galanthamine (IC50: 12.02 ± 0.25 μg/mL). The mutagenic activity was shown for β-allocryptopine, (+)- and (-)-bicuculline, (±)-corydalidzine, (-)-corydalmine, (+)-cularicine, (-)- fumarophycine, (-)-norjuziphine, (-)-ophiocarpine-N-oxide, (+)-scoulerine, (-)-sinactine, and (-)- stylopine by means of in silico experiments. RESULTS The results obtained by molecular docking simulations of berberine, palmatine, and (-)- corydalmine suggested that the estimated free ligand-binding energies of these compounds inside the binding domains of their targets are reasonable to make them capable of establishing strong polar and nonpolar bonds with the atoms of the active site amino acids. CONCLUSION Our findings revealed that berberine, palmatin, and (-)-corydalmine stand out as the most promising isoquinoline alkaloids in terms of ChE inhibition. Among them, berberine has displayed a robust dual inhibition against both ChEs and could be evaluated further as a lead compound for AD.

Gut fungi differentially response to the antipyretic (heat-clearing) and diaphoretic (exterior-releasing) traditional Chinese medicines in Coptis chinensis-conditioned gut microbiota. Front Pharmacol 2022; 13:1032919. [DOI: 10.3389/fphar.2022.1032919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Accepted: 10/31/2022] [Indexed: 11/19/2022] Open
Abstract
Antipyretic (heat-clearing) and diaphoretic (exterior-releasing) drugs are two main groups of traditional Chinese medicines (TCMs) possessing anti-microbes and anti-inflammation effects, with the former mainly through clearing pyrogens while the latter through promoting diaphoresis. Although anti-microorganism is a common action of these two kinds of TCMs, their difference in antimicrobial spectrums and their interactions when combinedly used remain unclear. Herein, we prepared aqueous extracts from Coptis chinensis (HL) and other antipyretic or diaphoretic TCMs, orally administrated them to C57BL/6 mice at a clinical dose for fourteen days, and analyzed their impaction on both gut bacteria and fungi using full-length 16 S rRNA gene sequencing and internal transcribed spacer 1/2 (ITS1/2) gene sequencing, respectively. Oral administration of HL significantly changed the structure of gut bacteria but showed little influence on gut fungi. Co-treatment with antipyretic or diaphoretic TCMs alleviated the impact of HL on gut bacteria to a similar degree. However, combined with either heat-clearing or exterior-releasing TCMs significantly strengthened the influence of HL on gut fungi, with the latter superior to the former. The antipyretic TCMs enriched Penicillium spp. while diaphoretic TCMs promoted Fusarium spp. Further analysis revealed that the diaphoretic TCMs-enriched fungi Fusarium spp. were positively related to Akkermansia spp., a beneficial bacterium that interacts with Toll-like receptor 4 (TLR4) and regulates thermogenesis, thus providing a potential linkage with their pro-diaphoresis effect. Together, our results reveal that gut fungi differentially respond to the impact of heat-clearing and exterior-releasing TCMs on Coptis chinensis-conditioned gut microbiota, which provides insights into their functional characteristics.

Abstract
This study aimed to optimize the ultrasonic-assisted extraction of the anti-Vibrio parahaemolyticus substances of Phellodendri Chinensis Cortex (ASPC), identify their active substances, and investigate their application in shrimp storage. The ultrasonic-assisted extraction conditions of ASPC were optimized through a single-factor experiment combined with response surface methodology. The optimal parameters were the ethanol concentration of 81%, the ultrasonic power of 500 W, the temperature of 80°C, the extraction time of 23 min, and the liquid/solid ratio 25 ml/g. The antibacterial zone diameter of the obtained extract determined by agar well diffusion method was 15.56 ± 0.22 mm, which was not significantly different from the predicted value (15.92 mm). Berberine was identified as one of the main chemical components of ASPC through high-performance liquid chromatography combined with standard control. The minimum inhibitory concentrations of ASPC and berberine determined by the tube dilution method were 0.25 and 0.03 mg/ml, respectively. The application of ASPC in shrimp storage showed that it could effectively inhibit the proliferation of V. parahaemolyticus on shrimps. This report offers good prospects for the use of Phellodendri Chinensis Cortex as a potential preservative against V. parahaemolyticus in aquatic products.

