Pharmacology of 6-Thioguanine in Man1
6-Thioguanine (6-TG) was administered to 15 patients with acute leukemia and to 9 with solid tumors in 32 experiments, as part of Phase I testing of 6-TG. 6-TG and metabolites were measured by labeling the 6-TG with radiosulfur. The levels of 6-TG and metabolites were measured in blood and urine after p.o. and i.v. dosage. Incorporation into DNA and RNA of the bone marrow was measured. Blood le...
متن کاملEffect of 6-Thioguanine and Methyl-6-Thioguanine on stability of DNA duplexes
6-Thioguanine (isG) has been used for the past thirty years as an anti-cancer agent in maintenance chemotherapy for childhood acute lymphoblastic leukemia as well as acute myeloid leukemia. Despite its long-standing clinical use, little is understood of the molecular basis of the cytotoxicity associated with 6SG. Research has shown that 6SG is incorporated into DNA during replication after whic...
متن کاملScheduling of arabinosylcytosine and 6-thioguanine therapy.
SUMMARY Mice treated simultaneously with 1-0-D-arabinofuranosyl-cytosine (ara-C) and 6-thioguanine (6-TG) were protected from the lethal effects of 6-TG. No protection was afforded if ara-C was given 16 hr before the 6-TG. DNA synthesis in mouse bone marrow was immediately depressed to 3 to 12% of that of control in various experiments, after treatment with ara-C, 10 to 20 mg/kg; it then reboun...
متن کاملPeliosis hepatis induced by 6-thioguanine administration.
A patient with acute myeloblastic leukaemia developed jaundice revealing peliosis hepatis after receiving 6-thioguanine for two months. Peliosis hepatis was severe and was associated with mild lesions of centrilobular veins. Withdrawal of 6-thioguanine was followed by a progressive improvement of liver dysfunction. This report shows that 6-thioguanine, a thiopurine already reported to be respon...
متن کاملUse of nucleosides in resistance to 6-thioguanine.
Ascites cell tumors were found to cleave thioguanine riboside relatively rapidly. In tumor cell lines lacking the ribonucleotide pyrophosphorylase necessary for formation of thioguanine ribonucleotide, thioguanine riboside was converted to nucleotide to a small extent. This nucleotide formation was enhanced, after a short time lag, by 9-methyl thioguanine. The nucleoside, adenine arabinoside, w...
