Photosensitizer phospholipid compound as well as pharmaceutical composition and application of photosensitizer phospholipid compound

The invention discloses a photosensitizer phospholipid compound, a preparation method of the photosensitizer phospholipid compound, a pharmaceutical composition and application of the photosensitizer phospholipid compound. The pharmaceutical composition is the photosensitizer phospholipid or a combined pharmaceutical composition of the photosensitizer phospholipid and a pharmacologically acceptable carrier, and the pharmaceutical composition is in the form of a liquid preparation, a solid preparation, a semisolid preparation, a capsule, granules, a gel or an injection. The photosensitizer phospholipid compound or a liposome of the photosensitizer phospholipid is applicable to the photodynamic therapy of tumors; the photosensitizer phospholipid compound or the liposome of the photosensitizer phospholipid compound can be rapidly taken by cells and can release a photosensitizer crude drug, and under laser action, the photosensitizer phospholipid compound or the liposome of the photosensitizer phospholipid compound can rapidly release active oxygen to take a strong anti-tumor effect. The photosensitizer phospholipid compound and a liposome nanoparticle thereof can serve as a liquid preparation, a solid preparation, a semisolid preparation, a sterilized preparation and a sterile preparation; and the photosensitizer phospholipid compound and the liposome nanoparticle are low in toxicity and are applicable to the efficient treatment of various tumors.
