(R)-Levrazoxane

(R)-Levrazoxane R)-ICRF 186) is enzymatically hydrolysed to one-ring open intermediates by dihydropyrimidine amidohydrolase (DPHase), which is present in the liver and kidney. The radiosensitizing efficiency of (R)-Levrazoxane towards EMT6 mouse mammary tumour cells is greater than that of Dexrazoxane (HY-B0581). (R)-Levrazoxane is promising for research of liver and kidney related diseases.
