Fourteen gamma-thiazolidine-1,3-dithiolanes were prepared and tested a
s radioprotective agents. The combination within a single molecule of
thiazolidine and dithiolane moieties, both of which are known for thei
r radioprotective properties, was achieved for the first time. Several
molecules show significant radioprotective activity: immediate 4l; de
layed 4b, 4f, 4h; or immediate and prolonged 4a.