Identification of the high-yield monacolin K strain from Monascus spp. and its submerged fermentation using different medicinal plants. BOTANICAL STUDIES 2022; 63:20. [PMID: 35779152 PMCID: PMC9250582 DOI: 10.1186/s40529-022-00351-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 06/25/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Medical plants confer various benefits to human health and their bioconversion through microbial fermentation can increase efficacy, reduce toxicity, conserve resources and produce new chemical components. In this study, the cholesterol-lowering monacolin K genes and content produced by Monascus species were identified. The high-yield monacolin K strain further fermented with various medicinal plants. The antioxidant and anti-inflammatory activities, red pigment and monacolin K content, total phenolic content, and metabolites in the fermented products were analyzed. RESULTS Monacolin K was detected in Monascus pilosus (BCRC 38072), and Monascus ruber (BCRC 31533, 31523, 31534, 31535, and 33323). It responded to the highly homologous mokA and mokE genes encoding polyketide synthase and dehydrogenase. The high-yield monacolin K strain, M. ruber BCRC 31535, was used for fermentation with various medicinal plants. A positive relationship between the antioxidant capacity and total phenol content of the fermented products was observed after 60 days of fermentation, and both declined after 120 days of fermentation. By contrast, red pigment and monacolin K accumulated over time during fermentation, and the highest monacolin K content was observed in the fermentation of Glycyrrhiza uralensis, as confirmed by RT-qPCR. Moreover, Monascus-fermented medicinal plants including Paeonia lactiflora, Alpinia oxyphylla, G. uralensis, and rice were not cytotoxic. Only the product of Monascus-fermented G. uralensis significantly exhibited the anti-inflammatory capacity in a dose-dependent manner in lipopolysaccharide-induced Raw264.7 cells. The metabolites of G. uralensis with and without fermentation (60 days) were compared by LC/MS. 2,3-Dihydroxybenzoic acid, 3,4-dihydroxyphenylglycol, and 3-amino-4-hydroxybenzoate were considered to enhance the antioxidant and anti-inflammatory ability. CONCLUSIONS Given that highly homologous monacolin K and citrinin genes can be observed in Monascus spp., monacolin K produced by Monascus species without citrinin genes can be detected through the complementary methods of PCR and HPLC. In addition, the optimal fermentation time was important to the acquisition of antioxidants, red pigment and monacolin K. These bioactive substances were significantly affected by medicinal plants over fermentation time. Consequently, Monascus-fermented G. uralensis had a broad spectrum of biological activities.

Abstract
SCOPE Improper expansion of neural stem and progenitor cells during brain development manifests in primary microcephaly. It is characterized by a reduced head circumference, which correlates with a reduction in brain size. This often corresponds to a general underdevelopment of the brain and entails cognitive, behavioral and motoric retardation. In the past decade significant research efforts have been undertaken to identify genes and the molecular mechanisms underlying microcephaly. One such gene set encompasses factors required for DNA replication. Intriguingly, a growing body of evidence indicates that a substantial number of these genes mediate faithful centrosome and cilium function in addition to their canonical function in genome duplication. Here, we summarize, which DNA replication factors are associated with microcephaly syndromes and to which extent they impact on centrosomes and cilia. This article is protected by copyright.

Abstract
Myasthenia Gravis (MG) is a T cell-driven, autoantibody-mediated disease. Here we show that oral Berberine (BBR) ameliorated clinical symptoms of experimental autoimmune myasthenia gravis(EAMG) rat model via decreasing the frequencies of Th1, Th17, Th1/17 cell subsets. JAK-STAT pathway was highlighted by transcriptomic analysis with EAMG mononuclear cells (MNCs). Surface plasmon resonance identified ligand binding interaction between BBR and JAK2, and electrostatic interaction was proposed by molecular dynamic simulation. Reduced phosphorylated JAK1/2/3 and STAT1/3 in MNCs from BBR-fed EAMG rats were demonstrated. These results suggest that BBR might improve EAMG by rebalancing T cell subsets through targeting JAK-STAT pathway.

