    • A method for preparing a precursor of radioactive 3-iodobenzylguanidine- N,N′-bis(tert-butyloxycarbonyl)-3-(tri-n-butyltin)benzylguanidine) (MSnBG) is revealed. The method includes following steps. Firstly, obtain 3-iodobenzylguanidine bicarbonate by an addition reaction between 3-iodobenzylamine hydrochloride and cyanamide. Use di-tert-butyl dicarbonate as a protecting agent for NH group and convert 3-iodobenzylguanidine bicarbonate into N,N′-bis(tert-butyloxycarbonyl)-N-(3-iodobenzyl) guanidine. At last, under catalysis of bis(triphenylphosphine) palladium dichloride, obtain a final product MSnBG by a substitution reaction between N,N′-bis(tert-butyloxycarbonyl)-N-(3-iodobenzyl) guanidine and bis(tri-n-butyltin). MSnBG is used in no-carrier-added synthesis of [*l]MIBG.

    • A method for preparing a precursor of radioactive 3-iodobenzylguanidine-N,N′-bis(tert-butyloxycarbonyl)-3-(tri-n-butyltin)benzylguanidine) (MSnBG) is revealed. The MSnBG is a precursor of [*I]MIBG that is used as radioactive imaging agents and antineoplastic drugs. The method includes following steps. Firstly, obtain 3-iodobenzylguanidine bicarbonate by an addition reaction between 3-iodobenzylamine hydrochloride and cyanamide. Use di-tert-butyl dicarbonate as a protecting agent for NH group and convert 3-iodobenzylguanidine bicarbonate into N,N′-bis(tert-butyloxycarbonyl)-N-(3-iodobenzyl) guanidine. At last, under catalysis of bis(triphenylphosphine) palladium dichloride, obtain a final product MSnBG by a substitution reaction between N,N′-bis(tert-butyloxycarbonyl)-N-(3-iodobenzyl) guanidine and bis(tri-n-butyltin). MSnBG is used in no-carrier-added synthesis of [*I]MIBG. The [*I]MIBG obtained by this method has better effect on neuroblastoma treatment than that obtained by conventional, carrier-added method.

    • 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.
