Abstract
This review collects the synthetic modifications performed on andrographolide, a natural molecule derived from Andrographis paniculata, for oncology applications. Various pharmacomodulations were carried out, and the products were tested on different cancer cell lines. The impact of these modifications was analyzed with the aim of mapping the positions essential for activity to facilitate future research in this field. However, this study makes it clear that, in addition to structural modifications of the molecule, which can result in varying degrees of effectiveness in targeting interactions, the lipophilic capacity of the structures obtained through hemisynthesis is of significant importance.

Abstract
Neurotrophins (NGF, BDNF, NT3, NT4) can decrease cell death, induce differentiation, as well as sustain the structure and function of neurons, which make them promising therapeutic agents for the treatment of neurodegenerative disorders. However, neurotrophins have not been very effective in clinical trials mostly because they cannot pass through the blood-brain barrier owing to being high-molecular-weight proteins. Thus, neurotrophin-mimic small molecules, which stimulate the synthesis of endogenous neurotrophins or enhance neurotrophic actions, may serve as promising alternatives to neurotrophins. Small-molecular-weight natural products, which have been used in dietary functional foods or in traditional medicines over the course of human history, have a great potential for the development of new therapeutic agents against neurodegenerative diseases such as Alzheimer's disease. In this contribution, a variety of natural products possessing neurotrophic properties such as neurogenesis, neurite outgrowth promotion (neuritogenesis), and neuroprotection are described, and a focus is made on the chemistry and biology of several neurotrophic natural products.

A behavioral tagging account of kinase contribution to memory formation after spaced aversive training. iScience 2023; 26:107278.

Abstract
Long-term memory (LTM) can be induced by repeated spaced training trials. Using the weak inhibitory avoidance (wIA) task, we showed that one wIA session does not lead to a 24-h LTM, whereas two identical wIA sessions spaced by 15 min to 6 h induce a 24-h LTM. This LTM promotion depends both on hippocampal protein synthesis and the activity of several kinases. In agreement with the behavioral tagging (BT) hypothesis, our results suggest that the two training sessions induce transient learning tags and lead, via a cooperative effect, to the synthesis of plasticity-related proteins (PRPs) that become available and captured by the tag from the second session. Although ERKs1/2 are needed for PRPs synthesis and CaMKs are required for tag setting, PKA participates in both processes. We conclude that the BT mechanism accounts for the molecular constraints underlying the classic effect of spaced learning on LTM formation.

Abstract
Neurodegenerative diseases (NDs) affect millions of people worldwide, and to date, Alzheimer's and Parkinson's diseases are the most common NDs. Of the many risk factors for neurodegeneration, the aging process has the most significant impact, to the extent that it is tempting to consider neurodegenerative disease as a manifestation of accelerated aging. However, genetic and environmental factors determine the course of neurodegenerative disease progression. It has been proposed that environmental stimuli influence neuroplasticity. Some clinical studies have shown that healthy lifestyles and the administration of nutraceuticals containing bioactive molecules possessing antioxidant and anti-inflammatory properties have a preventive impact or mitigate symptoms in previously diagnosed patients. Despite ongoing research efforts, the therapies currently used for the treatment of NDs provide only marginal therapeutic benefits; therefore, the focus is now directly on the search for natural products that could be valuable tools in combating these diseases, including the natural compound Andrographis paniculata (Ap) and its main constituent, andrographolide (Andro). Preclinical studies have shown that the aqueous extract of Ap can modulate neuroinflammatory and neurodegenerative responses, reducing inflammatory markers and oxidative stress in various NDs. Therefore, in this review, we will focus on the molecular mechanisms by which Ap and Andro can modulate the processes of neurodegeneration and neuroinflammation, which are significant causes of neuronal death and cognitive decline.

Abstract
In spite of the progress in treatment strategies, cancer remains a major cause of death worldwide. Therefore, the main challenge should be the early diagnosis of cancer and the design of an optimal therapeutic strategy to increase the patient's life expectancy as well as the continuation of the search for increasingly active and selective molecules for the treatment of different forms of cancer. In the recent decades, research in the field of natural compounds has increasingly shifted towards advanced and molecular level understandings, thus leading to the development of potent anti-cancer agents. Among them is the diterpene lactone andrographolide, isolated from Andrographis paniculata (Burm.f.) Wall. ex Nees that showed shows a plethora of biological activities, including not only anti-cancer activity, but also anti-inflammatory, anti-viral, anti-bacterial, neuroprotective, hepatoprotective, hypoglycemic, and immunomodulatory properties. Andrographolide has been shown to act as an anti-tumor drug by affecting specific molecular targets that play a part in the development and progression of several cancer types including breast, lung, colon, renal, and cervical cancer, as well as leukemia and hepatocarcinoma. This review comprehensively and systematically summarized the current research on the potential anti-cancer properties of andrographolide highlighting its mechanisms of action, pharmacokinetics, and potential side effects and discussing the future perspectives, challenges, and limitations of use.

Abstract
Low-density lipoprotein receptor-associated protein 1 (LRP1) is widely expressed in neurons, microglia and astrocytes. Studies have revealed that the suppression of LRP1 expression in the brain significantly exacerbates Alzheimer's disease (AD)-related neuropathology. Andrographolide (Andro) has been demonstrated to possess neuroprotective properties, although its underlying mechanisms remain largely unknown. This study aims to investigate whether Andro can inhibit neuroinflammation in AD by modulating the LRP1-mediated PPARγ/NF-κB pathway. In Aβ-induced BV-2 cells, Andro was found to increase cell viability and enhance the expression of LRP1, while decreasing the expression of p-NF-κB (p65) and NF-κB(p65), as well as IL-1β, IL-6 and TNF-α levels. In addition, when Aβ was cotreatment with Andro to BV2 cells with either LRP1 or PPARγ knockdown, increased mRNA and protein expression of p-NF-κB(p65) and NF-κB(p65), NF-κB DNA binding activity as well as IL-1β, IL-6 and TNF-α levels were observed. These findings suggested that Andro could attenuate Aβ induced cytotoxicity by reducing neuroinflammation which may be partly attributed to its effects on this LRP1 mediated PPARγ/NF-κB pathway.

