a 4-(2,2,6,6-tetramethyl-1-piperidinooxy) free radical, have been synthesized. These derivatives where the nitroxide group is linked to the end of spacers of various lengths, can be used as probes for the study, by esr spectroscopy, of the intercalation of the heterocyclic moiety of Bleomycin.
已知抗生素抗肿瘤药博来霉素通过将其联苯二唑生色团插入DNA碱基对而与DNA结合。已经合成了四个带有4-(2,2,6,6-四甲基-1-哌啶子基氧基)自由基的自旋标记的噻唑。这些氧化亚氮基团连接到各种长度的间隔基末端的衍生物,可以用作电子探针光谱学研究博来霉素杂环部分插入的探针。
