在细胞中,DNA似乎是抗肿瘤药物m-[PtCl 2(NH3)2](cis-DDP)的活性水合形式的主要靶点,2并且药物的细胞毒性可能是cú-Ptn(NH3)2部分的特定双功能结合的结果。3使用酶消化方法已经表明,在DNA与ris-DDP反应时,在相邻鸟嘌呤之间形成铂交联4,5,并且代表超过50%的病变。5这与酶限制性内切酶获得的结果一致(1)(a)Competitoire de chimie de coordination organique et biologique,LA 32。(b)核磁共振仪。(c)Département des recherches physiques,LA 71.

In the cell, DNA appears to be the primary target of the active aquated forms of the antitumor drug m-[PtCl2 (NH3) 2](cis-DDP), 2 and the cytotoxicity of the drug could result of a particular bifunctional binding of the cú-Ptn (NH3) 2 moiety. 3 It has been shown, using enzymatic digestion methods, that platinum cross-links between adjacent guanines are formed upon reaction of DNA with ris-DDP4, 5 and represent more than 50% of the lesions. 5 This is in agreement with the results obtained by enzymatic restriction (1)(a) Laboratoire de chimie de coordination organique et biologique, LA 32.(b) Laboratoire de resonance magnétique nucléaire.(c) Département des recherches physiques, LA 71.(d) Unite de chimie organique ERA 927.(2)(a) Roberts, JJ; Thomson, A.
