H3LMN series compounds used as radioactive agents for treatment of liver cancer and a manufacturing method thereof are revealed. 2-thioethylamine hydrochloride is reacted with triphenylmethanol for protection of thiol to obtain 2-[(triphenylmethyl)thio]ethylamine. Then obtain N-[2-((triphenylmethyl)thio)ethyl]chloroacetamide by a transamidation reaction between 2-[(triphenylmethyl)thio]ethylamine and chloroactyl chloride. Next produce a amine-amide-thiol ligand-N-[2-((triphenylmethyl)thio)ethyl][2-((triphenylmethyl)thio)ethylamino]acetamide by a substitution reaction of N-[2-((triphenylmethyl)thio)ethyl]chloroacetamide and 2-[(triphenylmethyl)thio]ethylamine. After respective reaction with 1-bromotetradecane, 1-bromohexadecane and ethyl 16-bromohexadecanoate, H3LMN series compounds are obtained. These amine-amide-dithiols quadridentate ligands can react with MO3+ (M=Tc or Re) to produce electrically neutral complexes. The complexes have high lipophilicity, allowing them soluble in lipiodol to be applied to radiation therapy for liver cancer.

The ferromagnetic conveyor belt is wrapped around the first and second rollers. The reducing agent supplier is used for supplying a reducing agent onto the first conveyor belt, the ferromagnetic conveyor belt is capable of conveying the reducing agent from the second roller to the first roller. The solution supplier is configured for supplying the waste solution onto the first conveyor belt.
摘要:
A radioactive mixture and a manufacturing method thereof are disclosed. The radioactive mixture (188Re-MN/Lipiodol mixture) is formed by chelating reaction of MN series compounds that are amine-amide-disulfide amine quadric-dentate chelate ligands with TcO4−/or ReO4−, and then dissolved in Lipiodol. Moreover, the 99mTc/or 188Re of the TcO4−/or ReO4− avoids bone marrow injuries caused by free 90Y. By the feature of the Lipiodol that stays in liver tumors for a long period, the radioactive mixture is applied to treat liver cancers by injection so that injuries caused by surgical operations can be prevented. 188Re-MN/Lipiodol is used for liver cancer, breast cancer or other solid tumors treatment. Re-188 MN or Re-188 MN/Lipiodol can be mixed with anticancer drugs, hydrogel, liposome, micelle or other nano-particles to form the multifunctional therapeutic modality.
