Five new organogermanium sesquioxides have been synthesized and characterized by elemental analysis and IR spectra.
All the compounds were tested for antitumor activities against KB, HCT, and Bel cells in vitro.
Compound 5 (γ-thiocarbamido propyl germanium sesquioxide) showed excellent antitumor activity, and its inhibition yield to KB, HCT, and Bel cells was 92.9%, 84.9%, and 70.9%, respectively.
A rapid method was described for the labeling compound 5 with T99mc, and the optimum labeling conditions were investigated.
The labeling yield is above 90% in pH 7.0, 20∘C, reaction time greater than 10 minutes, 1 mg of compound 5, and 0.075∼0.1 mg of SnCl2.
The biodistribution of T99mc labeled compound 5 in nude mice bearing human colonic xenografts was studied.
The result showed that the tumor uptakes were 0.73, 0.97, 0.87, and 0.62 ID%/g at 1-hour, 3-hour, 6-hour, and 20-hour postinjection, respectively.
T/NT (the uptake ratio for per gram of tumor over normal tissues) was 18.3 for tumor versus brain and 5.81 for tumor versus muscle at 20-hour postinjection.
The tumor clearance was slow.
The results showed that compound 5 may be developed to be a suitable cancer therapeutic agent.
