Abstract

The invention relates to an application of 2,2',2''-((2,4,6-trihydroxybenzene-1,3,5-triyl)tris(methanylylidene))tris(hydrazinecarbothioamide) in the preparation of antitumor drugs, especially in the preparation of anti-liver cancer drugs. Cell proliferation, cell morphology, cell colony formation, apoptosis, cell cycle, molecular biology and other experiments prove that the compound can effectively inhibit the proliferation of tumor cells, inhibit the tumor cell cloning formation, induce tumor cell apoptosis and affect the cycle of the tumor cells, has significant influences on proteins associated with tumor apoptosis, and has significant antitumor activity. The application provides a basis for the development of novel antitumor drugs, and the compound has a good clinical application prospect. The 2,2',2''-((2,4,6-trihydroxybenzene-1,3,5-triyl)tris(methanylylidene))tris(hydrazinecarbothioamide) which can be used as a pharmaceutically active ingredient and a pharmaceutically acceptablecarrier can be used to prepare an antitumor medicinal composition.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to the pharmacological activity and pharmaceutical use of trialdehyde phloroglucinol thiosemicarbazone (I). The compound can be used for preventing and / or treating diseases such as tumors or cancers caused by various factors. Background technique [0002] Liver cancer is one of the common malignant tumors in my country. Liver cancer includes primary liver cancer and metastatic liver cancer. People usually refer to primary liver cancer when they say liver cancer. Primary liver cancer is one of the most common clinical malignant tumors, and its mortality rate is second only to gastric cancer and esophageal cancer. According to the latest statistics, about 600,000 new liver cancer patients are diagnosed every year in the world, ranking fifth among malignant tumors. my country is a big country with hepatitis B. Most of the liver cancer in our country develops on the basi...
