Hypericin is a naturally occurring substance found in the common St. John's Wort (Hypericum species) and can also be synthesized from the anthraquinone derivative emodin. As the main component of Hypericum perforatum, it has traditionally been used throughout the history of folk medicine. In the last three decades, hypericin has also become the subject of intensive biochemical research and is proving to be a multifunctional agent in drug and medicinal applications. Recent studies report…

Origin, Synthesis and Various Mechanisms of Hypericin as Antidepressant, Photosensitizer and Antiviral

This review focuses on the brief history of the Hypericin, its various natural and semisynthetic sources, the precise pharmacokinetics of the hypericin as well as describes the detailed actions of hyperic in as an antidepressant, antiviral and as a phytotoxic agent.

Hypericins as Potential Leads for New Therapeutics

The aim of this review is to analyse the most recent advances in the chemistry and biological activities (in vitro and in vivo) of the pure naphthodianthrones, hypericin and pseudohypericin from H. perforatum.

On the Mechanism of Action of Anti-Inflammatory Activity of Hypericin: An In Silico Study Pointing to the Relevance of Janus Kinases Inhibition

The capability ofhypericin, and some of its analogues and metabolites, to behave as ATP-competitive inhibitor is highlighted providing a likely mechanistic elucidation of anti-inflammatory activity of H. perforatum extracts containing hypericin and related compounds.

Neuroprotective Activity of Hypericum perforatum and Its Major Components

It has been demonstrated that H. perforatum extracts and several of its major molecular components have the ability to protect against toxic insults, either directly, through neuroprotective mechanisms, or indirectly, through is antioxidant properties.

Biosynthesis of hypericins and hyperforins in Hypericum perforatum L. (St. John’s wort) – precursors and genes involved

The present thesis extends knowledge about the biosynthesis of hypericins and hyper forins in H. perforatum by providing new candidate genes for their biosynthesis and by identifying precursors for hyperforins.

Hypericin, a medicinal compound from St. John’s Wort, inhibits genotoxicity induced by mutagenic agents in V79 cells

The results demonstrate the non-photoactivated hypericin toxicological safety limits, its protective effect on DNA damage and provide a basis for future studies that may characterize better its chemopreventive mechanism.

Hypericin in the Light and in the Dark: Two Sides of the Same Coin

The main aim of this review is to summarize the benefits of photoactivated and non-activated hypericin, mainly in preclinical and clinical applications, and to uncover the “dark side” of this secondary metabolite, focusing on MDR mechanisms.

A current update on phytochemistry, pharmacology and herb–drug interactions of Hypericum perforatum

This review aims to highlight the ‘evidence-based’ therapeutic potential of aforementioned phytopharmaceutical, which would accelerate the contemporary pharmaceutical development of this traditional phytomedicine.

Hypericin: Single molecule spectroscopy of an active natural ingredient

Hypericin can be found in nature in Hypericum perforatum (St. John's Wort) and has become subject of intense biochemical research. Studies report of antidepressive, antineoplastic, antitumor and



Hypericin--a new antiviral and antitumor photosensitizer: mechanism of action and interaction with biological macromolecules.

It is presented how an interdisciplinary approach supported by sophisticated techniques of optical spectroscopy and molecular modeling can be effectively applied for the identification of the specific binding sites of the drug in some biomacromolecules as well as for the determination of the physico-chemical mechanism of the biological activity of hypericin.

Mode of Action of Hypericin as an Antiretroviral Agent and Other Relevant Findings

A naturally occurring, polycyclic aromatic dianthraquinone, which is a lipophilic compound soluble in polar organic solvents such as methanol, ethanol, acetone and DMSO and can be synthesized from emodin by an alkaline condensation via a method described by Spitzner.

Alternative pharmacologic mechanisms for Hypericum's antidepressant activity are critically reviewed and the possible importance of GABA receptor binding in the pharmacology of Hypericum is highlighted.

Hypericin and pseudohypericin: pharmacokinetics and effects on photosensitivity in humans.

Doses used in this study were higher than typical doses in current commercial preparations, frequency of side effects was equal to placebo medication and UV light sensitivity was not or only marginally increased, and there was no correlation between total hypericin plasma concentrations and photosensitivity.

Biochemical Activities of Extracts from Hypericum perforatum L

Summary Extracts from the herb “St. John’s wort” (Hypericum perforatum L.) exhibit beneficial effects on patients suffering from mental depressions. Lack of catecholamine neurotransmitters may be one

Hypericin: a potential antiglioma therapy.

Data suggest that the proven safe drug hypericin may have potential as an antiglioma agent; clinical trials are suggested.

St John's wort (Hypericum perforatum L.): a review of its chemistry, pharmacology and clinical properties

Hyperforin, rather than hypericin as originally thought, has emerged as one of the major constituents responsible for antidepressant activity, and further research is required to determine which other constituents contribute to the antidepressant effect.

Antiviral assays on phytochemicals: the influence of reaction parameters.

It is found that the activities of several known antiviral phytochemicals were profoundly affected by the presence of serum components, but in different ways: the terthiophene, alpha-terthienyl (alpha-T), was inhibited in a concentration-dependent manner by serum.
