Abstract

The invention discloses an indium compound with 2,6-diacetylpyridine thiosemicarbazone as a ligand and a synthesis method and application of the indium compound. The synthesis method includes the following steps that 2,6-diacetylpyridine is dissolved in ethanol and stirred evenly at 55-65 DEG C to prepare a solution; thiosemicarbazone is added into the prepared solution and is subjected to a reflux stirring reaction at 55-65 DEG C, the mixture is cooled to room temperature after the reaction and poured into a beaker for volatilization, and obtained precipitate is filtered and washed with absolute ethyl alcohol to obtain the ligand; InCl3 is dissolved in a methanol solution and dropwise added into the ethanol solution containing the 2,6-diacetylpyridine thiosemicarbazone ligand, the mixtureis subjected to a reflux stirring reaction at 55-65 DEG C, the reacted solution is filtered into the beaker and sealed by using a preservative film, a plurality of holes are pricked through a needleso that the solution can volatilize at normal temperature for several days, and indium compound crystals are obtained. The synthesized indium compound is applied to in-vivo tumor visual therapy, the tumor change can be monitored in real time, integration of phototherapy and chemotherapy is realized, and diagnosis and treatment are visual.

Description

technical field [0001] The invention relates to the synthesis and application of indium compounds, in particular to an indium compound with 2,6-diacetylpyridine thiosemicarbazone as a ligand, a synthesis method and application thereof. Background technique [0002] In 1978, platinum complexes were approved by the FDA as the first metal anticancer drug. The success of metal platinum complexes in tumor treatment has opened up a research boom in the field of metal complexes in the field of antitumor. For more than half a century, people have successively synthesized complexes of gold, platinum, tin, rhodium, ruthenium and other elements. However, whether it is platinum complexes or other metal complexes, there are limitations, such as large side effects, unclear targets, etc., and it is impossible to realize the integration of diagnosis and treatment. [0003] As a rare metal, indium is widely used in various research fields, but it is rarely used in anti-tumor research. Indi...
