Hypericin

Polycyclic dione that has anti-retroviral activity. Inhibits protein kinase C (IC₅₀ = 3.3 µM). Also known to inhibit the protein tyrosine kinase activities of the insulin receptor (IC₅₀ = 20-29 nM), the epidermal growth factor receptor (IC₅₀ = 35 nM), casein kinase II (IC₅₀ = 6 nM), and MAP kinase (IC₅₀ = 4 nM). Useful probe for PKC due to its bright red fluorescence emission and photostability. Also see Pseudohypericin (Cat. No. 539590).

Primary Target
PKC

Target IC₅₀: 3.3 µM, 6 nM, 4 nM, 20-29 nM , 35 nM, against protein kinase C, casein kinase II, MAP kinase, the protein tyrosine activities of the insulin receptor, and the epidermal growth factor receptor, respectively

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.