NLRP3 Inflammasome’s Activation in Acute and Chronic Brain Diseases—An Update on Pathogenetic Mechanisms and Therapeutic Perspectives with Respect to Other Inflammasomes. Biomedicines 2023; 11:biomedicines11040999. [PMID: 37189617 DOI: 10.3390/biomedicines11040999] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/16/2023] [Accepted: 03/17/2023] [Indexed: 03/29/2023] Open
Abstract
Increasingly prevalent acute and chronic human brain diseases are scourges for the elderly. Besides the lack of therapies, these ailments share a neuroinflammation that is triggered/sustained by different innate immunity-related protein oligomers called inflammasomes. Relevant neuroinflammation players such as microglia/monocytes typically exhibit a strong NLRP3 inflammasome activation. Hence the idea that NLRP3 suppression might solve neurodegenerative ailments. Here we review the recent Literature about this topic. First, we update conditions and mechanisms, including RNAs, extracellular vesicles/exosomes, endogenous compounds, and ethnic/pharmacological agents/extracts regulating NLRP3 function. Second, we pinpoint NLRP3-activating mechanisms and known NLRP3 inhibition effects in acute (ischemia, stroke, hemorrhage), chronic (Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, MS, ALS), and virus-induced (Zika, SARS-CoV-2, and others) human brain diseases. The available data show that (i) disease-specific divergent mechanisms activate the (mainly animal) brains NLRP3; (ii) no evidence proves that NLRP3 inhibition modifies human brain diseases (yet ad hoc trials are ongoing); and (iii) no findings exclude that concurrently activated other-than-NLRP3 inflammasomes might functionally replace the inhibited NLRP3. Finally, we highlight that among the causes of the persistent lack of therapies are the species difference problem in disease models and a preference for symptomatic over etiologic therapeutic approaches. Therefore, we posit that human neural cell-based disease models could drive etiological, pathogenetic, and therapeutic advances, including NLRP3’s and other inflammasomes’ regulation, while minimizing failure risks in candidate drug trials.

Abstract
In Octodon degus, the aging process is not equivalent between sexes and worsens for females. To determine the beginning of detrimental features in females and the ways in which to improve them, we compared adult females (36 months old) and aged females (72 months old) treated with Andrographolide (ANDRO), the primary ingredient in Andrographis paniculata. Our behavioral data demonstrated that age does not affect recognition memory and preference for novel experiences, but ANDRO increases these at both ages. Sociability was also not affected by age; however, social recognition and long-term memory were lower in the aged females than adults but were restored with ANDRO. The synaptic physiology data from brain slices showed that adults have more basal synaptic efficiency than aged degus; however, ANDRO reduced basal activity in adults, while it increased long-term potentiation (LTP). Instead, ANDRO increased the basal synaptic activity and LTP in aged females. Age-dependent changes were also observed in synaptic proteins, where aged females have higher synaptotagmin (SYT) and lower postsynaptic density protein-95 (PSD95) levels than adults. ANDRO increased the N-methyl D-aspartate receptor subtype 2B (NR2B) at both ages and the PSD95 and Homer1 only in the aged. Thus, females exposed to long-term ANDRO administration show improved complex behaviors related to age-detrimental effects, modulating mechanisms of synaptic transmission, and proteins.

Abstract
BACKGROUND High mobility group box 1 (HMGB1) protein is a damage-associated molecular pattern (DAMP) that plays an important role in the repair and regeneration of tissue injury. It also acts as a pro-inflammatory cytokine through the activation of toll-like receptor 4 (TLR4) and receptor for advanced glycation end products (RAGE), to elicit the neuroinflammatory response. HMGB1 may aggravate several cellular responses, which may lead to pathological inflammation and cellular death. Thus, there have been a considerable amount of research into the pathological role of HMGB1 in diseases. However, whether the mechanism of action of HMGB1 is similar in all neurodegenerative disease pathology remains to be determined. OBJECTIVE Therefore, this systematic review aimed to critically evaluate and elucidate the role of HMGB1 in the pathology of neurodegeneration based on the available literature. METHODS A comprehensive literature search was performed on four databases; EMBASE, PubMed, Scopus, and CINAHL Plus. RESULTS A total of 85 articles were selected for critical appraisal, after subjecting to the inclusion and exclusion criteria in this study. The selected articles revealed that HMGB1 levels were found elevated in most neurodegeneration except in Huntington's disease and Spinocerebellar ataxia, where the levels were found decreased. This review also showcased that HMGB1 may act on distinctive pathways to elicit its pathological response leading to the various neurodegeneration processes/ diseases. CONCLUSION While there have been promising findings in HMGB1 intervention research, further studies may still be required before any HMGB1 intervention may be recommended as a therapeutic target for neurodegenerative diseases.

Abstract
The NLRP3 inflammasome is a crucial constituent of the body’s innate immune system, and a multiprotein platform which is initiated by pattern recognition receptors (PRRs). Its activation leads to caspase-1 maturation and release of inflammatory cytokines, interleukin-1β (IL-1β) and IL-18, and subsequently causes pyroptosis. Recently, the excess activation of NLRP3 inflammasome has been confirmed to mediate inflammatory responses and to participate in genesis and development of atherosclerosis. Therefore, the progress on the discovery of specific inhibitors against the NLRP3 inflammasome and the upstream and downstream inflammatory factors has become potential targets for clinical treatment. Here we review the recently described mechanisms about the NLRP3 inflammasome activation, and discuss emphatically the pharmacological interventions using statins and natural medication for atherosclerosis associated with NLRP3 inflammasome.

