ＷＲ２７２１被碱性磷酸酯酶代谢为有活性的ＷＲ１０６５，清除自由基，降低细胞内氧浓度；而ＷＲ１０６５的代谢产物二硫化物能结合到ＤＮＡ分子上，使它们形成稳定的紧密形式，从而降低细胞毒性化疗药物及电离辐射对它们的破坏。ＷＲ２７２１可提高病人对放疗的耐受，?
WR 2721 by alkaline phosphatase metabolism of active WR 1065, free radicals, reducing intracellular oxygen concentration; and WR1065 metabolites disulfide can bind to the DNA molecules, making them form a stable compact form , Thereby reducing the cytotoxic chemotherapy drugs and ionizing radiation damage to them. WR 2721 can improve the patient’s tolerance to radiotherapy?
