Abstract
Meantime, it is well accepted that hyperforin, the chemical instable phloroglucinol derivative of Hypericum perforatum, St. John's wort, is the pharmacophore of St. John's wort extracts. With the decline of this scientific discussion, another controversial aspect has been arisen, the question regarding the underlying mechanism leading to the pharmacological profile of the plant extract used in therapy of depression. We will summarize the different concepts described for hyperforin's antidepressive activity. Starting with unspecific protein-independent mechanisms due to changes in pH, we will summarize data of protein-based concepts beginning with concepts based on involvement of a variety of proteins and will finally present concepts based on the modulation of a single protein.