PHARMACEUTICAL BIOLOGY 2021; 59:232-241. [PMID: 33632062 PMCID: PMC7919883 DOI: 10.1080/13880209.2021.1883678] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 12/05/2020] [Accepted: 01/25/2021] [Indexed: 06/08/2023]
Abstract
CONTEXT Andrographolide (Andro) has a neuroprotective effect and a potential for treating Alzheimer's disease (AD), but the mechanism has not been elucidated. OBJECTIVE The efficacy of Andro on p62-mediated Kelch-like ECH-associated protein 1(Keap1)-Nuclear factor E2 related factor 2 (Nrf2) pathways in the aluminium maltolate (Al(mal)3)-induced neurotoxicity in PC12 cell was explored. MATERIALS AND METHODS PC12 cells were induced by Al(mal)3 (700 μM) to establish a neurotoxicity model. Following Andro (1.25, 2.5, 5, 10, 20, 40 μM) co-treatment with Al(Mal)3, cell viability was detected with MTT, protein expression levels of β-amyloid precursor protein (APP), β-site APP cleaving enzyme 1 (BACE1), Tau, Nrf2, Keap1, p62 and LC3 were measured via western blotting or immunofluorescence analyses. Nrf2, Keap1, p62 and LC3 mRNA, were detected by reverse transcription-quantitative PCR. RESULTS Compared with the 700 μM Al(mal)3 group, Andro (5, 10 μM) significantly increased Al(mal)3-induced cell viability from 67.4% to 91.9% and 91.2%, respectively, and decreased the expression of APP, BACE1 and Keap1 proteins and the ratio of P-Tau to Tau (from 2.75- fold to 1.94- and 1.70-fold, 2.12-fold to 1.77- and 1.56-fold, 0.68-fold to 0.51- and 0.55-fold, 1.45-fold to 0.82- and 0.91-fold, respectively), increased the protein expression of Nrf2, p62 and the ratio of LC3-II/LC3-I (from 0.67-fold to 0.93- and 0.94-fold, 0.64-fold to 0.88- and 0.87-fold, 0.51-fold to 0.63- and 0.79-fold, respectively), as well as the mRNA expression of Nrf2, p62 and LC3 (from 0.48-fold to 0.92-fold, 0.49-fold to 0.92-fold, 0.25-fold to 0.38-fold). Furthermore, Nrf2 and p62 nuclear translocation were increased and keap1 in the cytoplasm was decreased in the presence of Andro. Silencing p62 or Nrf2 can significantly reduce the protein and mRNA expression of Nrf2 and p62 under co-treatment with Andro and Al(mal)3. DISCUSSION AND CONCLUSIONS Our results suggested that Andro could be a promising therapeutic lead against Al-induced neurotoxicity by regulating p62-mediated keap1-Nrf2 pathways.

Abstract
Andrographis paniculata (Burm. f.) Wall. ex Nees, a renowned herb medicine in China, is broadly utilized in traditional Chinese medicine (TCM) for the treatment of cold and fever, sore throat, sore tongue, snake bite with its excellent functions of clearing heat and toxin, cooling blood and detumescence from times immemorial. Modern pharmacological research corroborates that andrographolide, the major ingredient in this traditional herb, is the fundamental material basis for its efficacy. As the main component of Andrographis paniculata (Burm. f.) Wall. ex Nees, andrographolide reveals numerous therapeutic actions, such as antiinflammatory, antioxidant, anticancer, antimicrobial, antihyperglycemic and so on. However, there are scarcely systematic summaries on the specific mechanism of disease treatment and pharmacokinetics. Moreover, it is also found that it possesses easily ignored security issues in clinical application, such as nephrotoxicity and reproductive toxicity. Thereby it should be kept a lookout over in clinical. Besides, the relationship between the efficacy and security issues of andrographolide should be investigated and evaluated scientifically. In this review, special emphasis is given to andrographolide, a multifunctional natural terpenoids, including its pharmacology, pharmacokinetics, toxicity and pharmaceutical researches. A brief overview of its clinical trials is also presented. This review intends to systematically and comprehensively summarize the current researches of andrographolide, which is of great significance for the development of andrographolide clinical products. Noteworthy, those un-cracked issues such as specific pharmacological mechanisms, security issues, as well as the bottleneck in clinical transformation, which detailed exploration and excavation are still not to be ignored before achieving integration into clinical practice. In addition, given that current extensive clinical data do not have sufficient rigor and documented details, more high-quality investigations in this field are needed to validate the efficacy and/or safety of many herbal products.

Abstract
Andrographolide is a labdane diterpenoid isolated from Andrographis paniculata and traditionally used in Chinese and Indian medicine. Reported effects include anti-bacterial, anti-inflammatory and anti-cancer functions. Most of the studies support the hypothesis that andrographolide supplementation stimulates immune system, so the observed effects migh in fact be secondary to the stimulation of defense reactions. As andrographolide is involved in regulation of inflammation, it is not surprising that it is also evaluated in inflammation-mediated diseases such as ulcerative colitis. Anticancer effects of the andrographolide have been tested on various cancer panels. Colon cancer, breast cancer, and head and neck carcinomas were the most investigated, followed by prostate cancer and glioblastoma. The results looked promising. However, problems with solubility and low level of active substance in natural extract leads to preparation of chemical analogs. Objective of this short review is to summarize current knowledge of the biological effects of andragrapholide. We conclude that despite documented effects and some partly characterized mechanisms of action, more research is clearly needed. At present, the doses, types of treatment and possible negative side effects are not yet established. In addition, various isolations and compound formulas have been used for treatment of various diseases, making final conclusions problematic.

