[Effect of dioxadet on tumors transplanted to the brain]

A newly-developed antitumor drug Dioxadet is capable of passing the blood-brain barrier. The specific activity of rat brain tissue ranged 8-55% of that of blood at different periods after intraperitoneal injection of 14C-labelled Dioxadet. Dioxadet treatment of mice and rats bearing intracranially-transplanted L1210 leukemia and glioma 35 was followed by a 38-48 and 29% increase in survival, respectively.
