Abstract

The method presented here enables the isolation of three monofunctional adducts. These are: platination of cytosine, adenine and guanosine. The three detected bifunctional complexes were: guanine N7 to N7, adenine N7 to N7 and adenine N7 to N1. A mixed bifunctional complex of guanine and adenosine and the product of polymerization of three adenines and two moieties of cis DDP were also detected. In the peak eluted separately from the guanine standard, no Pt was detected. The sample eluted in this peak had UV spectrum different from the standard and may represent the degraded product of guanine and polymerized Pt.

铂配合物加合物和核酸碱基在Dowex 50w色谱柱上的分离。
本文提出的方法可以分离出三种单功能加合物。它们是:胞嘧啶、腺嘌呤和鸟嘌呤的铂化。检测到的三种双功能复合物分别为:鸟嘌呤N7 ~ N7、腺嘌呤N7 ~ N7和腺嘌呤N7 ~ N1。还检测到鸟嘌呤和腺苷的混合双功能复合物以及三个腺嘌呤和两个顺式DDP片段聚合的产物。在与鸟嘌呤标准品分离洗脱的峰中,未检出铂。该峰洗脱的样品紫外光谱与标准样品不同,可能是鸟嘌呤和聚合铂的降解产物。