Abstract
Neuropsychiatric systemic lupus erythematosus (NPSLE) is the most serious and complicated clinical manifestation of lupus erythematosus. Cognitive dysfunction is the most common symptom of NPSLE. A variety of potential mechanisms or mediators related to the pathogenesis of NPSLE cognitive dysfunction have been proposed. However, the involvement of microglia CD40 has not been reported yet. This study aimed to investigate whether hippocampal microglia CD40 of MRL/MpJ-Faslpr (MRL/lpr) mice was involved in NPSLE cognitive dysfunction. This study found, using quantitative polymerase chain reaction, western blotting and immunohistochemistry, that hippocampal CD40 was aberrantly overexpressed in the MRL/lpr lupus mice. It also determined using flow cytometry and immunofluorescence that the aberrantly overexpressed CD40 was mainly derived from hippocampal microglia. The adeno-associated virus was used to inhibit microglia CD40 expression, and the brain damage and cognitive dysfunction of MRL/lpr mice improved. Also, imiquimod (IMQ)-induced lupus mice had the same NPSLE cognitive dysfunction, brain damage, and overexpressed hippocampal microglia CD40 as MRL/lpr mice. Therefore, IMQ-induced lupus mouse was proposed as one of the mouse models for studying NPSLE cognitive dysfunction for the first time in this study. The findings indicated that hippocampal microglia CD40 was involved in the development of NPSLE cognitive dysfunction, thus providing a novel research direction for the study of the pathogenesis of NPSLE.

Abstract
BACKGROUND Heat shock response (HSR), a component of cellular protein quality control mechanisms, is defective in different neurodegenerative conditions such as Parkinson's disease (PD). Forced upregulation of heat shock factor 1 (HSF1), an HSR master regulator, showed therapeutic promise in PD models. Many of the reported small-molecule HSF1 activators have limited functions. Therefore, identification and understanding the molecular bases of action of new HSF1 activating molecules is necessary. METHOD We used a cell-based reporter system to screen Andrographis paniculata leaf extract to isolate andrographolide as an inducer of HSF1 activity. The andrographolide activity was characterized by analyzing its role in different protein quality control mechanisms. RESULT We find that besides ameliorating the PD in MPTP-treated mice, andrographolide upregulated different machineries controlled by HSF1 and NRF2 in both cell and mouse brain. Andrographolide achieves these functions through mTORC1 activated via p38 MAPK and ERK pathways. NRF2 activation is reflected in the upregulation of proteasome as well as autophagy pathways. We further show that NRF2 activation is mediated through mTORC1 driven phosphorylation of p62/sequestosome 1. Studies with different cell types suggested that andrographolide-mediated induction of ROS level underlies all these activities in agreement with the upregulation of mTORC1 and NRF2-antioxidant pathway in mice. CONCLUSION Andrographolide through upregulating HSF1 activity ameliorates protein aggregation induced cellular toxicity. GENERAL SIGNIFICANCE Our results provide a reasonable basis for use of andrographolide in the therapy regimen for the treatment of PD.

Abstract
Natural product based medicines are being used in India since 12th century BC and their efficacies are well established in Indian traditional medicine system. However, the mechanism of action as per the modern medicinal system was not well reported. Plant-derived natural compounds are very useful for inflammatory disorders and other diseases such as cancer. Various medicines like artemisinin, vincristine, vinblastine, taxol, and so forth, are invaluable contributions of nature to modern medicine. The role of transcription factor NF-κB was well delineated in inflammatory processes. Binding of NF-κB to the promoter site of several inflammatory genes activate them to secrete proinflammatory cytokines and chemokines. Plant derived natural compounds like andrographolide could be useful in inflammatory disorders as it directly inhibit the binding of NF-κB with DNA at promoter site. Transcription factor NF-κB is a master regulator of the proinflammatory gene expression program and since it was suppressed by andrographolide, hence andrographolide is rightly termed as regulator of master regulator.

[PMID: 33309906 DOI: 10.1016/j.neubiorev.2020.12.005] [Citation(s) in RCA: 45] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 12/03/2020] [Accepted: 12/07/2020] [Indexed: 01/28/2023]
Abstract
Survivors of sepsis often develop long-term cognitive impairments. This review aimed at exploring the results of the behavioral tools and tests which have been used to evaluate cognitive dysfunction in different animal models of sepsis. Two independent investigators searched for sepsis- and cognition-related keywords. 6323 publications were found, of which 355 were selected based on their title, and 226 of these were chosen based on manuscript review. LPS was used to induce sepsis in 171 studies, while CLP was used in 55 studies. Inhibitory avoidance was the most widely used method for assessing aversive memory, followed by fear conditioning and continuous multi-trial inhibitory avoidance. With regard to non-aversive memory, most studies used the water maze, open-field, object recognition, Y-maze, plus maze, and radial maze tests. Both CLP and LPS models of sepsis were effective in inducing short- and long-term behavioral impairment. Our findings help elucidate the mechanisms involved in the pathophysiology of sepsis-induced cognitive changes, as well as the available methods and tests used to study this in animal models.

