these compounds were investigated in the presence of Fe(II)SO4 and sodium ascorbate. The obtained results indicated that the Fe(II) complexes of those compounds efficiently cleave DNA and that their cleavage was subtle sequence-selective. Therefore, we succeeded in developing compounds that can be used as small-molecule drugs for cancer chemotherapy.
DNA 切割剂如博莱霉素具有潜在的抗癌应用。识别特定序列的 DNA 切割试剂的开发允许开发具有减少副作用的癌症治疗。在这项研究中,为了开发具有特定 DNA 切割活性的新型化合物,我们合成了光学活性双核配体,(1 R ,1' R ,2 R ,2' R )- N 1 , N 1' -( meta/para -亚苯基双(亚甲基))双( N 2 , N 2-双(吡啶-2-基甲基)环己烷-1,2-二胺)及其对映异构体。在 Fe(II)SO 4和抗坏血酸钠存在下研究了这些化合物的 DNA 切割活性。所得结果表明,这些化合物的 Fe(II) 复合物可有效切割 DNA,并且它们的切割具有细微的序列选择性。因此,我们成功地开发出可用作癌症化疗的小分子药物的化合物。
