The tri(2-methyl-2-phenylpropyl)tin 3, 5-dimethoxybenzoate complex is a complex represented by structural formula (I) shown in the description. The invention further discloses the preparation method of the tri(2-methyl-2-phenylpropyl)tin 3,5-dimethoxybenzoate complexand the application of the tri(2-methyl-2-phenylpropyl)tin 3, 5-dimethoxybenzoate complex in the preparation of antitumor drugs.

Description

technical field [0001] The invention relates to a tris(2-methyl-2-phenylpropyl)tin 3,5-dimethoxybenzoate complex, a preparation method thereof, and the use of the complex in the preparation of antitumor drugs Applications. Background technique [0002] Organotin carboxylates have high biological activity, and have broad application prospects in the fields of sterilization, insecticide, and anticancer drug preparation. Therefore, research on the synthesis, structure and biological activity of organotin carboxylate complexes has been sought by scientists. extensive attention. Existing studies have shown that the hydrocarbon group R in organotin carboxylates is the main factor determining the anticancer activity of the compound. For example, cyclohexyl, n-butyl and phenyltin compounds have stronger anticancer activities, followed by ethyl , the methyl group has almost no anticancer activity, and, because the known organotin compounds generally have strong toxicity, they are l...
