[0009] In order to overcome the defects of complex composition, unstable structure, difficult preparation, high cost, easy aggregation, poor water solubility, strong skinphototoxicity and side effects in the existing photosensitive drugs, the present invention uses diphenyl dihalogenated porphine compound as an intermediary The phenyl group introduces a polar group as a hydrophilic group and an alkyl group as a hydrophobic group to improve the hydrophilicity of the compound and inhibit the aggregation ability of the compound; in addition, a halogen is introduced at the meso position of the compound to improve the generation ability of active free radicals And photodynamic biological activity, the new compound prepared has stable structure, good hydrophilicity, not easy to aggregate, simple preparation process, low production cost, strong photodynamic effect, and small skin phototoxic side effects. After a lot of creative work, a new compound was synthesized. A series of intermediary diphenyl dihalogenated porphines and amino acid condensate derivatives thereof complete the present invention

Description
technical field [0001] The invention relates to the field of photosensitizing drugs and photodynamic therapy, in particular to a new type of intermediary di(disubstituted) benzene with good stability, simple preparation process, good hydrophilicity, difficult aggregation, good photodynamic effect, and small skinphototoxicity and side effects. Dihalogenated porphine tetrapyrrole derivatives and their applications. Background technique [0002] Photodynamic therapy (PDT) is a promising new method for the diagnosis and treatment of tumors that is booming after traditional surgery, chemotherapy, and radiotherapy. The principle is that after the photosensitizer is intravenously injected into the human body, it can selectively accumulate or retain in the lesion (such as a malignant tumor). The photochemical reaction finally produces reactive oxygen species (such as singlet oxygen) to kill tumors or other pathological hyperplastic tissues. [0003] Photosensitizers, specific wav...
