A novel DNA cleaving agent, N, N'-bis2-[4-(3-aminopropylcarbamoyl)-2, 4'-bithiazol-2'-yl]ethyl}ethylenediamine (1), was synthesized. At 25μM concentration, a significant cleaving activity of 1 for plasmid DNA was observed only in the presence of Co(II). Scavengers of active oxygen species could not inhibit the DNA cleavage by 1.
合成了一种新型 DNA 裂解剂 N,N'-双2-[4-(3-氨基丙基氨基甲酰基)-2,4'-联噻唑-2'-基]乙基}乙二胺(1)。在 25μM 浓度下,只有在 Co(II) 存在的情况下,才能观察到 1 对质粒 DNA 有明显的裂解活性。活性氧清除剂不能抑制 1 对 DNA 的裂解。
