报道了以半乳糖为原料制得２－亚氨基－２－甲氧乙基－１－硫代－β－Ｄ－半乳吡喃糖苷，再与药用明胶偶联制得半乳糖基明胶（ｇａｌａｃｔｏｓｙｌｇｅｌａｔｉｎ，ＧＧ）的方法，并用９９ｍＴｃ标记后进行了动物肝显像及体内分布试验，结果表明，９９ｍＴｃ－ＧＧ主要集中于肝脏，肝显像清晰，有可能作为一种新的肝受体显像剂。
Reported the use of galactose as raw material to prepare 2-Imino-2-methoxyethyl-1-thio-β-D-galactopyranoside glycoside, and then coupled with the pharmaceutical gelatin to obtain galactosyl gelatin galactosylgelatin and galactosylgelatin (GG)). The hepatic imaging and in vivo distribution of 99mTc-GG were performed. The results showed that 99mTc-GG was mainly localized in the liver and the liver imaging was clear. It may be used as a new hepatic receptor imaging Agent.
