The association of potassium monopersulfate, KHSO5, with a water-soluble manganese porphyrin complex has been recently reported as being a very efficient system for the oxidative cleavage of DNA (Fouquet et al., J. Chem. Soc., Chem. Commun., 1987, 1169); similar results are observed with RNA. As puzzle piece of the mechanism of this oxidative degradation of nucleic acids, we report in the present communication
最近已经报道过一硫酸氢钾KHSO 5与水溶性锰卟啉配合物的结合是对DNA进行氧化裂解的非常有效的系统(Fouquet et al。,J.Chem.Soc。,Chem.Commun。 ,1987,1169);用RNA观察到相似的结果。作为核酸这种氧化降解机理的难题,我们在本通讯中报道了用KHSO 5 / [Mn鉴定作为腺苷5'-单磷酸(AMP)氧化产物的8-羟基腺苷5'-单磷酸。(Mepy)4 P](OAc)5。在不存在锰催化剂的情况下,唯一可检测的化合物是腺苷-N 1-氧化物-5'-单磷酸酯。
