Hyperforin (Hyp) is an active compound contained in the extract of Hypericum perforatum, well known for its antidepressant activity. However, Hyp has been found to possess several other biological properties, including inhibitory effects on tumor invasion, angiogenesis, and inflammation. In this
Hyperforin (Hyp), a polyphenol-derivative of St. John's wort (Hypericum perforatum), has emerged as key player not only in the antidepressant activity of the plant but also as an inhibitor of bacteria lymphocyte and tumor cell proliferation, and matrix proteinases. We tested whether as well as
The extract of the herbaceous plant St. John's wort (SJW) and its phloroglucinol component hyperforin (HPF) were previously shown to inhibit cytokine-induced STAT-1 and NF-κB activation and prevent damage in pancreatic β cells. To further clarify the mechanisms underlying their protective effects,
Hyperforin, a major constituent of St. John's Wort (Hypericum perforatum, HP), provides anti-inflammatory, anti-tumor, and anti-bacterial properties. Previous studies have shown anti-oxidative properties of St. John's Wort extracts; however, its free radical scavenging activity in skin cells or skin
The acylphloroglucinol hyperforin (Hyp) from St. John's wort possesses anti-inflammatory and anti-carcinogenic properties which were ascribed among others to the inhibition of 5-lipoxygenase. Here, we investigated whether Hyp also interferes with prostanoid generation in biological systems,
The current investigation aimed to scrutinize the neuro-protective effect of hyperforin on β‑amyloid peptide (Aβ)1-42 and H2O2 induced injury in PC12 cells and colchicine induced Alzheimer's disease (AD). PC12 cells were treated with H2O2 and (Aβ)1-42 in the presence of hyperforin. The cell
Hypericum perforatum is a medicinal plant with anti-inflammatory and antioxidant properties, which is commercially available for therapeutic use in Brazil. Herein the effect of H. perforatum extract on paracetamol (acetaminophen)-induced hepatotoxicity, lethality, inflammation, and oxidative stress
Hyperforin, the major lipophilic compound contained in extracts of Hypericum perforatum, is responsible for the antidepressant activity associated with the extract. Recently, several other biological properties of Hyperforin have been unveiled including inhibition of tumour invasion and
The acylphloroglucinol derivative hyperforin is the major lipophilic constituent in the herb Hypericum perforatum (St. John's wort). The aim of the present study was to investigate if hyperforin as well as extracts of H. perforatum can suppresses the activities of 5-lipoxygenase (5-LO) and
Upon activation, microglia, the immunocompetent cells in the brain, get highly phagocytic and release pro-inflammatory mediators like nitric oxide (NO). Excessive NO production is pivotal in neurodegenerative disorders, and there is evidence that abnormalities in NO production and inflammatory
In both type 1 and type 2 diabetes, increased production of cytokines on autoimmune or metabolic basis is supposed to trigger an inflammatory process leading to dysfunction and death of pancreatic beta-cells. Therefore, anti-inflammatory pharmacological approaches aimed at blocking cytokine
St. John's Wort (SJW) has been used medicinally for over 5,000 years. Relatively recently, one of its phloroglucinol derivatives, hyperforin, has emerged as a compound of interest. Hyperforin first gained attention as the constituent of SJW responsible for its antidepressant effects. Since then,
Hyperforin an herbal compound, is commonly used in traditional medicine due to its anti-inflammatory activities. The aim of this study was to use a hyperforin loaded gold nanoparticle (Hyp-GNP) in the treatment of experimental autoimmune encephalomyelitis (EAE) an animal model of multiple sclerosis
The use of natural compounds is an interesting stratagem in the search of drugs with therapeutic potential for the treatment of Alzheimer's disease (AD). We report here the effect of the hyperforin derivative (IDN5706, tetrahydrohyperforin), a semi-synthetic derivative of the St. John's Wort, on the