Abstract
Bark of Phellodendron chinense Schneid. (Rutaceae), called "Huang Bai" in China, is one of the 50 most used Chinese medicines in clinical practice. In this paper, a new isoquinoline alkaloid glycoside was isolated from P. chinense, and its structure was elucidated using spectroscopic method. The compound was eventually identified as (1S, 3"S)-1, 2, 3, 4-tetrahydro-7-hydroxy-1-[(4-hydroxybenzyl) methyl]-2-methyl-8-O-isoquinolinyl-[3-hydroxy-3-methylglutaryl]-β-D-glucopyranoside and named as Phellodendronoside A (PDA). The results of molecular docking showed that PDA could stably bind to an extracellular signal-regulated kinase (ERK), stress-activated protein kinase (JNK) and p38 mitogen-activated protein kinase (p38MAPK) proteins that are closely related to inflammation. Further, the anti-inflammatory activity of PDA was evaluated using the lipopolysaccharide (LPS) induced RAW264.7 macrophage model. We observed that PDA can effectively reduce the levels of nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and decrease the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Moreover, we found that PDA inhibits the activation of ERK, JNK and p38MAPK proteins in the MAPK signaling pathway. Collectively, the present study demonstrates that PDA has excellent anti-inflammatory effect in vitro by inhibiting the overproduction of pro-inflammatory mediators, and its mechanism of action involves suppressing the activation of MAPK pathways, suggesting that PDA may be a potential agent for the treatment of inflammatory illness.

Abstract
Medicinal plants have curative properties due to the presence of various complex chemical substances of different composition, which are found as secondary metabolites in one or more parts of the plant. The diverse secondary metabolites play an important role in the prevention and cure of various diseases including neurodegenerative diseases like Alzheimer's disease. Naturally occurring compounds such as flavonoids, polyphenols, alkaloids, and glycosides found in various parts of the plant and/or marine sources may potentially protect neurodegeneration as well as improve memory and cognitive function. Many natural compounds show anti-Alzheimer activity through specific pharmacological mechanisms like targeting β-amyloid, Beta-secretase 1 and Acetylcholinesterase. In this review, we have compiled more than 130 natural products with a broad diversity in the class of compounds, which were isolated from different sources showing anti- Alzheimer properties.

Abstract
Three undescribed Amarylidaceae alkaloids, named gigantelline, gigantellinine and gigancrinine, were isolated from Crinum jagus (syn. = Crinum giganteum) collected in Senegal, together with the already known sanguinine, cherylline, lycorine, crinine, flexinine and the isoquinolinone derivative hippadine. Gigantelline, gigantellinine and gigancrinine were characterized as 4-(6,7-dimethoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-phenol, its 7-O-demethyl-5ꞌ-hydroxy-4ꞌ-methoxy derivative and 5,6a,7,7a,8a,9-hexahydro-6,9a-ethano[1,3]dioxolo[4,5-j]oxireno[2,3-b]phenanthridin-9-ol, respectively, by using spectroscopic (1D and 2D 1H and 13C NMR and HRESIMS) and chemical methods. Their relative configuration was assigned by NOESY NMR spectra and NMR calculations, while the absolute configuration was assigned using electronic circular dichroism (ECD) experiments and calculations. Sanguinine, cherylline, crinine, flexinine, and the isoquinolinone hippadine, were isolated for the first time from C. jagus. Cherylline, gigantellinine, crinine, flexinine and sanguinine inhibited the activity of AChE in a dose-dependent manner, and inhibition by sanguinine was remarkably effective (IC50 = 1.83 ± 0.01 μM). Cherylline and hippadine showed weak cytotoxicity at 100 μM.

