The present invention discloses a hypocrellin derivative substituted both in a pen-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: ##STR00001## 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.sup.−1cm.sup.−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 pen-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.

The invention discloses a monosubstituted or polysubstituted amphiphilic hypocrellin derivative, and a preparation method and application thereof. The amphiphilic hypocrellin derivative substituted by a group containing PEG, a quaternary ammonium salt or the like prepared according to the invention has an obvious red shift in its absorption spectrum and a significantly enhanced molar extinction coefficient, compared with the parent hypocrellin, can efficiently produce singlet state oxygen and other reactive oxygen species under photosensitive conditions; has different amphiphilicities and increased biocompatibility with cells or tissues by regulating its hydrophilicity and hydrophobicity; can meet the requirements of different clinical drugs, and solves the requirements of different drug delivery methods for different drug hydrophilicity and lipophilicity. Under identical conditions, the amphiphilic hypocrellin derivative photosensitizer according to the invention has higher ability to photodynamically inactivate tumor cells than the first and second generation commercial photosensitizers.