Abstract
Nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein (NLRP) inflammasomes are involved in the molecular pathogenesis of many diseases and disorders. Among NLRPs, the NLRP3 (in humans encoded by the NLRP3 gene) is expressed predominantly in macrophages as a component of the inflammasome and is associated with many diseases, including gout, type 2 diabetes, multiple sclerosis, atherosclerosis, and neurological diseases and disorders. Diterpenes containing repeated isoprenoid units in their structure are a member of some essential oils that possess diverse biological activities and are becoming a landmark in the field of drug discovery and development. This review sketches a current scenario of diterpenes or their derivatives acting through NLRPs, especially NLRP3-associated pathways with anti-inflammatory effects. For this, a literature survey on the subject has been undertaken using a number of known databases with specific keywords. Findings from the aforementioned databases suggest that diterpenes and their derivatives can exert anti-inflammatory effects via NLRPs-related pathways. Andrographolide, triptolide, kaurenoic acid, carnosic acid, oridonin, teuvincenone F, and some derivatives of tanshinone IIA and phorbol have been found to act through NLRP3 inflammasome pathways. In conclusion, diterpenes and their derivatives could be one of the promising compounds for the treatment of NLRP3-mediated inflammatory diseases and disorders.

Efficacy of andrographolide in not active progressive multiple sclerosis: a prospective exploratory double-blind, parallel-group, randomized, placebo-controlled trial. BMC Neurol 2020; 20:173. [PMID: 32380977 PMCID: PMC7203851 DOI: 10.1186/s12883-020-01745-w] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Accepted: 04/23/2020] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic immune mediated disease and the progressive phase appears to have significant neurodegenerative mechanisms. The classification of the course of progressive MS (PMS) has been re-organized into categories of active vs. not active inflammatory disease and the presence vs. absence of gradual disease progression. Clinical trial experience to date in PMS with anti-inflammatory medications has shown limited effect. Andrographolide is a new class of anti-inflammatory agent, that has been proposed as a potential drug for autoimmune disorders, including MS. In the present trial, we perform an exploratory pilot study on the efficacy and safety of andrographolide (AP) compared to placebo in not active PMS. METHODS A pilot clinical trial using 140 mg oral AP or placebo twice daily for 24 months in patients with not active primary or secondary progressive MS was conducted. The primary efficacy endpoint was the mean percentage brain volume change (mPBVC). Secondary efficacy endpoints included 3-month confirmed disability progression (3-CDP) and mean EDSS change. RESULTS Forty-four patients were randomized: 23 were assigned to the AP group, and 21 were assigned to the placebo group. The median baseline EDSS of both groups was 6.0. Annualized mPBVC was - 0.679% for the AP group and - 1.069% for the placebo group (mean difference: -0.39; 95% CI [- 0.836-0.055], p = 0.08, relative reduction: 36.5%). In the AP group, 30% had 3-CDP compared to 41% in the placebo group (HR: 0.596; 95% CI [0.200-1.777], p = 0.06). The mean EDSS change was - 0.025 in the AP group and + 0.352 in the placebo group (mean difference: 0.63, p = 0.042). Adverse events related to AP were mild rash and dysgeusia. CONCLUSIONS AP was well tolerated and showed a potential effect in reducing brain atrophy and disability progression, that need to be further evaluated in a larger clinical trial. TRIAL REGISTRATION ClinicalTrials.gov NCT02273635 retrospectively registered on October 24th, 2014.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 251:112488. [PMID: 31866509 DOI: 10.1016/j.jep.2019.112488] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 12/13/2019] [Accepted: 12/15/2019] [Indexed: 05/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Andrographis paniculata (AP) is a native plant with anti-inflammatory and antioxidant properties and used as an official herbal medicine. Recently more and more researches have indicated that AP shows pharmacological effects on Alzheimer's disease (AD) but its mechanism is unclear. AIMS OF THE STUDY Network pharmacology approach combined with experimental validation was developed to reveal the underlying molecular mechanisms of AP in treating AD. MATERIALS AND METHODS The compounds of AP from TCM database, the AD-related targets from disease database and the targets corresponding to compounds from swissTargetPrediction were collected. Then DAVID database was used for annotation and enrichment pathways, meanwhile the compound-target, protein-protein interaction from String database and compound-target-pathway network was constructed, molecular modeling was performed using Sybyl-x. Okadaic acid (OKA)-induced cytotoxicity model in PC12 cells was established to verify the mechanism of AP and the key proteins were detected by western blotting. RESULTS 28 AP components were identified after ADME filter analysis and 52 targets were gained via mapping predicted targets into AD-related proteins. In addition, after multiple network analysis, the 22 hub target genes were enriched onto pathways involved in AD, such as neuroactive ligand-receptor interaction, serotonergic synapse, Alzheimer's disease, PI3K-Akt and NF-kB signaling pathway. Interestingly, molecular docking simulation revealed that the targets including PTGS2, BACE1, GSK3B and IKBKB had good ability to combine with AP components. Experimental validation in an in vitro system proved that AP treatment obviously increased in levels inactive of p-GSK3β (P < 0.05) and decreased in levels of BACE (P < 0.05), PTGS2 (namely COX2, P < 0.05) and NF-kB protein (P < 0.05) compare with OKA treated group. CONCLUSION Our data provided convincing evidence that the neuroprotective effects of AP might be partially related to their regulation of the APP-BACE1-GSK3B signal axis and inflammation, which should be the focus of study in this field in the future.

Neuroprotective effects of andrographolide on chronic cerebral hypoperfusion-induced hippocampal neuronal damage in rats possibly via PTEN/AKT signaling pathway. Acta Histochem 2020; 122:151514.

