Studies on the Hemolytic Mechanism of Antitumor Platinum Complex

항암성 백금화합물의 용혈독성기전에 관한 연구

This study was designed to determine the hemolytic mechanism of antitumor agent tetraphosphine platinum (II) complex (RC-1), which was synthesized recently. Erythrocytes treated with RC-1 showed concentration and time dependent lipid peroxydation, methemoglobin synthesis and hemolysis. And also treatment of radical scavengers showed the inhibitory effect of hemolysis and the decrease of malondialdehyde levels in RC-1 treated erythrocytes. So, the mechanism of hemolysis was considered to be the generation of free radicals, methemoglobin synthesis and the lipid peroxidation of phospholipid which composed of erythrocyte membrane.
