LMN 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, H

(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.
LMN系列化合物被用作治疗肝癌的放射性药剂,以及其制造方法被揭示。2-硫乙胺盐酸盐与三苯甲醇反应以保护硫醇,得到2-[(三苯甲基)硫基]乙胺。然后通过2-[(三苯甲基)硫基]乙胺与氯乙酰氯之间的转酰胺反应获得N-[2-((三苯甲基)硫基)乙基]氯乙酰胺。接下来通过N-[2-((三苯甲基)硫基)乙基]氯乙酰胺和2-[(三苯甲基)硫基]乙胺的取代反应产生一种胺-酰胺-硫醇配体-N-[2-((三苯甲基)硫基)乙基][2-((三苯甲基)硫基)乙胺基]乙酰胺。在分别与1-溴四十二烷、1-溴十六烷和乙基-16-溴十六烷酸酯反应后,得到H3LMN系列化合物。这些胺-酰胺-二硫醇四齿配体可以与MO3+(M=Tc或Re)反应,产生电中性络合物。这些络合物具有高脂溶性,使它们可溶于碘油,用于肝癌的放射治疗。