Abstract
To explore the potential effects of andrographolide on chronic cerebral hypoperfusion (CCH)-induced neuronal damage as well as the underlying mechanisms. Rat CCH model was established by 2-vessel occlusion (2VO). The CCH rats received andrographolide treatment for 4 weeks. The neuron loss was detected by using neuronal nuclei (NeuN) immunofluorescent staining. The expression levels of phospho-phosphatase and tensin homolog deleted on chromosome ten (p-PTEN), protein kinase B (AKT), p-AKT, and cysteinyl aspartate specific proteinase-3 (Caspase-3) proteins were accessed by Western blotting. Moreover, the neuronal apoptosis of hippocampus tissues was detected via terminal deoxynucleotidyl transferase- mediated dUTP nick end labeling (TUNEL) staining. CCH reduced the number of NeuN-positive cells, while the number was significant increased after andrographolide treatment. CCH increased the proteins expression level of p-PTEN, Caspase-3, and decreased the p-AKT, which were reversed by andrographolide treatment. Furthermore, andrographolide treatment also down-regulated CCH-induced TUNEL-apoptosis rate. Our results suggest that the PTEN/AKT pathway may be modulated by andrographolide and the damaging effects of CCH on hippocampus may be ameliorated by andrographolide treatment. Andrographolide may act as a potential therapeutic approach for chronic ischemic insults.

Abstract
Background: The current and potential uses of adaptogens are mainly related to treatment of stress-induced fatigue, impaired cognitive function, mental illness, and behavioral- and age-related disorders. However, clinical evidence regarding the efficacy of adaptogens is limited. The primary aim of this study is to determine whether a combination of adaptogenic plant extracts from Andrographis paniculata and Withania somnifera (Adaptra® Forte) could be used as effective and safe treatment for impaired cognitive, memory, or learning ability functions and sleep disorders. Methods: The changes in electroencephalogram (EEG) frequency ranges in 17 different brain regions, psychometric tests of cognitive performance, as well as standard questionnaires of assessment of mood and sleep were measured after single and repeated administration of Adaptra® or placebo for four weeks and after a two-week treatment-free follow-up period within a randomized, double-blind, placebo-controlled two-armed cross-over study. Results: Adaptra® Forte significantly improved cognitive performance in the d2-Test for attention and the concentration performance test after four weeks’ treatment, and was positively correlated with increases in δ and θ power in the quantitative EEG compared with placebo during cognitive challenges. Conclusion: The results of this study suggest that Adaptra® Forte exhibits a calming and anxiolytic effect without sedation, and is associated with overall stress-protective activity.

Abstract
BACKGROUND To bridge the knowledge gap, the present study aimed to investigate the effect of different doses of two widely used performance-enhancing drugs 'methamphetamine' (Meth) and 'human chorionic gonadotropin'(hCG) on ex-vivo cultured primary blood cells of young male Indian athletes. METHODS Primary blood mononuclear cells (PBMCs) were isolated and cultured to obtain pure T cells and monocyte-derived macrophages. Immunofluorescence, flow-cytometry, qRT-PCR, Western blot, ELISA and siRNA transfection studies were carried out to evaluate the effect of these two drugs on athletes' blood cells. RESULTS Cell viability studies revealed that Meth at high doses was toxic for PBMCs and showed a significant negative impact on red blood cell fragility but hCG incubation did not result in any cytotoxicity or haemolysis. The current study also demonstrated that Meth incubation significantly affected T cell proliferation, percentage of regulatory T cells (Treg cells), Th17 cells, early activated T cells, ROS generation and mitochondrial dysfunction. On the other hand, hCG treatment upregulated the percentage of Treg cells. Within macrophage cells, Meth incubation upregulated MYD88 dependent TLR4 pathway and decreased the phagocytotic capability of the cells. Both hCG and Meth showed its potential action on alteration the pro/anti-inflammatory cytokine profiling but suppression of TLR4 pathway by RNA interference (TLR4 siRNA) suggested promising future treatment modalities. CONCLUSION This study demonstrated the differential effects of Meth and hCG on immune cells of athlete's blood. Meth acted as an inflammation and T cell dysfunction inducing agent, while hCG acted as an anti-inflammatory immunosuppressive molecule.

Abstract
Cancer immunotherapy has now become a first line therapy for several kinds of tumors. However, the clinical performance of immnuocheckpoint blockade therapy is usually limited by low response rate or side effects including cytokine storm. Andrographolide, a natural diterpenoid from Andrographis paniculata, has been used in Asia for treatment of bronchitis, paristhmitis and bacillary dysentery for its unique anti-inflammatory effect. However, its effect on anti-tumor immunity remains elusive. In this study, we found that andrographolide in combination with anti-PD-1 antibody showed a higher therapeutic benefit than individual therapy in murine xenograft model of CT26 colon cancer. Consequently, andrographolide and anti-PD-1 antibody co-treatment boosted the function of CD4+ and CD8+ T cells evidenced by considerable tissue infiltration, elevated IFN-γ secretion and enhanced expression of cytotoxic T-cell related molecules including FasL, perforin and Granzyme B, which significantly decreases the tumor load. Mechanistically, andrographolide treatment inhibited COX2 activity and PGE2 release both in vivo and in vitro, which augments anti-tumor efficiency of anti-PD-1 therapy. Finally, we confirmed that COX2 level in human colon cancer sample positively correlated with tumor-promoting factors. Our study here provides a potential combination strategy for immunotherapy against colorectal cancer.

Abstract
Ischemic stroke often causes motor and cognitive deficits. Deregulated glia gap junction communication, which is reflected by increased protein levels of glial fibrillary acidic protein (GFAP) and connexin 43 (Cx43), has been observed in ischemic hippocampus and has been associated with cognitive impairment in animal stroke models. Here, we tested the hypothesis that reactive astrocytes-mediated loss of synaptophysin (SYP) and CREB-regulated transcription coactivator 1 (CRTC1) contribute to dysfunction in glia gap junction communication and memory impairment after ischemic stroke. Male Sprague-Dawley rats were subjected to a 90-min middle cerebral artery occlusion (MCAO) with 7-day reperfusion. Fluorocitrate (1 nmol), the reversible inhibitor of the astrocytic tricarboxylic acid cycle, was injected into the right lateral ventricle of MCAO rats once every 2 days starting immediately before reperfusion. The Morris water maze was used to assess memory in conjunction with western blotting and immunostaining to detect protein expression and distribution in the hippocampus. Our results showed that ischemic stroke caused significant memory impairment accompanied by increased protein levels of GFAP and Cx43 in hippocampal tissue. In addition, the levels of several key memory-related important proteins including SYP, CRTC1, myelin basic protein and high-mobility group-box-1 were significantly reduced in the hippocampal tissue. Of note, inhibition of reactive astrocytes with fluorocitrate was shown to significantly reverse the above noted changes induced by ischemic stroke. Taken together, our findings demonstrate that inhibiting reactive astrocytes with fluorocitrate immediately before reperfusion may protect against ischemic stroke-induced memory impairment through the upregulation of CRTC1 and SYP.

