06/01/1986 - "35S- and 3H-labeled S-2-(3-methylaminopropylamino)ethylphosphorothioic acid (WR-3689) have been synthesized in our laboratory and used to study organ and cellular level distribution in C3H/Km mice bearing RIF-1 tumors. "
11/01/1986 - "In diffusible substance autoradiographs of 3H WR-3689 labeled tumors, label was generally distributed over cells with no evidence of preferential localization over nuclei."
08/01/1986 - "Three of four tumors examined take up less WR-3689 than the other two protectors. "
11/01/1986 - "On this basis, tumor levels of WR-77913 were 4.5-fold those of WR-2721, and WR-3689 uptake was 2.7-fold greater than uptake of WR-2721. "
11/01/1986 - "Three aminoalkyl phosphorothioates, WR-2721, WR-3689, and WR-77913, were compared as radioprotectors of RIF-1 tumors irradiated in vivo and assayed for cell survival in vitro. "
