Abstract

The invention discloses a liver tumor cell inhibitor and a preparation method thereof. The inhibitor has chirality and is a complex named as dichloro-2-[2-(hydroxyl)-3-(methoxy)-phenyl]imidazo[4,5-f][1,10]-phenanthroline.S,S-cyclohexanediamine platinum (II). The preparation method comprises the following steps: preparing 2-[2-(hydroxyl)-3-(methoxy)-phenyl]imidazo[4,5-f][1,10]-phenanthroline from [1,10]-phenanthroline-5,6-dione and 2-hydroxyl-3-methoxybenzaldehyde; then adding potassium chloroplatinite to prepare 2-[2-(hydroxyl)-3-(methoxy)-phenyl]imidazo[4,5-f][1,10]-phenanthroline.dichloroplatinum (II); and finally adding cyclohexanediamine so as to obtain the liver tumor cell inhibitor. The complex provided by the invention has excellent antineoplastic activity and is applicable to anti-hepatoma drugs.

Description

technical field [0001] The invention relates to the technical field of anticancer drugs, in particular to an inhibitor of liver cancer cells and a preparation method. Background technique [0002] Liver cancer is a malignant tumor of the liver, which can be divided into two categories: primary and secondary. Primary liver malignant tumors originate from the epithelial or mesenchymal tissues of the liver. The former is called primary liver cancer, which is a malignant tumor with a high incidence in my country and is extremely harmful; the latter is called sarcoma. [0003] At present, the treatment methods for liver cancer include surgery, chemotherapy, radiotherapy, biological therapy, traditional Chinese medicine and other methods. Most of the drugs used in radiotherapy and chemotherapy are chemical drugs, although they can control the development of some cancer cells and relieve symptoms. However, due to the high toxicity and side effects of chemotherapy drugs, great harm...