Abstract
High mobility group box 1 (HMGB1) is an endogenous alarmin that drives the pathogenesis of neurodegenerative disorders including cognitive decline. Therefore, HMGB1 is thought to be a common biomarker as well as promising therapeutic target for neuroinflammation associated with neurocognitive disorders. Here, for the first time, we have unmasked the potential inhibitory effect of a novel receptor of HMGB1-CXCL12 complex; atypical chemokine receptor 3 (ACKR3/CXCR7) on HMGB1 induced glial phenotype switching, neuroinflammation, and subsequent memory loss. Upregulation of CXCR7 inhibits HMGB1-CXCL12 complex induced peripheral immune cells infiltration to CNS by regulating blood-brain barrier (BBB) integrity in HMGB1 induced dementia model of mice. Whereas, gene knockdown study by RNA interference (non-invasive intranasal delivery to animal model) shows CXCR7 ablation aggravates inflammatory responses in hippocampus region and immune cell infiltration to CNS tissue by breached BBB. This study also indicates the important role of CXCR7 molecule in maintaining CNS homeostasis by balancing M1/M2 microglia, A1/A2 astrocytes, long term potentiation/long term depression markers which ultimately ameliorates HMGB1 induced neurodegeneration, synaptic depression and memory loss (assessed by both radial arm maze and Morris water maze) in male mice model of dementia. Overall, the study summarizes several significant protective functions afforded by CXCR7 against HMGB1 induced disbalance in neuroimmunological axis, neurodegeneration and memory loss and thereby provides a new paradigm for strategic development of novel therapeutics against neurodegenerative diseases with dementia as a common symptom.

Successful Brain Delivery of Andrographolide Loaded in Human Albumin Nanoparticles to TgCRND8 Mice, an Alzheimer's Disease Mouse Model. Front Pharmacol 2019; 10:910. [PMID: 31507412 PMCID: PMC6713928 DOI: 10.3389/fphar.2019.00910] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Accepted: 07/18/2019] [Indexed: 11/29/2022] Open
Abstract
Andrographolide (AG) was encapsulated in human albumin nanoparticles (AG NPs), and their crossing properties of the blood-brain barrier (BBB), brain distribution, and effects in TgCRND8 mice were evaluated. The development of appropriate NP formulations is mandatory because of the scarce BBB permeability properties of AG. Developed NPs had proper size (mean size: 159.2 ± 4.5 nm), size distribution (PDI nearby 0.12 ± 0.01), and ζ potential (-24.8 ± 1.2 mV), which were not affected by sodium fluorescein (NAF) loading. When AG was loaded to NPs, it slightly affected their size (210.4 ± 3.2 nm) and ζ potential (-20.3 ± 1.5) but not the PDI. Both NAF and AG had a remarkable encapsulation efficiency (more than 99%). The in vitro release of AG from the NPs reached the highest percentage (48%) after 24 h, and the Higuchi’s equation was found to be the best fitting model (R2 = 0.9635). Both AG and AG NPs did not alter the viability of N2a murine neuroblastoma cells when compared with the untreated control cells. In the step-down inhibitory avoidance test, AG NPs administered to TgCRND8 mice significantly improved their performance (P < 0.0001), reaching levels comparable to those displayed by wild-type mice. In the object recognition test, treated and untreated animals showed no deficiencies in exploratory activity, directional movement toward objects, and locomotor activity. No cognitive impairments (discrimination score) were detected in TgCRND8 mice (P < 0.0001) treated with AG NPs. After acute intravenous administration (200 µl), NPs loaded with the probe NAF were detected in the brain parenchyma of TgCRND8 mice. Immunofluorescent analyses evidenced the presence of NPs both in the pE3-Aβ plaque surroundings and inside the pE3-Aβ plaque, indicative of the ability of these NPs to cross the BBB and to penetrate in both undamaged and damaged brain tissues. Furthermore, the immunohistochemical analysis of GFAP-positive astrocytes in the hippocampus of Tg mice evidenced the anti-inflammatory activity of AG when AG NPs were intraperitoneally administered. AG was not effective in counteracting amyloid Aβ aggregation and the resulting toxicity but significantly decreased the oxidative stress levels. In conclusion, AG NPs have extraordinary versatility, nontoxicity, nonimmunogenicity, strong biocompatibility, high biodegradability, and astonishing loading capacity of drug.