JOURNAL OF INTEGRATIVE MEDICINE-JIM 2020; 18:125-151. [PMID: 32005442 DOI: 10.1016/j.joim.2020.01.004] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Accepted: 12/04/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND A growing number of epidemiological studies indicate that metabolic syndrome (MetS) and its associated features play a key role in the development of certain degenerative brain disorders, including Alzheimer's disease and vascular dementia. Produced by several different medicinal plants, berberine is a bioactive alkaloid with a wide range of pharmacological effects, including antidiabetic effects. However, it is not clear whether berberine could prevent the development of dementia in association with diabetes. OBJECTIVE To give an overview of the therapeutic potential of berberine as a treatment for dementia associated with diabetes. SEARCH STRATEGY Database searches A and B were conducted using PubMed and ScienceDirect. In search A, studies on berberine's antidementia activities were identified using "berberine" and "dementia" as search terms. In search B, recent studies on berberine's effects on diabetes were surveyed using "berberine" and "diabetes" as search terms. INCLUSION CRITERIA Clinical and preclinical studies that investigated berberine's effects associated with MetS and cognitive dysfunction were included. DATA EXTRACTION AND ANALYSIS Data from studies were extracted by one author, and checked by a second; quality assessments were performed independently by two authors. RESULTS In search A, 61 articles were identified, and 22 original research articles were selected. In search B, 458 articles were identified, of which 101 were deemed relevant and selected. Three duplicates were removed, and a total of 120 articles were reviewed for this study. The results demonstrate that berberine exerts beneficial effects directly in the brain: enhancing cholinergic neurotransmission, improving cerebral blood flow, protecting neurons from inflammation, limiting hyperphosphorylation of tau and facilitating β-amyloid peptide clearance. In addition, evidence is growing that berberine is effective against diabetes and associated disorders, such as atherosclerosis, cardiomyopathy, hypertension, hepatic steatosis, diabetic nephropathy, gut dysbiosis, retinopathy and neuropathy, suggesting indirect benefits for the prevention of dementia. CONCLUSION Berberine could impede the development of dementia via multiple mechanisms: preventing brain damages and enhancing cognition directly in the brain, and indirectly through alleviating risk factors such as metabolic dysfunction, and cardiovascular, kidney and liver diseases. This study provided evidence to support the value of berberine in the prevention of dementia associated with MetS.

Wang & P. K. Hsiao through UPLC-MS combined with an acetylcholinesterase inhibition assay in vitro. JOURNAL OF ETHNOPHARMACOLOGY 2019; 245:112185. [PMID: 31446073 DOI: 10.1016/j.jep.2019.112185] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 08/22/2019] [Accepted: 08/22/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Dichocarpum is endemic to East Asia, and many of them are traditionally used folk medicine in China. Dichocarpum auriculatum (Franch.) W. T. Wang et P. K. Hsiao has the effect of clearing away heat, removing toxicity, and relieving swelling in southwestern China. Intriguingly, its root and whole herb also used as remedy for the neurological disease epilepsy. However, there are not any scientific reports on the phytochemistry and pharmacological activities of D. auriculatum. AIM OF STUDY Traditional and folk medicinal knowledge would be useful for finding new pharmaceutical resources. There are many evidences over the years reported that an interaction probably exists between epilepsy and Alzheimer's disease (AD). The aim of the study was to investigate the potential AChE inhibitors and the phytochemical profiles of the specie D. auriculatum. MATERIALS AND METHODS The AChE inhibitory activity of plant extracts of D. auriculatum and other 6 species from different regions of the genus Dichocarpum were evaluated in vitro assays and the UPLC-Q-TOF-MS technique was used to analyze the chemical constituents. Moreover, UPLC-ESI-MS/MS was used to determine the distribution of 12 standard compounds in samples. RESULTS As a preferred source of potential acetylcholinesterase inhibitors of the genus Dichocarpum, D. auriculatum has been further investigated. The screening results show that the ability of root extracts from D. auriculatum (IC50 = 0.15 mg·mL-1) to inhibit AChE was better than other samples, it is consistent with traditional medicinal records. The phytochemical constituents of D. auriculatum was surveyed firstly by UPLC-Q-TOF-MS analysis, and 36 compounds, including 14 alkaloids, 16 flavonoids, 6 others, were identified tentatively. Further experiments showed that five compounds (columbamine, palmatine, dauricine, jatrorrhizine and berberine) from D. auriculatum were confirmed the potential inhibition of AChE activity in vitro (IC50: 0.24-6.37 μM) and UPLC-ESI-MS/MS results showed that the content of most active compounds in roots was much higher than in aerial parts. Palmatine (IC50 = 0.34 μM) and columbamine (IC50 = 0.24 μM) showed prominent AChE inhibitory activity among the tested compounds. CONCLUSIONS This is the first report about the evaluation of AChE inhibitory activity and phytochemical profiles of D. auriculatum, led to the identification of 36 compounds including alkaloids and flavonoids, and five alkaloids exhibited a significant AChE inhibitory activity and had the potential as AChE inhibitors. This study provided scientific experimental basis for the traditional efficacy of neurological disease of the plant.
