Hypericin

Background: Isolated from Hypericum perforatum, St. John's Wort. Hypericin has been shown to display antiviral and antiretroviral activity. A potent and selective inhibitor of protein kinase C (IC?? = 3.4 uM). Also known to inhibit Casein Kinase II (CKII), MAP Kinase, Insulin R, EGFR, PI-3 Kinase. Displays antineoplastic and antitumor actitities. Most activities require light activation. Induces apoptosis in neuroblastoma cells at 1 uM or above (IC?? = 0.1 uM at 29 mW/cm2 (tungsten light)). Used in photodynamic treatment of tumors and has been reported to be cytotoxic to some tumor cell lines when Hypericin is photoactivated.

Small volumes of Hypericin biochemical vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS842376 is a biochemical targeting Hypericin.
