37 results about "Hypericin" patented technology

Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum (Saint John's wort). Hypericin is believed to act as an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.

Application of hyperforin in preparation of medicine for preventing or treating amyotrophic lateral sclerosis

The invention belongs to the technical field of medicines, and discloses application of hyperforin in preparation of a medicine for preventing or treating amyotrophic lateral sclerosis. The hyperforin can improve the survival rate of stable transfection cell lines of amyotrophic lateral sclerosis related cell models (SOD1G93A / TDP43M337V), and the hyperforin is prompted to play a protective role in the two cell models. After the hyperforin is given, the expression levels of HO-1 and Drp1 proteins in SOD1G93A cells are increased, which indicates that the hyperforin has certain antioxidant activity; and mitochondrial division in cells can be inhibited, so that cell apoptosis is inhibited and retarded, and a protection effect is achieved. Hypericin can help to improve the SOD1G93A cell morphology and promote synaptic generation, and it is prompted that hypericin has a positive effect on maintaining normal functions of cells. In conclusion, the hyperforin plays a protective role in an SOD1G93A cell model and a TDP43M337V cell model, and the mechanism of the hyperforin is possibly related to the antioxidant activity, the mitochondrial function improvement and the like of the hyperforin.
