Description

technical field [0001] The invention relates to a bis[tri(2-methyl-2-phenyl)propyltin] 2,2'-biphenyl dicarboxylate complex, a preparation method thereof, and the bis[tri( Application of 2-methyl-2-phenyl)propyltin]2,2'-biphenyl dicarboxylate in the preparation of antitumor drugs. Background technique [0002] Organotin is a class of metal-organic compounds containing Sn-C bonds, which has high biological activity and has broad application prospects in the fields of sterilization, insecticide, and anticancer drug preparation. Existing studies have shown that the hydrocarbon group R in organotin is the main factor determining the anticancer activity of the compound. For example, the anticancer activity of cyclohexyl, n-butyl and phenyltin compounds is stronger, followed by ethyl, and methyl almost no anticancer activity. The structure of the ligand also plays an important role in the anticancer activity of the complex and the broad spectrum of killing cancer cells. Experimen...
