A family of DNA-DNA cross-linking agents has been synthesized, in which 2,3-bis-(hydroxymethyl)-pyrrole is linked to the oligopeptide distamycin. These substances were efficient, sequence selective, DNA-DNA interstrand and intrastrand cross-linking agents. Substance 1a formed interstand and intrastrand cross-links at the sequences 5′ d(CGAATT) and 5′ d(GGAATT), respectively. The lesions from hydrolysis
已经合成了DNA-DNA交联剂家族,其中2,3-双-(羟甲基)-吡咯与寡肽双嘧霉素连接。这些物质是有效的,序列选择性的,DNA-DNA链间和链内交联剂。物质1a分别在序列5'd(CGAATT)和5'd(GGAATT)上形成链间和链内交联。链间和链内交联的DNA的磷酸二酯主链水解产生的损伤是相同的,并具有结构20。物质1a作为交联剂的活性比2,3-双-(羟甲基)-1-甲基吡咯(19)高1000倍。2a的细胞毒性与顺式-DDP相当。
