博来霉素抗生素与DNA形成复合物(参见1)和某些金属离子(2,3)。这些复合物的结合参数已被证实。核磁共振研究(4)表明,博来霉素的联噻唑和末端胺部分与DNA结合;抗生素的某些其他官能团作为金属离子的配体(3,5)。已经确定了博来霉素生物活性的一些结构要求(1,6)。已经比较了各种DNA结合这些抗生素的能力(7)。
The bleomycin antibiotics form complexes with DNA (cf. 1) and with certain metal ions(2,3). Binding parameters for these complexes have been reportedv'I. Nuclear magnetic resonance studies(4) suggest that the bithiazole and terminal amine moieties of the bleomycins bind to DNA; certain other functional groups of the antibiotic serve as ligands for the metal ion(3,5). Some of the structural requirements for biological activity of bleomycin have been established(1,6). Various DNAs have been compared for their ability to bind these antibiotics(7).
