[0043] 2. The preparation method of the new axially substituted phthalocyanine complex of the present invention comprises the following major steps: (a) dichlorosilicon phthalocyanine (or a chloroaluminum phthalocyanine) and the corresponding The reactants are dispersed in a suitable solvent according to a certain molar ratio of feed; (b) in the presence of sodium hydride or potassium carbonate, reflux reaction for 1 hour to 3 days, and monitor the reaction end point by chromatography; (c) by solvent method And / or chromatography to remove excess raw materials and impurities and purify the target product. For the schematic diagram of the reaction, see Figures 19 and 20 of the description.

[0044] The corresponding reactants containing substituents described in the present invention include: sulfamic acid; Glucose; Diethylene glycol butyl ether; 4-ethyl phenol; 4-butyl phenol; 4-aminophenol; 2-ethoxy-4-formylphenol; 2-dimethylaminoethanol; 3-diethylaminophenol; pyrimidinols co...

Embodiment 1

[0048] Stir 0.1g of dichlorosilicon phthalocyanine, 0.3g of sulfamic acid, and 20mg of NaH in 10ml of toluene, reflux for 3 days, remove the solvent by rotary evaporation under reduced pressure, add 100ml of water to the solid, filter, and dissolve the filter cake with dichloromethane, Separation and purification by silica gel column chromatography, the eluent is ethanol, after vacuum drying, a dark blue bis(aminosulfonyl)silyl phthalocyanine was obtained with a yield of 38.3%.

Embodiment 2

[0050] Stir 0.1g of dichlorosilicon phthalocyanine, 10ml of diethylene glycol butyl ether, and 20mg of NaH in 10ml of toluene, reflux for 3 days, remove the solvent by rotary evaporation under reduced pressure, add 100ml of water to the solid, filter, and dissolve the filter cake with dichloromethane Afterwards, it was separated and purified by silica gel chromatography, and the eluent was chloroform.

Abstract

An axial substituted phthalocyanine complex, its manufacture and applications in optical dynamics therapy are disclosed. It is prepared by: refluxing silicon dichloride phthalocyanine and monoaluminium phthalocyanine with substitutes contained appropriate compounds and sodium hydrogen or potassium carbonate in appropriate solvent for a certain time, washing with solvent, separating through liquid chromatography, and purifying to obtain products. The complex is prepared simply and quickly, uneasy to be agglomerated, strong optical sensitive, valuble as a drug in optical dynamic treatment. Its structure is clear without isomer.

Description

Technical field: [0001] The present invention relates to an axially substituted phthalocyanine complex, its preparation method and its application in photodynamic therapy. Background technique: [0002] Photodynamic therapy (Photodynamic Therapy), in essence, is the application of the photosensitization reaction of photosensitizers in the medical field. The process of photodynamic therapy is to first inject the photosensitizer into the body, and after a period of time (this waiting time is to allow the drug to be relatively enriched in the target body), the target body is irradiated with light of a specific wavelength (for the target body in the body cavity). The light source can be introduced by means of interventional technology such as optical fiber), and the photosensitizer enriched in the target body is excited by light, which inspires a series of photophysical and photochemical reactions, generates active oxygen, and then destroys the target body (such as cancer cells ...
