Photophysics and mechanism of photoinduced antiviral action of the natural products, hypericin and hypocrellin A

, 1995
Hypericin, a naturally occurring polycyclic quinone in the flower, St. John's Wort, has been shown to inactivate retroviruses such as Equine Infectious Anemia Virus (EIAV) and Human Immunodeficiency Virus (HIV). This inactivation has been shown to depend

Effect of Chelation to Lanthanum Ions on the Photodynamic Properties of Hypocrellin A

, 2016
Hypocrellin A (HA), an efficient phototherapeutic agent, can chelate with lanthanum ion to form a 1:1 complex, which exhibits enhanced 1O2 generation quantum yield, a red-shifted absorption window, greatly improved water solubility, a much lengthened ...

Exploring Ground-State Heterogeneity of Hypericin and Hypocrellin A and B:  Dynamic and 2D ROESY NMR Study [PDF]

, 1999
A NMR study was conducted on the antiviral and antitumor agents hypericin and hypocrellin A and B, whose activity is light induced. Elucidation of the conformational/tautomeric properties of these polycyclic quinones is important for interpreting their ...