Abstract
Andrographolide is a medical herbal compound with documented anti-inflammatory activity and therapeutic efficacy in animal models of Alzheimer's disease, traumatic brain injury, and ischemic stroke. The present study examined the potential therapeutic effects of andrographolide on chronic cerebral hypoperfusion (CCH)-induced hippocampal neuronal damage and cognitive dysfunction. A CCH model was established in male Sprague Dawley (SD) rats using 2-vessel occlusion (2VO). After 4 weeks of CCH, spatial learning and memory were assessed in the Morris water maze and structural damage to the hippocampus by hematoxylin and eosin (HE) staining. Astrocyte activation was examined by immunohistochemical staining and Western blotting for glial fibrillary acid protein (GFAP), while expression levels of the pro-inflammatory cytokine-tumor necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1β), the apoptosis effector cysteinyl aspartate specific proteinase-3 (caspase-3), and the neuroprotectant brain-derived neurotrophic factor (BDNF) and the TrkB receptor were estimated by Western blotting. After 4 weeks of CCH, the hippocampus of 2VO rats exhibited marked neurodegeneration as well as elevated GFAP, TNF-α, IL-1β, and caspase-3 compared to Sham controls. In addition, spatial learning was impaired compared to Sham controls. Andrographolide treatment during CCH suppressed astrocyte activation as evidenced by reduced GFAP expression, enhanced expression of BDNF and TrkB, improved impaired spatial learning and memory, and reversed upregulated TNF-α, IL-1β, and caspase-3 expression. These results reveal a potential neuroprotective effect of andrographolide on hippocampal neuronal damage and cognitive impairment from CCH due to suppression of astrocyte activation and enhancement of BDNF-TrkB signaling.

Abstract
Activated microglia and increased brain IL-1β play a main role in cognitive impairment in much pathology. We studied the role of IL-1β in neuroinflammation-induced impairment of the following different types of learning and memory: novel object recognition (NOR), novel object location (NOL), spatial learning, reference memory (RM), and working memory (WM). All these processes are impaired in hyperammonemic rats. We assessed which of these types of learning and memory are restored by blocking the IL-1 receptor in vivo in hyperammonemic rats and the possible mechanisms involved. Blocking the IL-1 receptor reversed microglial activation in the hippocampus, perirhinal cortex, and prefrontal cortex but not in the postrhinal cortex. This was associated with the restoration of NOR and WM but not of tasks involving a spatial component (NOL and RM). This suggests that IL-1β would be involved in neuroinflammation-induced nonspatial memory impairment, whereas spatial memory impairment would be IL-1β-independent and would be mediated by other proinflammatory factors.-Taoro-González, L., Cabrera-Pastor, A., Sancho-Alonso, M., Arenas, Y.

Int J Mol Sci 2018; 19:ijms19092844. [PMID: 30235892 PMCID: PMC6165383 DOI: 10.3390/ijms19092844] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 09/05/2018] [Accepted: 09/15/2018] [Indexed: 01/04/2023] Open
Abstract
Recent studies mentioned that Andrographolide (Andro), the main bioactive component of traditional Chinese medicine Andrographis paniculata, may be a potential natural product for treating Alzheimer's disease, but the underlining mechanism remains to be discovered. In this study, we investigated whether Andro regulates the nuclear factor E2-related factor 2 (Nrf2)/Sequestosome 1 (p62) signaling pathway and activates autophagy to protect neuronal PC12 cells from the toxicity of the β-amyloid (Aβ) peptide. Our results revealed that Andro protected and rescued PC12 cells from Aβ1–42-induced cell death and restored abnormal changes in nuclear morphology, lactate dehydrogenase, malondialdehyde, intracellular reactive oxygen species, and mitochondrial membrane potential. RT-PCR and Western blotting analysis demonstrated that Andro activated autophagy-related genes and proteins (Beclin-1 and LC3); meanwhile, it also augmented the Nrf2 and p62 expression in mRNA and protein levels, and reduced p-tau and p21 protein expression in Aβ1–42-stimulated cells. Then, further study showed that the pre-transfection of cells with Nrf2 small interfering RNA (siRNA) resulted in the downregulation of p62, Beclin-1, and LC3 proteins expression, as well as the upregulation of p21. Furthermore, the pre-transfection of cells with p62 siRNA didn’t block the Nrf2 protein expression, accompanying with an elevated p21. Taken together, these results showed that Andro significantly ameliorated cell death due to Aβ1–42 insult through the activation of autophagy and the Nrf2-mediated p62 signaling pathway.

Abstract
Aim: In this study, we investigated whether andrographolide (Andro) can alleviate neuropathic pain induced by HIV gp120 plus ddC treatment and the mechanism of its action. Methods: The paw withdrawal threshold and the paw withdrawal latency were observed to assess pain behaviors in all groups of the rats, including control group, control combined with Andro treatment group, sham group, gp120 combined with ddC treatment group, gp120 plus ddC combined with A438079 treatment group, and gp120 plus ddC combined with Andro treatment by intrathecally injecting at a dose of 25 μg/20 μl group. The protein expression levels of the P2X7 receptor, tumor necrosis factor-α-receptor (TNFα-R), interleukin-1β (IL-1β), IL-10, phospho-extracellular regulated protein kinases (ERK) (p-ERK) in the L4-L6 dorsal root ganglia (DRG) were measured by western blotting. Real-time quantitative polymerase chain reaction was used to test the mRNA expression level of the P2X7 receptor. Double-labeling immunofluorescence was used to identify the co-localization of the P2X7 receptor with glial fibrillary acidic protein (GFAP) in DRG. Molecular docking was performed to identify whether the Andro interacted perfectly with the rat P2X7 (rP2X7) receptor. Results: Andro attenuated the mechanical and thermal hyperalgesia in gp120+ddC-treated rats and down-regulated the P2X7 receptor mRNA and protein expression in the L4-L6 DRGs of gp120+ddC-treated rats. Additionally, Andro simultaneously decreased the expression of TNFα-R and IL-1β protein, increased the expression of IL-10 protein in L4-L6 DRGs, and inhibited the activation of ERK signaling pathways. Moreover, Andro decreased the co-expression of GFAP and the P2X7 receptor in the SGCs of L4-L6 DRG on 14th day after surgery. Conclusion: Andro decreased the hyperalgesia induced by gp120 plus ddC.
