Abstract

The invention discloses water-soluble porphyrin gold (III) anticancer compounds and a preparation method thereof, and belongs to the technical field of medicine preparation. The preparation method comprises the following steps of: reacting pyridyl, acyl, nitro and sulfo tetraphenyl porphyrin compounds are reacted with potassium chloroaurate to synthesize porphyrin gold chloride, and generating various salts to obtain a class of novel water-soluble porphyrin gold (III) compounds. In vitro S108 cell detection data proves that the compounds synthesized by the method have higher inhibition effect and have the inhibition rate of 71.133 percent. The method is scientific and reasonable; the prepared product has good water solubility and better anticancer activity; and the preparation process is simple and practicable and suitable for industrial production.

Description

technical field [0001] The invention discloses a water-soluble porphyrin gold (III) anticancer compound and a preparation method thereof, belonging to the technical field of medicine preparation. Background technique [0002] At present, the treatment of malignant tumors is an international problem. For cancer patients who are not suitable for surgery and are not suitable for radiotherapy, the most commonly used method is to apply anti-tumor chemical drugs, referred to as chemotherapy. Chemotherapy can shrink tumors to a certain extent and prevent cancer recurrence and metastasis. However, anti-tumor chemical drugs, including the metal compound cisplatin, have serious toxic and side effects, and the problem of drug resistance is also becoming more and more prominent. Therefore, the continuous development and discovery of new anti-tumor drugs is of great significance for human beings to overcome cancer and prolong life. Studies have shown that tetraphenylporphyrin gold (II...
