Hypocrellin Derivatives

EPR and ENDOR spectra of the semiquinones from a series of hypocrellin derivatives have been obtained following chemical and electrochemical reduction. ... [Pg.21]

The problems of high lipophilicity and subsequent low bioavailability of the perylenequinones have been approached by altering their formulations [23]. Another limitation to the use of perylenequinones as therapeutic agents is the poor extinction coefficient in the longer wavelength of light (650-800 nm) that is needed to penetrate deep tissue. Many derivatives of hypocrellin have been... [Pg.159]
