摘要: The present invention discloses a hypocrellin derivative substituted both in a peri-position and in a 2-position by an amino, and a preparation method and use thereof. A general structural formula of the derivative is as represented by formulas I-a to I-d: The hypocrellin derivative substituted both in a peri-position and in a 2-position by an amino prepared in the present invention has a maximum absorption wavelength of 600-650 nm and a molar extinction coefficient reaching about 20000-40000 M−1cm−1. Compared with unmodified hypocrellin or hypocrellin having only a 2-position modified, an absorption spectrum of the derivative is significantly red-shifted and the molar extinction coefficient is greatly improved, and the derivative can efficiently produce reactive oxygen species such as singlet oxygen in a photosensitive condition. In the same condition, the hypocrellin derivative substituted both in a peri-position and in a 2-position by an amino involved in the present invention, when used as a photosensitizer, has a stronger ability to photo-dynamically inactivate tumor cells than the first and second generation commercial photosensitizers.
