(1b, 2e, 3f, 4c, 5d) carrying ether tethers with hydroxyl and methoxy groups, have been synthesized from pyridine aldehyde and the respective amines by reductive amination. Their Cu(II) complexes carrying additional nitrato (6a–b) and perchlorato (7a–e) ligands, respectively, have been characterized and subjected to DNA cleavage studies. Since the hydrolytic DNA cleavage activity of 6a is known from
摘要从吡啶醛和相应的胺经还原胺化反应合成了五种带有羟基和甲氧基醚醚的bpa(双(2-picolyl)胺)衍生物(1b,2e,3f,4c,5d)。他们的Cu(II)配合物分别带有额外的硝酸根(6a–b)和高氯根(7a–e)配体,已被鉴定并进行了DNA裂解研究。由于从文献中已知6a的水解DNA切割活性,所以已经进行了包含新型衍生物的进一步实验。这些结果表明,在标准裂解实验中,衍生物7e产生的线性DNA比6a多出10倍。考虑到Cu(II)中心的氧化还原活性,还研究了这种bpa配合物的可能的氧化裂解活性。
