The theoretical simulation revealed that the cis- and trans-（isomers） might co-exist in aqueous solution. A yield higher than 90% under the optimal condition of synthesis was obtained. Good water-solubility was demonstrated. Very little uptakes in muscle, brain, heart and S-180 sarcoma, as well as very rapid blood clearance were revealed in mice. Good accumulation in bone was shown. At 1 h postinjection the bone uptake was 10.9%ID/g. At 3 and 5 h postinjection, bone-to-muscle ratios were 19.0 and 9.3, and bone-to-blood ratios were 31.6 and 28.9, respectively. The result indicates a bone imaging potency of the complex.展开更多
