Summary
6-Thioguanine was found to be rapidly absorbed from the blood stream by the tissues and rapidly eliminated in the urine. In tumor it was converted primarily to nucleotides; in intestine, liver, and bone marrow, approximately equal amounts of nucleotides and of thiouric acid were found. Tissue distribution and metabolites found with different times and doses were reported.
